(a) The average speed from A to B would be 1.76 metre per second and the average velocity from A to B would also be 1.76 metre per second
<span>(b) The average speed from A to C would be 1.73 metre per second and the average velocity from A to C would be 0.87 metre per second</span>
Answer:
hey mate here is your answer
So if an object has a very small velocity (not moving very far over time, even though a large force may be applied to it, the Power will remain small. ... Stepping on the gas, or "speeding up" the car, is applying a force which will increase velocity and increase power.
please mark me as a brainliest
<h3><u>Answer;</u></h3>
producing a path for current to flow
<h3><u>Explanation;</u></h3>
- An AC generator is a device that converts mechanical energy into electrical energy using the principle of electromagnetic induction.
- <em><u>Slip rings are two hollow rings to which two ends of the armature coil are connected. These rings rotate with the rotation of the coil. They function to to allow for electrical contact with the brushes.</u></em>
- Slip rings therefore, provide a means for connecting the rotating armature to an external circuit.
Answer:
The momentum is 1.94 kg m/s.
Explanation:
To solve this problem we equate the potential energy of the spring with the kinetic energy of the ball.
The potential energy of the compressed spring is given by
,
where is the length of compression and is the spring constant.
And the kinetic energy of the ball is
When the spring is released all of the potential energy of the spring goes into the kinetic energy of the ball; therefore,
solving for we get:
And since momentum of the ball is ,
Putting in numbers we get:
Answer:
c. Both signals are simultaneous.
Explanation:
The speed of light is the same in all frame of reference.
Since an observer inside the ship receives both signals at the same time, then the signals from both flashlight are simultaneously.
