Answer with Explanation:
The "Boyle's Law" is also referred to as the "Mariotte's Law." This law shows the inverse relationship between the pressure of a gas and the volume of a container. This means that if the pressure is increased, the volume will decrease and vice-versa.
In the situation above, the plastic water bottle serves as the container. The little boy blew air into it, making the volume of the container increase. It carried the plastic ball with it, that's why it got stuck.
In order to remove the ball, the older brother will have to apply Boyle's law by compressing the plastic water bottle. His compression will increase the pressure in the container. This will allow the compressed air to rush out, thus moving the stuck ball with it. This will result into decreased volume in the container as well.
This is true, provided that both mass and temperature remain constant.
Answer:
by pushing down on the bottle to increase the air pressure inside the bottle
Explanation:
The pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature.
ball drops 45m under g=10m/s/s
45=1/2x10xt^2 ... application of kinematic equaion from rest
90/10=t^2
t=3
24.0 m in 3 secs => 8m/s no air resistance
The ball's initial speed is calculated using the principles of projectile motion. First, the time it takes for the ball to hit the ground is found using the vertical distance and acceleration due to gravity. the initial speed to be approximately 7.9 m/s.
The problem describes a case of projectile motion, a common topic in physics. Since the ball is thrown horizontally, the initial vertical velocity of the ball is zero. We're given that the horizontal distance covered is 24.0 m and the vertical distance is 45.0 m.
Because the horizontal and vertical motions are independent, we can use the equations of motion to solve the problem. First, we have to find the time it takes for the ball to hit the ground. Using the equation of motion
"y = 0.5*g*t²",
where y = 45 m is the vertical distance, g = 9.8 m/s² is the acceleration due to gravity, and t is the time in seconds. Solving for t gives us the square root of (2*y/g), which is approximately 3.03 seconds.
Second, we use this time to find the initial speed of the ball. The horizontal distance covered x = 24.0 m is equal to the product of the time it's been travelling and its initial horizontal speed (v = x/t). Using the time from the previous step, we can find the initial speed to be approximately 7.9 m/s.
