B
Explanation:
The answer is b. gymnastics
The wavelength of violet light with a frequency of 750 × 10^12 Hz is 400 nanometers (nm).
Wavelength is the distance between two consecutive peaks or troughs of a wave, representing the length of one complete cycle of the wave. It is commonly used to describe the size or scale of various types of waves, including electromagnetic waves such as light.
To calculate the wavelength of light, you can use the formula:
wavelength = speed of light/frequency
The speed of light is approximately 3.00 × 10^8 meters per second.
Let's plug in the values:
frequency = 750 × 10^12 Hz
speed of light = 3.00 × 10^8 m/s
wavelength = (3.00 × 10^8 m/s) / (750 × 10^12 Hz)
Simplifying the expression:
wavelength = (3.00 / 750) × (10^8 / 10^12) m
wavelength = 4.00 × 10^-4 m
Therefore, the wavelength of violet light is approximately 4.00 × 10^-4 meters or 400 nanometers (nm).

Answer:
Explanation:
r = v^2 / g
where:
r is the radius of the path (in meters)
v is the speed of the car (in meters per second)
g is the acceleration due to gravity (in meters per second squared)
In this case, v = 29 m/s and g = 9.81 m/s^2. Therefore, the radius of the car's path is:
r = 29^2 / 9.81 = 82.5 meters
So the answer is 82.5
