Answer: Option (c) is the correct answer.

Explanation:

Periodic table is basically a chart which depicts symbol of all the elements found in nature. And, these elements are represented along with their atomic number, and mass number.

Also, elements present in their respective period will tend to have same number of shells.

For example, potassium and scandium are both period 4 elements and they have four energy shells.

Thus, we can conclude that the year the element was discovered cannot be determined by analyzing the periodic table.

A glass window 0.33 cm thick measures 87 cm by 36 cm. How much heat flows through this window per minute if the inside and outsi

mojhsa [17]

Answer:

6.38 x 10^4 J

Explanation:

d = 0.33 cm = 0.33 x 10^-2 m, Area = 87 x 36 cm^2 = 0.87 x 0.36 m^2

ΔT = 14 degree C, t = 1 min = 60 second

K = 0.8 W / m K

Heat = K A ΔT t / d

H = 0.8 x 0.87 x 0.36 x 14 x 60 / (0.33 x 10^-2)

H = 6.38 x 10^4 J

A wave traveling in water has a frequency of 250 Hz and a wavelength of 6.0m. What is the speed of the wave?

vladimir2022 [97]

Since you are looking for the speed, you need to rearrange the formula which is f = speed / wavelength. That should give you speed = f (wavelength.) All you need to do next is to substitute the value to the following equation. speed = 250 Hz (6.0m) that should leave you with 1500 m/s which is very fast.
