Answer: - 45000 N.s
Explanation: Impulse is equal to the change in momentum
J = Δp
To solve for impulse we calculate the change in momentum
Δp = m ( Δv)
= 1500 kg ( 10 m/s - 40 m/s)
= - 45000 N.s
Answer:
It is given that:
Density of material =ρ
radius of inner spherical shell = 
radius of outer spherical shell=
we know that the volume of sphere is 
Volume of the given spherical shell = 
Then mass of the spherical shell can be calculate as:
Mass, m=density/ volume
Answer:
Since ecosystems contain many different species of animals, plants, and other organisms, consumers have a variety of food sources. The pattern of feeding represented by these interconnected and branching food chains is called a food web. Figure 36-3 shows how food chains within a food web are interconnected.
