What is the acceleration of a 2000 kg truck that has an engine exert 400 N of
force?

Answers

Answer 1

The acceleration of a 2000 kg truck that has an engine exerts 400 N of force at 0.2 m/s².

Acceleration is the rate of change of the velocity of an item with appreciation to time. Accelerations are vector portions. The orientation of an item's acceleration is given by the orientation of the net pressure appearing on that object.

Calculation:-

mass = 2000 kg

Force = 400 N

acceleration = F/mass

                      =  400/2000

                      = 0.2 m/s²

Acceleration is the charge at which velocity modifications with time, in terms of each speed and route. A factor or an object moving in a straight line is accelerated if it quickens or slows down. movement on a circle is extended despite the fact that the rate is consistent because the course is continually changing.

what if? if oil is spilled on the ground, causing the coefficient of static friction to drop to half the value found in part (b), what is the maximum distance (in m) the firefighter can climb along the ladder from the bottom before the ladder slips?

Answers

The maximum distance the firefighter can climb is 2.623 m.

Calculation:-

Let the maximum height be Dmax

The coefficient of friction is halved thus

[tex]\mu1 = \mu/2 = 0.306 / 2 = 0.153[/tex]

Now,

[tex]NW = \mu1*N = 1330 * 0.153 = 203.49[/tex]

= [tex](Weight of the ladder*cos\theta)* L/2 + (Weight of the man*cos\theta)* dmax - ( NW*sin\theta)* L = 0[/tex]

=  480*cos63 * (14/2) + 850*cos63*dmax - ( 203.49 *sin63 * 14) = 0

= 480*0.454*7 + 850*0.454*dmax = 203.49 *0.891*14

= 1525.44 + 385.9*dmax = 2538.33

= 385.9*dmax = 2538.33 - 1525.44  = 1012.89

= Dmax = 1012.89 / 385.9  = 2.623 m

what two physics mistakes occur in a science fiction movie that shows a distant explosion in outer space, where you see and hear the explosion at the same time?

Answers

The two physics mistakes that occur in science fiction movies that show a distant explosion in outer space, where you see and hear the explosion at the same time are:

Firstly, in outer space, there is no air or other material to propagate sound.

Second, if there were air or any material then the faster-moving light would reach you before the sound.

Moreover, to travel to us from outer space, the wave must be able to travel through regions of space which are essentially a vacuum. Sound requires a medium to propagate in, so we would not be able to hear the explosion.

Sound and light travel at very different speeds - light travels about a million times faster than sound, so the explosion could not be seen and heard at the same time, it would be heard later.

Answers

The momentum of the hockey puck is 18 kgm/s.

Momentum of any object is nothing but the product of mass and velocity. Momentum is a vector quantity so it is having both mass and direction. generally the direction of momentum is the same as the direction of velocity, because mass is a scalar quantity.

It means we can write that,

momentum = mass x velocity

P = mxv

here in the question we have mass 0.12 kg and velocity is 150 m/s, so we can write

P = 0.12 x 150 (kgm/s)

speed of 20km/hr he arrives six minutes late. What is the distance between his house and his
office? Calculate his average speed when he arrives precisely on time. Explain your answer.

Answers

Explanation:

speed = distance/time

distance/speed = distance / distance/time = time

when we define the equations, we must be careful to use the same scales as in the given numbers.

as we are dealing with km/h for speed, we need to have distance measured in km, and time in hours.

