Answer:
c. The coefficient of kinetic friction is less than the coefficient of static friction
Explanation:
When the box finally does break loose. Then the component of the box weight which is parallel to the board weight parallel component, is equal to the .
For the box to acce;erate thee must be non-zero net force acting on the box parallel to the board. Or we can say,
Therefore the force of kinetic friction must be less than the force of static friction. Thus,
Answer:
The magnetic force on the section of wire is .
Explanation:
Given that,
Current
Length = 0.750 m
Magnetic field
We need to calculate the magnetic force on the section of wire
Using formula of magnetic force
Since,
Hence, The magnetic force on the section of wire is .
Answer:
F= 134.92 N
Explanation:
Given that
The mass of the moon ,M = 7.4 x 10²² kg
The mass of the man ,m = 79 kg
The radius ,R= 1.7 x 10⁶ m
The force exerted by moon is given as
Now by putting the values in the above equation we get
Therefore the force will be 134.92 N.
F= 134.92 N
