Answer:
d. image is real is incorrect.
Explanation:
plane mirror always forms virtual and erect image, it can't be real because the image is not formed by the actual intersection of the rays.
Answer:
The vibrational frequency of the rope is 5 Hz.
Explanation:
Given;
number of complete oscillation of the rope, n = 20
time taken to make the oscillations, t = 4.00 s
The vibrational frequency of the rope is calculated as follows;
Therefore, the vibrational frequency of the rope is 5 Hz.
Answer:
d) 2.12 V
Explanation:
E =E° - RT/nF log 1/H⁺ x HSO₄⁻
E = 2.08 - ( .059/2 X log 1/4.5x4.5 )
2.08 - (-0.038 ) = 2.118 =2.12 V
Answer:
Explanation:
We know that the work could be calculate dby:
W =
where is the component of the force in the direction of the
displacement. and d is the displacement.
So, the total work () is:
Where is the force done by the first tugboat, is the angle of the force, d is the displacement and is the force done by the second tugboat.
