you have two pendulums with cords that are exactly the same length. one is on earth (with an acceleration due to gravity of 9.81
olga55 [171]
From  T = 2π√(l/g).

Since the lengths are the same, so that is a constant.

T α 1/√g

So the period T is inversely proportional to the square root of gravity g.

So the one with a bigger gravity g would have a shorter period

and

the one with smaller gravity g would have a longer period.

Therefore the period on the Moon with gravity of 1.63 m/s² would be longer period than that on the Earth with gravity of 9.81 m/s²

A 1100 kg car is traveling around a flat 82.3 m radius curve. The coefficient of static friction between the car tires and the r
Novay_Z [31]

Answer:

The maximum speed of car will be 20.5m/sec

Explanation:

We have given mass of car = 1100 kg

Radius of curve = 82.3 m

Static friction \mu _s=0.521

We have to find the maximum speed of car

We know that at maximum speed centripetal force will be equal to frictional force m\frac{v^2}{r}=\mu _srg

v=\sqrt{\mu _srg}=\sqrt{0.521\times 82.3\times 9.8}=20.5m/sec

So the maximum speed of car will be 20.5m/sec
