You jump off a truck and accelerate toward the surface of the Earth. Does the Earth accelerate toward you?
Triss [41]

When we jump from the truck and accelerate towards the earth surface, the earth also accelerates towards us but it's acceleration is very negligible.

To find the answer, we need to know about the acceleration of earth due to the gravitational attraction.

<h3>What's the gravitational force between the earth and a person?</h3>
  • Gravitational attraction force is GMm/r² between the earth and a person.
  • M= mass of the earth

m= mass of the person

r= separation between them.

<h3>What's the acceleration of the earth towards the person when he jumps from a truck?</h3>
  • According to Newton's second law, Force = M×acceleration
  • Acceleration= Force / M
  • Here, Force = GMm/r²,

so acceleration of earth= Gm/r²

  • As this acceleration is very small, so we can't notice it.

Thus, we can conclude that the earth also accelerates towards us.

Two oppositely charged parallel sheets of charge give rise to a field of 9.00×1011 N/C between them. The sheets are square and h
Maksim231197 [3]

Answer:

Q = 5.75 C

Explanation:

As we know that due to a thin sheet electric field at a point near its surface is given as

E = \frac{\sigma}{2\epsilon_0}

now we have two sheets of opposite charges so the net electric field is double that of field due to one sheet

so we have

E_{net} = 2E

E_{net} = \frac{\sigma}{\epsilon_0}

9.00 \times 10^{11} = \frac{Q}{A\epsilon_0}

now we have

Q = 9.00 \times 10^{11}(0.85 \times 0.85)(8.85 \times 10^{-12})

Q = 5.75 C

A downhill skier was able to move 560 meters in 25 seconds. What is the skier’s average speed? (Round your answer to the nearest
slava [35]
Speed is distance in a specific time period. When someone ask use the unit "m/s" this period of time is one second. If the skier was able to move 560 m in 25 seconds, in one second how much distance he moves? That is the question.
You can solve this problem like
560m/25s = 22,4 m/s
Good luck!
