apple, earth. earth more massive than moon. astronauts showed this - armstrong etc
Answer:
yes
Explanation:
The metal is closer than 20 cm to the magnet which is in the magnetic field.
It is more likely to be similar to his/her parents because the get half of their genetic code from their mom and half from their dad.
Answer:
<h3>The answer is 0.47 kg</h3>
Explanation:
The mass of the object given it's momentum and velocity can be found by using the formula

where
p is the momentum
v is the velocity
We have

We have the final answer as
<h3>0.47 kg</h3>
Hope this helps you
Answer:
331.75 V
Explanation:
Given:
Number of turns of the coil, N = 40 turns
Area, A = 0.06 m²
Magnetic Field, B = 0.4 T
Frequency, f = 55 Hz
Maximum induce emf, E₀ = NABω
but ω = 2πf
Maximum induce emf, E₀ = NAB(2πf₀)
Maximum induce emf, E₀ = 2πNABf₀
Where;
N is number of turns of the coil
A is area
B is magnetic field
ω is the angular velocity
f is the frequency
E₀ = 2 × π × 40 × 0.06 × 0.4 × 55
E₀ = 342.81 V
The maximum induced emf is 331.75 V
