Continental air masses are characterized by dry air near the surface while maritime air masses are moist. Polar air masses are characterized by cold air near the surface while tropical air masses are warm or hot. ... Maritime polar (mP) air masses are cool, moist, and unstable.
Answer:
She is not getting a good deal.
Explanation:
The equation that relates heat with mass, specific heat and temperature change of an object is 
.
Always convert temperature to Kelvin, although in our case it's not necessary because the 
will be the same, and we will leave the mass in grams because we will be getting 
units for specific heat, which we can compare to the one given for gold.
We then calculate the specific heat of the object in question:
Which shows it's not gold.
Answer:
In a closed-loop system, matter is used to generate energy, and the energy generated is used to produce matter, and the cycle goes on without end.
Explanation:
A closed-loop system is one in which materials or energy is recycled without end through a production cycle. This means that a raw material is used to produce a finished product, and the finished product at the end of its use cycle is converted back and used as a raw material to produce more of it again. Energy and matter can also be cycled in the same way in an energy and matter closed-loop system, converting matter to energy, and the energy is put back into the production of more of the matter.

Kinetic energy is energy possess by an object due to it motion.
Mass 1; m = 500 Kg Velocity 1; V = 40 m/s
Mass 2; m = 1000 Kg Velocity 2; V = 20 m/s
Formula: K.E = 1/2mv²
For Mass 1 K.E = 1/2(500 Kg)(40 m/s)² = 400, 000 J
For Mass 2 K.E = 1/2(1000 Kg)(20 m/s)² = 200,000 J
This solution shows that a larger velocity will have a greater kinetic energy.
