Answer:
The current of the toaster is 3.93A
Explanation:
Using the GRASS method:
G: Given: The information that is given is that we have 28Ω of Resistance and 110V of voltage.
R: Required: We need to find the current measured.
A: Action: We can use Ohm's law that relates resistance, voltage and current in the equation:
V = R*I
Or:
I = V/R
<em>Where I is current in A, V is voltage = 110V and R is resistance = 28Ω</em>
S: Solve:
I = 110V / 28Ω
I = 3.93A
S: Statement:
<h3>The current of the toaster is 3.93A</h3>
Answer:
All soil is made up of inorganic mineral particles, organic matter (including living things), air and water. Inorganic mineral particles make up more than half the volume of soil. These particles come from rocks – the parent material that formed the soil.

The osmotic pressure of a solution made from 12.5 g of CaCl2 in enough water to make 500 mL, if CaCl2 is 78.5% dissociated at 30oC is 167.087 atm
<h3>
Define osmotic pressure:-</h3>
Osmotic pressure and osmosis are connected. Osmosis is the passage of a solvent through a semipermeable membrane into a solution. The pressure that halts the osmosis process is known as osmotic pressure. Osmotic pressure is a collective attribute of material because its value is determined by the solute's concentration rather than its chemical composition.
The formula used to calculate Osmotic Pressure is:-
π = M x R x T x i
Where;
π =osmotic pressure (in atm)
M=molar concentration (in mol/L)
=(given mass/molar mass)/volume=(12.5g /111.0)/(500/1000)
=0.224 mol/L
R=Universal gas constant (0.08206 L.atm/mol.K)
T=absolute temperature (in K) = 30.C + 273 = 303 K
i= van't Hoff factor of solute =3
using the formula and substituting values;
π=0.224 x 0.08206 x 303 x 3
= 167.087 atm
The osmotic pressure is 167.087 atm
