Answer:
0.64814 cm
Explanation:
= Refractive index of air = 1
= Refractive index of aqueous humor = 1.35
u = Object distance = 
v = Image distance = 25 mm
R = Radius of curvature of the cornea
Lens equation
Radius of curvature of the cornea is 0.64814 cm
90 watts = 0.09 KW
Energy = (power) x (time) =
(0.09) x (24) KWh
Cost = (energy) x (unit price) =
(0.09 x 24) x ($0.51) = <em>$1.10</em> per day (rounded)
(Those are very expensive kWh's.)
Answer: When a car is struck by lightning, the resulting electric field inside the car is zero.
Explanation:
Answer:
By heating all the water molecules which changes the thermal energy of the food
Explanation:
Average speed = (total distance covered) / (time to cover the distance)
Total distance = 69 km + 51 km = 120 km
Total time = 3 hrs + 2 hrs = 5 hrs
Average speed = (120 km) / (5 hrs) = 24 km/hr
