The moon orbiting the Earth
Explanation:
The motion of the moon orbiting the earth is a circular motion. Circular motion is simply the motion of an object in circle at constant speed.
- A cannonball flying from a cannon is a projectile motion and not a circular motion.
- A car moving along a straight track is a linear/translational motion.
- Pendulum of a grandfather clock is a simple harmonic motion.

1) Equivalent resistance, 1/R = 1/15 + 1/40 + 1/60 = 8+3+2 /120 = 13/120
R = 120/13 = 9.23
2) Current, I = V/R = 115/9.23 = 12.45 A
Answer:
W = 113.98 N
Explanation:
Given that,
Radius of Potatoine
Mass of Potatoine, 
Mass of Marvin, m = 35 kg
We need to find his weight on Potatoine. Weight of an object is given by :
W = mg
g is acceleration due to gravity, 
So,
So, his weight on Potatoine is 113.98 N.
C. It decreases
Cuz you know two objects are moving apart from each other the gravitational attraction between them is decreasing. as well as the gravitational force.
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.