6 minutes is therefore 1/10 of an hour (1 hour = 60 minutes).

distance/30 = x - 1/10

distance/20 = x + 1/10

we subtract equation 2 from equation 1 :

distance/30 = x - 1/10

- distance/20 = x + 1/10

-----------------------------------

distance/30 - distance/20 = -2/10

we multiply by 60 to eliminate all fractions :

2×distance - 3×distance = -2×6 = -12

-distance = -12

distance = 12 km

x = the travel time to arrive on time.

distance/30 = x - 1/10

12/30 = x - 1/10

12 = 30x - 3

15 = 30x

x = 15/30 = 0.5 hours = 30 minutes

so, he has half an hour for his 12 km trip to work to arrive precisely on time.

that means his average speed for that must be

12/0.5 = 24/1 = 24 km/h

The electric dipole deals with the separation of positive and negative charges found in electromagnetic systems. A simple example of this system is a pair of charges of equal magnitude and opposite sign, usually separated by a short distance. (A permanent electric dipole is called an electret.)

A magnetic dipole is a closed circuit in the current system. A simple example is a single wire loop with a constant current. An electric or magnetic dipole can be characterized by the vector quantity dipole moment. In a simple electric dipole, the electric dipole moment points from a negative charge to a positive charge and has a magnitude equal to the strength of each charge multiplied by the distance between the charges. (To be exact:

The "dipole limit" should always be considered when defining the dipole moment. For example, the generated charge spacing should converge toward 0, but at the same time the charge strength should diverge toward infinity so that the product does not change. positive constant)

The crankshaft will undergoes 89 revolution.

Revolution can be defined as the action of a celestial body moving along an orbit or elliptical path.

Revolution of the crank shaft can be calculated by the second equation of rotational motion, θ = ut + 0.5 at²

θ = distance covered in radians

u = initial velocity of the crankshaft = 0 rad/sec

t = time taken to complete all the revolutions

a = angular acceleration

Angular acceleration can be calculated by the first equation of rotational motion, a = (v-u)/t

v = 3240 rpm = (3240 * 2 * [tex]\pi[/tex]) / 60 = 339.3 rad/sec

a = (339.3 - 0)/ 3.3

a = 102.81 rad/sec²

what does the mass of a black hole need to be in order for its mass divided by its volume to be equal to the density of water (1g/cm3) ?

Answers

The mass of a black hole needs to be in order for its mass divided by its volume to be equal to the density of water (1g/cm³) is 7x10²¹ solar masses or 1.45 x 10⁵⁵g

A black hole is a collapsed star where all of the mass is concentrated into a single point in space. As it is a point, there is no volume. Therefore the density of the singularity is therefore infinite regardless of mass which is given by,

Density = Mass/Volume

Density =Mass/0

Density=Infinite

However, it is said that black holes have an event horizon, which is said to be the point where light is "captured" by the black hole. If we assume this event horizon is a spherical boundary for the black hole, then we can use its volume for our density calculation instead of the singularity.

Effectively, we could able to calculate the "average" density within the event horizon. The radius of the event horizon is called the Schwarzschild Radius, and can be found using the following formula,

R = 2MG/c²

where M is the mass of gravity, G is the gravitational coefficient and c is the speed of light. The volume of the spherical horizon could be computed as,

V = πR²

On substituting the value of R to this formula we get,

V = π(4M²G²)/c⁴

Density = c⁴/π(4MG²)

M = c⁴/4πPG²

If we consider the density to be the density of water that is 1g/cm², then mass could ve computed as,

[tex]M = \frac{(3*10^{8})^{4} }{3.14*4*1*(6.6743*10^{-11})^{2} } \\M = \frac{(3*10^{8})^{4}}{12.56*44.52*10^{-22}} \\M = \frac{81*10^{32}}{559.2833*10^{-22}}} \\[/tex]

M = 0.14482 x 10⁵⁴

The velocity of sound waves is roughly the same for all wavelengths. Suppose that a sound wave has a wavelength of one meter and a frequency of 1000hz. The wavelength of a 250hz sound wave would then be.

Answers

Answer:

4 m

Explanation:

[tex]v = f \times  λ[/tex]

speed of sound wave (according to question)

= 1 × 1000 = 1000m/s

wavelength is represented by λ

therefore to find the wavelength, divide the speed by the frequency of the second wave given by the question

λ of another wave = 1000 ÷ 250 = 4 m

Speed of sound equals wavelength and frequency. The wavelength of the sound wave if the frequency is 250hz is 4 meters.  

