Answer:
Explanation:
A free-body diagram is a sketch of an object of interest with all the surrounding objects stripped away and all of the forces acting on the body shown. The drawing of a free-body diagram is an important step in the solving of mechanics problems since it helps to visualize all the forces acting on a single object. The net external force acting on the object must be obtained in order to apply Newton's Second Law to the motion of the object.
A free-body diagram or isolated-body diagram is useful in problems involving equilibrium of forces.
Free-body diagrams are useful for setting up standard mechanics problems.
Answer:
The new speed of the aircraft with respect to the ground is 1414.3 mph.
Explanation:
Given that,
Angle = 37°
Velocity of jet airliner = 693 mph
Velocity of wind = 798 mph
We know that,
The new velocity of the aircraft with respect to the ground

We need to calculate the new speed of the aircraft with respect to the ground
Using formula for velocity

Put the value into the formula


Hence, The new speed of the aircraft with respect to the ground is 1414.3 mph.
Answer A, low energy and long wavelength.
Two ways that strong nuclear and weak nuclear forces are alike: Strong nuclear and weak nuclear their alike because they deal with atoms and subatomic particles. ... Two ways that electromagnetic force and gravity are alike: Electromagnetic force and gravity are alike because both of them has an infinity force.
Answer:
137.2J
Explanation:
Ep= mgh
Given,
and we know, g = 9.81 N/kg
Ep= 2 × 9.81 × 7
Ep= 137.2J
