It's called covelant bonding
Answer:
Heat energy needed = 1243.45 kJ
Explanation:
We have
heat of fusion of water = 334 J/g
heat of vaporization of water = 2257 J/g
specific heat of ice = 2.09 J/g·°C
specific heat of water = 4.18 J/g·°C
specific heat of steam = 2.09 J/g·°C
Here wee need to convert 0.500 kg water from 50°C to vapor at 110°C
First the water changes to 100°C from 50°C , then it changes to steam and then its temperature increases from 100°C to 110°C.
Mass of water = 500 g
Heat energy required to change water temperature from 50°C to 100°C
Heat energy required to change water from 100°C to steam at 100°C
Heat energy required to change steam temperature from 100°C to 110°C
Total heat energy required
Heat energy needed = 1243.45 kJ
Answer:
The charge flows in coulombs is
Explanation:
The current magnitude of current is given by the resistance and the induced Emf as:
, , , Ω
,
Replacing :
7.4 s
Explanation:
Given:
To solve the time it takes for the object to come to a stop, we are going to use the equation below:
Using the given values above, we get
Solar flares are bright, high-energy rays from the sun. Once it is intense enough, it can affect the Earth with penetrating radiation. Having this knowledge, probes that study or document for these solar flares near the sun's atmosphere should be able to resist high temperatures and high radiation using certain insulators and light materials suitable for space monitoring.
