Explanation:
It is given that,
Mass of platinum bar, m = 750 g
Length of the bar, l = 5 cm
Breadth of the bar, b = 4 cm
Width of the bar, h = 1.5 cm
Volume of the bar, 
We need to find the density of the platinum bar. The density of any substance is given by :
So, the density of the platinum bar 
. Hence, this is the required solution.
Momentums equation is just p=mv
mass times velocity so 50x200
p=10,000
Answer:
2 * 10^4
Explanation:
(3 * 10^4)(4 * 10^4) / (6 * 10^4)
= (12 * 10^8)/(6 * 10^4)
= 2 * 10^4
