a = 5 m/^2
F = 5*12 = 60 Newtons
A 5.77 kg object is tied to the end of a cord and whirled in a horizontal circle of radius 355 cm. The object completes 4.4 revolutions every 6.94E-3 hours. What is the centripetal force exerted on the object?
The centripetal force exerted on the object is 25.24 N.
The given parameters:
mass of the object, m = 5.77 kgradius of the circle, r = 355 cm = 3.55 mnumber of revolutions, N = 4.4 rev for 6.9 x 10⁻³ hoursThe angular speed of the object is calculated as follows;
[tex]\omega = \frac{4.4 \ rev}{6.9 \times 10^{-3} \ h} \times \frac{1 \ h}{3600 \ s} \times \frac{2 \ \pi \ rad}{1 \ rev} = 1.11 \ rad/s[/tex]
The centripetal force exerted on the object is calculated as follows;
[tex]F =m \omega ^2 r\\\\F = 5.77 \times (1.11)^2 \times 3.55\\\\F = 25.24 \ N[/tex]
Thus, the centripetal force exerted on the object is 25.24 N.

A champion weight lifter raises a 240 kg barbell a distance of 2.1 m. How much potential energy has
the barbell gained?
Answer:
Your answer is below …….
Explanation:
25. Brutus, a champion weightlifter, raises
240 kg of weights a distance of 2.35 m.
a. How much work is done by Brutus
lifting the weights?
W=Fd=mgd
= (240 kg)(9.80 m/s2)(2.35 m)
= 5.5 x 103j
b. How much work is done by Brutus
holding the weights above his head?
d=0, so no work
c. How much work is done by Brutus
lowering them back to the ground?
d is opposite of motion in part a, so
W is also the opposite, -5.5 x 103 J.
d. Does Brutus do work if he lets go of
the weights and they fall back to the
ground?
No. He exerts no force, so he does
no work, positive or negative.
If Brutus completes the lift in 2.5 s.
how much power is developed?
* = multiply
[tex]P = \frac{W}{t} = \frac{5.53 * 10x^{3} J}{2.5s} = 2.2 kW[/tex]

Which of the following processes generated heat during earths formation that is still a source of heat in earths interior
Answer:
There are three main sources of heat in the deep earth: (1) heat from when the planet formed and accreted, which has not yet been lost; (2) frictional heating, caused by denser core material sinking to the center of the planet; and (3) heat from the decay of radioactive elementscalculate the density, in g/l, of sf6 gas at 27°c and 0.500 atm pressure.
The density of the SF₆ gas at the given pressure and temperature is 2.96 g/l.
The given parameters:
temperature of the SF₆ gas, T = 27 ⁰C = 273 + 27 = 300 Kpressure of the SF₆ gas, P = 0.5 atmThe molecular mass of the SF₆ gas is calculated as follows;
M of SF₆ = 32 + (6 x 19) = 146 g/mol
The density of the SF₆ gas is calculated by applying ideal gas law as follows;
[tex]PV = nRT\\\\PV = \frac{m}{M} RT\\\\PM = \frac{m}{V} RT\\\\PM = \rho RT\\\\\rho = \frac{PM}{RT}[/tex]
where;

Answer:
Conduction
Explanation:
Because when a molecule is transferred to another molecule then this in going into direct contact
For example if we have a pan and it is boiling well the heat that is on the pan holder that stays in place and it won`t move anywhere else like there is Radiation and Convection but for this question the answer would be Conduction
How do motors use energy? Do they convert electrical energy into mechanical energy OR mechanical energy into electrical energy?
Plz help asap!
Answer:
Motors convert electrical energy into mechanical energy
Explanation:
A motor uses electrical energy to create mechanical energy by creating magnetic fields causing the motor to spin. A generator is the opposite and converts mechanical into electrical by spinning a motor in a magnetic field.
An electric motor can transforms electrical energy into mechanical energy. Therefore, option (1) is correct.
How do motors convert energy?Energy can be described as the ability of an object to do work. Energy can also be transformed to work and the work done on an object can be stored in the form of energy.
The energy contained by the object because of its motion is called kinetic energy. The energy contained by an object due to its position is called its potential energy. Mechanical energy can be defined as the sum between the kinetic energy and potential energy of a body according to the law of conservation of energy.
An electric motor is a machine that receives energy from electricity as electrical energy and transforms it into mechanical energy. Therefore, when electric energy is supplied to an electric motor it converts electrical energy into mechanical energy.

Calculate the acceleration of the box. (Assume that there is no friction.)
Answer:
2.5m/s^2
Explanation:
Since there is no friction, the only force acting on the box is the applied force
We can now use the equation Fnet = ma
and we can rearrange for a
a = Fnet/m
now input the values
a = 50N/20kg

Se lanza un balón verticalmente hacia arriba con una velocidad de 72 km/h. ¿Qué altura recorrió dicho cuerpo después de 0.05 minutos? (g = 10m/s2)
Usando la información contenida en la pregunta, la distancia que recorre la bola hacia arriba es de 15 m.
Velocidad inicial = 20 m / s
Tiempo= 3 s
Aceleración por gravedad = 10 ms-2
Velocidad final = 0 m / s
Usando la ecuación;
h = u t - 1 / 2 g t 2
h = (20 × 3) - 1/2 × 10 × (3) ^ 2
h = 60 - 45
h = 15 m

Which colour of light is refracted more by a prsim green or blue.explain
Answer:
The light waves are refracted as they enter and leave the prism. The shorter the wavelength of the light, the more it is refracted. As a result, red light is refracted the least and violet light is refracted the most - causing the coloured light to spread out to form a spectrum.
Explanation:
hope this helps
Answer: Neither, its actually violet aka purple. This is because it has the shortest wavelength. This is also why red light is refracted the least because it has the longest wavelength.

The c-c sigma bond in acetylene is formed by the overlap of which two orbitals.
Answer:When carbon atom tends to form single bonds then its hybridization is , when carbon atom tends to form double bond then its hybridization is and when a carbon atom is attached to a triple bond or with two double bonds then its hydridization is sp.
For example, in HCN molecule there is a triple existing between the carbon and nitrogen atom.
So, hybridization of carbon in this molecules is sp. Moreover, nitrogen atom is also attached via triple bond and it also has a lone pair of electrons. Hence, the hybridization of nitrogen atom is also sp.
Thus, we can conclude that s and p type of orbitals overlap to form the sigma bond between C and N in H−C≡N:

Help plz????????? Giving out Brainly
Answer:
Answer should be (B)
Explanation:
If the forces on an object are balanced (or if there are no forces acting on it), this is what happens: a stationary object stays still. a moving object continues to move at the same speed and in the same direction.
ALSO: forces acting upon an object are balanced, then the object will maintain its state of motion. To maintain the state of motion is to keep the current speed and direction. But if the forces are not balanced, the object will change its state of motion.

A. The TV remote has a greater difference in electric potential energy
B. The car battery has more kinetic energy
C. The TV remote has more kinetic energy
D. The car battery has a greater difference in electric potential energy
A 12 volt car battery will produces more current than a 1.5 volt battery for a TV remote because the car battery has a greater difference in electric potential energy than a 1.5 Volt battery. The correct answer is D
The potential difference between any two point in a circuit is the work done when one coulomb of charge moves from one point to the other. Potential difference is a kind of electrical pressure difference between two point.
The difference in electric potential in a 12 Volt battery is greater than the difference in electric potential in a 1.5 Volt battery.
According to Ohm's law, Voltage supplied is proportional to current produced. That is, V = lR. Where R = resistance.
