Answer:
Chemical potential energy is the energy stored in the chemical bonds of a substance. The various chemicals that make up gasoline contain a large amount of chemical potential energy that is released when the gasoline is burned in a controlled way in the engine of the car. The release of that energy does two things
Explanation:
The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.
Answer:
In the visible spectrum of light, the color of the light depends on the frequency. The visible spectrum is always the same for a rainbow or the separated light from a prism. The order of colors is red, orange, yellow, green, blue, indigo, and violet.
Explanation:
It is the intervention of citizens in decision-making regarding the management of resources and actions that have an impact on the development of their communities.
<span>Air pressure is gravity pulling down on air molecules. Like us,
air has also mass and the pressure is brought down by the earth’s gravity
causing an increase in weight exerted on you as you descend lower into the
atmosphere. So, as you enter into the other layers of atmosphere above the troposphere,
the air pressure starts to decrease. <span>Below the atmosphere is the hydrosphere. This is
where all liquid forms are located. And since the seawater has a greater mass
than air, it has the greatest pressure. The answer is true.</span></span>

h = 0 when the ball hit the ground, so
<span>0 = rt - 16t^2 </span>
<span>Since r = 32, </span>
<span>0= 32t - 16t^2 </span>
<span>16t(2 - t) = 0 </span>
<span>t = 0 or 2 </span>
<span>At t=0, h=0 but the ball hasn't left the ground yet. </span>
<span>Thus, the answer is 2.</span>
