if waves on the lake have a frequency of 3 hertz and a wavelength of 4 meters,what is the speed of the waves?

You have to use the equation v=λf
v is the velocity of the wave
λ is the wave length of the wave (how far the wave goes in one cycle)
f is the frequency of the wave (how long one cycle is) 

V=4m×3Hz
v=12m/s

Hz stands for s⁻¹ which is why the final units is m/s

I hope this helps.  Let me know if anything is unclear.

Determine the change in volume that takes place when a 2.00 L sample of N2 gas is heated from 250 C to 500 C.
Effectus [21]

Answer:

V₂ = 2.96 L

Explanation:

Given data:

Initial volume = 2.00 L

Initial temperature =  250°C

Final volume = ?

Final temperature = 500°C

Solution:

First of all we will convert the temperature into kelvin.

250+273 = 523 k

500+273= 773 k

According to Charles's law,

V∝ T

V = KT

V₁/T₁ = V₂/T₂

V₂ = T₂V₁/T₁

V₂ = 2 L × 773 K / 523 k

V₂ =  1546 L.K / 523 k

V₂ = 2.96 L

Which color of light is diffracted at a greater angle from a diffraction grating, red or yellow?
Anit [1.1K]
The color of light that will be diffracted at a greater angle from a diffracting grating is THE YELLOW COLOR.
This is because, the degree of diffraction depend on the wavelength of light and light color with shorter wavelength are diffracted at a larger angle than those with longer wavelengths. The wavelength of the yellow color is much more smaller than that of the red color.

All organic compound soluble in WATEe and conduct electrically ​
Delvig [45]

No

Explanation:

Not all organic substances are soluble in water and will not conduct electricity. Only polar organic compounds are soluble in water and will conduct electricity.

  • The general rule of solubility is that like dissolves likes.
  • Polar compounds will only dissolve other polar compounds too. Water is a polar solvent.
  • Non-polar compounds will only dissolve in non-polar compounds too.
  • Since water is a polar organic compound, only polar organic compounds will dissolve in it.
  • Not all organic compounds are polar.
  • When a compound dissolves in water, it produces ions that makes it able to conduct electricity.
  • Fats and oil are insoluble in water

How does the heat content of the reaction change in the process of photosynthesis when a glucose molecule is formed?
patriot [66]

In the process of photosynthesis, when a glucose molecule is formed, THE HEAT CONTENT OF THE REACTION INCREASES, THUS, THE VALUE OF Q IS POSITIVE.

There are two types of chemical reaction, these are exothermic and endothermic reaction. Exothermic reactions are those reactions that gives off heat when they are occurring while endothermic reactions are those reactions that absorb heat from their environment during the course of reaction. Photosynthesis is an endothermic reactions; it absorbs energy from the environment when it is occurring, thus, the heat content of the product is always more than that of the reactants. The heat content of compounds are represented by letter q. For photosynthesis, q is positive, because there is an increase in the heat content of the product [glucose] formed.
