Answer:
the Force is the one created by the engines, W is the weight of the rocket and its fuel and fr is the friction force created by the air
Explanation:
Unfortunately you did not include a diagram with the point where to make the drawing, let's assume that the point is the initial launch point, just leaving the ramp.
In the attached we can see the forces on the rocket, the Force is the one created by the engines, W is the weight of the rocket and its fuel and fr is the friction force created by the air, which depends on several factors, the shape of the rocket, velocity, and air density with height
Answer:
It is necessary to search for new sources of energy because the sources we have now are non-renewable and exhaustible. The usage of these sources are increasing day by day and if this continues then one day we wlii be left with none so it is necessary to search for new sources of energy

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
