Answer: s=delta/360° ×2πr
Explanation:
The center of the wheel is located.The distance from the centre spoke to the outside wheel is the radius r...the distance between two spokes in the wheels is an arc which forms an angle(theta) at the centre... It is a fraction of the angle formed at the middle to the total angle of the wheel(360° as in circle) to the product of the circumference of the wheel(circle)
Length of arc(s)=theta/360 ×2πr
Answer:
While In an <em><u>ideal/isolated</u></em> system, as long as the object is not in motion, its potential energy will be the same.
However, <u>potential energy is relative</u>. On Earth, usually, it is measured with respect to gravity. <u>The higher the object, the greater the potential gravitational energy</u>. It's all relative. For the sake of this question, I would assume that potential energy increases.
Explanation:
While kinetic energy depends upon speed, potential energy is always relative to some arbitrary reference point.

Answer:
Diffraction.
Explanation:
Diffraction is the bending and scattering of a wave as it hits an object or goes through an opening.
Waves can be described using a number of different characteristics of a wave. Wavelength and frequency are two such characteristics. The relationship between wavelength and frequency is that the frequency of a wave multiplied by its wavelength gives the speed of the wave
Answer:
The answer is A
Explanation:
Here's an example. A child is in school taking a test. They have made a mistake on a question, and want to erase it. The eraser is made out of a type of rubber, the rubber has friction, which means the eraser has something that's going to resist movement. Now the child has exerted enough force to get it moving, and it's moving, it won't stop unless the child stops exerting force to keep it moving. Both Newton's 1st and 3rd law explain the action of moving something on a surface with friction.
