A rocket is launching upwards. The force acting on the rocket to move upward is F. The forces acting opposite to thrust are weight and drag force. The drag force is due to the air resistance. In order to move upwards the thrust force must be greater than weight and drag force. Figure shows the free body diagram of rocket at the time of launching.There are only three forces: weight (always present), thrust (provided from the rocket’s engines to lift it up) and air resistance (said specifically to be not negligible). There are no horizontal forces.

Can some one answer 4 for me and if u can't read it it says what can scientists learn by studying layers of rock in the Earth
ella [17]
They can learn more about Earth's history and environment. Studying rocks can also help scientists discover clues about what Earth was like millions of years ago. That can help them comprehend on our effects on the environment and its probable effects on humans.

Calculate the tension on the rope.<br> A. 57.89 N<br> B. 32.73 N<br> C. 69.84 N<br> D. 12.55 N
Ratling [72]

Hi there!

\large\boxed{\text{B. 32.73N}}

To calculate the tension, we must calculate the acceleration of the system.

Begin with a summation of forces:

∑F = -M₁gsinФ + T - T + M₂g

Simplify and solve for acceleration: (Tensions cancel out)

a = \frac{-M_1gsin\theta + T - T + M_2g}{M_1+M_2}

Plug in values. Let g = 10 m/s²

a = \frac{-3(10)(sin30)+8(10)}{3+8} = 5.91 m/s^{2}

Now, to find tension, let's sum up the forces acting on ONE block. For simplicity, we can look at the hanging block:

∑F = -T + W

ma = -T + W

Rearrange to solve for T:

T = W - ma

We know the acceleration, so plug in the values:

T = (8)(10) - (8)(5.91) = 32.73 N
