Answer:
Explanation:
Magnetic field due to a moving charge
B = μ₀ / 4π x (qv x r)/r²
Given
B = .3 X 10⁻⁶ T,
r = 60 x 10⁻³ m
Putting these values in the given equation
.3 x 10⁻⁶ = 10⁻⁷ x qvsinθ /( 60 x 10⁻³)²
θ = 90 °
qv = 10.8 x 10⁻³
At point P
Sinθ = 60 / 72
r² = 72 x 72 x 10⁻⁶
B = 
= 0.17 μT
The leaf fell at the crooked path instead of straight down because air currents and gravity applied changing and unbalanced forces to the leaf.
<h3>What is an air current?</h3>
An air current is defined as the changes in atmospheric pressure that causes the movement of air from one area to another.
When a leaf is detached naturally from the tree, it won't fall straight down to the floor but will fall a distance away from the tree due to the action of air current and some unbalanced forces.

The speed of electromagnetic waves in a vacuum is the same as the speed of light. It can be measured by finding the frequency and wavelength of two different waves, and then by that correlation, the speed of the waveform.
Hope this helps you (:
:D HI YOUR ANSWER WOULD BE 8 NEWTONS TO DA RIGHT
22N to right + 14N to left
Answer: The definition is a longitudinal wave is a wave consisting of a periodic disturbance or vibration that takes place in the same direction as the advance of the wave
