Answer:
The maximum speed of the stone without breaking the rope is 4.33 m/s.
Explanation:
Given;
maximum tension the rope can withstand, T = 75 N
mass of the rock, m = 6 kg
radius of the circle, r = 1.5 m
As the stone spin in a vertical circle, it performs circular motion with centripetal acceleration directed inwards. The maximum centripetal force during this motion will be equal to maximum tension on the rope.
Therefore, the maximum speed of the stone without breaking the rope is 4.33 m/s.
Answer:
As the electrons (tiny particles inside atoms) in the electric current wiggle back and forth along the antenna, they create invisibleelectromagnetic radiation in the form ofradio waves. ... 1) Electricity flowing into the transmitter antenna makes electrons vibrate up and down it, producing radio waves.
Answer:
Explanation:
given ;
- coefficient of kinetic friction = 0.80
- considering the force acting in horizontal direction and from newton's 2nd law of motion;
- for vertical motion = Fn - mg = 0
- for horizontal motion = F = ma + miu mg = m( a + miu.g)
- therefore, F = miu mg where g = 9.81m/s^2
- plugging the values into the equation;
Horizontal force = 204.05N
