For a pendulum with a massless rope 'L' meters long, swinging through
a small arc, the period of the swing is
2 π √(L/g) seconds .
and it doesn't depend on the mass of the thing on the end of the rope ...
that could be a pebble or a bus.
For the girl on the 2.5-m rope,
Period = (2 π) √(2.5 / 9.8) = 3.17 seconds
Frequency = 1 / period = about <em> 0.315 Hz .</em>
if A is closer to the x-axis then its "faster"
P-waves pass through both mantle and core, but are slowed and refracted at the mantle / core boundary at a depth of 2900 km. S-waves passing from the mantle to the core are absorbed because shear waves cannot be transmitted through liquids. ... The core has a radius of 3470 km.
Answer: 1231.2 km/h
Explanation: 342 x 3.6 ( because 1 m/s equal 3.6 km/h)
Answer:
False
Explanation:
It will be more than one.
