Three children are playing in a pool in the back yard. One child is at the far left end of the pool and is splashing. A second c

hild is laying on a float in the middle of the pool. The third child is at the far right of the pool and begins splashing as well. The child on the float in the middle of the pool notices that when both of her friends are splashing on opposite sides of the pool, she is raised much higher on her float as the waves lift her up. What phenomenon is the child in the middle of the pool experiencing?
A) Doppler effect
B) Seismic impact
C) Destructive interference
D) Constructive interference

The answer is; D

When both kids splash at both ends of the pool, the waves formed from the different direction travel and meet in the middle of the pool (since they are traveling with the same speed). When the waves meet, they interact and form constructive waves. This means that when a crest meets a crest, the height doubles. This also occurs for the troughs. Therefore the sizes of the waves at the middle are twice the individual waves.

An atom has a mass number of 30 and 16 neutrons. What is the atomic number of this atom?
Lana71 [14]
The mass number is the number of protons plus the number of neutrons. Since there are 16 neutrons, there are 14 protons. This also corresponds to the atomic number, so this atom's atomic number is 14 which is also Silicon

To plot the calibration curve, you need to prepare iron solutions with known concentrations and measure their absorbance.
kap26 [50]

To plot the calibration curve, you need to prepare iron solutions with known concentrations and measure their absorbance. You need to pipet 0 mL of the diluted solution to have 0.00 mg of iron.

In spectrophotometry, to plot the calibration curve, you need to prepare solutions with known concentrations and measure their absorbance.

We have a standard iron solution with a concentration of 0.2500g/L of pure iron (C₁). We pipet 25.00mL (V₁) of this standard iron solution into a 500mL (V₂) volumetric flask and dilute up to the mark with distilled water.

We can calculate the concentration of the diluted solution (C₂) using the dilution rule.

C_1 \times V_1 = C_2 \times V_2\\\\C_2 = \frac{C_1 \times V_1}{V_2}  = \frac{0.2500 g/L \times 25.00 mL}{500 mL} = 0.0125 g/L

Then, if we wanted to prepare the blank, that is, the solution that contains the same matrix but not the analyte, and whose concentration in iron is 0.00 mg/L, we wouldn't pipet any of the diluted solution.

To plot the calibration curve, you need to prepare iron solutions with known concentrations and measure their absorbance. You need to pipet 0 mL of the diluted solution to have 0.00 mg of iron.

How many mg are there in a 5.00 grain aspirin tablet? I grain = 0.00229 oz. There are 454 g/lb.
ehidna [41]

Answer: 325 mg

Explanation:

Grains ---> ounces -----> pounds -----> grams -----> mg

5 gr x (0.00229 oz / 1 gr) x (1 lb / 16 oz) x (454 g / 1 lb) x (1000 mg / 1 g) = 325 mg
