Answer 2
Answer:

Hey There!

The device used to determine if there is energy in a wire is called a clamp meter, this device would detect if there are any presents currents in the wire. In order to use this device, you would simply have to attach it on the wire you are testing for.

Another device used to detect energy from wires is called a a non-contact voltage detector. While this device does not operate on all types of wires, it is solely created for AC circuits. Though, it is not preferred to manage the wire as this device sometimes proves to not be very reliable.

Answers

Answer: Ribosome

Explanation:

The protein formation inside the body takes place in the cell organelle named ribosome. Protein is a every essential component of the body.

It serves many functions in the body of all the eukaryotic organism. It is found on the body surface as the body guard to kill the invading pathogens, all the enzymes inside the body are protein.

The ribosomes inside the cell can be attached to the endoplasmic reticulum or can be found floating inside the cell.

The proteins are synthesized both by the floating and attached ribosomes. The proteins produced by the floating ribosomes are used inside the cell and the proteins made by rough Endoplasmic reticulum are most of the time sent outside the cell.

Answer:

B. ribosome

Explanation:

In the ribosomes, the codons get paired with anti codons to create a polypeptide or protein.

the energy of a photon is 1,000 calories what is the wavelength of the radiation? ( 1 calorie equals 4.184 joules )

Answers

Answer:

Explanation:

One food Calorie is equal to 1 kilocalorie, that is, 1000 calories. A SI unit of energy is the joule (symbol J), where 1 cal = 4.184 J. The heat produced by chemical reactions is often expressed in kilocalories, as well as in kilojoules (kJ), where 1 kcal = 4.184 kJ.

Final answer:

First, we convert the energy of the photon to Joules. Then, we use the equation for energy of a photon, E=hc/λ, rearranged to solve for λ (wavelength). Substituting the known values into this equation, we can calculate the wavelength of the photon.

Explanation:

The energy of a photon is given in calories, but in physics, it's usually measured in Joules, so we first need to convert our energy to the appropriate unit. Thus, the energy of the photon is 4184 Joules (1,000 calories x 4.184 Joules/calorie).

The energy of a photon is also related to its wavelength through the equation E=hc/λ, where h is Planck's constant (6.63 x 10^-34 J.s) and c is the speed of light (3.00 x 10^8 m/s). By rearranging the equation, we find λ=hc/E. Substituting the given numbers for Planck's constant, the speed of light, and the energy of the photon, we find that λ = (6.63 x 10^-34 J.s)(3.00 x 10^8 m/s) / 4184 J.

Calculating these values, we will arrive at the wavelength of the radiation emitted by this photon.

What is the result of friction

Answers

A result of friction is heat. Anytime friction occurs between two pieces of matter, some sort of heat is cretated. Rub your hands together with force, and you will notice that they become warm. This is because the kinetic energy of the moving mass is not lost when the object slows down due to friction. Instead, it is converted to heat.

Another result can be the creation of a charge of static electricity. For example rubbing a glass rod with a silk cloth will do this.
