Answer:

B. Solar energy

Explanation:

The water cycle is driven primarily by the energy from the sun. This solar energy drives the cycle by evaporating water from the oceans, lakes, rivers, and even the soil. Other water moves from plants to the atmosphere through the process of transpiration.

Two planets, Dean and Sam, orbit the Sun. They each have with circular orbits, but orbit at different distances from the Sun. De

lyudmila [28]

Answer:

The correct answer is Dean has a period greater than San

Explanation:

Kepler's third law is an application of Newton's second law where the force is the universal force of attraction for circular orbits, where it is obtained.

T² = (4π² / G M) r³

When applying this equation to our case, the planet with a greater orbit must have a greater period.

Consequently Dean must have a period greater than San which has the smallest orbit

The correct answer is Dean has a period greater than San

A conducting sphere of radius R1 carries a charge Q. Another conducting sphere has a radius R2 = 3 4 R1, but carries the same ch

Blizzard [7]

Answer:

The ratio of electric field is 16:9.

Explanation:

Given that,

Radius $R_{2}=\dfrac{3}{4}R_{1}$

Charge = Q

We know that,

The electric field is directly proportional to the charge and inversely proportional to the square of the distance.

In mathematically term,

$E=\dfrac{kQ}{R^2}$

Here, $E\propto\dfrac{1}{R^2}$

We need to calculate the ratio of electric field

Using formula of electric field

$\dfrac{E_{2}}{E_{1}}=\dfrac{R_{1}^2}{R_{2}^2}$

Put the value into the formula

$\dfrac{E_{2}}{E_{1}}=\dfrac{(4R_{1})^2}{(3R_{1})^2}$

$\dfrac{E_{2}}{E_{1}}=\dfrac{16}{9}$

Hence, The ratio of electric field is 16:9.

How do you solve <img src="https://tex.z-dn.net/?f=4x%5E%7B3%7D" id="TexFormula1" title="4x^{3}" alt="4x^{3}" align="absmiddle"

Vlad1618 [11]

$Hello$ $There!$

Here's a explanation!

Let's solve your equation step-by-step.

$4x^3=2x^-^1$

$4x^3=\frac{2}{x}$

Step 1: Multiply both sides by x.

$4x^4=2$

$\frac{4x^4}{4} =\frac{2}{4}$

(Divide both sides by 4).

$x^4=\frac{1}{2}$

$x=+(\frac{1}{2} )^(^\frac{1}{4} ^)$

Take the root.

ANSWER!

$x=0.840896$ $Or$ $x=-0.840896$

Hopefully, this helps you!!

When the core of a star like the sun uses up its supply of hydrogen for fusion, the core begins to ________?

daser333 [38]

Answer: shrink and heat

Stars similar to our Sun use hydrogen as fuel, creating helium in the process of <u>nuclear fusion. </u>

Now when the hydrogen is used up, the core of the star reaches such a temperature that begins to transform the <u>helium into carbon</u><u>.</u> That is, the core heats up more due to the continuous fusion reactions and shrinks because it will not have enough pressure to maintain its size.

Review. For a certain type of steel, stress is always proportional to strain with Young's modulus 20 × 10¹⁰ N/m² . The steel has

Nostrana [21]

The strain in the rod is $2.37\times 10^{-3}$

Given:

Young's modulus, Y = $20 \times 10^{10}\;N/m^{2}$

Steel density, $\rho = 7.86 \times 10^{3}\;kg/m^{3}$

Length of the rod, L = 80 cm = 0.800m

The speed of the wave in the rod is,

$v = \sqrt{\frac{Y}{\rho}} = \sqrt{\frac{20\times 10^{10}\ \mathrm{N/m^2}}{7.86\times 10^3\ \mathrm{kg/m^3}}} = 5044\ \mathrm{m/s}$

Hence the time taken by the wave to travel the end of the rod is,

$t=\frac{L}{v} = \frac{0.800\ \mathrm{m}}{5044\ \mathrm{m/s}} = 1.58\times 10^{-4}\ \mathrm{s}$

The velocity of the rod is, $v_r = 12.0\ \mathrm{m/s}$

The other end will keep moving after the front end hits the wall until the wave reaches the other end, given the period determined by the above problem.

As a result, before the wave reaches the end of the rod, it has traveled a distance of

$\Delta L = v_r t = (12.0\ \mathrm{m/s}) (1.58\times\ \mathrm{s}) = 1.90\times 10^{-3}\ \mathrm{m} = 1.90\ \mathrm{mm}$

The strain in the rod is given by,

$$\frac{\Delta L}{L} = \frac{1.90\times 10^{-3}\ \mathrm{m}}{0.800\ \mathrm{m}} = 2.37\times 10^{-3}$

Hence, the strain in the rod is $2.37\times 10^{-3}$ .

<h3>What is strain?</h3>

In terms of physics, strain is defined as the fractional modification of configuration.

A system's reaction to an applied stress is called a strain, according to 2. A force that loads a material results in a stress that leads to deformation. Formula for a strain

Change in configuration equals strain first arrangement

It is a dimensionless quantity that lacks a unit.

Change in object size / original object size is known as strain.

It is a quantity without units or dimensions.

Strain kind.

Object length change divided by starting object length equals longitudinal strain.

L/L stands for longitudinal strain.

Change in object volume divided by starting object volume equals longitudinal strain
