False. When a chemical reaction occurs, atoms don't create or destroy. They are rearranged as bonds and are broken and formed together.
Answer:
The induced emf is 
Explanation:
From the question we are told that
The radius of the circular loop is 
The intensity of the wave is 
The wavelength is 
Generally the intensity is mathematically represented as
Here 
is the permeability of free space with value
B is the magnetic field which can be mathematically represented from the equation as
substituting values
The area is mathematically represented as
substituting values
The angular velocity is mathematically represented as
substituting values
Generally the induced emf is mathematically represented as
At maximum induced emf 
So
substituting values
Answer:
Guysi hate math answer this guy plsss ssss
When a woman walks south at a speed of 2.0mph for 60 minutes. She then turns around and walks north at a distance of 3000m in 25 minutes. then the woman's average speed during her entire motion would be 73.15 meters /minute.
<h3>What is speed?</h3>
The total distance covered by any object per unit of time is known as speed.
the mathematical expression for speed is given by
speed = total; distance /total time
As given in the problem a woman walks south at a speed of 2.0mph for 60 minutes
60 min = 1 hour
1 mile = 1.60934 km
The distance covered by her southwards = speed ×time
=2 mph × 60 minutes
= 3.218 km
She then turns around and walks north at a distance of 3000m in 25 minutes
The distance covered northward is 3000m
speed = total distance /total time
=(3218 +3000) /(60+25)
=73.15 meters /minutes
Thus, The average speed of the woman would be 73.15 meters /minute.
