Answer:
Microwave towers are telecommunications towers that use microwaves to transmit telephone and television signals to other microwave towers.
Explanation:
This technology replaced existing transmission wires, but it is almost entirely obsolete as of 2015 due to the advent of fiber optics and other modern methods of telecommunication.
Answer:
Explanation:
True
It is correct as the total rotational energy is the sum of transnational kinetic energy of each small piece of the object.
Consider a rigid body made of small particles each of mass dm have same angular velocity ω and the radius of the rotational path is r.
The velocity of each particle is v = r ω
So, the kinetic energy of each particle is
dK = 0.5 dm x v² = 0.5 x dm x r² x ω²
The total kinetic energy
K = 0.5 x I ω²
where, I is the moment of inertia
Using waves of frequency and pich
Explanation:
There's always been water around us
The answer is A because potential energy is stored up energy which means that it’s not moving
The SI unit of energy is the Joule .
Any kind of energy ... electrical, mechanical, nuclear, solar,
wind etc. It's easy to change from one form to another ... we
do it every day ... and they all have the same unit.
