Physics
1 answer:
oee [108]3 years ago
4 0

Answer: Option A: a taut guitar string

Explanation:

The sum total of kinetic energy and potential energy is known as mechanical energy. The energy possessed by a body due to virtue of its position is known as mechanical potential energy. The energy possessed by a body due to virtue of its motion is known as motion is known as kinetic energy.

A taut guitar string possesses only mechanical potential energy.

The rest of the examples have either kinetic energy or combination of potential energy plus kinetic energy.

Hence, option A is correct.

Answer:

cation, anion

Explanation:

Binary Ionic Compounds- Binary means 2, ionic relates to charges. Therefore binary ionic compounds have TWO elements, with charges that cancel eachother out. The cation (or positive charge) goes before the anion (or negative charge)

example:

NaCl

Na^+1

Cl^-1

Sodium Chloride

Learning Goal: To understand the concepts explaining the operation of transformers.
Alex

Answer:

Part a)

ZERO

Part b)

N = 10 turns

Explanation:

Part a)

As we know that transformer is used to change the input voltage into required output voltage

Here this input and output is considered only when it will change with time as the whole concept is based upon Faraday's law where we need to change the flux with time.

So if we have input Source is DC source then output voltage will be zero as there is no flux change

Part b)

As we know by the principle of transformer

\frac{V_1}{V_2} = \frac{N_1}{N_2}

\frac{500}{25} = \frac{200}{N_2}

N_2 = 10

so total number of turns in secondary coil must be 10

Describe the conditions necessary for sublimation to occur.
lozanna [386]
<span>To answer this question with specific values, you would need a phase diagram for the substance in question. In more general terms, the pressure needs to be lower than the pressure of the triple point, the substance must be present in its solid state, and the temperature must rise high enough to produce a gas.</span>
