Answer:
v = 5.88 10⁷ m / s
Explanation:
For this exercise we use the relation
E = m c²
also indicate that all energy is converted into kinetic energy
E = K = ½ (M-2m) v²
where m is the mass of antimatter and M is the mass of the ship's mass. Factor two is due to the fact that equal amounts of matter and antimatter must be combined
we substitute
m c² = ½ (M-2m) v²
v² =
let's calculate
v =
v =
v = 5.88 10⁷ m / s
Answer:
(D) 3
Explanation:
The angular momentum is given by:
Thus, the magnitude of the angular momenta of both solar systems are given by:
where we have taken that both systems has the same radius.
By taking into account that T1=3T2, we have
but L1=L2=L:
Hence, the answer is (D) 3

Answer:
Part a)
Part b)
Part c)
Part d)
Explanation:
Part a)
For hanger we know that it will have tension force upwards while it has downwards its weight so we will have
so we have
Part b)
now for car that is rolling on the floor the net force is given as
Part c)
now we know that the cart and the hanger both are connected to each other
so they must have same acceleration
so we will have
Part d)
now we know that
M = 2.40 kg
m = 0.50 kg
so we will have
