Explanation:
In liquids, force of attraction between the molecules is less as compared to solids but force of attraction between the molecules is more strong as compared to gases.
Also, liquids do not have any definite shape and they acquire the shape or container or vessel in which they are placed.
Therefore, when a liquid is simply transferred from one container to another container then its volume remains the same.
When attempting to increase the distance traveled by a projectile, what must occur
Energy or power has to be increased to increase the distance travelled by the projectile.
Explanation:
Projectile motion is defined as when an object is thrown or projected at a particular angle and it reaches the ground after sometime due to acceleration and gravity.
For example, throwing a ball in air. To increase the distance travelled by the object due to projectile motion, one must increase the power at which the object to set.
To increase the distance of a projectile you must increase the power behind the projectile. However you must also change the angle if you are aiming for a specific point. By increasing the power the momentum transfers to the object and the projectile gains more velocity and more distance. Also remember that energy transfers. For more distance you must have more velocity.
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.

Answer:
Newton's second Law states that an object's acceleration is directly related to the net force applied and inversely related to the mass of the object.
Explanation:
Newton's second law states that when force is applied on an object, then it causes acceleration which is directly dependent on the net force applied and varies inversely with the mass of the object.
This law gives us the following equation:
where represents net force applied, represents mass of the object and represents acceleration caused.
The above equation can be rearranged to:
This equation shows that acceleration is directly dependent on net force and inversely dependent on mass of the body.
