Answer:
rubber ball
Explanation:
basically friction is caused by little electrical bonds at a molecular level. the ice had more bonds due to it being a cube rather than a ball which has one point of contact. this means less energy is needed to put the ball in motion than the ice cube.
Answer:
The amount of time is 31.45 sec.
Explanation:
Given that,
Voltage = 10.0 V
Resistance
Capacitance
We need to calculate the time constant
Using formula of time constant
Put the value into the formula
The amount of time required for the current in the circuit to decay to 4.00% of its original value.
We need to calculate the amount of time
Using formula of charge
Put the value into the formula
Hence, The amount of time is 31.45 sec.
Science like this is being used when it comes to tornados. They have special robots and equipment that travel inside the cone and measure the speed and width of the tornado. This information is processed back to the meterologists and this helps the public get to safety in a split second.
So we want to explain the effects of time dilation. In theory of relativity time dilation is the difference of elapsed time between two events when measured by two observers who are moving relatively to each other. A clock of an observer that is standing still in an inertial frame of reference is going to measure a different time of an event than the clock of an observer that is moving with some velocity with respect to the inertial reference frame that is not moving. In a nutshell, the moving clock is ticking slower than the clock that is standing still.
