B. 3V as they both have the same resistance and the potential difference across the circuit could be divided by 2
First figure out the time by using the equation (you know v and x):
Then, use the following equation to figure out what y (height of the field house is):
Remember that you can always analyze half of the scenario by dividing the time in half, and setting vy = 0 if at all it helps.
If a material is going to be used for electrical wiring, it must have high conductivity. Electrical conductivity is the measure of a materials ability to allow the movement of an electric charge. Its SI is the Siemens per meter. Electrical conductivity is also known as specific conductance, a material with higher electrical conductivity would be the best preference for making electric wires.
A speed graph shows us how the speed of a moving object changes with time. The steeper the graph, the greater the acceleration. A horizontal line means the object is moving at a constant speed
Answer:
For steam, heat released E = 15.26KJ
For water, heat released E2 = 6.91KJ
Explanation:
Given;
Mass(steam) ms = 25g
Mass (water) mw = 25g
Change in temperature of both steam and water ∆T = 100-34= 66°C
Specific heat of water C = 4.186 J/g.°C
Specific Latent heat L = 334J/g
For steam;
Heat released E = msL + msC∆T
E = (25×334) + (25×4.186×66)
E = 15256.9J
E = 15.26KJ
For water;
Heat released E2 = mwC∆T
E2 = 25×4.186×66
E2 = 6906.9J
E2 = 6.91KJ
