Answer:
Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.
Explanation
Answer:
8m/s^2
Explanation:
<em>Acceleration</em><em>=</em><em>initial </em><em>velocity</em><em>-final </em><em>velocity</em><em>/</em><em>time</em>
<em>initial</em><em> </em><em>velocity(</em><em>u)</em><em> </em><em>is </em><em>3</em><em>2</em><em> </em><em>final </em><em>velocity</em><em> (</em><em>v)</em><em> </em><em>is </em><em>9</em><em>6</em>
<em>therefore</em>
<em>a=</em><em>9</em><em>6</em><em>-</em><em>3</em><em>2</em><em>/</em><em>8</em>
<em>a=</em><em>8</em><em>m</em><em>/</em><em>s </em><em>squared</em>

Geothermal power plants use the renewable resource of heat from within the Earth to generate electricity.
Explanation:
The correct statement is that geothermal power plants use the renewable resource of heat from within the Earth to generate electricity.
Geothermal energy is heat energy from within the earth.
- Geothermal energy is not available everywhere on the earth. It is restricted to certain geologic terrains.
- It is a renewable source of energy whose usage cannot be depleted at our current rate of consumption.
- This heat is used to produce electricity in areas where they occur.

Answer:
6.7 kg
Explanation:
V = 5000 L = 5000 x 10^-3 m^3 = 5 m^3
T = 0.2 degree C = 273.2 K
P = 1.04 atm = 1.04 x 1.01 x 10^5 Pa = 1.0504 x 10^5 Pa
R = 8.314 in SI system of units
Use the ideal gas equation. Let n be the moles of air occupied in the lungs of whale.
P V = n R T
n = P V / R T
n = (1.0504 x 10^5 x 5) / (8.314 x 273.2) = 231.22
the mass of one mole of air is 28.98 g
So, the mass of 231.22 moles of air = 231.22 x 28.98 = 6700 .88 g = 6.7 kg
The easiest way to work this out is to think of the amount of decay as a percentage. so in 12 years its down to 50% another 12 years its down to 25%, another 12 years its 11.5 %.
<span>for a 20 gram sample to decay by half will still be 12 years no matter how many grams one has.</span>
