Answer:
you need kinetic energy because it is the energy that is used when In motion
Answer:
-1
Explanation:
The coefficient of y in the equation x+y=40 is 1. To make the y-terms cancel when the second equation is added, its coefficient must be -1. It has a coefficient of 1 now, so that equation should be multiplied by -1.
(x +y) +(-1)(y) = (40) +(-1)(0)
x = 40 . . . . . . . simplified; y-terms were cancelled
We have the weight acting downwards (W=mg) from the bob.
When the pendulum swings, there is air resistance acting on the bob.
The time taken to complete one oscillation.
The length of the string affects the time taken.
The tension of the string.
Answer:
Force is a vector quantity which when applied to an object can cause change in its velocity. When Force is applied to an object, the object if stationary moves to a certain distance depending upon the amount of force applied.
A pulley is a wheel with a groove that holds a rope, cable or belt, and is used to help lift an object.
The relationship of Force and Distance is the same for a fixed pulley as well. Except for one thing:
Normally the distance covered by an object is in the direction of the Force.
Using a pulley, an object can be moved with that same Force in a different direction. Using a pulley, a person can apply force in a direction suitable for him while moving the object.
<em> Force = mass of an object * Distance Covered</em>
Answer:
Technician b is correct.
Explanation:
Crimping cable allows a firm connection in mechanical terms and allows a low resistance path for the signal or the current flow, solder although it is better in terms of electrical conduction, can be impractical if the cable is subjected to excessive movement.
A crimped cable with excessive movement can also be easily broken at the ends, where it joins the part of the cable that is crimped, for this reason, a cable that is in excessive motion is recomended to be spliced by joining cable with cable
.
In order to decide which metod is better for splicing cables its necessary to evaluate each situation separatly.
