Hello!
A stretched spring has 5184 J of elastic potential energy and a spring constant of 16,200 N/m. What is the displacement of the spring ?
Data:
For a spring (or an elastic), the elastic potential energy is calculated by the following expression:
Where k represents the elastic constant of the spring (or elastic) and x the deformation or displacement suffered by the spring.
Solving:
Answer:
The displacement of the spring = 0.8 m

Chlorine gas or just chlorine?
Answer:
The telescope can gather light 1600 times more than the human eyes can!
Explanation:
The light gathering ability of an optical element is directly proportional to its area of opening.
So, in comparing the light gathering abilities for two objects, it is just the ratio of their area of opening.
Let the diameter of the telescope be D = 1 m
And the diameter of the human eyes be d = 2.5 cm = 0.025 m
Light gathering ability of the telescope compared to the eyes = D² ÷ d²
= (D²/d²) = (1²/0.025²) = 1600 times.
The telescope can gather light 1600 times more than the human eyes can!
Hope this Helps!!!
Satellites are objects which orbit the planet. The natural satellite of Earth, in this case, is moon
Answer:
34.75m
Explanation:
Parameters given:
Net force, F = 320N
Work done by net force, W = 4700 N
Angle, θ = 65º
Work done at an angle is given as:
W = F * d * cosθ
Where d = distance travelled
θ is the angle between the force and the direction of motion.
Therefore,
4700 = 320 * d * cos65
=> d = 4700/(320 * cos65)
d = 34.75 m
