Answer:
2000 kg m/s
Explanation:
The momentum of an object is a vector quantity whose magnitude is given by
![p=mv](https://tex.z-dn.net/?f=p%3Dmv)
where
m is the mass of the object
v is the velocity of the object
and its direction is the same as the velocity.
In this problem, we have:
- Spaceship 1 has
m = 200 kg (mass)
v = 0 m/s (zero velocity)
So its momentum is
![p_1 =(200)(0)=0](https://tex.z-dn.net/?f=p_1%20%3D%28200%29%280%29%3D0)
- Spaceship 2 has
m = 200 kg (mass)
v = 10 m/s (velocity)
So its momentum is
![p_2=(200)(10)=2000 kg m/s](https://tex.z-dn.net/?f=p_2%3D%28200%29%2810%29%3D2000%20kg%20m%2Fs)
Therefore, the combined momentum of the two spaceships is
![p=p_1+p_2=0+2000=2000 kg m/s](https://tex.z-dn.net/?f=p%3Dp_1%2Bp_2%3D0%2B2000%3D2000%20kg%20m%2Fs)
Answer: 7
Explanation:
How many pieces are in a ROLO tube?
each classic roll of ROLO….has seven individually wrapped pieces. Tuck it in your lunchbox, bag or desk drawer and get your roll on.
Since the wires are made up of the same material, the resistivities will be the same.
Idk but i hope you figure it out :)
