Assuming the pendulum is on the earth and g = 10m/s2, what is the period if the length is 10 m?
a. 2π s
b. 1 s
c. π s
d. π/2 s

A. 2π s

Explanation:

Period of a pendulum is:

T = 2π √(L/g)

Given L = 10 m and g = 10 m/s²:

T = 2π √(10 m / (10 m/s²))

T = 2π s

A. 2π s

Explanation:

Assuming the pendulum is on the Earth and g = 10m/s2, the period is 2π s, if the length is 10 m.

T = 2π √(L/g)

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
