If a light ray strikes a flat mirror at an angle of 44° from horizontal the reflected ray will be​
ladessa [460]

Answer: The reflected ray will be 44 degrees.

Explanation: The Law of Reflection states the angle of incidence ( the incoming light ray) equals the angle of reflection ( the light ray being reflected) Therefore, the angle of reflection will be 44 degrees.

Hope that helped!

A 1.90-m-long barbell has a 25.0 kg weight on its left end and a 37.0 kg weight on its right end. if you ignore the weight of th
gregori [183]

Answer: The center of gravity is 1.1338 m away from the left side of the barbell

Explanation:

Length of the barbell = 1.90 m

The distance center of gravity from left = x

Mass on the left side = 25 kg

The distance center of gravity from right = 1.90 - x

Mass on the right side = 37 kg

At the balance point: m_1x_1=m_2x_2

25 kg\times x=37 kg\times (1.90-x)

x=1.1338 m

The center of gravity is 1.1338 m away from the left side of the barbell

A feather of mass 0.001 kg falls from a height of 2 m. Under realistic conditions, it experiences air resistance. Based on what
snow_tiger [21]

As per initial given conditions first we will find the initial potential energy of the feather

U = mgh

m = 0.001 kg

g = 9.8 m/s^2

h = 2m

U = (0.001kg)(9.8 m/s^2)(2m)

U = 0.0196 J

now we know that few amount of its initial energy is lost in form of frictional energy loss

so remaining energy will be less than the initial potential energy

So final answer would be

<u><em>A. KE < 0.0196 J</em></u>
