Answer:
Eelas = 5 [J]
Explanation:
Elastic energy is associated with the ability that has a spring or any other material with elastic properties.
We can calculate the elastic energy by means of the following equation:
where:
k = constant spring = 2.5 [N/m]
x = distance stretched = 2 [m]
Answer:
(a) upper : 3.18 m, lower: 2.58
(b) upper : 3180 mm, lower: 2580 mm
(c) upper : 2.81 m³, lower: 1.5 m³
Explanation:
given information:
the distance ranged from 43 to 53 cm
length of cylindrical pillar = 6 cubits
diameter = 1 cubit
(a) the cylinder's length in meters
upper = 53 cm x 6 cubits
= 318 cm
= 3.18 m
lower = 43 cm x 6 cubits
= 258 cm
= 2.58 m
(b) the cylinder's length in millimeters
upper = 3.18 m
= 3180 mm
lower = 2.58 m
= 2580 mm
(c) the cylinder's volume in cubic meters
upper : V = πr²l
= π (0.53m)² (3.18)
= 2.81 m³
lower : V = πr²l
= π (0.43m)² (2.58)
= 1.5 m³
The charge would be in equilibrium so there would be no charge in the body of the conductor.
Answer:
(b) there cannot be any charge in the body of the conductor
15km = 15,000m
1/2h = 1800s
15,000 / 1,800 = 25/3ms^-1
Answer:
Explanation:
From Hooke's law,
Substistuting the values, you can ignore the minus sign, since it is there to state that the force is always in the opposite direction of the deformation, and has no influence otherwise, and your constant is
