Answer:

Explanation:

Nuclear Fission -

The process of the splitting of atom , by radioactive decay process or by any collisional impact .

Sun contains many radioactive isotopes like , thorium , uranium , etc .

The nuclear fission process is an intrinsic property of the radioactive nuclides.

Nuclear Fusion -

The process , where two or more than two atomic nuclei combines to form one or more different atomic nuclei and subatomic particles .

The energy released in both the process is almost same ,

But on the surface of Sun , hydrogen is abundantly present , hence , hydrogen fusion is possible , so the dominant source of energy on the sun is Fusion .

The speed or celerity of deep-water waves... A. increases with increasing water depth B. increases as water becomes blue in colo

antoniya [11.8K]

Answer:

Explanation:

The speed or celerity of deep-water waves increases with increasing water depth.

With increase in depth, the pressure inside the increases as p=ρgh.

And with this increase in pressure force associated with waves increase because force is directly proportional to the pressure. Now greater the force greater will be accleration and greater velocity is obtained.

A very long stick ruled with meter markings is placed in empty space. A spaceship of rest length L = 100 m runs lengthwise along

alexira [117]

Answer:

Meter marks are on cut-off portion of stick is 100 - 60 = 40 m

Explanation:

Given data:

Spaceship length of L = 100 m

Relative velocity between the ship and stick is given as

$v = \frac{4}{5} c$

The observed length observed by the outside observer is

$L' = L\sqrt{1 -\frac{v^2}{c^2}}$

putting all value to get observe length

put $v = \frac{4}{5} c$

$L ' = 100\times \sqrt{1 - \frac{(4/5)^2c^2}{c^2}$

L' = 60 m

Meter marks are on cut-off portion of stick is 100 - 60 = 40 m

A space probe on the surface of Mars sends a radio signal back to the Earth, a distance of 9.75 ✕ 107 km. Radio waves travel at

Mars2501 [29]

Answer:

It takes 325 seconds for the signal to reach Earth.

Explanation:

First, you must make a unit change from m/s to km/s in order to make a comparison with the distance of the radio signal sent to Earth. For that, you know that 1 m is 0.001 km. So:

$3*10^{8} \frac{m}{s} =3*10^{8}\frac{0.001 km}{s}=300,000\frac{km}{s}$

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. That is, what is intended with it is to find the fourth term of a proportion knowing the other three. Remember that proportionality is a constant relationship or ratio between different magnitudes.

If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other) , the direct rule of three must be applied. To solve a direct rule of three, the following formula must be followed:

a ⇒ b

c ⇒ x

$x=\frac{c*b}{a}$

In this case, the rule of three is applied as follows: if by definition of speed, 300,000 km of light are traveled in 1 second, 9.75 * 10⁷ km in how long are they traveled?

$time=\frac{9.75*10^{7}km*1second }{300,000 km}$

time=325 seconds

<em><u> It takes 325 seconds for the signal to reach Earth.</u></em>
