Answer:
4.14 cm.
Explanation:
Given,
For Coil 1
radius of coil, r₁ = 5.6 cm
Magnetic field, B₁ = 0.24 T
For Coil 2
radius of coil, r₂ = ?
Magnetic field, B₂ = 0.44 T
Using formula of maximum torque
Since both the coil experience same maximum torques
now,
Radius of the coil 2 is equal to 4.14 cm.
Answer:
we would have no oxygen and barely any water.
Explanation:
It is given that,
Initial speed of the automobile, u = 65 km/hr =
Final speed of the automobile, v = 0
Deceleration of the automobile, 
We need to find the distance covered by the car as it comes to rest. It can be calculated using third equation of motion as :
So, the acceleration of the car is 
. Hence, this is the required solution.
Answer:
Explanation:
When the two or more forces acting on a body such tat the net force on the body or the acceleration of the body is zero, then such forces are balanced forces.
For example, in the game of tug of war, both the teams pulls the rope with same force but in opposite directions so that the net acceleration is zero it means a balanced force is acting on the rope.
When tow or more forces acting on a body and there is some net force or acceleration of the body, then the forces are said to be unbalanced.
For example, if we push a box along the plane, the net force is non zero and the forces are unbalanced.
