Answer:
1. The speed of infrared radiation is greater than radio wave radiation
2. The wavelength of infrared radiation is less than the radio wave radiation
Explanation:
Given:
The radio wave radiation N₁ is 3x10⁵ to 3x10⁷ Hz and the infrared radiation N₂ is 3x10¹¹ to 3x10¹⁴ Hz. The speed is:
1. The speed of infrared radiation is greater than radio wave radiation
2. The wavelength is:
λ = C/N
where more C, less λ
Then, the wavelength of infrared radiation is less than the radio wave radiation
Answer:
The torque on the lever is 30.0 N m.
Explanation:
Torque is defined as tendency of a force to rotate a body around its axis. Mathematically written as:
Force applied on the lever arm at 90°= 15 N
Distance at which force is applied = d = 2.0 m
The torque on the lever is 30.0 N m.
The correct answer is inertia
The answer is A. speed
hope this helps! :D
