The correct answer for the question that is being presented above is this one: "action force." Using a hammer to drive a nail, it is the reaction force that brings the motion of the hammer to a stop but the action force that drives the nail into the wood.
Explanation:
The reaction force is what presents you drive because it acts on you. Newton's Third Law of Motion describes that forces perpetually come in action-reaction pairs. The Third Law states that for every action force, there is an identical and opposite reaction force. The ball exerts an equal and opposite force on the bat.
Answer:
H_w = 2.129 m
Explanation:
given,
Width of the weir, B = 1.2 m
Depth of the upstream weir, y = 2.5 m
Discharge, Q = 0.5 m³/s
Weir coefficient, C_w = 1.84 m
Now, calculating the water head over the weir
now, level of weir on the channel
H_w = y - H
H_w = 2.5 - 0.371
H_w = 2.129 m
Height at which weir should place is equal to 2.129 m.
The answer is 6 and a half days
Answer:
physics is the study of functions, systems and and the explainable reasons why they do what they do.
To solve this problem we will apply the concepts related to kinetic energy and the value of momentum. Both variables are dependent on the mass and velocity of the object. By dividing between the two terms we can clear the speed of the object and find its value. Let's proceed to define the kinetic energy, for which,
Here,
m = mass
v = Velocity
The expression of momentum of a object is given as
If we divide two expression we have that
Rearrange to find the velocity we have that
Replacing we have that
Therefore the speed of the object is 23.68m/s
