Are a very concentrated source of energy and are the form in which energy is stored in the body?

Fat is the body’s most concentrated source of energy, providing more than twice as much potential energy as carbohydrate (9 calories per gram versus 4 calories each per gram). Unlike one’s glycogen stores, which are limited, body fat is a virtually unlimited source of energy for athletes.

What type of energy transfer is eating?

The chemical energy in food can be converted to another form of chemical energy when it is stored as glucose or fat. It can be converted to thermal energy because our body produces heat when digesting our food. The chemical energy in our food can also be converted to mechanical energy in the form of muscle movement.

Does a microwave use mechanical energy?

Electricity is turned into microwaves where it is sent through the interior of the microwave appliance where it may or may not come into contact with water. If it does come into contact with water then the microwaves is transformed into mechanical energy.

Can microwaves go around corners?

Diffraction is when waves bend around the corner of an obstacle. So radio waves are good at “broadcasting” to many people, but microwaves are good at point-to-point communication. And for microwaves the transmitter and receiver must be “line of sight” (they can see each other).

What type of microwave does a GPS use?

MICROWAVE BANDS L-band microwaves, like those used by a Global Positioning System (GPS) receiver in your car, can also penetrate the canopy cover of forests to measure the soil moisture of rain forests. Most communication satellites use C-, X-, and Ku-bands to send signals to a ground station.

Does GPS use microwave?

Carrier Phase: GPS uses microwaves, and just like all light and radio waves, each signal has a unique frequency and wavelength. Although these waves do a great job of penetrating the atmosphere, they are still not capable of cooking a burrito from orbit.

Why use GPS in the microwave?

At some known time a satellite emits a signal in the form of microwaves. This signal reaches the receiver after a certain interval has passed. Since microwaves travel at the speed of light, a known velocity and a known time allows the receiver to determine the distance to the satellite.

What is the wavelength of GPS?

The L1 frequency is 1,575.42 MHz (wavelength 19.05 cm), the L2 frequency is 1,227.60 MHz (wavelength 24.45 cm), and the L5 frequency is 1,176.45 MHz (wavelength 25.48 cm). The GPS (L-band carrier) signals are broadcast radio waves. Broadcast radio waves are created by use of transmitters.

What is GPS P code?

Each satellite has a unique pseudo-random code. The C/A code is the basis for civilian GPS use. The second pseudo-random code is called the P (Precise) code. It repeats on a seven day cycle and modulates both the L1 and L2 carriers at a 10MHz rate. This code is intended for military users and can be encrypted.
