insens350 [35]

Answer:

Liquid

Explanation:

Solids do not change shape, so we know it's not a solid.

Gases take the shape of their container, but they also expand to the volume of the container.  The substance in this problem has the same volume in different size containers, so we know it's not a gas.

The substance must be a liquid.  It takes the shape of its container but has a constant volume.

Mashcka [7]

Explanation:

P.E=MGH

(1) P.E=5×10(G)×3

= 150 kg m^/s^ ( ^ =sqaure)

(2) P.E=5×10×6

= 300 kg m^/s^

Hope it helps, just remember the formula u can solve any question regarding gravition of earth (P.E=Mgh)

The length of a displaced pendulum body which passes its lowest point twice every second
Troyanec [42]

Answer:

0.248 m

Explanation:

The period of a simple pendulum is given by

T=2\pi \sqrt{\frac{L}{g}}

where

L is the length of the pendulum

g is the acceleration of gravity

The pendulum in the problem passes its lowest point twice every second: this means: this means that it makes one complete oscillation in one second, so its period is 1 second:

T = 1 s

And using

g=9.8 m/s^2

We can rearrange the equation above to find L, the length of the pendulum:

L=\frac{T^2 g}{4\pi^2}=\frac{1^2(9.8)}{4\pi^2}=0.248 m
