Prove that an electron cannot exist in the nucleus

Answers

Answer 1

Answer: We can say this is proved because electrons are having negative charges. If they lie inside the nucleus, they will be neutralised by the positive charges. Thus, the atom will have no charged particle and unstable. But an atom has both positive and negative charges.

Why evaporation are called surface phenomenon?

Answers

It is called surface phenomenon because when the molecules at the surface obtain kinetic energy because of heat and light absorption and overcome binding forces and then evaporate out so it is called surface phenomenon....

The water formed on the surface of the water evaporation loss (evaporation), consisting of plant transpiration water loss (transpiration) is called. Soil near the plant and the resulting water loss is called by evapotranspiration.

The unit for measuring electric power is the A. volt.
B. ampere.
C. watt.
D. ohm.

Answers

Final answer:

The unit for measuring electric power is watt. This is the rate at which electrical energy is transferred. Other units like volts, amperes, and ohms are used to measure electrical potential difference, current, and resistance respectively.

Explanation:

The unit for measuring electric power is the watt (C). Electric power is the rate at which electrical energy is transferred by an electric circuit. Volts (A) are the units used to measure electrical potential difference, amperes (B) measure electrical current, and ohms (D) are used to measure electrical resistance. Therefore, if you are looking to measure electric power, your correct unit will be the watt. An example would be that a light bulb might use 60 watts of power.

Final answer:

The unit for measuring electric power is the watts. It's calculated as one joule per second and, electrically, it's the product of voltage and current. Other units such as volt, ampere, and ohm measure electric potential difference, current, and resistance respectively.

Explanation:

The unit for measuring electric power is the watts. The watt is a unit of power that is defined as one joule per second. In terms of electrical power, it is calculated by multiplying the voltage (measured in volts) by the current (measured in amperes). Other units such as volt and ampere are related to electrical phenomena but they do not measure power. The volt measures electric potential difference or electric pressure whereas the ampere measures electric current. The ohm on the other hand is a measure of electrical resistance.

A series circuit contains four light bulbs. The switch is opened and one of the bulbs is removed, but not replaced. Then the switch is closed again. What would you expect to see?A) All three remaining light bulbs will be on.
B) None of the remaining light bulbs will be on.
C) Only the bulb closest to the switch will be on.
D) All three remaining light bulbs will be brighter than before.

Answers

The correct answer is option B) None of the remaining light bulbs will be on.

What will happen if one light bulb is removed from a series circuit?

In a series connection when a bulb is removed, it will be creating a open circuit. Since the circuit is series and is open at a point current will not flow and hence the other bulb will not glow.

Why did the series circuit stop working when one of the light bulbs was removed?

That's because the basic requirement for the circuit to operate a continuous, closed-loop path is no longer met. This is the main disadvantage of a series circuit. If any one of the light bulbs or loads burns out or is removed, the entire circuit stops operating.

for series circuit, components are in the same path. removing component, the path is broken. so without replacing the bulb, current could not flow -- open circuit. all bulbs are dead.

A force of 450 N accelerates a box across a frictionless surface at a rate of 15 m/s2. Find the mass of the box?A) 30 N

B) 30 kg

C) 6,750 N

D) 6,750 kg

Answers

Second Law of Newton: Net force equals mass times acceleration

F = m*a => m = F/a

m = 450N / 15 m/s^2 = 30 kg

Answer: option B) 30 kg

It would be: m= F/a = 450 N / 15 m/s^2 = 30 Kg
