Answer:
Explanation:
a) ω = 9000 rev/min (2π rad/rev) / 60 s/min = 942.47779... = 940 rad/s
b) F = mω²R = 0.010(942.4777²)0.20 = 1,776.52879... = 1800 N
Answer:
a. The blue light is bent toward the normal more than the red light.
Explanation:
When light travels from a less dense medium, in this case air into a denser medium (glass) it is bent towards the normal because of the reduction in speed due to the dense medium.In this scenario we have the same incident angle of 30º. therefore, we consider the wavelength of the light because at shorter wavelengths we have more refraction occurring as compared to longer wavelengths. We know that Blue light has a shorter wavelength as compared to red light, which means it will bend toward the normal more than the red light.
Answer:
We conclude that the mass of a rock with a force of 500 N and an acceleration of 75 m/s² is 6.7 kg.
Hence, option D is correct.
Explanation:
Given
To determine
Mass m = ?
Important Tip:
-
The mass of a rock can be found using the formula F = ma
Using the formula
where
- a is the acceleration (m/s²)
now substituting F = 500, and a = 75 m/s² in the formula
switch sides
Divide both sides by 75
simplify
kg
Therefore, we conclude that the mass of a rock with a force of 500 N and an acceleration of 75 m/s² is 6.7 kg.
Hence, option D is correct.
