Answer:
b. producer
Explanation:
u cant have a food chain with out the smallest part. in other words if a deer had no grass to eat it wouldn't be on the food chain because it didn't have grass, than the lion would then starve and slowly die out after the deer ext (you get it).
Answer:
Explanation:
We shall apply law of conservation of momentum at the time of collision
Momentum before collision of both the pins = 1.8 x 3.6 + 0 = 6.48 kg m/s
Momentum after the collision of both the pins = 1.8 x .54 + 1.8 x v where v is velocity of second pin
So , according to law
6.48 = 1.8 x .54 + 1.8 x v
6.48 = .972 + 1.8 x v
v = 3.06 m /s to the right .
A rader gun will determine the speed.
Answer:
The mass of the ball is 0.23 kg
Explanation:
Given that
radius ,r= 3.74 cm
Density of the milk ,ρ = 1.04 g/cm³ = 1.04 x 10⁻³ kg/cm³
Normal force ,N= 9.03 x 10⁻² N
The volume of the ball V
![V=\dfrac{4}{3}\pi r^3](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3)
![V=\dfrac{4}{3}\times \pi \times 3.74^3\ cm^3](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B4%7D%7B3%7D%5Ctimes%20%5Cpi%20%5Ctimes%203.74%5E3%5C%20cm%5E3)
V= 219.13 cm³
The bouncy force on the ball = Fb
Fb = ρ V g
Fb + N = m g
m=Mass of the ball = Density x volume
m = γ V , γ =Density of the Ball
ρ V g + N = γ V g ( take g= 10 m/s²)
![\gamma =\dfrac{N+\rho V g}{V g}](https://tex.z-dn.net/?f=%5Cgamma%20%3D%5Cdfrac%7BN%2B%5Crho%20V%20g%7D%7BV%20g%7D)
![\gamma =\dfrac{9.03\times 10^{-2}+1.04\times 10^{-3}\times 219.13\times 10}{219.13\times 10}](https://tex.z-dn.net/?f=%5Cgamma%20%3D%5Cdfrac%7B9.03%5Ctimes%2010%5E%7B-2%7D%2B1.04%5Ctimes%2010%5E%7B-3%7D%5Ctimes%20219.13%5Ctimes%20%2010%7D%7B219.13%5Ctimes%2010%7D)
γ = 0.00108 kg/cm³
m = γ V
m = 0.00108 x 219.13
m= 0.23 kg
The mass of the ball is 0.23 kg
