Answer:
Explanation:
Given parameters:
Initial velocity = 8m/s
Final velocity = 2m/s
Time taken = 3seconds
Unknown and solution:
1. Is he accelerating or decelerating?
Tranh is obviously decelerating in this period. This is negative form of acceleration in which the speed reduces as the body comes to a stop.
Deceleration is a negative change in velocity with time i.e a body is reducing its velocity as time is changing.
2. What is the value?
Mathematically;
Deceleration = 
Deceleration = 
= -2m/s²
Answer:
Rate of magnetic field is 15923.668 T/sec
Explanation:
We have given radius of loop conductor r = 2 mm = 0.002 m
Induced emf = 2 volt
As the magnetic field and plane are perpendicular to each other so angle between magnetic field and area is 0°
Cross sectional area of the conductor is equal to 
Induced emf is given by 
By using concave lens, we can correct Myopia and Hyperopia can be corrected by convex lenses.
To find the answer, we need to know about Myopia and Hyperopia.
<h3>
What is Myopia and
Hyperopia?</h3>
- Myopia is an optical defect, in which a person can see nearby objects clearly and cannot see far off objects clearly.
- Here the eyeball becomes too longer, and the focal length of eye lens become too short.
- It can be corrected by using concave lens.
- For Hyperopia, the person can see far off objects clearly and cannot see nearby objects clearly.
- This can be corrected by using convex lens.
Thus, we can conclude that, by using concave lens, we can correct Myopia and Hyperopia can be corrected by convex lenses.
