1. Radio waves are generated by a transmitter and detected by a reciever. The reciever then encodes the radio wave into information to transport into your radio. You may have listened to either AM or FM radio.

2. Cell phones creates up and down sounds with the microphone. The microchip inside the phone turns those up and down sounds into numbers, and sends it off to the cell tower. The cell tower processes those numbers and sends it off to the phone you are trying to call.

3. The television service delivers programming to viewers by relaying information to communications satellites that can be found orbiting the earth. The satellite receiver decodes the programming to the viewer’s TV.

That which type of boundary do lithospheric plates collide
satela [25.4K]

Answer

The type of boundary formed when lithospheric plates collide is called Convergent boundary

Explanation

When plates of the lithosphere collide, they form a sub-duction zone where the denser plate will be subdued underneath the less dense one. The one subdued later melts and get destroyed. This boundary occurs when; ocean crust meets ocean crust, when oceanic and continental crust meet   and where continental crust meets continental crust.

An electric clothes dryer draws 15 a of current from a 240-v wall outlet. how much power, in watts, does it use?
Nataly [62]
The power consumed by the electric clothes dryer may be calculated by the following equation,

    P = I x V

where P is the power, I is the current in amperes, and V is the voltage in volts. Substituting the known values from the given above,

  P = (15 A)(240 V)
  P = 3600 watts

Therefore, the power consumed by the electric clothes dryer is equal to 3600 watts.

In the formula V =E ^b d ^a, if V, E and d are the velocity longitudinal waves, bulk modulus of elasticity and density of the ga
maxonik [38]

Answer:

b=\frac{1}{2} and a=-\frac{1}{2}

Explanation:

The velocity longitudinal waves depends on the bulk modulus and the density. It is given by the formula:

V=\sqrt{\frac{\beta }{\rho} }

Where V is the velocity , β is the bulk modulus and ρ is the density.

V=\sqrt{\frac{\beta }{\rho} }\\V=\frac{\beta^\frac{1}{2} }{\rho^\frac{1}{2} } \\V=\beta^\frac{1}{2} \rho^-\frac{1}{2}

Therefore comparing with V =E ^b d ^a, where V, E and d are the velocity longitudinal waves, bulk modulus of elasticity and density, the values of b and a can be gotten.

Therefore, b=\frac{1}{2} and a=-\frac{1}{2}
