Answer: it is easier to read in bright light than dim light.

Explanation:

The ray of light is the direction that is used by light in travelling through a medium. Rays that pass through a lens very close to the principle axis are more sharply focused than those that are very far from the axis.

Because of the fact that the rays are close to the principle axis, the spherical aberration helps us to understand the reason why it is easier for people to read in bright light than readin iin dim light.

The world energy consumption was about 6*10^22 J. How much area must a parallel plate capacitor need to store this energy Assume
Nastasia [14]

Answer:

A = 5 \times 10^{32} m^2

Explanation:

As we know that the energy stored in the capacitor is given as

Q = \frac{1}{2}CV^2

here we know that

Q = 6 \times 10^{22} J

also we know that

V = 5 Volts

now we have

6 \times 10^{22} = \frac{1}{2}C(5^2)

C = 4.8 \times 10^{21} F

now we know the formula of capacitance

C = \frac{\epsilon_0 A}{d}

4.8 \times 10^{21} = \frac{(8.85 \times 10^{-12})(A)}{1}

A = 5 \times 10^{32} m^2

60. The label on a box of cereal gives the mass of cereal in two units: 978 grams and 34.5 oz. Use this information to find a co
Anastaziya [24]

Answer : The mass of cereal in two units are, 34.815 oz and 978.075 grams respectively.

Explanation :

As there are two systems for measuring the units which are English and Metric system.

The Metric System measured the things in meters, grams, liters, etc and adds prefixes like kilo, milli and centi to the count orders of the magnitude.

The English system measured the things in feet, inches, pounds, mile, etc.

As we are given the mass of cereal in 978 grams that means 987 grams is in metric unit. Now we have to convert metric unit into English unit.

Conversion factor used :  (1 oz = 28.350 g)

As, 28.350 grams = 1 oz

So, 987 grams = \frac{987\text{ grams}}{28.350\text{ grams}}\times 1oz

                        =  34.815 oz

As we are given the mass of cereal in 34.5 oz that means 34.5 oz is in metric unit. Now we have to convert metric unit into English unit.

Conversion factor used :  (1 oz = 28.350 g)

As, 1 oz = 28.350 grams

So, 34.5 oz = \frac{34.5\text{ oz}}{1\text{ oz}}\times 28.350\text{ grams}

                  =  978.075 grams

Therefore, the mass of cereal in two units are, 34.815 oz and 978.075 grams respectively.
