A wave breaks due to the interference of the ocean floor with its oscillatory motion. As the wave nears the shore and the water gets shallower, the bottom of the wave slows down while the top continues its original speed, causing the wave to break.
A wave will 'break' or crash due to its interaction with the ocean floor as it approaches the shore. Waves follow an oscillatory motion, moving in an up-down pattern. When a wave gets closer to shore, the water becomes shallower which interferes with the oscillatory motion of the wave. The bottom of the wave slows down upon hitting the ocean floor while the top of the wave continues its original speed. This causes the wave to become steep and eventually break, forming the crashing wave front we often see on beaches.

Answer:
The change in momentum increases because the impact time increases.
Explanation:
The change in momentum of an object is also called impulse (J), and it is equal to
where
F is the force applied to the object
is the time taken for the change in momentum of the object to occur (the impact time)
From the formula above, we can notice that:
- the larger the force, the larger the change in momentum
- the larger the impact time, the larger the change in momentum
In the example of the baseball caught by the glove, when the glove moves backward, the time taken for the ball to stop increases (due to the movement of the gloves). Looking at the formula, we see that this means that the impulse (the change in momentum) increases.
Answer:
The change in momentum stays the same because the ball still comes to a stop.
Explanation:
here we know that momentum is defined as the product of mass and velocity
so here we know that
now we know that formula to find the change in momentum is given as
now when player moves his hand backwards then in this case final speed of the ball is zero and initial speed is same
So here we can say that there is no change in the equation but only the the to stop the ball is increased.
So here change in momentum will remain the same
a. Its magnitude increased and its direction changed.
b. Its magnitude increased but its direction remained the same.
c. Its magnitude remained the same but its direction changed.
d. Its magnitude and its direction both remained the same.
The correct statement should be "Its magnitude remained the same but its direction changed". Option C is correct.
Given information:
A rubber ball moving at a speed of 5 m/s hit a flat wall and returned to the thrower at 5 m/s.
Now, the mass of the ball doesn't change and the magnitude of the velocity is also the same.
Momentum can be defined as the product of mass and velocity. It is a vector quantity because velocity is also a vector quantity, and it has magnitude and direction.
Now, the magnitude of momentum will be the same because mass and velocity don't change in magnitude.
The direction of velocity will be reversed. So, the direction of momentum will also be reversed.
Therefore, the correct statement should be "Its magnitude remained the same but its direction changed". Option C is correct.

Answer:
d. Its magnitude and its direction both remained the same.
Explanation:
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
The law of conservation of momentum states that the total linear momentum of any closed system would always remain constant with respect to time.
This ultimately implies that, the law of conservation of momentum states that if objects exert forces only on each other, their total momentum is conserved.
In this scenario, a rubber ball moving at a speed of 5 m/s hit a flat wall and returned to the thrower at 5 m/s. Thus, the statement which correctly describes the momentum of the rubber ball is that its magnitude and its direction both remained the same because its velocity didn't change while returning to the thrower.
Answer:
M=f/a
Explanation:
F=m x a
÷a both sides
F÷a = m
M=f/a
Answer:
Explanation:
Tarzan swing can be thought of as change in potential energy by going from higher location We solve for height of beginning of the swing by using simple cosine equation:
So
ΔE=mg(h₂-h₁)
The potential energy of Tarzan initial position is converted into kinetic energy of his swing.By using kinetic equation
(1) 3.40 × 10^2 s (3) 9.73 × 10^−1 s
(2) 1.02 × 10^0 s (4) 2.94 × 10^−3 s
Answer:
Battery stores the electrical energy in the chemical form. When we connect it's positive and negative terminals and provide the path for the flow of electrons then it converts that chemical energy into the electrical energy and hence the direct current is created. So both of the technicians are right.
