Answer:

m = 75 Kg

Explanation:

Given data:

Energy = 33750 J

Speed of object = 30 m/s

Mass of an object = ?

Solution:

Formula:

E = 1/2mv²

by putting values,

33750 J = 1/2 × m × (30 m/s)²

m = 2×33750 J/ (30 m/s)²

m = 67500 J /900 m²/s²

J = kgm²/s²

m = 75 Kg

Explain the difference between wavelength and frequency
Katyanochek1 [597]

Answer:

Wavelength (typically measured in nanometers) is the distance between two points in a wave.Frequency (typically measured in Hertz) is the number of waves in a specific time . Frequency and wavelength have both direct and inverse relationships. The crucial difference between frequency and wavelength is that frequency shows the total number of wave oscillations in a given time. As against wavelength specifies the distance between two specific points of a wave.

Explanation:

Frequency is how often something changes per second be it amplitude of a voltage on a wire or be it the bobbing back and forth of a bobblehead. Frequency is how often something moves up and down in a second. If a bobble head moves forward and backward in one second then it has a bobbling frequency of 1 Hertz (Hz). The unit of frequency is Hertz (Hz) or # of cycles or oscillations per second. A wavelength is measured in distance like meters (m). For photons or light or radiowaves the equation is wavelength=speed of light/frequency.
