5! 5! 5! 5! it's 5!!!!!!!!!! Well that's what my friend told me so
The applied force is different for the two cases
The case A with a greater force involves the greatest momentum change
The case A involves the greatest force.
<h3>What is collision?</h3>
- This is the head-on impact between two object moving in opposite or same direction.
The initial momentum of the two ball is the same.
P = mv
where;
- m is the mass of each
- v is the initial velocity of each ball
Since the force applied by the arm is different, the final velocity of the balls before stopping will be different.
Thus, the final momentum of each ball will be different
The impulse experienced by each ball is different since impulse is the change in momentum of the balls.
J = ΔP
The force applied by the rigid arm is greater than the force applied by the relaxed arm because the force applied by the rigid arm will cause the ball to be brought to rest faster.
Thus, we can conclude the following;
- The applied force is different for the two cases
- The case A with a greater force involves the greatest momentum change
- The case A involves the greatest force.

Answer:
The Gravitational Force between the 2 masses is approximately 1.209ｘ10^32 Newton’s
Explanation:
Answer:
n = 2.0686
Explanation:
When an unpolarized ray of light is reflected on a surface, the reflected ray is partially polarized, complete polarization occurs when it is true that between the transmitted and reflected ray one has 90, the relationship is
n = so tea
let's calculate
n = tan 64.2
n = 2.0686
Answer:
(a). The density of the object is 1382 kg/m³.
(b). The density of the oil is 536.4 kg/m³.
Explanation:
Given that,
Weight in air = 79.1 N
Weight in water = 21.8 N
Weight in oil = 48.4 N
We need to calculate the volume of object
Using formula of buoyant force
Put the value into the formula
We need to calculate the density
Using formula of buoyant force
The density of the object is 1382 kg/m³.
(b). We need to calculate the volume of object
Using formula of buoyant force
We need to calculate the density
Using formula of buoyant force
The density of the oil is 536.4 kg/m³.
Hence, This is the required solution.
