Answer:
percentage by volume of the solute = 45%
Explanation:
The percentage by volume of the solute in a solution is the percentage of the volume of the solute as against the overall volume of the solution.
In this example,
volume of solution = 300mL
volume of solute = 135mL
% volume of solute = (volume of solute ÷ volume of solution) × 100
= (135 ÷ 300) × 100
= 0.45 × 100 = 45%
∴ percentage by volume of the solute = 45%
Since the orange rolls off the table and is (falling) its potential energy turnes into kinetic energy.

Here we have a projectile motion. It is type of motion that is made of a vertical shot and a horizontal shot. This is how we will solve it.
Firste step is to find horizontal and vertical component of a speed.

\\ v_{0y} = v_{0} * sin \alpha [/tex]
We are given this information:

Angle is negative because it is below the horizontal.
VERTICAL SHOT
Time needed for a grenade to fall to the bottom of a building is given by a formula:

We used negative value for a speed because it is considered that upwards shot has positive value and downwards shot has negative value.
The grenade will not explode before it hits the ground.
HORIZONTAL SHOT
<span>The horizontal distance from the building at which the grenade will land is called range. The formula for a range is given by:
</span>
The grenade will hit the ground at distance of 47.89m.
(1.00 atm) (0.1156 L) = (n) (0.08206 L atm / mol K) (273 K) I hoped that helped
Friction I believe is the answer
hope this helps
