Answer:
Explanation:
The speed of the astronaut can be found with the help of law of conservation of momentum .
mv = MV , M is mass of astronaut , m is mass of object thrown , v is velocity of object thrown and V is velocity of astronaut.
Putting the values
77.5 x V = .94 x 12
V = .14554 m /s
This will be the uniform velocity of astronaut.
Distance to be covered = 37.3 m
time taken = distance / velocity
= 37.3 / .14554
= 256.28 s
= 4.27 minutes.
Answer:120.3676
Explanation: using the molecular calculator and molar mass of MgSO4. hope this helps!
The answer is A , the forces are balanced
Answer:
vertical velocity = 33.55 m/s
Explanation:
sin (34) = v/60
sin (34) x 60 = v
33.55 m/s = v
