The angle of incidence equals the angle of reflection. When a ray of light strikes a pane of window glass at a perpendicular angle, it passes through the glass and exits at a perpendicular angle on the other side.
However, if the ray of light strikes the glass at an angle, it is reflected off the surface of the glass at the same angle.The angle of incidence (angle at which a ray of light strikes a pane of window glass) is equal to the angle of refraction (angle at which it passes out the other side).
This is because when light hits a surface at an angle, it bounces off at the same angle. The angle of incidence is the angle between the ray of light and the perpendicular to the surface. The angle of refraction is the angle between the ray of light and the perpendicular to the surface.

A passenger on a ferris wheel moves in a vertical circle at constant speed. Are the forces on her balanced?.
In order to prevent the Ferris wheel from accelerate, the forces must be balanced. Newton's first law of motion states that unless an unbalanced force acts upon a body.
it will remain in its state of rest or uniform motion. The Ferris wheel moves at a consistent speed in a vertical circle, as stated in the question. Unbalanced force is what happens when two forces operating in opposition to one another on a body are not of the same size and magnitude and accelerate.
Keep in mind that the constant speed implies that the forces are in balance, as the Ferris wheel would accelerate under an unbalanced force.

The net force acting on the airplane is 25N.
Forces acting on the paper airplane when it is in the air:
The forward force generated by the engine, propeller, or rotor is called thrust. It resists or defeats the drag force. It operates generally perpendicular to the longitudinal axis. However, as will be discussed later, this is not always the case.Drag is an airflow disruption generated by the wing, rotor, fuselage, and other projecting surfaces that causes a backward, decelerating force. Drag acts backward and perpendicular to the relative wind, opposing thrust.Weight is the total load carried by airplane, including the weight of the crew, fuel, and any cargo or baggage. Due to the influence of gravity, weight pulls the airplane downward.Lift—acts perpendicular to the flight path through the center of lift and opposes the weight's downward force. It is produced by the air's dynamic influence on the airfoil.Given.
Weight of the paper airplane, F1 = 16N
The force of air resistance, F2 = 9N
Net force = F1 + F2
Net force = 25N

Compared to the initial velocity, the velocity of the ball at the maximum height is zero m/s.
What is motion under gravity?We know that in the gravitational field, there is a force that acts to either accelerate or decelerate a body. If the body is accelerated, then the object must be moving in the same direction as gravity, that is, the object is moving downwards.
If the object is decelerated then the object is moving in a direction that is opposite to gravity, then the motion of the object must be slowed down continuously until the object is gradually brought to a stop.
When we through a ball upwards at a given speed, the speed of the ball would continue to decrease until the ball would eventually attain a minimum speed of zero at the maximum height.

When a spring is only pulled by Bob with 200 N force, the spring stretches 20 cm. If the same spring is pulled by Bob and Carlos with 200 N forces each, the string will stretch 40 cm.
The elasticity is followed the Hooke's Law:

From the Hooke's Law, we know that the applied force is directly proportional to the change of length, or
F2 : F1 = x2 : x1
Parameters given in the problem:
F1 = 200 N (Force applied by Bob)
x1 = 20 cm
F2 = 200 + 200 = 400 N (Forces applied aby Bob and Carlos)
Therefore,

The magnitude of a single extra force necessary to keep the rod in its mechanical equilibrium is 20N in the same direction with the 5.0kg blocks' weight force.
A system is in the mechanical equilibrium when it is at rest and the resultant of the force working on the system is equal to zero (0) or no movement happen within the system.
Please take a look at the drawing below.
The existance of 2 blocks attached to each of the rod's ends are enable the rod to move in a circular form. Hence, we could conclude that both of the blocks are giving centripetal forces to the rod.
Centripetal force is the force that works in a system and make a system to move within the curved path. The direction of this force is always perpendicular to the system fixed center point.
On the case, the center point is the center of gravity of rod, where the weight force (W) working in the system. Assuming that the rod is a symetrical solid rod, hence the center point is exatcly at the middle of the rod.
Both of the blocks are giving weight forces to the system with their mass. However since they are differences on their mass, their weight forces are also working differently.
Both of the blocks are working to the system and moving the system into their respective direction, which are the opposite of each other.
Hence, we could conclude that we need to give extra force into one of the block's force direction to balance all the forces working in the system.
Because we want the system to be in its mechanical equilibrium, we have to use the First Law of Newton where the force resultant of the system must be equal to zero (0).
We could write the equation for this system:
∑F = 0
Fs1 - Fs2 + Fs3= 0
(W1 × 1) - (W2 × 1) + (F3 × 1) = 0
(7×10×1) - (5×10×1) + F3 =0
70 - 50 + F3 = 0
F3 = - 20N

With a doubling of tangential velocity, this formula predicts that the centripetal force will also double.
