Answer:
<em>The change in momentum of the car is 3575 Kg.m/s</em>
Explanation:
<u>Impulse and Momentum</u>
The impulse (J) experienced by the object equals the change in momentum of the object (Δp).
The formula that represents the above statement is:
J = Δp
The impulse is calculated as
J = F.t
Where F is the applied force and t is the time.
The car hits a wall with a force of F=6500 N and stops in 0.55 s. Thus, the impulse is:
J = 6500 * 0.55
J = 3575 Kg.m/s
The change in momentum of the car is:
The change in momentum of the car is 3575 Kg.m/s
Answer:
Explanation:
given,
Radius of earth = 6400 Km
speed of a physics student in Miami, Florida, at latitude 26° = v
time period of rotation = 24 hour = 24 × 3600
= 86400 s
distance = speed × time
hence, the velocity of the student is equal to
2/1 i think because if you start with the example of 4 then from air to water makes it 3 and then to glass makes it 2. Therefore you decrease from 4 to 2 which breaks down in the ratio 2:1
The correct answer is physical weathering, also known as mechanical weathering. An example of this would be when water falls into the cracks of a rock. It freezes during cold times and expands in size, which causes the rock to crack even more. When it melts, the crack is bigger and new water goes inside and cracks it even more, and so on and so forth.
