Im 70 percent sure that the right answer is chromosphere
The answer is a Mid-Ocean ridge.
Distance can be equal to displacement ... if the motion is all in a straight line ... but distance can never be greater than displacement.
Answer:
All are true except the last point that says that a battery is a current source and the current at the outlet is always the same.
Explanation:
- A battery is an electro-chemical device which converts the chemical energy into usable electrical energy thus it provides electrical energy.
- Since, the battery maintains a a constant potential difference between its terminals, once connected.
- Since, the movement of electric current requires energy, which is supplied by the electric potential energy stored in the battery.
- The current in the battery flows as per the Ohm's law and we can not say that the current leaving will always remain constant.
- As the current is the flow of electric charge, and charges are not stored in batteries unlike capacitors, thus the current at the leaving end will depend on Ohm's law and will vary accordingly.
Answer:
Diana's speed relative to ground is <u>16 km/h</u> in the direction of motion of train.
Explanation:
Given:
Velocity of train in forward direction is, 
Here, 
Velocity of Diana relative to train in the backward direction is, 
Negative sign implies backward motion or motion opposite to the direction of train's motion. Here, Diana is walking from front of train to back. So, Diana is moving in the opposite direction.
Now, we know that, for two bodies 'A' and 'B', velocity of 'A' relative to ground is given as:
Therefore, velocity of Diana relative to ground is given as:
So, Diana's speed relative to ground is 16 km/h in the direction of motion of train.
