A scientist measuring the resistivity of a new metal alloy left her ammeter in another lab, but she does have a magnetic field p

nalin [4]

Answer:

$3.49\times 10^{-8}\ \Omega\text{m}$

Explanation:

r = Radius = $\dfrac{2}{2}=1\ \text{mm}$

B = Magnetic field = 3 mT

1 mm = Distance from the surface of the wire

V = Voltage

x = Distance from the probe = $r+1=1+1=2\ \text{mm}$

R = Resistance

L = Length of wire = 4.5 m

Magnetic field is given by

$B=\dfrac{\mu_0I}{2\pi x}\\\Rightarrow I=\dfrac{B2\pi x}{\mu_0}\\\Rightarrow I=\dfrac{3\times 10^{-3}\times 2\times \pi 2\times 10^{-3}}{4\pi 10^{-7}}\\\Rightarrow I=30\ \text{A}$

Voltage is given by

$V=IR\\\Rightarrow R=\dfrac{V}{I}\\\Rightarrow R=\dfrac{1.5}{30}\\\Rightarrow R=0.05\ \Omega$

Resistivity is given by

$\rho=\dfrac{RA}{L}\\\Rightarrow \rho=\dfrac{0.05\times \pi (1\times 10^{-3})^2}{4.5}\\\Rightarrow \rho=3.49\times 10^{-8}\ \Omega\text{m}$

The resistivity of the material is $3.49\times 10^{-8}\ \Omega\text{m}$ .

A mass of (200 g) of hot water at (75.0°C) is mixed with cold water of mass M at (5.0°C). The final temperature of the mixture i

MArishka [77]

Answer:

500 g

Explanation:

Specific heat of water = 1 j/g-c

Heat given up by hot water = 200(75-25)(1) = 10 000 j

this is the heat GAINED by the cold water

10000 j = x ( 25 -5)(1)

x =500g
