What is the approximate period of this wave?15 centimeters
15 seconds
10 seconds
5 seconds

Answers

Answer 1

Answer:

Answer: 10 seconds

A period is the time needed to complete one cycle. Period can be obtained by dividing the total time over the total number of waves.

T (period) = 60 secs / 6 waves

T = 10 secs

All life that we know of is based on carbon. Carbon's ability to form many chemical bonds is an important characteristic that allows it to form the basis of life. Identify two other elements that can probably also form a large number of bonds and that probably have similar properties to carbon.

Starch and cellulose have the same substance but different structures. They are both polysaccharides. The basic unit of a polysaccharide is the glucose. Glucose, which contains carbon, hydrogen, and oxygen, have two forms. The alpha-glucose with an alcohol group attached to carbon 1 is down and the beta-glucose with the alcohol group attached to carbon 1 is up. Starch is the alpha-glucose while cellulose is the beta-glucose. Starches are linked into a straight chain whereas the cellulose are connected like a pile of stack paper. When the human body eats starch, it can digest the starch but not the cellulose because it has no enzyme that can break it down.

Which of the following is an advantage of geothermal energy?a. Scarcity of suitable sites

b. Odor pollution

c. Low land use

d. Possible depletion of reservoirs

Answers

Geothermal energies are widely used for various domestic and power supply processes. The lower usage of land is an advantage of geothermal energy. Hence, option (c) is correct.

What is Geothermal Energy?

The energy generated in the form of heat from the Earth is known as geothermal energy. Rocks and Fluids beneath the Earth's crust are the major sources of these kinds of energies.

The advantages of geothermal energy are as follows -

It is a renewable source of energy that is clean and sustainable.
No emission produced, geothermal plants do not produce greenhouse gases like fossil fuels plants. Therefore, it is also known as an eco-friendly source of energy.
It can be pumped back to the ground is among other advantages.

Thus, we can conclude that the lower usage of land is an advantage of geothermal energy. Hence, option (c) is correct.

b. resistance
c. potential difference
d. induction

Answers

The question is poorly worded, and makes it harder for the student to learn the basics of the subject. "Potential Difference" is the difference in electrical potential between two places in an electric field ... not in electrical potential energy.

If a certain mass of mercury has a volume of 0.002 m3 at a temperature of 20°C, what will be the volume at 50°C? A. 0.002010812m3
B. 0.004021624m3
C. 0.002021624m3
D. 0.000010812m3

Answers

As per the question the volume of mercury is given as 0.002 m^3 at 20 degree Celsius.

We are asked to calculate the volume of the mercury at 50 degree Celsius.

This problem is based on thermal expansion of matter.

Let us consider the initial and final volume of the mercury is denoted as -

$v_(1) \ and\ v_(2)$

Let the initial and final temperature of the mercury is denoted as -

$T_(1)\ and \ T_(2)$

As per question

$v_(1) =0.002 m^3$ $v_(2) =?$

$T_(1) =20^0 C$ $T_(2) =50^0 C$

The change in temperature is

$T_(2) -T_(1)$

$= 50^0 C -20^0 C$

$= 30^0 C$

Mercury is a fluid.So we have to apply volume expansion of liquid .

The coefficient of of volume expansion of mercury $[ \gamma ]$ at 20 degree Celsius is 0.00018 per centigrade.

As per volume expansion of liquid,

$V_(T) = v_(1) [1 +\gamma [T_(2) -T_(1) ]]$

Here $V_(T)$ is the volume at T degree Celsius.

Hence volume at 50 degree Celsius is calculated as-

$v_(2) =v_(1) [1+\gamma[50-30]]$

$= 0.002[1+0.00018*30]$

$=0.0020108m^3$ [ans]

As per the options given in the question ,option A is close to the calculated value. So option A is right.

The answer to this question lies in understanding the Combined Gas Law in chemistry, which combines Boyle's, Charles', and Gay-Lussac's gas laws. This law shows the relationship between pressure, volume, and temperature of gases and is represented by the equation P1V1/T1 = P2V2/T2. Changes in pressure (P) and volume (V) are directly proportional to one another, but these are inversely proportional to changes in temperature (T). This question must assume that pressure is constant, so the Ps cancel out and the equation becomes V1/T1 = V2/T2. Additionally, temperature should be converted to Kelvins (K) by adding 273 to the temperature in Celsius (so 20 C = 293 K, and 50 C = 323 K). If V1 = 0.002 and T1 = 293 and T2 = 323, then we solve the equation as V2 = T2*V1/T1 or V2 = (323*0.002)/293, so the answer is approximately equal to 0.0022... or answer (C).