What is the speed of sound waves?

Sound requires a medium to propagate in the form of vibration. It is the pattern of disturbance caused by the movement of energy particles propagating through the medium.

Sound waves can travel in the form of transverse and longitudinal waves. When the sound source continues to vibrate in the medium, the vibrations are propagated in the form of sound waves.

The sound waves travel at different speeds in different mediums. the speed of sound waves remains constant in the same medium. The speed of sound waves is directly proportional to wavelength and frequency.

Wavelength(λ) measures the distance between two crests/ two troughs in a wave and its SI unit is a meter. The frequency (f) of a wave is the number of waves that pass in a certain time and its unit is hertz(Hz). The SI unit of the speed sound wave is m/s.

From the givens,

wavelength(λ) = 1 meter.

frequency (f) = 1000hz.

Speed of wave(v) = wavelength × frequency

                              = 1 × 1000

                           v   = 1000 m/s.

speed of wave = 1000 m/s.

frequency = 250hz

wavelength(λ) = speed / frequency

                        = 1000 / 250

                        = 4 meters.

Hence, the wavelength(λ) of a 250 hz sound wave is 4 meters.

d. 4.92 x 106 m/s²
e. 8.12 × 104 m/s²

Answers

The acceleration of the satellite which is moving around the planet is

7.824 x 10²¹m/s².

Mass of a satellite of  moving around a planet = 2.15 x 10⁴kg

The  radius the planet  = 4.28 x 10⁷ m

The mass of the planet = 2.36 x 10²⁹kg

Gravitational constant = 6.67 x 10⁻¹¹ N (m/kg)

Acceleration of the satellite is calculated as :

[tex]a = \frac{G m}{R^2}[/tex]

where,

G = gravitational constant

m = mass of object

R = radius.

a = (6.67 x 10⁻¹¹ N(m/kg) x  2.15 x 10⁴kg )/( 4.28 x 10⁷ m)²

a = 7.824 x 10²¹m/s².

The acceleration of the satellite which is moving around the planet is

7.824 x 10²¹m/s².

It takes 14 minutes, or 840s, to drive to the Rockaway Mall from MOHS. If the Rockaway Mall is
11.3 miles, or 181,856m away from the school, calculate the average speed for this trip.

Answers

If it takes 14 minutes, or 840 seconds, to drive from MOHS to the Rockaway Mall, the average speed for this route is 216 m/s.

What's the average speed response?

The total distance something has traveled is divided by the total amount of time it took to traverse that distance to arrive at its average speed. Speed is the current rate of movement of something. Average speed is the speed that a vehicle travels at on average over the course of a trip.

Give an example of the typical speed.

The average speed is calculated by dividing the total distance traveled throughout the entire time period. A person's average speed, for instance, is calculated as 40 miles divided by 40 minutes, or 1 mile per minute, if it takes them 40 minutes to drive 20 miles north, 20 miles south, and then 20 miles in between (60 mph).

Semiconductor materials with band gaps greater than 3. 5 ev are considered to be a?.

Answers

Semiconductor materials are categorized as insulators if their band gaps are bigger than 3 and 5 eV.

An electron can easily move from the valence band to the conduction band in the presence of external thermal energy because semiconductor materials have low but finite band gap energies. The usual band gap energy range of semiconductor materials is 0.5eV–3eV.

Contrary to ordinary semiconductors like silicon, which have bandgaps in the range of 0.6 to 1.5 eV, wide-bandgap materials have bandgaps above 2 eV. In a p-type semiconductor, the majority of the carriers are holes, while the minority are electrons.

The advancement of communications, computing, healthcare, military systems, transportation, clean energy, and numerous more uses is made possible by semiconductors, which are a crucial part of electronic equipment.
