In space gravity supplies the centripetal force that causes satellites to orbit larger bodies. if you know the mass and altitude of a satellite in orbit around the Earth, you can calculate how quickly it needs to travel to maintain that orbit.

Question
Mrs. Adams class decides to try an experiment. She rubs a blown up balloon on Sandy's head. After this, she takes the balloon and places it on the side of the wall, where it sticks, instead of falling to the ground. Also, Sandy's hair is now sticking almost straight out. What causes Sandy's hair to act this way?
Solution 1
This would be static electricity when an object has a larger positive charge than the objects around it.
Solution 2

Answer: static electricity

Question
The gravitational force between two objects increase as the mass increases or distance decreases
Solution 1
The correct answer is: True

Explanation:
According to Newton's Gravitational law:

F_g = \frac{Gm_1m_2}{r^2}

As you can see the gravitational force is directly proportional to the masses of the objects while inversely proportional to the square of distance (r^2) between them.

Hence, yes, your statement is true!

Question
Sound waves travel at about 259 meters per second through gaseous carbon dioxide. They travel at about 1,162 meters per second through liquid ethanol. And they travel at 1,960 meters per second though solid lead. Which of the following statements about electromagnetic waves is true? A. Electromagnetic waves travel faster than sound waves through all media. B. Electromagnetic waves travel faster than sound waves through gases but not through liquids. C. Electromagnetic waves travel faster than sound waves through liquids but not through solids. D. Sound waves travel faster than electromagnetic waves through all media.
Solution 1
The correct answer is
A. Electromagnetic waves travel faster than sound waves through all media.

In fact, electromagnetic waves in vacuum travel at the speed of light:
c=3 \cdot 10^8 m/s
which is a huge value compared to the value of the speed of sound through all media listed in the problem. In a medium, the speed of the electromagnetic waves is slightly reduced compared to c, but still much greater than the value of the speed of sound.
Question

Question
A car came to a stop from a speed of 35 m/s in a time of 8.1 seconds. What was the acceleration of the car? A. -10.2 m/s B. -5.11 m/s C. -4.32 m/s D. -9.80 m/s
Solution 1

Answer:

The acceleration of the car is -4.32 m/s^2.

(C) is correct.

Explanation:

Given that,

Speed of car u= 35 m/s

Time t = 8.1 s

We need to calculate the acceleration

using equation of motion

v = u+at

Where, v = final velocity

u = initial velocity

t = time

a = acceleration

0=35+a\times8.1

a = -\dfrac{35}{8.1}

a = -4.32\ m/s^2

Hence, The acceleration of the car is -4.32 m/s^2.

Solution 2
Simply subtract the two velocities and divide by 8.1,

\frac{0 - 35}{8.1} = - 4.32
