Answer:
1.318 * 10^(-2) m
Explanation:
Parameters given:
Frequency, f = 22.75 * 10^9 Hz
Velocity, v = 2.9979 * 10^8 m/s
Wavelength is given as:
Wavelength = v/f
Wavelength = (2.9979 * 10^8) / (22.75 * 10^9)
Wavelength = 0.01318 m = 1.318 * 10^(-2) m
The faster the job is done, the greater the power
Answer:
Thermogenesis:Your body's muscles, organs, and brain produce heat in a variety of ways
Explanation:
For example, muscles can produce heat by shivering. Hormonal thermogenesis: Your thyroid gland releases hormones to increase your metabolism. This increases the energy your body creates and the amount of heat it produces

Answer;
=15855.40 kg/m^3
Explanation;
Volume (V) of the cylinder = pi x r^2 x h
V = 3.14 x (44/2 x 10^-3)^2 x 41.5 x 10^-3
V = 6.307 x 10^-5 m^3
By density = m/V
mass = 1 kg
density = 1/(6.307 x 10^-5) = 15855.40 kg/m^3
