The disk's average angular speed during those 5 seconds was
(1/2) (100 + 300) rad/s = 200 rad/sec
Spinning for 5 sec at an average angular speed of 200 rad/s, the disk turned
(200 rad/s) x (5 s) = <em>1,000 radians</em>
(That's 500/pi revolutions = roughly 159.2 revolutions.)
Answer:

Explanation:
The period of the simple pendulum is:

Where:
- Cord length, in m.
- Gravity constant, in
.
Given that the same pendulum is test on each planet, the following relation is formed:

The ratio of the gravitational constant on planet CornTeen to the gravitational constant on planet Earth is:



Force = mass * acceleration
Force = 5000 * 1.5
Force = 7500 N
Answer:
2000 pieces
Explanation:
The number of tiles is given by dividing the area of room by the area of each tile. In this case,
thw areas are as shown below
Area of room is 8*10= 80 m2
Converting dimensions of tiles from cm to m then
Area of tiles is 0.2*0.2= 0.04 m2
No of tiles is 80/0.04=2000 tiles
The correct answer is D, h<span>e could place the bar magnet in the ball so that the south pole of the magnet is at the top of the ball and the compass needle points to it. I hope that this helps! Have a wonderful day</span>
