Answer:
14.44 revolutions
Explanation:
unit conversion:
85mile/hour = 85mile/hour * 5280ft/mile * 1/3600hours/second = 448800ft/hour = 124.67 ft/s
1800rev/min = 1800rev/min * 1/60min/seconds = 30 rev/s
The time it takes for the 85mph base ball to travel 60 ft is
t = s/v = 60 / 124.67 = 0.4813 seconds
By that time, the number of revolution it would make is:
r = 30 * 0.4813 = 14.44 revolutions
The same amount of work being done over a longer period of time we must have power.
A battery is a device that stores chemical energy and converts it to electrical energy. Two terminals made of different chemicals (typically metals), the anode and the cathode; and the electrolyte, which separates these terminals.

Answer:
50m; 0m/s.
Explanation:
Given the following data;
Initial velocity = 20m/s
Acceleration, a = - 4m/s²
Time, t = 5secs
To find the displacement, we would use the second equation of motion;
Substituting into the equation, we have;
Displacement, S = 50m
Next, to find the final velocity, we would use the third equation of motion;
Where;
- V represents the final velocity measured in meter per seconds.
- U represents the initial velocity measured in meter per seconds.
- a represents acceleration measured in meters per seconds square.
<em>Substituting into the equation, we have;</em>
Final velocity, V = 0m/s
<em>Therefore, the displacement of the bus is 50m and its final velocity is 0m/s.</em>
The correct answer is; Yes, you can be unconsciously eavesdropping.
Further Explanation:
When this occurs it is called the “The Cocktail Party Phenomenon.” Your mind can focus on one conversation that is being made and drown out all other speech and things going on around you. This makes your brain have auditory attention on one specific conversation.
The sensory hearing in the person listening to the conversation is subconsciously filtering the conversation into its own stream in the brain. This phenomenon can also detect certain words that are important to the person with a large amount of noise in the background.
This occurs in the left hemisphere of the brain in the superior temporal gyrus region.
