According to Charles law, if pressure remains constant, volume varies directly with temperature. so we can infer that :
[tex] \qquad\sf{\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}} [/tex]
So, we can use this formula to find out the final temperature of the gas ~
Note : Take temperature in Kelvin ( 100°C = 373 K )
[tex]\qquad \sf \dashrightarrow \: \dfrac{3}{373} = \dfrac{6}{x} [/tex]
[tex]\qquad \sf \dashrightarrow \: x = \dfrac{6}{3} \times 373 [/tex]
[tex]\qquad \sf \dashrightarrow \: x = 2 \times 373[/tex]
[tex]\qquad \sf \dashrightarrow \: x =74 6 \: K[/tex]
Now, convert it to Celsius ~
i.e 746 - 273 = 473° C
So, the final temperature of the gas will be equal to 473° C
You find 6.21 g of diamonds. You measure that the diamonds have a volume of 1.77 ml. What is the
density of diamonds, and where would the diamonds fit into your density column?
Answer:
3.51 g/mL
Explanation:
Density can be found using the equation: density = mass / volume.
In this case, mass is given in grams (g) and volume is given in milliliters (mL).
You can find the density of the diamonds by plugging the given values into the formula and simplifying.
Density = mass (g) / volume (mL)
Density = 6.21 g / 1.77 mL
Density = 3.51 g/mL

A ball is hit so that it accelerates at 10 m/s2. The ball hits a glove with a force of 5 N. What is the mass of the ball?
Answer:
0.5 kg
Explanation:
» Concepts
Newton's second law, the Law of Acceleration, states that F = ma, where F = Force in Newtons, m = mass in kg, and a = acceleration in m/s^2.
» Application
We are asked to find the mass of the ball using the equation F = ma. We're also given the force and acceleration, so the equation looks like 5 = 10(m).
» Solution
Step 1: Divide both sides by 10.
[tex]5/10=10m/10[/tex] [tex]m=0.5[/tex]Thus, the mass of the ball is 0.5 kg.

What are two ways an engineer can build a car in order for it to accelerate faster
Explanation:
Take F=ma
a = F/m
For a higher, F higher or m lower
Means higher horse power for engine or lower mass for the car
An engineer can make a car to accelerate faster by having higher horsepower for the engine or less mass for the car.
What is an Acceleration?Acceleration is defined as the rate of change of velocity of an object with respect to time. These are vector quantities because they have both direction and magnitude. The orientation of an object's acceleration is given by the orientation of the net force acting on that object.
Acceleration in a car has everything to do with the torque and horsepower on the car where these two characteristics essentially determine the speed of the vehicle. The higher the torque and horsepower, the faster we go
Acceleration is expressed in terms of Force which is equals to
F=ma (m=mass, a= accelaration)
So, a = F/m
For a higher, F will be higher or m will be lower
Thus, an engineer can make a car to accelerate faster by having higher horsepower for the engine or less mass for the car.
