Answer:
Pressure Increases
Explanation:
When the temperature of a gas is increased inside a container then the pressure of the gas inside the container increases.
This can be deduced by the Ideal Gas law equation:
where:
P = pressure of the gas
V = volume of the gas
n = no. of moles of gas
R = universal gas constant
temperature of the gas
So,
hence the pressure of the gas will increase while the temperature is increased at a constant volume
Answer:
Each student gets 4 green stickers and 5 purple stickers or a total of 9 stickers.
Explanation:
The greatest common divisor (GCD) of two or more natural numbers or integers (not numbers with decimals) is the largest number that divides them. In other words, the Greatest Common Divisor is the greatest of the common divisors of several numbers. To calculate it, each of them is decomposed into prime factors. The GCD is the result of multiplying the factors that are repeated in all the decompositions, affected by the smallest exponent.
In the event that no factor is repeated, the GCD of those numbers is 1, and the numbers are said to be "prime to each other."
In this case, the decomposition of 12 and 15 is:
12 = 2²*3.
15=3*5
So the GCD between 12 and 15 is 3
Now, to calculate how many green and purple stickers each student receives, you simply divide the amount of each sticker color by 3.
12÷3= 4
15÷3= 5
So, <u><em>each student gets 4 green stickers and 5 purple stickers or a total of 9 stickers.</em></u>

Answer:
a) 3.242
b) 1291.178 KJ
c) 3.59 cents
Explanation:
a) First all the temperature units should be in Kelvin. -30°C + 273.15 = 243.15K and 45°C + 273.15 = 318.15K. Coefficient of performance for refrigerator is COP = TL/(TH-TL) where TL is Lower Temperature and TH is the Higher Temperature. COP = 243.15/(318.15-243.15) = 3.242
b) COP = Cooling Effect/Work Input. Cooling Effect (or Desired Output) is 4186 kJ.
So Work Input = Cooling Effect/COP = 4186KJ/3.242= 1291.178 KJ
c) 3.6 MJ (3600kJ) is for 10 cents, using ratio for cost: energy used
3.59 cents
Answer
given,
initially rotating speed = 130 rad/s
final rotating speed = 0 rad/s
constant acceleration = 3 rad/s²
a) using equation of rotating acceleration
3 t = 130
t = 43.33 s
time does the disk take to stop is equal to 43.33 s
b) again using equation of rotation
angle does the disk rotate during that time is equal to 2817 rad
