Sin u
2. The expression of refractive index of a prism is given by the following relation:
(AP)
sin (4)
Assuming the error of A and D as AA and AD, express the error of u. Here 'A' is the angle of
the prism and 'D' is the angle of deviation.

Lets say that an object of a certain volume has a certin mass. what happens to its mass when you double its volume?

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?

Could someone . i have tried to solve myself but my calculation is off
