Should nuclear energy be part of sustainable energy future? explain your answer

Physics
1 answer:
liraira [26]3 years ago
4 0

Answer:

Nuclear power is presently a sustainable energy source, but could become completely renewable if the source of uranium changed from mined ore to seawater. Since U extracted is continuously replenished through geologic processes, nuclear would become as endless as solar.

What is most likely the relationship between Mendel’s rules of genetics and Darwin’s idea of biological evolution?
xenn [34]

Answer:

Darwin's theory of natural selection lacked an adequate account of ... Darwinian principles now play a greater role in biology than ever before, .... Sadly, even if Mendel had lived to see the rediscovery of his work, he probably .... evolutionary forces are acting, a genetic equivalent to Galileo's law of inertia.

I need help with question two
zaharov [31]
I can't see numbers here, so here are all the answers:
1) the frequency is c/λ = 3e8/556e-9 = 5.39e14Hz
2) light travels at <span>299,792,458 m/s.  So in nanoseconds it's 0.299792458m.  This is about 1/3 of a meter which is about one foot.
3) length is L = ct = (</span>299,792,458 m/s)(6e-15) = 1.799e-6m or 1.799μm

1) Roland has built a circuit, and is using a device called an ammeter to measure how quickly electrical current is flowing thro
zaharov [31]

Answer:

1)  3.9 %

2) 1,38 kg

3) 0.13 cubic meters

Explanation:

Part 1)

Calculated current = 0.180 amps

Measured current: 0.173 amps

percent error :   \frac{0.180 - 0.173}{0.180} \,100=3.9 %

Part 2)

mass1 = 1,155 kg

mass2 = 0.22  kg

Addition; 1.155 + 0.22 = 1 375 kg  which should be rounded to just two decimals according to the addition rules for uncertainties:

Answer : 1,38 kg

Part 3)

Volume = 0.885 x 0.20 x 0.75 cubic meters = 0.13275 cubic meters

Notice that the smallest number of significant figures among the set of dimension given is two. Therefore, our answer should be rounded to two significant figures. That is:

Volume = 0.13 cubic meters
