Answer:
R = 35.27 Ohms
Explanation:
Given the following data;
Voltage = 230V
Power = 1500W
To find the resistance, R;
Power = V²/R
Where:
V is the voltage measured in volts.
R is the resistance measured in ohms.
Substituting into the equation, we have;
1500 = 230²/R
Cross-multiplying, we have;
1500R = 52900
R = 52900/1500
R = 35.27 Ohms.
Therefore, the resistance which the heating element needs to have is 35.27 Ohms.
Answer:All three states of matter (solid, liquid and gas) expand when heated. ... Heat causes the molecules to move faster, (heat energy is converted to kinetic energy ) which means that the volume of a gas increases more than the volume of a solid or liquid.
Explanation:well I tried lol she just copied and pasted faster than I could
The sun radiates a lot of things we need like vitamin D and heat. It also is the energy source of organisms that survive off of photosynthesis, like plants, which we or other consumers eat.
It's like this:
Sun--->Producers (Plants and Protists) ---> Consumers (animals and humans) ---> Decomposers (mostly bugs, bacteria, and fungi)
Ac=centripetal accelration
Fc= centripetal force
V= tangential speed
