Answer:
A. Equal to and Opposite
Explanation:
when there is no External force acting on the system of bodies then Net momentum of the system is Conserved .
Given that there are 2 bodies
Let P₁ as first object's momentum
P₂ as second object's momentum.
Total Momentum =P₁ + P₂
As there is no external force acying on the system
Change in the Total momentum is zero
so,
0 = Δ P₁ + ΔP₂
ΔP₂ = -ΔP₁
negative sign indicates opposite direction.
Both are of equal magnitude.
Answer:
Explanation:
We have given that the battery has an internal emf of 9 volt
So E = 9 volt
Capacitance 
It is given that on the terminal voltage is only 80% of potential difference
So V = 0.8×9 = 7.2 volt
We know that energy stored in the capacitor is given by
Answer:
<em>Zoe caught a lower ratio of catfish to trout on the second day of her fishing trip</em>
Explanation:
<u>Proportions and Ratios</u>
To compare two quantities we can perform them some 'test' operations like subtraction or division. If we subtract the first quantity from the second quantity, the difference can be positive if the second is greater, negative if the first is greater, or zero if they are equal.
A similar situation comes if we divide the last by the first. If the ratio (division) is greater than one, then the last quantity is greater than the first if it's less than one, the first is greater, and if it's exactly one, they are equal.
Zoe caught 9 catfish and 6 trout on her first day. It produces a ratio of 9/6=1.5 catfish to trout relation. The second day she caught 17 catfish and 13 trout, which gives us a ratio of 17/13=1.3 catfish to trout.
Based on the ratios we can say Zoe caught a lower ratio of catfish to trout on the second day of her fishing trip
