Find the equation of the line passing through the points (2, 1) and (5, 10).​
Vedmedyk [2.9K]

The equation : y=3x-5

<h3>Further explanation </h3>

Straight-line equations are mathematical equations that are described in the plane of cartesian coordinates

General formula

y-y1 = m(x-x1)

or

y = mx + c

Where

m = straight-line gradient which is the slope of the line

x1, y1 = the Cartesian coordinate that is crossed by the line

c = constant

The formula for a gradient (m) between 2 points in a line

m = Δy / Δx

  • Gradient

\tt \dfrac{10-1}{5-2}=3

  • Equation

\tt y-1=3(x-2)\\\\y-1=3x-6\\\\y=3x-5

The volume of a gas filled balloon is 22L at 313K and 1.5 atm. What would the volume be at 273K and 1 atm?
avanturin [10]
<h3></h3>

From the calculations and the statement of the general gas equation, the volume of the gas becomes 28.8 L

<h3>What are gas laws?</h3>

The gas laws are used to show the relationship between the variables in problems that has to do with gases.

In this case, we have to apply the general gas law as follows;

P1V1/T1 = P2V2/T2

P1V1T2 = P2V2T1

V2 =   * 22L *  1.5 atm * 273K/313K * 1 atm

V2 = 28.8 L

If the kinetic and potential energy in a system are equal, then the potential energy increases. What happens as a result?
ZanzabumX [31]

Answer: As a result an increase in kinetic energy also happens.

Explanation:

Potential energy is the energy occupied by an object or substance due to its position.

Kinetic energy is the energy occupied by an object of substance due to its motion.

If the kinetic and potential energy in a system are equal and then an increase in potential energy will occur.

As a  result, there will also occur an increase in kinetic energy also.

Thus, we can conclude that as a result an increase in kinetic energy also happens.
