Hope this helps !?!!!!!!!!!!!!
Answer:
A. min
Explanation:
= mass of earth = 6.0 x 10²⁴ kg
= Radius of earth = 6400 km = 6.4 x 10⁶ m
= Altitude above earth = 400 km = 0.4 x 10⁶ m
Radius of orbit of the space station around earth is given as
km
m
= Time period of orbit of space station
Here we can use Kepler's third law which is given as
Inserting the above values
sec
Answer:
Explanation:
The momentum of the 25 kg mass is
If this whole momentum of the object is transferred to the 5.0 kg object then according to the law of conservation of momentum, the momentum of the 25.0 kg object must be transferred to the 5.0 kg object:
One that can help you is:
ΔT=<span>T<span>Final</span></span>−<span>T<span>Initia<span>l
That is of course adding both tmepratures. There is one more that is a lil bit more complex
</span></span></span><span><span>Tf</span>=<span>Ti</span>−Δ<span>H<span>rxn</span></span>∗<span>n<span>rxn</span></span>/(<span>C<span>p,water</span></span>∗<span>m<span>water</span></span>)
This one is taking into account that yu can find temperature and that there could be a change with a chemical reaction. Hope this helps</span>
