A. Displacement
O B. Time
C. Acceleration
D. Average speed
To calculate velocity in Physics, the two necessary measurements are displacement and time. Velocity is the speed in a specified direction, determined by dividing displacement by time.
In the field of Physics, the two measurements needed to calculate the velocity of an object are displacement and time. Velocity refers to the speed in a given direction and is calculated by dividing displacement (which gives direction information and distance) by the time it takes to move that distance. For example, if an object traveled 100 meters to the north in 20 seconds, the velocity would be 5 meters per second towards the north.

Show work clearly and completely (including formulas, calculations, units, etc. as done in class.)
The problem states that the ball is thrown 20 meters downrange. Since the ball is thrown horizontally, we can assume that the initial vertical velocity is zero. The only force acting on the ball is gravity, which causes it to accelerate downwards at a rate of 9.8 m/s² 1.
To calculate the pitching speed, we need to find the time it takes for the ball to travel 20 meters horizontally. Unfortunately, this information is not provided in the problem statement. Therefore, we cannot calculate the pitching speed.
A. 30.6 m
B. 122.5 m
C. 12.3 m
D. 49.0 m
B. Water molecules move from their fixed position.
C. Water molecules lose energy.
D. The temperature of the ice increases as it melts.
The answer for this question is part B that is Water molecules move from their fixed position.
This is because when water is freeze it is in a solid condition that means the molecules are held together tightly and are are vibrating in their fixed positions.
As soon as the molecules gain energy they start to move around from their fixed positions and turn into a liquid.
In the process of doing so ice melts and becomes water.
