Answer:

See the explanation below.

Explanation:

This analysis can be easily deduced by means of Newton's second law which tells us that the sum of the forces or the total force on a body is equal to the product of mass by acceleration.

∑F = m*a

where:

F = total force [N]

m = mass [kg]

a = acceleration [m/s²]

We must clear the acceleration value.

$a=\frac{F}{m}$

We see that the term of the mass is in the denominator, so that if the value of the mass is increased the acceleration decreases, since they are inversely proportional.

Much power does a 10 Ohm bulb have in a series circuit with a battery of 12V and nothing else in the the circuit?

Sedaia [141]

Answer:

it will be d) 14.4W

Explanation:

potential difference (v) = 12 volts

resistance (r) = 10 ohms

now, we know

=》

$power = \frac{v {}^{2} }{r}$

=》

$power \: = \frac{12 {}^{2} }{10}$

=》

$power = \frac{144}{10}$

=》

$power = 14.4 \: watt$

How does the Earth release energy back into the atmosphere?

JulsSmile [24]

In general, the Earth releases energy back to the atmosphere through reflection, evaporation, and radiation. The Earth gets energy from the sunlight, part of which it absorbs, while part it reflects backwards, thus giving energy to the atmosphere. Also, the heating up of the Earth by the absorbed sunlight, radiates back in the lower layers of the atmosphere, again giving back energy to it. The water vapor is another way in which the Earth gives back energy tot he atmosphere as through the evaporation, the water vapor gets into the lower parts of the atmosphere and gives energy to it.

Crystals can have _____ bonds between their atoms.

Dmitry_Shevchenko [17]

<h3>Answer;</h3>

All types of

Crystals can have all types of bonds between their atoms.

<h3>Explanation;</h3>

Crystals are solid materials which contains atoms, molecules or ions that are arranged in a complex structure forming a crystal lattice.
Crystals may have all types of bonds, these includes; ionic bonds, formed as a result of transfer between a metallic bond and a non-metal atom, Covalent bond, formed as a result of sharing electrons between non metal atoms, hydrogen bonds, metallic bonds Van der Waals bonds, etc.
