Answer:
v2 = 2.36 m/s
Explanation:
Momentum is simply the the product of mass of an object and it velocity. Generally, when object moves they have momentum . The unit for momentum is kgm/s.
During collision momentum is conserved . This means that
initial momentum = final momentum
If their is an equal and opposite reaction your momentum should be equal to your BFF.
m1 v1 = m2 v2
m1 = 65 kg
v1 = 2.0 m/s
m2 = 55 kg
v2 = ?
m1 v1 = m2 v2
65 × 2 = 55v2
130 = 55 v2
divide both sides by 55
v2 = 130/55
v2 = 2.36363636364
v2 = 2.36 m/s

Answer:
0.407 c
Explanation:
L₀ = Actual length of the spaceship lilac = 717 m
L = length of spaceship observed = 655 m
v = speed of lilac relative to earth
Using the equation
Inserting the values
v = 0.407 c
Answer:
The polarity of electromagnet also gets reversed when the direction of current is reversed. The current flows from negative terminal to positive terminal in an electromagnet due to the flow of electrons so polarity is also established in the electromagnet. As, the current direction is reversed, the polarity of magnet also gets reversed because the polarity of magnet depends on the direction of the current.
