Answer: The spring potential energy must equal or exceed the energy to raise the mass to loop height and the minimum kinetic energy needed to keep the mass in contact with the top of the loop
kd² = 5Mrg
h = kd²/2Mg
Explanation:
at top of loop
Mv²/r = Mg
v² = rg
½kd² = ½Mv² + Mgh'
½kd² = ½M(rg) + Mg(2r)
½kd² = 2.5Mrg
kd² = 5Mrg
½kd² = Mgh
h = kd²/2Mg
Answer: I dont understand
Explanation:
Answer:
Explanation:
given,
radius of the sphere, R = 54.5 cm
R = 0.545 m
Electric magnitude of the conductor,E = 4 x 10⁵ V/m
Electric potential just outside of the surface,V = ?
we know,
Hence, the Potential just outside the surface is equal to
An example of conductors of heat would be iron pans. a example of electric insulators would be copper, gold and silver. to contrast conductors and insulators, insulators let electricity pass through them while conductors restricts electricity. both conductors and insulators can work with lithium and sodium.
