Explanation:

An object whose particles are held by strong intermolecular forces of attraction is known as a solid substance.

In solids, particles have least kinetic energy and they can only vibrate at their position.

Therefore, solids have a definite shape and volume.

Hence, when we place a solid object in a container then it is unable to take the shape of container because its molecules are held strongly with each other.

Thus, they bond between its molecules cannot be broken down easily.

Answer: 7.436 s

Explanation:

This situation is related to vertical motion, specifically free fall and can be modelled by the following equation:

$y=y_{o}+V_{o} t+\frac{gt^{2}}{2}$

Where:

$y= 0m$ is the final height of the object (when it makes splash)

$y_{o}=271 m$ is the initial height of the object

$V_{o}=0 m/s$ is the initial velocity of the object (it was dropped)

$g=-9.8m/s^{2}$ is the acceleration due gravity (directed downwards)

$t$ is the time since the objecct is dropped until it makes splash

$0=y_{o}+0+\frac{gt^{2}}{2}$

Clearing $t$ :

$t=\sqrt{\frac{-2y_{o}}{g}}$

$t=\sqrt{\frac{-2(271 m)}{-9.8m/s^{2}}}$

Finally:

$t=7.436 s$

How do you know the speed of an electromagnetic wave in a vacuum?

ycow [4]

Electromagnetic waves need no matter to travel - they can travel through empty space (a vacuum). In a vacuum, all electromagnetic waves travel at approximately 3 x 108 m/s - which is the fastest speed possible. ...
Light traveling value through an optical Fibre is, 2 x 108 m/s. Hope that helps.
