The right formula to use for this calculation is the heat capacity formula, 
Heat absorbed, Q = MCT, Where 
M = Mass of the substance = 71
C = Specific heat capacity for iron = 0.450 J/gc
T = Change in temperature = 29 - 11 = 18
Q = 71 * 0.450 *18 = 575.10
The amount of heat absorbed by the iron skillet is 575 J.

Steve tunes an old-fashioned radio that has an antenna made from a 3.0-cm-long solenoid with a cross-sectional area of 0.50 cm2
sukhopar [10]

Answer:

L = 1.88\times10^-^4 H

Explanation:

It is given that,

Length of the coil, l = 3 cm = 0.03 m

Area of cross section of the coil, A=0.5\ cm^2=0.00005\ m^2

Number of turns in the coil, N = 300

inductance of the coil is

L=\dfrac{\mu_oN^2A}{l}

L=\dfrac{4\pi\times 10^{-7}\times (300)^2\times 5\times 10^{-5}}{0.03}\\L = 1.88\times10^-^4 H

So, the inductance of the coil is 1.88× 10⁻⁴H

Josh is much bigger than taylor. after the push, which of the two is moving faster?
egoroff_w [7]
If E = 1/2 * m * v^2
v = (2E/m)^1/2
so the larger the mass, the higher the velocity hence taylor is moving faster

The parking brake on a 1000 kg Cadillac has failed, and it is rolling slowly, at 1 mph , toward a group of small children. Seein
GalinKa [24]
Um of momenta = 0( Since both the cars stop) 
<span>Let m1 be the mass of the cadillac and m2 be the mass of the volkswagen. </span>
<span>then, v1=speed of cadillac and v2=speed of volkswagen. </span>
<span>Therefore, (m1)*(v1) + (m2)*(v2) = 0 </span>
<span>Substituting, </span>
<span>(1000*4) + (2000*v2) = 0 </span>
<span>4000 = - 2000 v2 </span>
<span>Therefore, v2= - 2 m/s. </span>
