You can describe the motion of an object by its position, speed, direction, and acceleration
Answer:
2m/s²
Explanation:
velocity = displacement (distance in a specified direction /time
Black balls with blue waffles
Answer:
Explanation:
"the velocity of the block is constant, so the net force acting on the block must be zero. Thus the normal force equals the weight and the force of friction equals the applied force" The only thing which is wrongly stated here is that the normal force equals the weight. Normal force is not always equal to weight. If external force is applied at some angle with the horizon , normal force may be more or less than weight. Even in case of an object placed on an inclined plane , weight is not equal to normal force .
All other parts of the statement are correct.
Radius of the circular loop is 0.0091m.
<h3>What is magnetic field?</h3>
Magnetic field is the area around a magnet where the magnetism influence is felt .
<h3>What is the magnetic field at the centre of a circular loop?</h3>
- The formula for magnetic field at the centre of a loop is
B =(μ)I/2r
- where B= Magnetic field at the centre of a circular loop
μ= Magnetic permeability =4(π)*10^(-7)
I= current flowing through the loop
r= radius of the loop
- Thus, radius of the loop =(4(π)×10^(-7)×5.7)/(2×3.9×10^(-4))
=0.0091m
Thus, we can conclude that the radius of the loop is 0.0091m .
