Answer:

One of the most relevant discoveries is the Big Bang

Explanation:

The Big Bang can be defined as the moment when all matter resurfaces from nothing, that is, the origin of the Universe. According to this theory, matter was a very small point and it had a high density that exploded and expanded in all directions, generating the entire Universe. This happened about 13.8 billion years ago. After the explosion, the Universe began to cool and electrons, positrons, mesons, and the entire set of particles that are currently known were formed. Atoms were later created. Due to gravity, matter piled up to create clouds of the primordial elements. Some of these clouds began to rise stars and then galaxies formed.

The total resistance of a 15-ohm, an 65-ohm and a 35-ohm resistor connected in parallel

yanalaym [24]

Answer:

I think its 9.0397 Ohms

Explanation:

take the reciprocal of all the resistances: 1/15, 1/65, 1/35

then add them: = 151/1365

then reciprocal the answer: =1365/151

And chuck it on a calculator: =9.04 Ohms

I think this is right but I'm not entirely sure. Tell me if I'm right by the way!

An isolated conducting sphere has a 12 cm radius. One wire carries a current of 1.0000049 A into it while another wire carries a

tatuchka [14]

Answer:

it will take for the sphere to increase in potential by 1500 V, 503.71 s.

Explanation:

The charge on the sphere after t seconds is:

q = (1.0000049 - 1.0000000) t = 0.0000049 t

The voltage on the surface is

V = k * $\frac{q}{R}$ = k 0.0000049 t / R

solve for t

t = (R*V) / (0.0000049 k) = (0.12 * 1500) / (0.0000049 * $9e^{9}$ ) = 503.71 s
