The wavelength of a microwave of 3 x 10^9 Hz frequency is 0.1 m.
The wavelength of a microwave of 3 x 10^9 Hz frequency is calculated using the equation λ = c/f, where λ is the wavelength, c is the speed of light, and f is the frequency.
The speed of light is approximately 3 x 10^8 m/s. Therefore, the wavelength of a microwave of 3 x 10^9 Hz frequency can be calculated as follows:
λ = 3 x 10^8 m/s/3 x 10^9 Hz
= 0.1 m.
Therefore,the wavelength of a microwave of 3 x 10^9 Hz frequency is 0.1 m.
Microwaves are electromagnetic waves that have a frequency between 300 MHz to 300 GHz and a wavelength from 1 mm to 1 m. Microwaves have a variety of uses, including communications, radar, and cooking. Microwave radiation is absorbed by water, fats, and sugars, which is why it is used for cooking.
The frequency of a microwave is usually expressed in megahertz (MHz) or gigahertz (GHz). One megahertz is equal to one million hertz and one gigahertz is equal to one billion hertz. The frequency of a microwave determines its wavelength; the higher the frequency, the shorter the wavelength.

Surface Tension. Molecules on the surface experience cohesion, this means molecules that are the same material stick together.
Answer:
a reference point allows you to determine the motion of an object :)
example: when your in a car and u look out the window and your moving fast than the car next to you. It seems that way because the car next to you is actually moving much slower.
Answer:
Torque = 1191.68 N-m
Explanation:
Given data
mass m = 76 kg
standingdistance r = 1.6 m
Solution
we get here torque that si express as
torque = force × distance ................1
torque = r × F sin(theta)
and we know that
F = mg .........2
and g = 9.8 m/s²
put here value in equation 1 we get
Torque = 76 × 1.6 × 9.8 × sin(90)
Torque = 1191.68 N-m
