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

Complete Question
The complete question is shown on the first uploaded image
Answer:
a) 58 Hz b) 7.73 mV
Explanation:
From the complete question we are given that
Radius of the semi circle , a = 3.0 cm = (3.0)(1 × m/1 cm)
=3.0 × m
Angular speed ,w = 58 rev/s
= (58 rev/s)(2π rad /1 rev)
= 364.4 rad/s
Magnetic field, B = 15 mT
= (15 mT)(1 × T/ 1 mT)
= 15 × T
a) f = 58 rev/s
= 58 Hz
b) The Induced emf, ∈ = ω<em>Bπ</em> /2
= T)(π)(3.0 × m)^2)÷2[/tex]
= 0.007728 V
= 7.73 mV
Answer:
Once the fridge is moving you are still applying the same push force but now the opposing friction (now kinetic) force is less.
