Answer:

The mass of the other asteroid is m_2=6.49\times 10^9\ kg.

Explanation:

Given that,

Mass of one asteroid, m=5\times 10^8\ kg

The separation between two asteroids, r = 50,000 m

The force of gravity between asteroids, F=8.67\times 10^{-2}\ N

We need to find the mass of the other asteroid. The gravitational force acting between two masses is given by :

F=G\dfrac{m_1m_2}{r^2}

m_2 is the mass of other asteroid

m_2=\dfrac{Fr^2}{Gm_1}

m_2=\dfrac{8.67\times 10^{-2}\times (50000)^2}{6.67\times 10^{-11}\times 5\times 10^8}

m_2=6.49\times 10^9\ kg

So, the mass of the other asteroid is m_2=6.49\times 10^9\ kg. Hence, this is the required solution.

A light bulb radiates 110 nW of single-frequency sinusoidal electromagnetic waves uniformly in all directions. Calculate the ave
krek1111 [17]

Answer:

The intensity of the light from the bulb would be

3.501 x 10^{-6} W/m^{2}

Explanation:

Given

The Power = 110 n W = 110 x 10^{-9} W

the distance r = 50 mm = 50 /1000 = 0.05 m

The intensity can be obtained with the relationship below;

I = Power/area ......1

The area of the sphere would be used in this case since the bulb is spherical;    A=4πr^{2}

Putting it into equation 1, we have;

I = P/ 4πr^{2}

I =  110 x 10^{-9} / 4 x π x 0.05^{2}

I = 3.501 x 10^{-6} W/m^{2}

Therefore the intensity of the light from the bulb would be

3.501 x 10^{-6} W/m^{2}

What is statement can most likey be useing in the shock waves of atmoic bomb
Neko [114]

Answer:

The initial energy emission occurs by 80% or more in the form of gamma rays but these are quickly absorbed and dispersed mostly by air in little more than a microsecond, converting gamma radiation into thermal radiation (thermal pulse ) and kinetic energy (shock wave) which are actually the two dominant effects in the initial moments of the explosion. The rest of the energy is released in the form of delayed radiation (fallout or fallout) and is not always counted when measuring the performance of the explosion.

Explanation:

High altitude explosions produce greater damage and extreme radiation flux due to lower air density (photons encounter less opposition) and consequently a higher blast wave is generated.

What does it mean to say the mass is conserved during a physical change ?
Olin [163]
Mater doesn't just appear or disappeared. Chemical elements are still there just the connections and how it combines changes.

So what goes into your chemical eqation must still exist after the change.
