Answer:
Work occurs when a force acts on an object and causes a displacement of that object.
Explanation:
a . Force applying over a distance or in other words force causing the movement (displacement) of an object is known as Work.
b. An activity with mental or physical effort is done in order to achieve a result is called work.
c. A constant force integrates the product of the force and distance.
Ex : 1) when the body moves in the direction of force
2) shooting a bullet
3) Pushing a car horizontally from rest
4)walking up stairs
5) sawing a log.
Answer:
m = 50 [kg]
Explanation:
The potential energy can be calculated by means of the following equation.
where:
Ep = potential energy = 735 [J]
m = mass [kg]
g = gravity acceleration = 9.81 [m/s²]
h = elevation = 1.5 [m]
Now replacing:
Answer:
d
Explanation:
The minimum energy configuration in electrostatics states that Charges always reside on the surface of a conductor. If anyhow they were inside, an electric field would exist inside and would act to move them to the surface,
Therefore, the drawing that shows where the charges reside when they are in equilibrium is a hollowed-out "hole" in the interior of the circle, with positive signs surrounding the exterior edge. This means that the d part is the correct answer.
For the speed of an object you need to know how far it is travelling in a given time. Typically you do this by measuring the time it takes for the object to travel a set distance.
<span>For the velocity of an object you also need to know the direction the object is travelling in.
