A biconvex lens is one in which both surfaces of the lens bulge outwards. Suppose you had a biconvex lens with radii of curvature with magnitudes of R 1= 10cm and R 2 = 15cm. The lens is made of glass with index of refraction n=1.5. We will employ the convention that R 1 refers to the radius of curvature through wich light will enter the lens, and R 2 refers to the radius of curvature from which the light will exit the lens.Is this lens converging or diverging?What is the focal length of this lens in air?

and if you take fewer, you will have less calories, so less energy.
Final answer:
False. A negative energy balance happens when you eat fewer calories than needed and expend more energy, leading to weight loss. A positive energy balance happens when you eat more calories than needed and expend less energy, leading to weight gain.
Explanation:
False. Energy balance refers to the relationship between the energy you take in from foods and the energy you expend in daily activities. Negative energy balance occurs when the energy you expend is more than the energy you take in (fewer calories eaten than needed), leading to weight loss. Conversely, a positive energy balance happens when you consume more energy than you expend (more calories eaten than needed), resulting in weight gain.

C) 2.63%
D) .0263%
Answers
Answer:
2.63 %.
Explanation:
Given that,
The calculated value of the specific heat of water is 4.29 J/g.C
Original value of specific heat of water is 4.18 J/g.C.
We need to find the student's percent error. The percentage error in any quantity is given by :
So, the student's percent error is 2.63 %.
The student's percent error in measuring the specificheat of water is 2.63%.
The specificheat is the amount of heat required to increase the temperature of 1 kg of mass by 1 degree Celsius.
Given:
Experimental Value = 4.29 J/g°C (student's measured value)
Accepted Value = 4.18 J/g°C (literature value)
The percent error can be calculated using the formula:
Percent Error = ((Experimental Value - Accepted Value) / Accepted Value)×100
Substitute the given values in the above formula and calculate the percenterror:
Percent Error = [(4.29 - 4.18) / 4.18] × 100
Percent Error = (0.11 / 4.18) × 100
Percent Error = 2.63%
The student's percent error in measuring the specificheat of water is approximately 2.63%.
Therefore, the student's percent error in measuring the specific heat of water is 2.63%.
