Answer:bowling ball has greater kinetic energy
Explanation:
Kinetic energy of bowling ball:
mass=m=5kg
Velocity=v=6m/s
Kinetic energy =ke
Ke=0.5 x m x v x v
Ke=0.5 x 5 x 6 x 6
Ke=90J
Kinetic energy of ship:
mass=m=120000kg
velocity=v=0.02m/s
Ke=0.5 x m x v x v
Ke=0.5 x 120000 x 0.02 x 0.02
Ke=24J
The atom has 71 protons.
(The atomic number of a chemical element is the number of protons found in the nucleus of an atom)

Answer:
B = 0.135T
Explanation:
To find the magnitude of the magnetic field you use the following formula, for the torque produced by a magnetic field B in a loop:
(1)
τ: torque = 1.51*10^-5 Nm
I: current = 2.47mA = 2.47*10^-3 A
B: magnitude of the magnetic field
A: area of the loop = 4.97cm^2 = 4.97(10^-2m)^2=4.97*10^-4m^2
N: turns = 181
θ: angle between B and the magnetic dipole (same as the direction of the normal to the plane)
You replace the values of the parameters in (1). Furthermore you do B the subject of the formula:

Answer:
it expands by 11 cm.
Explanation:
First we need the coefficient of linear thermal expansion of steel
a = 12e-6/K
Now we use the equation for linear thermal expansion
L1 = L0 * (1 + a * (t1 - t0))
Where
L0: length before expansion
L1: expanded length
t0: temperature before expansion
t1: temperature expanded
L1 = 403 * (1 + 12e-6 * (24 - 1.22)) = 403.11 m
It expanded 11 cm.
