IF EARTH HAD NO ATMOSPHERE, WOULD A FALLING OBJECT EVER REACH TERMIONAL VELOCITY?
EleoNora [17]
No.  What most people call 'terminal velocity' is the speed of the falling
object when the downward force of gravity is equal to the upward force
of air resistance.  At that speed, the vertical forces on the object are
balanced, so it stops accelerating, and falls at a constant speed.

If there were no atmosphere, there would be no upward force due to
air resistance.  The falling object would continue to accelerate all the
way down until it went 'splat'.

This is exactly the situation for meteoroids or asteroids falling onto the Moon.

When resistance force is increased on a lever which of the following happens to the effort force?
Sauron [17]
When resistance force on a lever increases, nothing happens automatically. 
But if you want to keep lifting the load, then YOU must increase the force of
your effort in order to make it happen.

A tennis ball bounces on the floor three times. If each time it loses 11% of its energy due to heating, how high does it rise af
aalyn [17]

Answer:

h = 3.10 m

Explanation:

As we know that after each bounce it will lose its 11% of energy

So remaining energy after each bounce is 89%

so let say its initial energy is E

so after first bounce the energy is

E_1 = 0.89 E

after 2nd bounce the energy is

E_2 = 0.89(0.89 E)

After third bounce the energy is

E_3 = (0.89)(0.89)(0.89)E

here initial energy is given as

E = mgH_o

now let say final height is "h" so after third bounce the energy is given as

E_3 = mgh

now from above equation we have

mgh = (0.89)(0.89)(0.89)(mgH)

h = 0.705H

h = 0.705(4.4 m)

h = 3.10 m

Question number 11 how did we found the answer ?
BaLLatris [955]

Answer:

Option A. 57.14 Ω

Explanation:

From the question given above, the following data were obtained:

Resistor 1 (R₁) = 100 Ω

Resistor 2 (R₂) = 400 Ω

Resistor 3 (R₃) = 200 Ω

Equivalent Resistor (Rₚ) =?

The equivalent resistor in the above circuit can be obtained as follow:

1/Rₚ = 1/R₁ + 1/R₂ + 1/R₃

1/Rₚ = 1/100 + 1/400 + 1/200

Find the least common multiple (lcm) of 100, 400 and 200. The result is 400. Divide 400 by 100, 200 and 400 respectively and multiply the result with the numerator as shown

1/Rₚ = (4 + 1 + 2)/400

1/Rₚ = 7/400

Invert

Rₚ = 400/7

Rₚ = 57.14 Ω
