Answer:
4.5kgm/s
Explanation:
Change in momentum is expressed as
Change in momentum = m(v-u)
M is the mass
V is the final velocity
u is the initial velocity
Given
m=0.45kg
v = 30m/s
u = 20m/s
Substitute
Change in momentum = 0.45(30-20)
Change in momentum = 0.45×10
Change in momentum = 4.5kgm/s
Answer: the particles are more orderly in region 1
Explanation: region 1 is when the substance is a solid and as it is heated the particles move further apart and have more kinetic energy.

9 mm = 0.009 m in diameter
Cross-sectional area 
Let the tensile modulus of Nickel 
.
The elongation of the rod can be calculated using the following formula:
Genes. you inherit 50% from your mom and dad. I believe that is the answer....
Do 112m /29s which it will be 3.862 which if you round it, it will be 3.86 m/s
