Answer:
The magnitude of the magnetic field inside the solenoid is 1.5 × 10⁻²T
Explanation:
Given that,
Length = 40 cm
Radius = 0.040 cm
Number of turns = 400
Current = 12 A
We need to calculate the magnetic field
Using formula of magnetic field inside the solenoid
Where,=Number of turns per unit length
I = current
B = magnetic field
Put the value into the formula
Hence, The magnitude of the magnetic field inside the solenoid is 1.5 × 10⁻²T
Hello
The period of a wave is the time it takes between two complete oscillations of the wave itself, i.e. it is the time that occurs between two consecutive wavelengths. Therefore, if we want to calculate how many wavelengths pass a certain point in
, we need to divide the total time for the period of the wave, T:
So, the answer is 8 wavelengths.

Answer:
a) v² = G M R³, b) T = 2π /, c)
Explanation:
a) The kinetic energy is
K = ½ m v²
to find the velocity let's use Newton's second law
F = m a
acceleration is centripetal
a = v² / R
force is the universal force of attraction
F = G m M / r²
we substitute
G m M R² = m v² R
v² = G M R³
the kinetic energy is
K = ½ m G M R³
b) angular and linear velocity are related
v = w R
w = v / R
w =
w =
the angular velocity is related to the period
w = 2π / T
T = 2π / w
we substitute
T = 2π /
c) the angular moeomto is
L = m v r
L = m RA G M R³ R
L =
