Besides the force due to gravity or g, what else determines the period of a pendulum?

The period of a pendulum is determined by the <em>length of the cord</em> and the acceleration of gravity where the pendulum is located.

Answer:

Option (C)

Explanation:

The time period of simple pendulum is defined as the time taken by the bob to complete one oscillation.

The formula to calculate the time period of a simple pendulum is given by

$T = 2\pi \sqrt{\frac{l}{g}}$

Time period depends on the acceleration due to gravity and the effective length of the pendulum.

The effective length is the sum of length of cord and the radius f bob.

The effective length of the pendulum is defined as the distance between the point of suspension and the centre of gravity of the bob.

the skate shop owner wants 30 percent of each order to include longboards. he wants to know how many longboards to order out of

allsm [11]

Answer:

Explanation:

The question is essentially asking 30% of 50.

to get 30 percent you first need to find out 10 percent.

10 percent is calculated by dividing 50 by 10, giving you 5.

you then need to get 30 percent from the 10 percent just calculated.

to do so, you need to times 10 percent by 3, therefore have to time 5 buy 3, leaving you with 15

A disk with a rotational inertia of 5.0 kg. m2 and a radius of 0.25 m rotates on a frictionless fixed axis perpendicu-

diamong [38]

Answer:1.6 rad/s

Explanation:

Given

moment of Inertia of disk $I=5 kg-m^2$

radius of disc $r=0.25 m$

Force $F=8 N$

Torque $T=I\alpha =F\cdot r$

$5\times \alpha =8\times 0.25$

$\alpha =0.4 rad/s^2$

using

$\theta =\omega _0\times t+\frac{\alpha t^2}{2}$

$\pi =0+\frac{0.4t^2}{2}$

$2\pi =0.4t^2$

$t^2=5\pi$

$t=\sqrt{5\pi }$

$t=3.96 s$

$\omega =\omega _0+\alpha t$

$\omega =0+0.4\times 3.96$

$\omega =1.58 rad/s\approx 1.6 rad/s$

How do distinctive rock strata support the theory of continental drift?

Scorpion4ik [409]

“It states that parts of the Earth's crust slowly drift atop a liquid core. The fossil record supports and gives credence to the theories of continental drift and plate tectonics. ... Continental Coastlines appearing to fit together,Fossil Distrubution, Distinctive Rock Strata, and Coal Distrubution.”
