-- Momentum is (mass) x (speed).
Object B has 1.5 times as much momentum as Object A has.
-- Kinetic energy is (1/2) x (mass) x (speed) .
Object B has 1.5 times as much kinetic energy as Object A has.
-- If they would both stop long enough to get on the scale,
Object B would weigh 1.5 times as much as Object A does.
Answer:
(a) emf = 0.507 V
(b) emf = 0.0507 V
(c) emf = 0.00234 V
Explanation:
Given;
number of turns of the coil, N = 40 turns
diameter of the coil, d = 11 cm
radius of the coil, r = 5.5 cm = 0.055 m
magnitude of the magnetic field, B = 0.4 T
The magnitude of the induced emf is calculated as;
(a) when the time, t = 0.3 s
(b) when the time, t = 3.0 s
(c) when the time, t = 65 s
Answer:
Explanation:
One prolonged blast every two minutes is an indication of incoming of a power-driven vessel underway. This blast is done to make aware other boats, about your location, in the conditions of poor visibility. The other boats will have to slow down their speed, in order to avoid collision.
