Metal bar is aligned along East- West direction and it is dropped vertically down
So its velocity is along -Z direction,
Now the Earth's magnetic field is towards north so its towards +Y direction
now we have formula for force on a moving charge
v = - z direction
B = + y direction
now by the above formula
So force is towards East
so all positive charge is towards East end
grams, kilograms, pounds for mass
newtons for weight
The main environmental effects of ozone depletion could include the following:
- higher risk of skin cancer
- sunburns
- quick ageing
- weakend immune system
<h3>What is ozone depletion?</h3>
Ozone depletion is the gradual thinning of the ozone layer in the upper atmosphere as a result of the relelase of chemical compounds or gases.
Ozone layer helps prevent the Earth surface against incoming ultraviolet radiations that could cause damage to our environment.
Therefore, the main environmental effects of ozone depletion could include the following:
- higher risk of skin cancer
- sunburns
- quick ageing
- weakend immune system
