Suppose that 2.5 moles of an ideal gas are in a chamber in equilibrium at temperature 310 K and volume 0.5 m3. 1) What is the pr

Basile [38]

Answer:

The pressure in the chamber are of p= 0.127 atm.

Explanation:

n= 2.5 moles

T= 310 K

V= 0.5 m³ = 500 L

R= 0.08205746 atm. L /mol . K

p= n*R*T/V

p= 0.127 atm

A flat loop of wire consisting of a single turn of cross-sectional area 7.10 cm2 is perpendicular to a magnetic field that incre

Lina20 [59]

Answer:

The induced current is $I = 0.00066 \ A$

Explanation:

From the question we are told that

The area is $A = 7.10 \ cm^2 = 7.10 *10^{-4} \ m^2$

The initial magnetic field is $B_i = 0.500 \ T$

The magnetic field after t =1.07 s is $B_f = 2.10 \ T$

The resistance of the loop is $R = 1.60 \ \Omega$

Generally the electromagnetic field induced is mathematically represented as

$\epsilon = NA * \frac{B_f - B_i}{t}$

Where N is the number of turns which is 1 in the case of this question since there is only one loop

$\epsilon = 1 * 7.10*10^{-4}* \frac{2.10 - 0.500}{1.07 }$

=> $\epsilon = 0.00106 \ V$

Generally the value of the current is mathematically represented as

$I = \frac{\epsilon}{R}$

$I = \frac{0.00106}{1.60}$

$I = 0.00066 \ A$

A burning candle is covered by a jar as shown in the picture. The whole arrangement has a mass of 500 g. What will be the approx

Anna11 [10]

The law of conservation of matter is that the amount of matter you begin the reaction with is the amount you will end up with. So if you start with 500g of matter, when you burn the candle you will also have 500g of matter to end with. SO D is your answer
