Explanation:

Given parameters:

mass of bullet 1 = 0.0014kg

velocity of bullet 1 = 396m/s

mass of bullet 2 = 7.1 x 10⁷kg

velocity of bullet 2 = 13m/s

Unknown;

Comparing the kinetic energy

Solution:

Kinetic energy is the energy due to the motion of a body.

K.E = $\frac{1}{2}$ m v $^{2}$

bullet 1:

K.E = $\frac{1}{2}$ x 0.0014 x 396 $^{2}$ = 109.8J

bullet 2:

K.E = $\frac{1}{2}$ 7.1 x 10⁷ x 13 $^{2}$ = 6 x 10⁹J

The second bullet has more kinetic energy than the first one.

A few years ago, an X-ray telescope detected a source called Cygnus X-3, whose intensity changed with a period of 4.8 hours. Thi

alina1380 [7]

Answer:

Explanation:

The star is revolving the black hole like earth revolves around the sun .so time period of rotation T is given by the following relation

T² = $\frac{4\pi^2\times R^3}{GM }$ , R is distance between black hole and star , M is mass of black hole

Given T = 4.8 hours

4.8² = $\frac{4\pi^2\times R^3}{GM }$

Using the same equation for earth sun system

24² = $\frac{4\pi^2\times (50R)^3}{GM_s }$ , Ms is mass of the sun and 50R is distance between the sun and the earth .

Dividing the equation

$(\frac{4.8}{24})^2$ = $\frac{M_s}{M}\times\frac{1^3}{50^3}$

$\frac{M}{M_s}$ = 2x 10⁻⁴

erastova [34]

Answer:

Explained below.

Explanation:

Conductors can be defined as materials that permit electricity to flow through them easily.

Now, metals have a molecular structure that makes them good conductors because electrons in the atoms of these conductors tend to move freely from one atom to the other. So a majority of metals make good conductors because these metals tend to hold their electrons loosely. In short, it can help engineers make powerful batteries because then it means that they are capable of giving much more electrical energy since nowadays, advanced batteries make use of ion charges for the batteries.
