Hello,
The balloon sticks to a sweater after it has been rubbed against it because once you rub a balloon against the sweater, the balloon steals electrons from the sweater, which leaves the sweater positively charged and the balloon negatively charged.
Mark brainliest if helped!
The solution for this problem is:torque1 = torque2 = FL / 2
Torque 3 = Torque 4 = FL / 2 * sin (theta)
Torque 5 = 2 FL
Torque 6 = 0
So the order of the torques from smallest to largest is torque 6, (torque 3 and 4), (torque 1 and 2), torque 5.
Remember or just take note that sin (theta) < 1 is why 3 and 4 are less than 1 and 2.
Answer:
By pushing the pendulum Bob up so it moves faster
Explanation:
In pendulum physics the length of the pendulum Bob determines the speed of the clock. So since the grandfather's clock is slow it means the Bob is has moved down so to move it up you have to achieve this by adjusting the but upwards thereby making the clock move faster.
Answer:
The current through the tube is 73.39A.
Explanation:
The relationship between the resistivity , the electric field , and the current density is given by
This equation can be solved for to get:
Since the current is
Now, for the tube of mercury , , and the area is ; therefore,
Hence, the current through the mercury tube is 73.39A.
