What is the charge of the nucleus of an oxygen atom?
0
–2
+8
+16

Answers

Answer 1
Answer: The charge will be +8.

How? The atomic number of oxygen is 8 that means that it has 8 protons in it's nucleus. Since each proton has +1 charge on it 8 would have +8.
Answer 2
Answer:

Answer:

3

Explanation:

Because the atomic number of oxygen is 8 therefore it will be +8

If two glasses of water are at the same temperature, the average kinetic energy of the particles of water in each glass is the same. Please select the best answer from the choices provided T F

Answers

Answer: The correct answer is True.

Explanation:

Average kinetic energy of the particles is defined as the average of the kinetic energies of the particles present in a medium. It is the measure of temperature of the medium.

Mathematically,

K=(3)/(2)(RT)/(N_A)

where,

K = kinetic energy

T = Temperature

\text{Kinetic energy}\propto \text{Temperature}

As, kinetic energy of the particles is directly proportional to the temperature. Increase in temperature will result in the increase in the kinetic energy and vice-versa.

We are given, that the temperature of the two glasses are same, so the average kinetic energy of the particles will also remain same.

Hence, the correct answer is True.

The statement ‘If two glasses of water are at the same temperature, the average kinetic energy of the particles of water in each glass is the same’ is true. This is because temperature is directly proportional with the kinetic energy of the molecules. If there is no change in temperature, there would not be kinetic movement of the molecules.

If you are in a spaceship that is sitting on the surface of a planet, you feel your weight. How does this compare to the weight you feel in an accelerating spacecraft?

Answers

Answer:

You will feel more weight if it is accelerating out of the planet.

You will feel less weight if it is accelerating towards the planet.

Explanation:

The weight that you are observing or feeling is basically due to the change in acceleration of your fall or rising up in the spaceship. When the acceleration is stationary on the surface, you experience your normal weight due to the gravitational acceleration of that planet.

When the spaceship accelerates above or out of the planet you experience acceleration more than the acceleration of gravity hence more weight.

When the spaceship accelerates towards the planet you experience acceleration less than the acceleration of gravity hence less weight.

If the spaceship is free falling at the gravitational acceleration you experience a zero weight

. If the centripetal and thus frictional force between the tires and the roadbed of a car moving in a circularpath were reduced, what would happen?

Answers

In this particular case, where car is moving through curvature, so it is moving in circular motion, force acting on car is centripetal force which holds car not to fly out. Centripetal force is always pointed in the middle of circle. Here frictional force has role of centripetal force. If frictional force is to weak, car would fly out of curvutare.

Which of the following is true about light with a single wavelength?1) It can be refracted
II) It cannot be dispersed
III) It can be reflected *

Answers

Answer:

It can be refracted

Explanation:

When a single wavelength wave which is known as a monochromatic light is passed from one transparent medium to the other, it can refract. This refraction can only be seen if the light enter the medium at some angle.
