Am not really sure but what i see is D
<u>Answer:</u>
total mass = 410 g
<u>Explanation:</u>
density = 1.8 g/cm³
volume = 200 cm³
density = mass / volume
mass (of liquid) = density x volume
= 1.8 x 200
= 360 g
total mass (beaker + liquid) = 50 + 360 = 410 g [Ans]

Answer:
Explanation:
Given
mass of steel ball 
initial speed of ball 
Final speed of ball 
(in upward direction)
Impulse imparted is given by change in the momentum of object
therefore impulse J is given by
so magnitude of Impulse =4 N-s
