Power plants can be powered by fossil fuels, such as coal or natural gas, or nuclear power to produce steam to turn turbines to
Naddika [18.5K]
<span>Nuclear energy is cleaner while generating electricity. Nuclear fission provides energy without releasing greenhouse gases such as carbon dioxide. However, nuclear power plants generate significant amounts of radioactive waste.  That is why we should not choose nuclear energy over fossil fuel power plants.</span>

Two sticks are suspended on silk thread, electrified by charges of opposite sign. Is there a magnetic field around them? An elec
IRINA_888 [86]

ANSWER and EXPLANATION

We want to identify if there will be an electric field and a magnetic field around the two sticks electrified by charges of opposite signs.

An electric field is a physical field that surrounds electrically charged particles and exerts a force on other charged particles in the surrounding.

This implies that the presence of electric charges on both sticks generates electric fields on them. Since the two charges are opposite, the electric force acting on them will be attractive.

Hence, there is an electric field.

A stationary charged object produces an electric field, as explained above, but will only produce a magnetic field if there is a motion of the object.

Hence, except the two sticks are caused to move, there will be no magnetic field around them.

An object is dropped from a height of 75.0 m above ground level. (a) determine the distance traveled during the first second.
barxatty [35]

The relevant formula we can use in this case would be:

h = v0 t + 0.5 g t^2

where,

h = height or distance travelled

v0 = initial velocity = 0 since it was dropped

t = time = 1 seconds

g = 9.8 m/s^2

 

So calculating for height h:

h = 0 + 0.5 * 9.8 m/s^2 * (1 s)^2

<span>h = 4.9 meters</span>

What do the atoms of elements in the same group have in common? A. They have the same atomic numbers. B. They have the same aver
sergiy2304 [10]

Answer:

A. They have the same atomic numbers.

Explanation:

Elements are defined based on the atomic number, which is the number of protons in the nucleus: this means that atoms of the same element have always the same number of protons in their nuclei (and so, always the same atomic number).

The other choices are wrong because:

B. They have the same average atomic masses. --> this is false for isotopes, which are atoms of the same element having a different number of neutrons. Since the atomic mass is calculated from the sum of the masses of protons and neutrons in the nucleus, two isotopes of the same element have different atomic mass

C. They have the same number of electron shells. --> this can be false when an atom of an element loses/gains an electron, becoming an ion: in that case, the number of electron shells can change,  since the number of electrons has changed.

D. They have the same number of electrons in their outermost shells. --> this is also false in case one of the atoms is an ion, since the number of electrons is different.
