what prevents the planets in our solar system from floating away?
A. Earth's gravitational pull
B. planets gravitational pull on one another
C. moon's gravitational pull
D. suns gravitational pull​

Answers

Answer 1
The suns gravity keeps planets in their orbits. There is no other force in space to pull them out of their orbits therefore they stay.
Answer 2

Suns' gravitational pull​ prevents the planets in our solar system from floating away, therefore the correct answer is option D.

What is a solar system?

It is a structure in which the sun's attractive force causes all the planetary systems and celestial bodies to revolve around this.

The Sun is believed to be located in the system's center in the sun-centered concept upon which our Solar System is founded.

The primary factor that causes the planets in the solar system to revolve around the sun is gravity.

                                         

The sun's pull of gravity prohibits the planets in our planetary system from moving away, hence option D is the appropriate

Answers

A black hole forms as a star collapses when it ceases emitting radiation from fusion reactions. This occurs after the star has consumed hydrogen, helium, then through iron.

Star evolution refers to the process by which stars evolve (change) over time.

A black hole can be defined as a collapsed star where the gravitational field in its nucleus becomes greater than particles cannot escape from it.

In consequence, black holes are cosmic bodies in which gravity is so powerful that nothing (i.e., particles, radiation, light, etc.) can escape from them.

Nuclear fusion refers to the energy reactions produced by the fusion of hydrogen at the core of a star, thereby becoming helium.

car was moving in a straight road of length 320 km it covered 240 km with an average velocity 75 km/hr then it ran out of fuel and stopped for 0.6 hr until it was refueled and completed its journey with a velocity 100 km/hr so the average velocity during the whole journey

Answers

The average velocity of the car for the whole journey is 69.57 km/h.

The given parameters:

Length of the road, L = 320 kmDistance covered = 240 km at 75 km/htime spent refueling, t₂ = 0.6 hrFinal velocity, = 100 km/hr

The time spent by the before refueling is calculated as follows;

[tex]t = \frac{d}{v} \\\\t_1 = \frac{240}{75} \\\\t_1 = 3.2 \ hours[/tex]

The time spent by the car for the remaining journey;

[tex]t_3 = \frac{320 - 240}{100} \\\\t_3 = 0.8 \ hr[/tex]

[tex]t = t_1 + t_2 + t_3\\\\t = 3.2 \ hr \ + \ 0.6 \ hr \ + \ 0.8 \ hr\\\\t = 4.6 \ hours[/tex]

The average velocity of the car for the whole journey is calculated as follows;

Use what you know about mass and how you use it to calculate force in the following situation. If each washer has a mass of 4. 9 g, then the mass of two washers in kilograms would be. Given that F = ma, and if 4 washers are attached to the string and car instead of 2, then the applied force on the car will be. Recall a = 10 m/s2.

Answers

Considering the change of units and the definition of weight, the mass of two washers would be 0.0098 kg and if 4 washers are attached to the string, then the applied force on the car will be 0.196 N.

Mass of two washers

If each washer has a mass of 4.9 g, then the mass of two washers will be calculated simply by multiplying the mass of 1 washer by the amount you have of them, in this case 2:

4.9 g×2= 9.8 g

Being 1 kg = 1000 g, you apply the following rule of three to make the change of units: if 1000 g equals 1 kg, 9.8 g equals how many kilograms?

[tex]mass=\frac{9.8 gramsx1 kg}{1000g}[/tex]

Solving:

mass= 0.0098 kg

Finally, the mass of two washers would be 0.0098 kg.

Applied force

On the other side, mass is the amount of matter that a body contains and weight is the action exerted by the force of gravity on the body.

The mass of an object will always be the same, no matter where it is located. Instead, the weight of the object will vary according to the force of gravity acting on it.

Weight is calculated as the product of the object's mass and the value of the gravitational acceleration:

W= m×g

In this case, you know:  

m= 4.9 g×4= 19.6 g= 0.0196 kg → the mass of 4 washers in kilogramsg= 10 m/s²

Replacing:

W= 0.0196 kg× 10 m/s²

Solving:

W= 0.196 N

Finally, if 4 washers are attached to the string, then the applied force on the car will be 0.196 N.

Question 5. One 1,5V battery runs a portable MP3 player that draws 5,7mA of current
for about six hours before it runs out.
a) What is the resistance If the portable MP3 player?
b) How much power is dissipated in the portable MP3 player?
c) Find the energy delivered by the portable MP3 player?

Answers

First, convert the values of the units to S.I units (otherwise the final answer may be wrong):

P.D = 1.5 volts
Current = 5.7 x 10^-3 amps
Time = 21600 seconds


a) To find resistance, you can use the equation V=IR and rearrange it to find the resistance.

Resistance = p.d / current
Resistance = 1.5 / 5.7x10^-3

Resistance = 263.2 ohms (rounded to 1dp)


b) To find power, you can use the following equations to calculate power:
P=VI
P=I^2 R
P = V^2 / R
P = E/T

You can use any of the equations and still get the right answer, however it's best to use the equations which have the values that you already know from the questions.

I used P=VI:

Power = p.d x current
Power = 1.5 x (5.7x^-3)

Power = 8.55 x 10^-3


c) To find energy, you can use the equation E=PT.

Energy = power x time

(Using the value of power from the previous question)

Energy = (8.55x10^-3) x 21600

Energy = 184.68 joules

The two chemical compounds having a molar ratio of 1 : 1 is CO₂ and K₂CO₃

                4       :    2         :   2       :       3

From the balanced equation above, the coefficients are 4, 2, 2, 3

A careful observation of the equation shows that CO₂ and K₂CO₃ exist in ratio 2 : 2 which can be simplified as 1 : 1

Therefore, we can conclude that CO₂ and K₂CO₃ has molar ratio of 1 : 1

Answers

Other than temperature, the property that also has an effect on the rates of chemical reactions is the concentration of the reactants. The correct answer is B

The rate of chemical reaction means how chemical react with respect to time or as a function of time. The rate of chemical reaction tells us the speed or how fast chemicals react.

There are many factors that can affect the rate of chemical reaction. Temperature is one of them. Increase in temperature will increase the rate at which chemical react.

The color of reactants, solubility of reactants and volume of reactants have nothing to do with the rate of chemical reaction.

Other than temperature, the property that also has an effect on the rates of chemical reactions is the concentration of the reactants.

Other factors affecting the rate of chemical reaction are:

Explanation:

Using the formula v² = u ² - 2gh

v = 0(final velocity is zero at maximum height), u = ?, g = 9.81m/s², h = 1.5m

0² = u² - 2×9.81×1.5

The plot appears to be telling you the force required to get the yellow block moving along the table. If one applies less than 3.0 N of force, the block remains motionless. But as soon as it starts to slide, one need only apply 1.5 N of force to keep it moving (presumably at a constant speed).
