Frequency is represented by f in the formula v=fπ. Where π is wavelength , f is frequency and v is velocity. Frequency is the number of waves passing per unit time.

If A + B → C + D You start with 50 g of A and 30 g of B and 40 g of C are produced, how many g of D would also be produced?

vesna_86 [32]

Answer:40g of D

Explanation:

Law of conservation of matter:

Matter can neither be created nor be destroyed but can change from one form to another.

The total of the reactants must be equal to that of the product.

A+B=>C+D

50g+30=40g+D

80g=40g+D

D=80-40

D=40g

A balloon with a volume of 2.0 L is filled with a gas at 3 atmospheres. If the pressure is reduced to 0.5 atmospheres without a

creativ13 [48]

Answer:

V2 = 12 L

Explanation:

Given the following data;

Initial volume = 2L

Initial pressure = 3 atm

Final pressure = 0.5 atm

To find the new volume V2, we would use Boyles' law.

Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.

Mathematically, Boyles law is given by;

$PV = K$

$P_{1}V_{1} = P_{2}V_{2}$

Substituting into the equation, we have;

$3 * 2 = 0.5V_{2}$

$6 = 0.5V_{2}$

$V_{2} = \frac {6}{0.5}$

$V_{2} = 12$

V2 = 12L

Therefore, the new volume is 12 Liters.

ASHA 777 [7]

Answer:

Explanation:

1. diffusion is a physical process when there is random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration.

2. Osmosis is the diffusion of water where molecules of water move passively (without energy) from high concentration to low concentration. eg: the way water rushes into a sponge.

3. Active transport moves particles from low to higher concentration. The difference between diffusion and active transport is diffusion does not require energy (eg: oxygen moving from the airways to the lungs - there is very little oxygen in the lungs but lots in the air). whereas active transport does require energy (eg: when plants take up nutrients from the soil. The soil does not have a large concentration of nutrients, but the plant does)
