A coil has N turns enclosing an area of A. In a physics laboratory experiment, the coil is rotated during the time interval Δt f
scoray [572]

Answer:

BA

0

\dfrac{NBA}{\Delta t}

Explanation:

B = Magnetic field

A = Area

\theta = Angle

t = Time taken

Before rotation the magnetic flux is given by

\phi_i=BAsin\theta\\\Rightarrow \phi_i=BAsin90\\\Rightarrow \phi_i=BA

Magnetic flux is BA

After rotation the magnetic flux is given by

\phi_i=BAsin\theta\\\Rightarrow \phi_i=BAsin0\\\Rightarrow \phi_i=0

The magnetic flux is 0

Magnitude of emf is given by

\epsilon=NA\dfrac{d\phi}{dt}\\\Rightarrow \epsilon=\dfrac{NBA}{\Delta t}

The magnitude of the average emf induced in the entire coil is \dfrac{NBA}{\Delta t}

A small metal sphere weighs 0.34 N in air and has a volume of 13 cm3 . What is the acceleration of the sphere as it falls throug
Xelga [282]

To solve this problem we will apply the concepts related to the balance of forces. Said balance will be given between buoyancy force and weight, both described as derived from Newton's second law, are given as

Buoyancy force

F_B = V\rho g

Here,

V = Volume

\rho=Density of air

g = Acceleration due to gravity

Weight

F_W = mg

m = mass

g = Gravity

Our values are given as,

\text{Weight of the sphere} = W = 0.34 N

\text{Volume} = V = 13 cm^3 = 13*10^{-6}m^3

\text{density of air} =\rho =1.29kg/m^3

\text{gravity}= g = 9.8 m/s^2

Then,

F = V\rho g

Replacing,

F = (13*10^{-6}m^3 )(1.29Kg/m^3)( 9.8 m/s^2) = 1.6434* 10^{-4} N

Now net force is ,

F_{net} = mg - F

Mass of the sphere is

m = \frac{W}{g} = \frac{0.34N}{9.8m/s^2} = 0.03469 kg

Now acceleration of the sphere is

a = \frac{F_{net}}{m}

a = \frac{( 0.34 N)- (1.6434* 10^{-4} N)}{0.03469 kg}

a = 9.822m/s^2

Therefore the acceleration of the sphere as it falls through water is 9.822m/s^2

A first-order reaction has a rate constant of 0.241/min. if the initial concentration of a is 0.859 m, what is the concentration
nordsb [41]

Answer: 0.077 M

Explanation:

Expression for rate law for first order kinetics is given by:

k=\frac{2.303}{t}\log\frac{a}{a-x}

where,

k = rate constant = 0.241minute^{-1}

t = time taken for decay process = 10 minutes

a = initial amount of the reactant= 0.859 M

a - x = amount left after decay process =?

Putting values in above equation, we get:

0.241 minutes^{-1}=\frac{2.303}{10.0}\log\frac{0.859}{a-x}

(a-x)=0.077M

Thus the concentration of a after 10.0 minutes is 0.077 M.
