Answer: One of the units used to measure incident energy is calories per centimeter squared (cal/cm2).
Explanation: Incident energy this is defined as the amount of thermal energy impressed on a surface, at a certain distance from the source, generated during an electrical arc event.
The working distance is the distance from where the worker stands to the source location. The most common distance for which incident energy has been determined in tests is 18 inches.
Answer:
1.65 m
Explanation:
The motion of the ball is a projectile motion, so it is a parabolic motion with two independent motions:
- on the x-axis, a uniform motion with constant speed 
- on the y-axis, a uniformly accelerated motion with constant acceleration 
downward.
First of all, we need to find the time t at which the ball has travelled halfway to the chatcher, i.e. at a distance of 
. This can be found by using the relationship between distance, time and velocity along the horizontal direction:
So now we can move to the vertical motion, and we can calculate the distance covered vertically by the ball while falling for t=0.58 s, by using:
DIVIDE THEN MUTPLY THEN YOU AEMPLY SUCK
Answer:
Explanation:
he answer is 540 because you need to do the area of the wall times six. 15 times 6 times 6 equals 540
