Answer:
<h3>4.0Wb/m²</h3>
Explanation:
Magnetic flux Ф is expressed using the formula;
Ф = BA
B is magnetic field
A is the area of the square conductor
Given
B = 1.0T
A =L²
Area A = 2.0² = 4.0m²
Get the magnetic flux
Ф = 1.0 * 4.0m²
Ф = 4.0Wb/m²
Hence the magnetic flux through the conductor is 4.0Wb/m²
π=iMRT
Where, π is Osmotic pressure,
i=1 for non-electrolytes,
M is molar concentration of dissolved species (units of mol/L)
R is the ideal gas constant = 0.08206 L atm mol⁻¹K⁻¹,
T is the temperature in Kelvin(K),
Here, to calculate M convert into standard units mg tog, ml to L, c to Kelvin
M= (
*10⁻³ )/ 0.175 =(5.987 *10⁻⁵)mol / 0.175L = 34.21*10⁻⁵ mol/L
π=iMRT=(1)*(34.21*10⁻⁵)*(0.08206)*(298.15)=837×10⁻⁵= 8.37×10⁻³ atm
=6.36 torr
(1 atm=760 torr, 1 Kelvin =273.15 °C, 1L=1000ml, 1g=1000mg)
Testing the electrical resistance of different materials. it is the answer
When you rub a balloon on a sweater, for example, some electrons come off and end up on the balloon. The fibers have lost electrons giving them a positive charge. The rubber gained electrons giving it a negative charge. ... The positively charged fibers are now attracted to the negatively charged balloon.
