1 BTU mean 1 degree of F increased for 1 pound mass. Since the mass unit is in kg that means you need to convert it into pound. One metric ton means 1000kg and 1 kg mean 2.20462lb, then the water mass is: 1000kg x 2.20462lb/kg= 2204.62lb.
You are putting 110,000 btus of heat, so the calculation would be
Temperature increase= energy/mass = 110000btus/ 2204.62lb= 49.9 degree
<span>light colored and smooth surface would most likely be the best reflector of electromagnetic energy.Light, shiny surfaces are the best reflectors of radiation and they will allow the waves to reflect and bounce off rather than absorb. we can consider mirror as the example ,it will only reflect the light energy falling on them and it will not absorb. The darker coloured and rough surfaced substances will definitely absorb some amount of light falling on it. so light coloured smooth or shiny surfaced material would be the best reflector for electromagnetic energy.</span>
Answer:
serial in which container is filled
Solid -base of container
Liquid- above solid
Gas- above liquid
Explanation:
If any mixture of matter in different state (that solid , liquid or gas )are kept in any container, then substance with higher density will be settled at lowest surface first and similarly the substance with lowest density will be at upper part of container.
In the given container we have to keep solid, liquid and gas
- sold has the highest density,
- gas the lowest density and
- liquid has the density higher than gas but less than solid.
based on this
solid will be at surface of container
above sold will be liquid
above liquid will be presence of Gas
serial in which container is filled
Solid -base of container
Liquid- above solid
Gas- above liquid
Answer:
A and B are both requirements for a solar panel to generate usable current at home.
Explanation:
Solar panel operates through a group of cells, where each one of them captures/convert electrons making them move from one polarised region to another. The excited electrons can move from a region in excess of electrons (p region) to a region with a lack of electrons (n region).
This physical effect of electron moving from one side to another creates what we know as current flow.
This current flow from a solar panel does not vary with time in a determined frequency, so it's constant. This is the definition of a DC current. Since the household devices work with AC (variable sinusoidal current Alternate Current) a converter DC to AC is required.
Due to the fact that the solar panels only operate in the day when they recibe direct sunlight, there is the need to have batteries to store the energy for the night and the times where the sunlight is not enough to provide enough electron flow.
