spin [16.1K]

Answer:

(a) the blocks all had different masses.

Explanation:

The surface is smooth, therefore coefficient of friction is tending to zero.

Forces for each blocks varied from 6N to 8N to 7N to 5N

The blocks were made of different materials and different materials are going to have varying weight for the same size of block.

Makovka662 [10]

The energy of a wave will remain constant if which of the following changes are made to it is given below

Explanation:

1.In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels. In water waves, energy is transferred through the vibration of the water particles.

2.First of all for light which is a electromagnetic wave c=frequency*wavelength. As the wavelength increases the frequency decreases. This can be physically understood as the increase in red shift of the light. Also energy =h*frequency,hence increasing wavelength decreases the energy carried by the photon.

3.Wave frequency is related to wave energy. the more energy in a wave, the higher its frequency. The lower the frequency is, the less energy in the wave.

A truck travels up a hill with a 5.4° incline. The truck has a constant speed of 25 m/s. What is the horizontal component of the
goldenfox [79]

Answer:

v_{x}=24.88m/s

v_{y}=2.35m/s

Explanation:

Knowing that the truck travels up a hill with a 5.4º incline

The horizontal component of the truck's velocity is:

v_{x}=vcos\beta=(25m/s)cos(5.4)=24.88m/s

The vertical component of the truck's velocity is:

v_{y}=vsin\beta=(25m/s)sin(5.4)=2.35m/s
