<span>The ball will be subject to potential and kinetic energy at this point in time as it is still rising away from the ground and not yet subject to the pull of gravitational force. The potential energy will account for the forces occurring due to change in relative position of the ball during its flight while kinetic energy will account for the energy derived by its motion.</span>
It allows people in different places and different countries to use the same units, avoid mistakes and understand each other more easily. The common base 10 of all units makes it easier and has more accurate calculations that are made without cumbersome conversion factors.
Answer:
Comets develop a fuzzy, cloud-like shell called a coma, as well as a tail.
Explanation:
This feature of a comet develops when the celestial body passes close to a star such as the sun. The ice around the nucleus of the comet sublimates forming the coma around the comment (when hit by light photons as observed from the earth). The tails are also formed by the ice being pushed a bit behind the comet by light pressure.
Answer:
THE AMOUNT OF HEAT ABSORBED DURING THE REACTION IS 151.64 JOULES
Explanation:
Mass = 12.58 g
Specific heat of CaCO3 = 0.82 J/g K
Change in temperature = 38.3 C - 23.6 C = 14.7 C
How many joules of heat are absorbed?
Heat of a reaction is the amount of heat absorbed or evolved when a gram of a sample is raised by 1 C.
Heat = mass * specific heat * change in temperature
Heat = 12.58 * 0.82 * 14.7
Heat = 151.64 J
The amount of joules absorbed during this reaction is 151.64 J.
