2 seconds is the period (time it takes to complete one cycle)
Answer: A. Frequency
B. Wavelength
Explanation: Electromagnetic waves are waves which can travel through the vacuum. Electromagnetic waves have electrical and magnetic component associated with them.
Electromagnetic waves are arranged in order of increasing frequencies or decreasing wavelengths.
Radio waves, X-rays, and gamma rays are all electromagnetic waves which have different wavelengths and thus have different frequencies. But they all travel with the speed of light.

The order of frequency of given waves : gamma rays > X rays> Radio waves.
The order of wavelength of given waves : gamma rays < X rays < Radio waves.
Answer:
epithelial, muscle, nervous, and connective tissues.
Explanation:
The concept that should be used here is that heat loss is equal to heat gain. In this item, the heat lost by the aluminum pan should be equal to the heat gained by water. Such that,
750 g(0.215 cal/g°C)(T - 24) = (10000 g)(1 cal/g°C)(4°C)
The value of T from the equation is equal to 272°C.
