Answer:
The angular distance in revolution is 
The angular distance in radians is 
The angular distance in degrees is 
The angular size is 
Explanation:
From the question we are told that
The diameter is 
The distance moved by the rim is 
Generally the circumference of the pie plate is mathematically represented as
Substituting the values
The number resolution carried out by the pie plate is evaluated as
Substituting value
The angular distance 
is mathematically evaluated as
Where r is the radius which is mathematically evaluated as
Substituting this into the equation for angular distance
The angular distance traveled in degrees is
When the pie is cut into 9 equal parts
The angular size would be mathematically evaluated as
Under the assumption that the three rocks are dropped from the same height, they will hit the ground at the same speed. The gravity of Earth is virtually the same for any object that is small compared to the size of the Earth. The acceleration will change with the distance from the Earth, but this change is so small for the range of heights we work with (consider the range of heights from sea level to the tip of Mount Everest) that we can take the average value and assume it to be constant. This constant value of acceleration due to Earth's gravity is 9.80665m/s²
Because the objects fall under the same constant acceleration, they will hit the ground at the same speed.
The correct answer is elastic potential energy.
I hoped this helped!
The capacitor is used to store electric charge.That is what makes capacitors special. <span>
The charge that flows into the capacitor is stored on the plate of the capacitor that the source voltage is connected to. </span>When current flows into a capacitor, the charges get “stuck” on the plates because they can’t get past the insulating dielectric. One plate is positively charged and the other negatively <span>The stationary charges on these plates create an </span>electric field. <span>When charges group together on a capacitor like this, the cap is storing electric energy just as a battery might store chemical energy.</span>
Yes. A roulette ball circulating in a spinning wheel, a car going around a curved
road at 30 mph, and a planet in a circular orbit are all being accelerated.
"Acceleration" does NOT mean "speeding up". It means any change in the
speed or DIRECTION of motion.
