Answer: time; mass

Explanation:

The equation E=mc^2 shows that energy, e, and mass, m, are linked.

For objects moving in a straight line, the special theory of relativity applies to show that space and time are linked.

Why can light travel through outer space, but sound cannot?

WINSTONCH [101]

Usually, sound needs a medium to travel through, like a vacuum for example.

Light does not need a medium to travel, and since air is considered a medium, light is not dependent on that.

On the other hand, sound needs a medium to travel through, and outer space doesn't contain space, therefore, no sound.

What is the heat needed to raise the temperature of 24.7 kg silver from 14.0 degrees celsius to 30.0 degrees celsius? specific h

Citrus2011 [14]

The amount of heat needed to increase the temperature of a substance by $\Delta T$ is given by
$Q=m C_s \Delta T$
where
m is the mass of the substance
$C_s$ is its specific heat capacity
$\Delta T$ is the increase of temperature

The sample of silver of our problem has a mass of $m=24.7 kg$ . Its specific heat capacity is $C_s = 236 J/g^{\circ}C$ and the increase in temperature is
$\Delta T=30.0^{\circ}-14.0^{\circ}C=16.0^{\circ}C$

Therefore, the amount of heat needed is
$Q=mC_s \Delta T=(24.7 kg)(236 J/g^{\circ}C)(16.0^{\circ}C)=9.32 \cdot 10^4 J$
