From the definition of the first Law of thermodynamics we know that heat flows from the hottest object to the coldest. What has a refrigerator inside is a refrigerant that is traveling through some heat exchangers, driven by pumps and that allows the exchange of heat between a 'Hot' tank and then transport it to a certain place, eject it and return to extract more heat. In this way the refrigerant removes heat from a hot region to a cold region and heat enters said hot region. Since the heat extracted is greater than that of the medium, the heat from the inside flows outward.
The correct answer is B.
The bus and the truck have the same velocity.
Also, Valerie and Owen have the same velocity.
<span>example shows that electromagnetic waves can travel without moving through a specific material is
</span>light passing through a vacuum tube
because it shows that there is no medium
so correct option from above is D
hope it helps
I need help with my homework it’s due tomorrow and I feel like I failed can u help me bro
Answer:
K.E = 156.25 Joules.
Explanation:
Given the following data;
Mass = 0.5kg
Velocity = 25 m/s
To find the kinetic energy;
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
Where;
K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents velocity measured in metres per seconds square.
Substituting into the equation, we have;
K.E = 156.25 Joules.
