Q = Charge delivered by the wire = 12.0 C

t = time taken for the charge to be delivered = 4.0 s

i = current flowing in the wire due to the flow of charge  = ?

Current is defined as the time rate at which charge pass through a particular point.

Current in the wire is given as

i = Q/ t

inserting the values

i = (12.0) /(4.0)

i = 3 A

hence the correct choice is 3.0 A

Baseball reporters say that long fly balls that would have carried for home runs in July "die" in the cool air of Octo- ber and
anastassius [24]

Answer:

Consider the followig calculation

Explanation:

a)  use deal equation:

PV = nRT                      

ρ = m/V,= ==> V = m/ρ

therefore,

ρ = Pm/RT

convert 95 oF in degree

95 oF = 308.15 K

1 atm = 1.013 * 105 pascal

ρ = 1.013*105 * 29 * /8.314 * 308.15

                   = 1.146 kg/m3

b)  again use ideal gas equation:

ρ = Pm/RT

T = 50 oF = 283.15 K

1 atm = 1.013 * 105 pascal

molar mass will be same

ρ = 1.013 * 105 * 29 / 8.314 * 283.15

ρ = 1.248 kg / m3

So,

c) . more than density of the hot, dry air computed in part (a)

A ten loop coil of area 0.23 m2 is in a 0.047 T uniform magnetic field oriented so that the maximum flux goes through the coil.
Nana76 [90]

Answer:

0.32 V

Explanation:

N = 10, A = 0.23 m^2, B = 0.47 T, t = 0.34 s

The average induced emf is given by

e = - N dФ / dt

Where, dФ be the change in magnetic flux in time dt.

dФ / dt = d / dt (B A) = A dB/dt

So,

e = - 10 x 0.23 x 0.047 / 0.34 = - 0.32 V

The negative sign shows the direction of induced emf.

A person, whose eye has a lens-to-retina distance of 2.0 cm, can only clearly see objects that are closer than 1.0 m away. what
shutvik [7]

To calculate the strength of the eye lens, we use the formula

\frac{P}{100} = \frac{1}{f} =\frac{1}{u} +\frac{1}{v}  ( thin lens formula)

Here, u is the object distance and v is image distance.

Given, u =1 m=100cm and v = 2 cm

Therefore,

\frac{1}{f} =\frac{1}{100} + \frac{1}{2}

\frac{1}{f} = 0.01 + 0.5= 0.51 cm

Thus, strength of the eye lens is

P= \frac{100}{f} =\frac{100}{\frac{1}{0.51} } = 51 D
