Eyepiece is magnifies the image so you can see it clearly. Compare and contrast how images form in a refracting telescope reflection telescope and microscope. ...Refracting telescope is uses two lenses to locate somethings. Reflecting telescope uses a large concave mirror to gather light.

Sorry if this answer is a bit late...
We know that the volume of the water is 0.5 cube meters.
The density of water is 1.000 g/m^3 (that's the real density of water... maybe typos?)
The density of ice is 0.900 g/m^3 (that's the approximate density of ice)
First, let's multiply the volume of water by the density of the water to get the mass, since we know that the mass does not change with the ice gets frozen.
0.5 * 1.000 = 0.500 g
Now, let's divide that by the density of ice to get the volume of the ice.
0.500 / 0.900 = 5/9 cube meters
≈ 0.556 cube meters.
The volume of the ice is 5/9 or 0.556 cube meters.
Have an awesome day! :)
False it’s the unit of force
ΔH<span> for the reaction = [sum of heat of formation for products] - [sum of heat of formation for reactants]
-6534 = [(12)(-393.5) + (6)(-285.8)] - (2X)
-6534 = [(-4722) + (-1714.8)] - 2X
-6534 = -6436.8 - 2X
-6534 + 6436.8 = -2X
-</span>97.2 = -2X<span>
then, divide each side by two to cancel out the numerical coefficient.
x = +48.6 kJ, which is the heat of formation for benzene.</span>
Answer:
Rate at which current flows is measured in amperes
Explanation:
The rate of flow of electrons constitutes the current. The electrons flow from lower electric potential to higher electric potential. When there is no potential difference then no electron will flow. The direction of the current and the electron are in opposite direction.
The direction of electron from the negative terminal to the positive terminal. The direction of current is from the positive terminal to the negative terminal.The current is measured in ampere.
The expression for current and the charge is as;
Here, q is the charge, t is the time taken and I is the current.
According to the given problem, Jodi made a list about electric current to help her study for a test. He described that electrons move from areas of low to high electric potential, voltage causes current to flow and movement of electrons is continuous in a current.
But he did error. It should be "rate at which charges flow" instead of rate at which current flow.
Therefore, the option (4) is correct.
