The correct answer is high temperature. Fusion occurs on the sun where the temperature is high and it can happen. There is no way to have the necessary amount of high energy on earth that can enable fusion and usable energy to occur because of the way things on earth work.
Wavelength is the amount of time during an event, and frequency is the number of times something occures. They are related through the theory of time.
Answer:
I = 2.375 × 10-³ Kgm²
Explanation:
Using the formulas to calculate the moment of inertia of a solid cylinder:
I = ½MR²
Where;
I = moment (kgm²)
M = mass of object (Kg)
R = radius of object (m)
Total moment of inertia of the two disks is expressed as: I = I(1) + I(2)
That is;
I = ½M1R1 + ½M2R2
According to the provided information;
R1 = 2.50cm = 0.025m
M1 = 0.800kg
R2 = 5.00cm = 0.05m
M2 = 1.70kg
I = (½ × 0.800 × 0.025²) + (½ × 0.05² × 1.70)
I = (½ × 0.0005) + (½ × 0.00425)
I = (0.00025) + (0.002125)
I = 0.002375
I = 2.375 × 10-³ Kgm²
Answer:
D
Explanation:
The tectonic plates move on the mantle, sort of floating on it as they are part of the crust. When they collide things like mountain ranges form, and big earthquakes happen.
<span>2. For each pair of substances, identify the substance that will take more energy to heat from 20C to 100C and explain why. Specific heat for water- 4180 J/kg°C. Specific Heat for silver- 235 J/kg°C. Specific heat for iron-450 J/kg°C.
a. 30 g of water vs. 300 g of water
Q = mcp</span>ΔT
Q(water) = (0.03kg)(4180 J/kg°C)(100-20)
<span>Q(water) = 10,032 J
</span>Q(water) = (0.3kg)(4180 J/kg°C)(100-20)
Q(water) = 100,320 J
<span>300g of water takes mroe heat than 30g of water.
b. 500 g of iron vs. 500 g of silver
</span>Q = mcpΔT
Q(iron) = (0.5g)(-450 J/kg°C)(100-20)
Q(iron) = -18,000J
Q(silver) = (.5g)(-235 J/kg°C)(100-20)
Q(silver) = -9,400J
Iron gives off more heat than silver
