Answer:
See explanation below.
Explanation:
The internal energy (kinetic energy) of the milk particles increases thus warming the milk up, while the internal energy of the coffee particles reduce their initial average speed as they are imparting energy to the slow milk particles.
H3 in reaction: NH3 + H2O→NH4 + OH-
<span>The NH3 has gained an H - it is a base

The potential energy is defined as the energy is contained in the body due to the height over the surface of the earth and it is calculated from the equation
<em>where:</em>
- PE: the potential energy in Joules.
- m: the mass of the body in kg.
- g: the acceleration due to the gravity in m/
- h: the height of the body over the earth in meters.
<em>in our problem:</em>
Answer:
F=507.7N
Explanation:
According to Newton's second law:
in this case, the football players need to drag the coach at a constant velocity, thus means with no acceleration, so:
there are 20 degrees between the two ropes that means each player exerts a force 10 degrees from the zero reference.
