The temperature of a 2.0 kg block increases by 5 0c when 2,000 j of thermal energy are added to the block. What is the block's s

pecific heat?
Physics

FinnZ [79.3K]3 years ago
7 0

Mass of the block = 2 kg

Temperature is increased by ΔT = 50 °C

Energy consumed by the block in raising the temperature = 2000 Joules

Let the specific heat capacity of the block be "c".

Formula to be used:

Heat gained = m × c × ΔT

Plugging the values:

2000 = 2 × c × 50

c = \frac{2000}{2\times 50}

c = 20 J/ kg °C

Hence, the specific heat capacity of the block is: 20 J/ kg °C

What does special relativity reveal about the speed of light relative to its source?
Vladimir [108]

Regardless of the source's mobility, light travels at the same speed.

<h3>What makes special relativity so crucial?</h3>

In the calculating and interpretation of high-velocity phenomena, as well as on our methods of thinking, Einstein's special relativity has had a significant influence on the area of physics. Today, we have a considerably better knowledge of space and time than we did at the start of the century.

<h3>Why is special relativity thus named?</h3>

Because it exclusively uses inertial frames to apply the concept of relativity, the theory is known as "special". General relativity, which Einstein created, applies the principle broadly, that is, to any frame, and this theory takes the gravitational forces into account.

What happens if an air conditioner is used in a house that is not well insulated and not well scaled? Explain in terms of energy
stira [4]
It will use a lot more energy (electricity) to cool down the room. Because heat energy from outside the room can easily transfer into the room again if the room is not well insulated. So more energy is needed to cool down the room again

A radio station broadcast on a frequency of 3.7 mhz what is the energy of the radio wave
Ratling [72]

A radio station broadcast on a frequency of 3.7 mhz what is the energy of the radio wave A radio station broadcasts its programmes at a wavelength of 500 m. Find the frequency of the radiowaves transmitted by the radio station, if the speed of radiowaves in air is 3 x 108 m/s. Ans: 6 x 10 Hz

<h3>What is radio station ?</h3>

Radio broadcasting is the act of sending audio (sound), occasionally together with accompanying metadata, across radio waves to radio receivers used by the general public. Unlike satellite radio, which uses a satellite in Earth's orbit, terrestrial radio broadcasting uses a land-based radio station to transmit radio waves. The listener needs a broadcast radio receiver to hear the material (radio). A radio network with which stations frequently have affiliations provide content in a standard radio format, whether through broadcast syndication, simulcasting, or both. Radio stations use a variety of modulations to transmit their signals, including FM (frequency modulation), which is an older analog audio standard, and AM (amplitude modulation).
