Answer:

Option (B)

Explanation:

The latent heat is often defined as the amount of temperature that is needed in the conversion of a phase, such as from solid to liquid (or gas) or from liquid to gas, and during this entire process, the temperature remains constant.

This latent heat plays an important role in generating intensive thunderstorms as well as hurricanes because it acts as a source of energy.

There are two types of latent heat and they are as follows-

(1) Latent heat of fusion- This involves a phase change from solid to liquid.

(2) Latent heat of vaporization- This involves a phase transformation from liquid to gas.

Thus, the correct answer is option (B).

A particle with charge Q is on the y axis a distance a from the origin and a particle with charge q is on the x axis a distance

Natalka [10]

Answer:

Explanation:

Force on q due to Q

= k Qq / ( a² + d²)

x component

= k Qq / ( a² + d²) x d /√ ( a² + d²)

F = kQq d/ ( a² + d²)³/²

differentiating F with respect to d

dF / Dd = kQq [ d. -3/2 ( a² + d²)⁻⁵/² 2d + ( a² + d²)⁻³/²]=0 for maximum F

- 3d² / ( a² + d²) + 1 = 0

a² + d² = 3 d²

a² = 2d²

d = a / √2

if the moon is 238,000 miles from earth, convert this distance to meters and leave your answer in scientific notation.

Softa [21]

The result of the value conversion is 382,942,000 meters and it can be written by scientific notation as $\sf{\bold{3.83 \times 10^8 \: meters}}$

<h2>Introduction </h2>

Hi ! I'm Deva from Brainly Indonesia. Here I will help you convert between units and convert it to scientific notation.

<h3>International Standard Unit</h3>

In the world of physics, we know a system called International Standard units, so that the non-standard form of units (which are agreed upon by several countries or people only), must be converted to this international standard.

<h3>Scientific Notation</h3>

Scientific notation is the notation used to simplify the mention of too long zeros as integers or decimal number. Scientific notation is denoted by:

$\boxed{\sf{\bold{x \cdot 10^n}}}$

With the following condition :

x = any number starting from 1 and less than 10 and can be decimal.
n = any number both positive and negative integers.

<h2>Problem Solving</h2>

We know that :

1 mile ≈ 1.609 kilometers ≈ 1,609 meters
The distance >> 238,000 miles.

What was asked :

Distance = ... meters
Scientific notation = ... ?

Step by step :

Distance = d

$\sf{d = 238,000 \times 1,609}$

$\boxed{\sf{d = 382,942,000 \: meters}}$

Scientific Notation

The result states the number in the hundreds of millions. The number hundreds of millions always has a power of 8 ( $\sf{10^8}$ ). So, we convert 382.942,000 >> 3.82942000 and because the last three zeros can be omitted.

The scientific notation become :

$\boxed{\sf{Distance \: = 3.83 \times 10^8 \: meters}}$
