How is light used to study space? IN YOUR OWN WORDS

sineoko [7]

Well, all the words are common, but I try to answer in my way. The way how light is used to study space is finding distance between the planets, which is called a light year. According to the <span>scientist's beliefs the space is but a vaccum and the only body that can travel through it is light, that's why light is very importand for discovering space.

A thin ring of radius 73 cm carries a positive charge of 610 nC uniformly distributed over it. A point charge q is placed at the

kow [346]

Answer:

q = - 93.334 nC

Explanation:

GIVEN DATA:

Radius of ring 73 cm

charge on ring 610 nC

ELECTRIC FIELD p FROM CENTRE IS AT 70 CM

E = 2000 N/C

Electric field due tor ring is guiven as

$E = \frac{KQx}{[x^2+ R^2]^{3/2}}$

$E = \frac{9\time 10^9 \times 610\times 10^[-9} 0.70}{(0.70^2 + 0.73^2)^{3/2}}$

E1 = 3714.672 N/C

electric field due to point charge q

$E =\frac[kq}{x^2}$

$E = \frac{9\times 10^9 \times q}{0.70^2}$

$E2 = 1.837\times 10^{10}\times q$

now the eelctric charge at point P is

E = E1 + E2 $2000 = 3714.672 + 1.837\times 10[10} \times q$

solving for q

q = - 93.334 nC

Lithium atoms split when they are blank with a stream of protons

lions [1.4K]

The answer is; bombarded

John Cockcroft and Ernest Walton split the lithium atom using accelerated protons. The atomic nuclei were split and the physicist observed alpha particles (two protons and two neutrons bound together into a particle identical to a helium-4 nucleus) as one of the products. The experiment also led to the discovery of the neutron and positron subatomic particles.
