Answer:
Once the fridge is moving you are still applying the same push force but now the opposing friction (now kinetic) force is less.
Answer:
Newton's law of universal gravitation states that every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Explanation:
Correct answer choice is :
A) As speed changes, wavelength changes and frequency remains constant.
Explanation:
The higher the energy, the higher the frequency and the smaller the wavelength. The relation among wavelength and frequency the greater the frequency, the smaller the wavelength it reflects that short wavelengths are more dynamic than large wavelengths. The wavelength and frequency of light are almost associated. The greater the frequency, the smaller the wavelength. Because all small waves move into space at the very speed, the amount of wave peaks spending by a read point in one second depends on the wavelength.
Answer:
16.8 lb is the force on the brake pad of one wheel.
Explanation:
Force applied on the piston = 
Area of the piston = 
Force applied on the brakes = 
Area of the brakes = 
Applying Pascal's law: 'For an incompressible fluid pressure at one surface is equal to the pressure at other surface'.
16.8 lb is the force on the brake pad of one wheel.
