Answer:
34.5
Step-by-step explanation:
17 + 70/x when x = 14.
substitute x for 14
17 + 70/4
17 + 17.5
34.5
Answer:
Kinetic theory explains why the volume of a container must expand when the temperature of the gas inside increases in order for the pressure to remain constant.
Step-by-step explanation:
Charles' law: for a fixed mass of gas at constant pressure the volume is directly proportional to the temperature.
Analysis of a gas when its temperature increases according to kinetic theory:
The temperature has increased therefore the molecules have more kinetic energy, so they move with a greater velocity.¹
If the container's dimensions do not change the molecules will travel across the container between the walls in less time (because they are moving faster and covering the same distance between the container walls). This will increase the rate of collisions, which would increase the pressure.²
But if the dimensions of the container increased then the molecules would cover a larger distance faster thereby maintaining a constant rate of collisions. This would maintain a constant pressure.

Answer:
The net cost of the photocopier before january 1 is <u>$1350.</u>
Step-by-step explanation:
Given:
The manufacturer offers a $125 rebate on photocopiers purchases before january 1.
Now, to find the net cost of $1,475 photocopier before january 1.
Amount of rebate before January 1 = $125.
Cost of photocopier = $1,475.
So, to get the net cost of $1475 photocopier before january 1 we subtract the rebate from it:
Therefore, the net cost of the photocopier before january 1 is $1350.
