Q. 1: The far distance a person can see an object is at a distance of 50 cm from the eye but she wants to see an object at infinity. What types of lens is required to make her vision correction? Calculate the optical power of her lens.
Q 2: The near point a person can see an object is at a distance of 50 cm from the eye but he wants to see object at the least distance of distinct vision. What types of lens is required for him to correct his vision? Calculate the optical power of his lens.

94. Choose the false statement:
A. The actions of the muscles required for inspiration serve to increase the volume of the thoracic cavity; as a result, alveolar pressure decreases relative to atmospheric pressure.
B. Cholecystokinin is released by enteroendocrine cells in response to fat in the gut; this hormone triggers the release of digestive juices from stomach, increases gastric (stomach) motility and the rate of stomach emptying.
C. Chylomicrons carry dietary fats absorbed across the gut; these are manufactured by intestinal epithelial cells, are then transferred to the lymphatic circulation and are finally delivered into the blood venous circulation near the heart.

let R be a region bounded by x = 0 and x =1 and y = 0 and y = 1. Suppose the density is given by 1/y+1.Notice that R is denser near the x axis. As a result we might expect the centre of mass to be below the geometric center(1/2,1/2). Also since the density does not depend on x we do expect moment of inertia about the x axis to be 1/2. verify the moment of inertia about x is 1/2 and compute the value of the moment of inertia about the y axis

1. After a century-long ‘discovery’ about motivation, have we reached the promised land of healthy, productive, and satisfied employees? What does your own experience during the lockdown period tell you? Which theoretical approach did you find particularly helpful in thinking about your own motivation? Discuss.

A. R found a box while jogging near her home. In the box was $100,000. R reported the find to the police, but because the owner could be found, R was allowed to keep the money.
B. W purchased 10 acres of land for $100,000. Shortly after the purchase it was discovered that oil was present beneath the ground. The value of the land immediately increased to $5,000,000.
C. E borrowed $50,000 from a bank using his home as collateral for the loan. The home was worth $900,000.

A company just purchased a piece of equipment for $650,000. The economic reality is that the asset has an estimated useful life of ten years and will be worth $75,000 at the end of its useful life. Straight-line is the appropriate depreciation method.
1. Using excel, compute the depreciation schedule for this asset. How much depreciation expense will be taken each year? What will the asset's book value be at the end of Year 6?
2. If the company wanted to increase its earnings in the near term, how could it accomplish this by using their estimate of:
A) Useful life?
B) Salvage value?

A thin-walled hollow cylinder with mass m1 and radius R1 rolls without slipping on the inner wall of a larger thin-walled hollow cylinder with mass m2 and radius R2 >> R1. Both cylinders' axes are aligned and horizontal, and some magical mechanism ensures this perfect friction contact between them. Unfortunately for you, the larger cylinder rolls without slipping on a horizontal surface. Describe the motion including small oscillation frequencies near any equilibria if the systems is released from rest with the inner cylinder at some angle α0.

Suppose you perform the following multiple regression: Y = B0 + B1X1 + B2X2 + B3X3. You find that X1 and X3 have a near perfect correlation. How would you conclude on the utility of your regression result? This is a problem of multicollinearity which renders the entire regression invalid. This is a problem of multicollinearity which nevertheless does not invalidate the utility of the model as a whole This is NOT a regression problem and inferences made using the model and the respective coefficients remain valid. This is a problem of multicollinearity. However inferences made concerning the individual contribution of the model coefficients remain valid
