Answer:
Object 1.
Explanation:
Given that,
Force applied = 100 N
The spring constant of object 1 = 100 N/m
The spring constant of object 2 = 200 N/m
Using Hooke's law, we find the force applied on the object to stretch.
For object 1,
F₁ = k₁x₁
For object 2,
F₂ = k₂x₂
Object 1 stretches 1 m and object 2 stretches 0.5 m. Hence, object 1 stretches furthur.
Answer:
Distance = 40 meters.
Explanation:
Given the following data;
Force = 25N
Time = 10 seconds
Power = 100 Watt
To find the distance;
First of all, we would determine the work done;
Workdone = power * time
Workdone = 100 * 10
Workdone = 1000 Nm
Next, we use the following formula to find the distance;
Workdone = force * distance
1000 = 25 * distance
Distance = 1000/25
Distance = 40 meters.
Answer:
Elastic potential energy
Elastic potential energy is stored in the spring. Provided inelastic deformation has not happened, the work done is equal to the elastic potential energy stored.
Explanation:
becuse
The electrical potential energy of a particle in a uniform electric field depends on 1) the charge of the particle 2) the distance from the source of the field 3) the magnitude of the electric field
In fact, the electrical potential energy is defined as
(1)
where q is the charge and V is the voltage. Since the electric field is uniform, the voltage increase linearly with the distance from the source:
(2)
where E is the electric field strength and d is the distance. Putting (2) into (1), we find
therefore, we see that the potential energy of the particle depends on the charge q, the distance d from the source and the electric field strength E (which is constant at every location, because the field is uniform)
You can consider the asteroid belt to mark the boundary. From there, 'inner' and 'outer' refer to their distances from the sun.
