Answer:
A. 4.82 cm
B. 24.66 cm
Explanation:
The depth of water = 19.6 cm
Distance of fish = 6.40 cm
Index of refraction of water = 1.33
(A). Now use the below formula to compute the apparent depth.
(B). the depth of the fish in the mirror.
Now find the depth of reflection of the fish in the bottom of the tank.
The SI unit of force is the<em> Newton</em> .
1 Newton is the force that accelerates 1 kilogram of mass at the rate of 1 meter per second-squared.
1 pound of force is roughly 4.45 Newtons of force.
So 1 Newton of force is roughly 3.6 ounces of force.
1 kilogram of mass weighs about 9.81 Newtons on Earth. That's the same as 2.205 pounds.
Answer:
The answer is B 5.0 Volts
Explanation:
I'm using the formula from Ohm's Law like you mentioned for my answer.
V=IR
V=0.050 amps x 100 ohms of resistance
With this you'll have your answer!
Answer:
The velocity in the pipe constriction will increase. (option A)
Explanation:
Assuming the flow to be subsonic, that is, a flow speed less than the speed of the sound (around 323 m/s for standard condition of 15 °C), in a constriction, the pipe sectional area is reduced then, to satisfy the fluid continuity equation, the flow's speed must increase.
The continuity equation states that the amount of fluid must be conserved:
m=p.A.V=k=constant
Where m is the mass rate, p the density, A the sectional area and V the fluid's speed. If we consider incompressible flow (p constant):
m=A.V=k=constant
Therefore by applying the continuity equation before and at the constriction:
A.V=Ac.Vc
(the subscript c related to the constriction)
Solving for Vc:
Vc=V.(A/Ac)
As A/Ac must be bigger than 1 because of the constriction therefore
Vc=V.(Ac/A>1)>V.
The velocity in the constriction is greater than before the constriction.
