Yes. There were a few theories that lacked enough evidence at the time of their creation like that the sun was the actual center of the universe instead of the earth itself. The theorist behind this idea lacked some key evidence to this theory and wasn't able to find it before his death. A few decades later another scientist looked into this theory and ended up finding the missing evidence and was able to prove it and that is why we accept it as fact today.

Yes, it is possible for several scientists who have never met each other to contribute to the same scientific knowledge, theory, or law. Scientific knowledge is a continuous process. Most scientists who work in the same field never met each other. However by their work they contribute to the same scientific knowledge.

1. If we increase the distance to twice it's original value, the light intensity is reduced by one-fourth, the light intensity would be:
I0/4

2. rms magnetic field is inversely proportional to distance, so the new rms magnetic field would be:
B0/2

3. average energy density is inversely proportional to the square of the distance, so the new average energy density is:
E0/4

Where does all of this energy come from
Amiraneli [1.4K]

Answer: All of our energy comes from the sun, which is our nearest star. The sun sends out huge amounts of energy through its rays every day. We call this energy solar energy or radiant energy. Without the sun, life on earth would not exist, since our planet would be totally frozen.

if pete (mass =90.00kg) weighs himself and finds that he weighs 30.0 pounds, how far away from the earth is he?
Svet_ta [14]

Here we know that mass of the person is 90 kg

His weight is given as 30 lbf

so here we can convert it into Newton as we know that

1 lbf = 4.45 N

Now from above conversion

30 lbf = 30 \times 4.45 = 133.45 N

now we can use this to find the gravity at this height

mg = 133.45

90\times g = 133.45

g = 1.49 m/s^2

now we know that with height gravity varies as

g' = g(\frac{R}{R+H})^2

1.49 = 9.8(\frac{6.37\times 10^6}{6.37\times 10^6 + h})^2

h = 1.0 \times 10^7 m

so above is the height from the surface of earth
