Answer:
theres no question lol
Explanation:
Chocolate is a preparation of roasted and ground cacao seeds that is made in the form of a liquid, paste, or in a block, which may also be used as a flavoring ingredient in other foods!!!!
To solve this problem it is necessary to apply the kinematic equations of motion for speed and distance, as well as the concepts related to kinetic energy.
The change in the height of a body subject to gravity is given by
Where
h = Height
g =Gravity
t = time
Replacing with our values we have that the time is
From speed as a function of change between acceleration and time we have then that after 2.6 seconds the speed would be
The kinetic energy would be given by
Therefore the kinetic energy after 2.6s is 1070.16J
Answer:
The thermal energy is carried by electromagnetic waves
Explanation:
There are three types of transfer of heat (thermal energy):
- Conduction: conduction occurs when two objects/two substances are in contact with each other. The heat is transferred from the hotter object to the colder object by the collisions between the molecules of the two mediums.
- Convection: convection occurs when a fluid is heated by an external source of heat. The part of the fluid closer to the heat source gets warmer, therefore it becomes less dense and it rises, and it is replaced by the colder part of the fluid, which is colder. Then, this part of fluid is heated as well, so it gets warmer, it rises, etc.. in a cycle.
- Radiation: radiation occurs when thermal energy is carried by electromagnetic waves. Since electromagnetic waves do not need a medium to propagate, this is the only method of heat transfer that can occur through a vacuum (so, in space as well).
Indeed, the Sun emits a lot of electromagnetic radiation, which travels through space and eventually reaches the Earth, heating it.

Answer:
58.8NM-²
Explanation:
The pressure is the product of density,depth(height) and acceleration due to gravity
here the density of water is 1gm-³ it a constant so it not given
pressure= 6×9.8×1
pressure = 58.8NM-²
