True. Solvents are always materials that contain the solute. Water contains the salt, in this instance.
Answer:
A) 4.3 m/s
Explanation:
M = mass of the cannon = 1200 kg
m = mass of the cannonball = 100 kg
v = speed of the cannonball after the fire = 52 m/s
V = speed of cannon after fire
Since the cannon and cannonball were at rest before fire, total initial momentum will be taken as 0
Using conservation of momentum
0 = m v - M V
M V = m v
inserting the values
(1200) V = (100) (52)
V = 4.3 m/s
