Answer:
Explanation:
We just have to calculate what angular displacement a ball with an average angular velocity of 290 rev/min experiments in 0.64s. By definition, angular velocity is the angular displacement divided by the time elapsed:
Since and , we can covert:
Where the terms between parenthesis are equal to 1, so they just change the units. Then for our values we have:
You are exerting 100N. Since there’s no NET force, then there must be exactly 100N pushing exactly back on your 100N to cancel it to exactly zero. Newton's first law states that whether a body is at rest or travelling in a straight line at a constant speed, it will remain at rest or continue to move in a straight line at a constant speed unless acted upon by a force.

Answer:
1. Installing solar panels on the roof. This is an example of renewable energy, and solar panels help provide electricity for a home.
2. Using LED lights instead of traditional lightbulbs. The modern LED lights use much less electricity and function up to 90% more efficiently than the traditional lightbulbs.
3. Using rain barrels to collect water from the roof. Installing rain barrels to collect rainwater to water your plants and garden is a great way to save water and cut down on your water bill.
Hope this helps! :)
