I don't know what your options are, but heat moves from the sun moves in 3 ways: radiation, conduction, and convection. I hope this helps at least a little

Answer: Radiation

Explanation:

There are three modes of heat transfer:

<u>Conduction: </u>Heat transfers from hotter body to colder one via conduction when they are placed in contact with each other. The molecules vibrate and transfer heat.

<u>Convection: </u>Heat transfers in fluids via convection. The heat is carried by bulk motion of fluid.

Radiation: Heat transfer through space takes place via radiation. The electromagnetic waves carry the energy from the Sun and moves through space. This mode does not depend on the medium. The electromagnetic waves carry the energy and travel at the speed of light.

select the correct scientific notation form of this numeral 541 5 * 10^2 5.4 * 10^2 5.4 * 10^2 5.0 * 10^2

USPshnik [31]

To find the scientific notation, you need to divide at the decimal by the power of 10. So since there are 2 powers of 10, what you want to do is move the decimal 2 places to the left which will give you: .054

If a flea can jump straight up to a height of 0.410 m , what is its initial speed as it leaves the ground?

aivan3 [116]

Initial velocity = $v_0$

acceleration in the downward direction = -9.8 $\frac {m}{s^2}$

Final velocity at the highest point = 0

Maximum height reached = 0.410 m

Now, Using third equation of motion:

$\(v^2 = {v_0}^{2} + 2aH$

$\(0^2 = {v_0}^{2} - 2 \times 9.8 \times 0.410$

${v_0}^{2} = 2 \times 9.8 \times 0.410$

$v_0 = 2.834 \frac {m}{s}$

Speed with which the flea jumps = $2.834 \frac {m}{s}$

a solid sphere has a radious of 5 cm and a mass of 350 grams. what is its average density in g/cm^3? brainly

Rom4ik [11]

Hi!
So FIRST the equation to find the volume of a sphere is: 4/3 pi R^3

Then this filled in would be : 4/3 (pi(5^3))
Which would get you: 523.6 (rounded answer).

So now we solve for density using D=M/V

So: 350g/ 523.6 cm ^3 = .67 g/cm^3 (rounded)

Hope this helps- please name brainliest- if you have any questions don’t hesitate to ask!
