Let's assume that the coordinate system is defined as positive in the first quadrant.
The system has its origin in the place where Ingrid kicks the football ball.
We have then that the horizontal component is given by:
Rewriting we have:
Rounding the obtained result we have:
Answer:
The horizontal component of the initial velocity to the nearest tenth is:
Answer: Efficiency signifies a peak level of performance that uses the least amount of inputs to achieve the highest amount of output.
Explanation: It minimizes the waste of resources such as physical materials, energy, and time while accomplishing the desired output.
Melatonin is a hormone that regulates the circadian rhythms in the body like thee sleep wake cycle. Melatonin when taken as a supplement is absorbed directly by the body so it affects the body immediately since it goes to the bloodstream directly after it is dissolved in the body.
Answer: No, the student does not do any work on the wall.
Explanation: The work is defined as the movement of an object done/caused by a force.
And it can be calculated as:
W = F*d
where W is work, F is force and d is the displacement of the object
In this case, the student is applying force on the wall, so we have the first part, but we also know that the wall does not move, so in this case, d = 0, which would imply that the work applied to the wall must be equal to zero
(because W = F*0 = 0)
So the answer is no, the student does not do any work on the wall.
Answer:
you will get charge
Explanation:
Most shocks happen because you and the car have picked up opposite charges. Leaving your seat separates these charges, creating the potential for a static shock. Touching the metal of the car as you get out lets the charge balance out by flowing harmlessly through your hand
