C) is correct
series circuit - in the same path : current flow on one path so they are equal on each component and equal to the source's. voltage on each components may be different.
parallel circuit - between same nodes : voltage of the components are equal and equal to the source's. current on each components may be different.
Answer:
2.6 m
Explanation:
The work done by the bird is given by
where
F is the force exerted
d is the distance covered
In this problem, we know:
is the work
is the force
Solving the equation for d, we find the distance covered by the bird:
Answer:
the lens is located in the eye. by changing its shape, the lens changes the focal distance of the eye. in other words,it focuses the light rays that pass through it (and onto the retina) in order to create clear images of objects that are positioned
at various distances.
Answer:
Young modulus = 9.8 × 10⁹ N/m²
Explanation:
From the information given:
Stress = F/A
Stress = (10 × 9.8) / 0.001²
Stress = 9.8× 10⁷ N/m²
Strain = increase in length / initial length of wire
Strain = 0.02/ 2
Strain = 0.01
Now;
The Young modulus (Y)= stress/strain
Young modulus = (9.8 × 10⁷ N/m²) / 0.01
Young modulus = 9.8 × 10⁹ N/m²
