Answer:

The correct answer is a = potential

Explanation:

Hello! Let's solve this!

Water on top of a waterfall has accumulated potential energy. This energy has the bodies at rest and is due to its mass, its height and the acceleration of gravity. Once the water drop begins, this potential energy becomes kinetic energy.

The correct answer is a = potential

Which compound is used to make asphalt?
Masteriza [31]
Asphalt is a biproduct of making gasoline, diesel, kerosene, jet fuel, all from crude oil pumped from the ground. Asphalt is the garbage or waste that comes out the bottom of the process of distilling those products. They heat the thick oily-sooty gunky asphalt and mix it with rock or sand and make roads out of it. So the compound would be the long hydrocarbon chains.

An unknown metal has a mass of 86.8 g. When 5040 J of heat are added to the sample, the sample temperature changes by 64.7 ∘ C .
grandymaker [24]

Answer: The specific heat of the unknown metal is 0.897J/g^0C

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

Q=m\times c\times \Delta T

Q = Heat absorbed=5040 Joules

m= mass of substance = 86.8 g

c = specific heat capacity = ?

Initial temperature of the water = T_i

Final temperature of the water = T_f

Change in temperature ,\Delta T=T_f-T_i=(64.7)^0C

Putting in the values, we get:

5040=86.8\times c\times 64.7^0C

c=0.897J/g^0C

The specific heat of the unknown metal is 0.897J/g^0C

How many molecules are there in 45.0 grams of CH ?
Sonbull [250]

Answer:

There are 1.8021 ⋅ 1024 molecules of CH4 in 48 grams of CH4. To answer this question, you must understand how to convert grams of a molecule into the number of molecules. To do this, you have to utilize the concepts of moles and molar mass. A mole is just a unit of measurement. Avogadro's number is equal to 6.022 ⋅1023 molecules/mole. i think please dont complain to me if its wrong im sorry
