6 0

Answer:

Red light has a longer wavelength and lower frequency than blue light.

Explanation:

The photon energy carried by the red light is lower than blue light. The higher the frequency of the photon, the greater its energy and the greater its wavelength, the lower its energy. Thus, red light has a longer wavelength and lower frequency than blue light.

Trava [24]

Answer:

3 N to the right

Explanation:

There are two forces acting on the car:

- A force of 10 N towards the right

- A force of 7 N towards the left

Therefore, the net force is given by the difference between the two, since they are in opposite directions:

F=10 N-7 N=3 N

And the direction is to the right, since the force to the right has greater magnitude than the force to the left.

I don’t understand how to do this
anzhelika [568]

Explanation:

A) Use Hooke's law to find the spring constant.

F = kx

40 N = k (0.4 m)

k = 100 N/m

B) Period of a spring-mass system is:

T = 2π √(m / k)

T = 2π √(2.6 kg / 100 N/m)

T = 1 s

Frequency is the inverse of period.

f = 1 / T

f = 1 Hz

____ [38]

Answer: Please find the answer in the explanation

Explanation: According to the Newton 3rd law of motion which state that;

In every action, there will be equal and opposite reaction.

when the piston of a fountain pen with a nib is dipped into ink and and the air is released by pressing it, a force is applied which act on the molecules of the ink by pushing the molecules. When the force is released, there will be a reaction force by pulling the molecules of the ink into the pen. Thereby the ink fills in the pen.
