The magnitude of applied force on the car by Mike is 50 N.
Given data:
The mass of car is, m = 1000 kg.
The magnitude of acceleration of car is, .
According to Newton's second law of motion, the force applied on the object is expressed as the product of mass of object and magnitude of acceleration caused by the applied force on the object.
Therefore,
Here, F is magnitude of applied force on car.
Solving as,
Thus, we can conclude that Mike is applying 50 N of force on his car.

Answer:
The answer to your question is: F = 50 N
Explanation:
Data
mass = 1000 kg
acceleration = 0.05m/s2
F = ?
Formula
F = m x a
Substitution
F = 1000 kg x 0.05 m/s2 = 50 kgm/s2 = 50 N
Mike is applying a force of 50 N to the car.
Answer:
Static Friction is acting upon the book
Answer:
The particle will be rendered still
Explanation:
The particle will be rendered still because of the Newton’s 1st law of motion states that a body will continue to move on forever until contacted by an equal and opposite force. The same case has been produced here and it is justifying the law. If the Force has another direction and magnitude than 10 N then the body will continue to move on in the direction of the greater force.
B. A molecule moves in the same direction as a wave.
C. The vibration results in a molecule moving vertically.
D. The vibration of the point in the medium ends.
The scenario that would cause a sound to stop being produced is when a molecule moves through its normal position to the opposite side of its normal position. The answer is letter A. This is also known as destructive interference.
A.) a 30-watt CD player used for 3 hours (10,800 seconds)
B.) a 300-watt blender used for 2 minutes (120 seconds)
C.) a 1,500-watt hair dryer used for 3 minutes (180 seconds)
D.) a 200-watt computer used for 10 hours ( 36,000 seconds)
Answer:
a 200-watt computer used for 10 hours ( 36,000 seconds)
Explanation:
A. the less massive object had gained momentum.
B. the more massive object had gained momentum.
C. both objects had the same momentum.
D. both objects lost momentum.
The more massive object will lose momentum after collision while the less massive object will gain momentum after collision.
Apply theprinciple of conservation of linear momentum for elastic collision;
let the heavier object = m₁
m₁u + m₂(-u) = m₁(-v₁) + m₂v₂
m₁u - m₂u = -m₁v₁ + m₂v₂
where;
m₁u and m₂u are initial momentum of both objects before collision
m₁v₁ and m₂v₂ are final momentum of both objects after collision
Thus, from the equation above we can conclude the following, the more massive object will lose momentum after collision while the less massive object will gain momentum after collision.

Answer:A
Explanation:
Given
mass of two objects are and
taking
Suppose and are the velocities of and
and
therefore after elastic collision velocity of and and

The height of more than 50 m then the average power output of Niagara Falls will be equal to 426.9 MW.
Power can be defined as the amount of workcompleted in a given amount of time. Watt (W), which is derived from joules per second (J/s), is the SI unit of power. Horsepower (hp), which is roughly equivalent to 745.7 watts, is a unit of measurement sometimes used to describe the power of motor vehicles and other devices.
Average power is calculated by dividing the total energy used by the total time required. The average quantity of work completed or energy converted per unit of time is known as average power.
The change in potential energy of the falls mostly determines its power output:
Q = -ΔP = -(P2 - P1)
Use the equation of Potential energy:
P = mgh
If we take the base of the falls as the reference height, the height at point 1 is 52 meters, and at point 2 h=0, P2=0,
Q = P1 = mgh
The rate of change in potential energy over time can be calculated by substituting the mass rate M for m. As a result, the power produced:
W = mgh
W = 2.8 × 10³ × 1 × 10³ × 9.8 × 52
W = 1426.9 MW.

Answer:
Power output: W=1426.9MW
Explanation:
The power output of the falls is given mainly by its change in potential energy:
The potential energy for any point can be calculated as:
If we consider the base of the falls to be the reference height, at point 2 h=0, so P2=0, and height at point 1 equals 52m:
If we replace m with the mass rate M we obtain the rate of change in potential energy over time, so the power generated:
