Answer:
Explanation:
A ) Index of refraction = real depth / apparent depth
real depth = 7.8 cm ; Index of refraction = 1.33
1.33 = 7.8 /apparent depth
apparent depth = 7.8 / 1.33
= 5.86 cm
B )
Distance of fish fro mirror = 20.6 - 7.8 = 12.8 cm
Image will be formed 12.8 cm behind the mirror.
Distance of image from the water surface = 20.6 +12.8
= 33.4 cm
Real depth of image = 33.4
Apparent depth of image = 33.4 / 1.33
= 25.11 cm
Answer:
36 m³
Explanation:
From gas laws, at a constant temperature, the product of volume and pressure are directly proportional hence expressed as p1v1=p2v2 where p is pressure while v represent volume. Subscripts 1 and 2 represent the initial and respectively. Making v2 the subject then
Substituting 120 kpa for P1, 12m³ for V1 and 40 kpa for p2 then
Therefore, the volume will be 36 m³
Answer:
0.85V
Explanation:
The emf is calculated by using the Lenz's Law
But for this case we have that the magnetic field is constant. Hence we have
where we have taken that the intial time is t1=0
