Answer:
767.6 m/s
Explanation:
We consider momentum in both x and y components
Since momentum, p=mv where m denote mass while v is velocity then
In the y direction
3m*288=279m+my
y=585 m/s
In the x direction and taking right as positive then
3m*288=367m+mx
x=497 m/s
The resultant gives the velocity of the third fragment

Answer:
16.5% that of on earth
Explanation:
from google:
Your weight on the Moon is 16.5% what you would experience on Earth. In other words, if you weighed 100 kg on Earth, you would weigh a mere 16.5 kg on the Moon.

gas
Explanation:
the molecules in the substance are always moving around making them the most active
Answer:
t = 134834.31 years
Explanation:
First we find the speed of the ship:
v = 0.890 c
where,
v = speed of the ship = ?
c = speed of light = 3 x 10⁸ m/s
Therefore, using the values, we get:
v = (0.89)(3 x 10⁸ m/s)
v = 2.67 x 10⁸ m/s
Now, we find the distance in meters:
Distance = s = (1.2 x 10⁵ light years)(9.461 x 10¹⁵/1 light year)
s = 11.35 x 10²⁰ m
Now, for the time we use the following equation:
s = vt
t = s/v
t = (11.35 x 10²⁰ m)/(2.67 x 10⁸ m/s)
t = (4.25 x 10¹² s)(1 h/3600 s)(1 day/24 h)(1 year/365 days)
<u>t = 134834.31 years</u>
