Answer:
3.7 m/s^2
Explanation:
The period of a simple pendulum is given by:

where L is the length of the pendulum and g is the free-fall acceleration on the planet.
Calling L the length of the pendulum, we know that:
is the period of the pendulum on Earth, and
is the free-fall acceleration on Earth
is the period of the pendulum on Mars, and
is the free-fall acceleration on Mars
Dividing the two expressions we get

And re-arranging it we can find the value of the free-fall acceleration on Mars:

Answer:
D. Nothing will happen; the seesaw will still be balanced.
Explanation:
D. Nothing will happen; the seesaw will still be balanced. Since both toruqes or momentums respect to the center have changed in the same amount (one-half their original distance) the seesaw will remain balanced, if the children change distance in a different amount then it will be out of balance
The output force is
<em>F = (input force) x (3.14) / (area of the </em><u><em>small</em></u><em> cylinder's piston)</em>
