Answer:
Christian
Explanation:
Given that
Force applied by Sean ,F₁=100 N
Force applied by Christian ,F₂=200 N
Lets take mass of the box = m kg
As we know that from second law of Newton's
F= m a
F=Force,m=mass ,a=acceleration






From the above we can say that acceleration a₂ is greater than a₁ is for the same mass of the box.
Therefore Christian will acceleration more for the box.
The mass of the person would be 66 kg on both Earth and the Moon.
Answer:

Explanation:
The rate of volume flow out of tank can be expressed as:

where,
dV/dt = Volume flow rate
A = Cross-sectional area of outlet = πd²/4
d = diameter of circular outlet
dL = Displacement covered by water
dt = time taken
but we know that:
Velocity = υ = displacement/time = dL/dt
Substituting the values of "dL/dt" and "A" in the equation, we get:

This is the expression for volume flow rate dV/dt, on terms pf v, d.
Answer:
In one rotation, the large wheel turns 4m.
Explanation:
The given values are:
Input distance,
= 0.64 m
Mechanical advantage,
= 0.16
As we know,
⇒ 
On putting the values, we get
⇒ 
⇒
Since momentum is a vector quantity, take any direction as positive and other as negative. Answer won't change.
