<span>there is no horizontal displacement if he went straight up
straight up means vertical, so his vertical displacment is 20 m</span>
Answer:
Why do insects fly so high?
Because the angle of attack is so high, a lot of momentum is transferred downward into the flow. These two features create a large amount of lift force as well as some additional drag. The important feature, however, is the lift.
Why an Aeroplane flying has kinetic
A flying aeroplane has potential energy has it flies above the ground level. And since the aeroplane is flying motion is associated with it and thus possesses kinetic energy. Hence a flying aeroplane has both potential and kinetic energ
Explanation:
Convection, the matter is traveling in convection currents
Both carts experience the same force but Cart A has a greater speed after the recoil.
The given parameters;
- <em>Mass of the cart A = 0.4 kg</em>
- <em>Mass of the cart B = 0.8 kg</em>
Apply the principle of conservation of linear momentum to determine the velocity of the carts after collision;
According to Newton's third law of motion, action and reaction are equal and opposite. The force exerted on cart A is equal to the force exerted on cart B but in opposite direction.
Thus, the correct statement that compares the motion and forces acting on the two carts is "Both carts experience the same force but Cart A has a greater speed after the recoil."

The volume of the jet fuel is 1.213 x 10⁵ cm³.
<h3>What is density?</h3>
Density is a physical property that measures the ratio of mass to volume occupied by an object.
Density = mass/volume
Volume = mass/density
<h3> Volume of the jet fuel</h3>
The volume of the jet fuel is calculated as follows;
Volume = (97500 g)/(0.804 g/cm³)
Volume = 1.213 x 10⁵ cm³
Thus, the volume of the jet fuel is 1.213 x 10⁵ cm³.
