<h3><u>Answer;</u></h3>
M.A = 4.25
<h3><u>Explanation;</u></h3>
Mechanical advantage is the ratio of the force required to do something in comparison to the actual force required using a simple machine.
It is the ratio of output force to the input force.
M.A = Output Force/ Input Force
Out put force 85 Kg = 850 N
Input force = 200 N
Therefore;
M.A = 850 N/200 N
= 4.25
The object particle move faster.
Explanation:
it holds protons and neutrons together
Answer:
one-third of its weight on Earth's surface
Explanation:
Weight of an object is = W = m*g
Gravity on Earth = g₁ = 9.8 m/s
Gravity on Mars = g₂ =
g₁
Weight of probe on earth = w₁ = m * g₁
Weight of probe on Mars = w₂ = m * g₂ -------- ( 1 )
As g₂ = g₁/3 --------- ( 2 )
Put equation (2) in equation (1)
so
Weight of probe on Mars = w₂ = m * g₁ /3
Weight of probe on Mars =
m * g₁ =
w₁
⇒Weight of probe on Mars =
Weight of probe on earth
