Answer:
Thermodynamics is usually defined as a branch of physics that deals with the study of the heat and various form of energy, and their interaction between the.
The first law says that heat appears as energy, and it cannot be produced and also cannot be demolished. It can only change from one form to another. This signifies that the total amount of energy present in the universe remains constant.
This first law can be mathematically represented as:
ΔU = Q - W
where ΔU = Changes occurring in the internal energy
Q = amount of heat added to the system
W = Amount of work done by the system
Answer:
boron and neon.
Explanation:
two element compounds are usually ionic when one element is a metal and the other is a non-metal. boron is a metal, whereas neon is a non-metal. i might be wrong but hope it helps.
Answer:
<em>The cantaloupe has a speed of 117.6 m/s</em>
Explanation:
<u>Free Fall Motion</u>
It occurs when an object falls under the sole influence of gravity. Any object that is being acted upon solely by the force of gravity is said to be in a state of free fall. Free-falling objects do not face air resistance.
If an object is dropped from rest in a free-falling motion, it falls with a constant acceleration called the acceleration of gravity, which value is
.
The final velocity of a free-falling object after a time t is given by:
vf=g.t
The cantaloupe has been dropped from rest. We are required to find the speed after t=12 seconds.
Calculate the final speed:
vf=9.8 * 12 = 117.6 m/s
The cantaloupe has a speed of 117.6 m/s
True. as the light is diffracted it is diffused and must be corrected for
X=ut+0.5at²
1000 = 63.3u + 0.5 * 0.0323 * 63.3²
u = (1000 - 0.1615*63.3²)/63.3
u = 5.57 m/s
i don't even know if this is correct
