Answer:

Explanation:
From the question we are told that:
Velocity 
Force of friction f = 0
Angle 
Generally the equation for Radius of curvature is mathematically given by



A parallel plate capacitor can store electric charge and
electrical energy, and if the plates are far enough apart,
you can store your lunch in there too.
Answer:
Explanation:
Near point = 56 cm .
near point of healthy person = 25 cm
person suffers from long sightedness
convex lens will be required .
object distance u = 25 cm
image distance v = 56 cm
both will be negative as both are in front of the lens.
lens formula
I/v - 1 / u = 1/f
- 1/56 +1/25 = 1/f
- .01785 + .04 = 1/f
1/f = .02215
f = 45.15 cm .
Answer:
Assuming there are 28 days in each month,
750W = 0.75kW
Cost of electric bill = 0.75 × 8 × 28 × $0.23
= $38.64
