#### exists and is an alternate of .

Usually we use a mechanical or electrical meter. Gas supplies can simply drive round a counter. Electricity can be measured in several ways, for instance by using part of it to turn a disc which in turn drives a counter. Essentially we measure how much power we use and for how long. The unit is usually kilowatt-hours.

# What laboratory methods are used to determine the energy content of foods?

calorimeter . although not most accuratethe simplest way to test the energy content of foods is using a calorimeter, this is basically a insulated copper beaker filled wit

WATTMETER

# What is the equation used to determine the energy content of a packet of light of specific frequency?

Planck's Equation, E = hv Where E is the energy contained within the photon of light, h is Plank's constant, and v is the frequency of the light. Planck's constant, h, = 6.62

# What is the formula you use to determine the gravitational potential energy of an object?

Weight x Height = Potential energy The units and the calculation are the same as for work. Work is force through a distance. Get the weight in the SI by multiplying the mass

# What is the formula you use to determine the gravitional potential energy of a object?

The gravitational potential energy of an object is given by: Ug=mgy M is the mass, g is the gravitational constant, and y is the height of the object.

# To determine energy band gap of a semiconductor using four probe method?

Probes connect the metal and semi conductors so that we can allow the flow of current as germanium could not produce current.Probe provides a physical contact with germanium.

# What formula do you use to determine the amount of energy used by an appliance?

The total amount of energy used by an appliance is equal to the power consumption multiplied by the time the appliance is in use. E = P x T ENERGY=POWERxTIME DDASIA

# What is formula you use to determine the gravitational potential energy of an object?

PE = mgh, that is, mass x gravitation x height. Or simply weight times height, since weight is already equal to mass times gravitation.\n\n. On Earth, you would usually use 9

# Why a Gm counter is not useful for determining absorbed energy in a gas?

The Geiger-Meuller detector operates in avalanche mode, meaning that each ionization interaction results in a full pulse on the detector. Each pulse, then, is not proportiona

# What factors determine whether a source of energy is useful?

1 Whether it is a renewable resource, (a resource that naturally renews itself, like solar power or wind) 2 Its cost effectiveness (does it help reduce the cost of energy in

# Which gland determines the rate at which the human body uses energy?

The anterior pituitary gland.

# What is the formula used to determine the gravitational potenital energy of an object?

PE = mgh Potential energy = mass x gravity x height In SI units: Joules = kilograms x meters/second 2 x meters Standard Earth gravity is about 9.8 meters/second 2 .
In Math and Arithmetic

# What formula do you use to determine the Gravitational potential energy of an object?

Gravitational potential energy = (weight of the object) x (height) or Potential energy = (mass) x (acceleration of gravity) x (height)

# What do nutritionists use to determine how much energy you get from food?

they look at how many poopie fibers are in it then they add their own and feed it to your moms vagina.
In Human Anatomy and Physiology

# How do you determine the amount of electrical energy used by a device?

Measure the current flowing through the device and the voltage across it; multiply the current by the voltage to get the power in Watts. Watts = Volts x Amps ; Watts = Amps
