Answer:
Decrease
Explanation:
Working at a constant temperature when more pressure is exerted, the volume decreases.
This is known as Boyle's law.
According to Boyle's law;
"the volume of a fixed mass of a gas varies inversely as the pressure changes, if the temperature is constant".
Mathematically;
P₁V₁ = P₂V₂
P and V are pressure and volume
1 and 2 are initial and final states.
Answer:
6.78 km
Explanation:
Length of path due east = 4.3km
Length of path south = 2.48km
Unknown:
Distance covered = ?
Solution:
The distance covered is the total length of path from start to finish. It takes cognizance of the turns and every direction moved.
Unlike displacement which only considers the net direction from start to finish, distance sums up the total path.
So;
Distance = 4.3km + 2.48km = 6.78km
Answer:
Price elasticity of demand = 0.25
Explanation:
The detailed steps and appropriate derivation is as shown in the attached file.
Force due to gravity = 4080 x 9.81 = 40,025 N
Force of trailer parallel to slope = 40025 sin 14.5 = 10021 N (resolve horizontally)
<span>I used the acceleration of gravity as 9.81 m/s. If they want you to use 10 m/s, just switch it with the 9.81 in the first equation. Ignore the speed of the trailer. That is just to throw you off.</span>
Look it up it's really easy :) I don't really remember all of this. I haven't learned about this stuff since like 7th grade
