-- 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:
The current flows through the rod is 14.9 A.
Explanation:
Given that,
Magnetic field = 0.045 T
Mass of aluminum rod = 0.19 kg
Length = 1.6 m
Angle = 30.0°
We need to calculate the force
Using resolving force


Put the value into the formula


We need to calculate the current flows through the rod
Using formula of magnetic force


Put the value into the formula

Hence, The current flows through the rod is 14.9 A.
Answer:
see below
Explanation:
You will need t find the volume of the sphere
4/3 pi r^3 divide into the mass
1431 / (4/3 pi (5.8)^3) = 14 gm /cm^3
