Answer:
The ball will fall back and land to Elle's hands.
Explanation:
The bus move in a straight line with constant velocity means that there is no change of direction and no acceleration. Inertia can change the direction of the ball and acceleration can change its velocity. Since these two factors is not present in this scenario, the ball only has vertical movement. Thus the ball will land where it was thrown, in Elle's hands.
Correct Answer:
The ball will fall back to Elle's

Boyle’s Law states that, when temperature is held constant, the pressure and volume of a gas are inversely proportional.
What is meant by gas laws ?
Gas laws are defined as the laws that govern the properties of gases by determining the relationships between the pressure, volume and temperature of the gases.
Here,
Boyle's law is the gas law that governs the relationship between the pressure and volume of gases.
Boyle's law states that, for an ideal gas at a unit mass, the pressure of the gas is inversely proportional to the volume of the gas, at constant temperature.
P 1/V
PV = a constant
When the temperature of the gas is held constant.
Hence,
Boyle’s Law states that, when temperature is held constant, the pressure and volume of a gas are inversely proportional.

Jose wandered for 2 hour with speed at 2 kilometers per hour.
What is speed?
The speed of an item, which is a scalar quantity in everyday usage and kinematics, is the size of the change in that object's position over time or the size of the change in that object's position per unit of time.
The instantaneous speed is the upper limit of the average speed as the duration of the time interval approaches zero. The average speed of an item in a period of time is equal to the distance travelled by the object divided by the duration of the period.
Given parameters:
Distancetravelled by Jose = 4 kilometer.
Speed of Jose = 2 kilometers per hour.
Now from definition of speed:
Total time taken = Distance travelled by Jose ÷ Speed of Jose
= 4 kilometer ÷ 2 kilometers per hour.
= 2 hour.
Hence, Jose wandered for 2 hour.
