How much heat is absorbed by a 29g iron skillet when its temperature rises from 9oC to 105oC?

We have:

Mass (m) of the iron skillet = 29 grams
Difference in temperature (Δt) = 105 - 9 = 96°C
Heat capacity of iron = 0.449 J/g °C

The energy (Q) is given by:

Q = m × Δt × specific heat
Q = 29 grams × 96 °C × 0.449 J/g°C
Q = 1250.016 Joules

A mountain-climber friend with a mass of 74 kg ponders the idea of attaching a helium-filled balloon to himself to effectively r

bazaltina [42]

Answer:

$V=16.65 m^3$

Explanation:

The volume of the balloon can be find compared the force in each cases so:

reduce 25% from 74kg

$R=\frac{25}{100}*74kg=18.5kg$

So the net force uproad on the balloon is

$F_b=18.5kg*g$

Now the density of the both gases air and helium are different however the volume is the same change offcorss the mass so:

$P_h=\frac{m}{V}=0.179 kg/m^3$

$P_A=1.29 kg/m^3$

$F_b=F_A-F_H$

$F_b=m_a*g-m_h*g$

$m=P/V$

$18.5kg*g=(1.29kg/m^3-0.179kg/m^3*)V*g$

$V=\frac{18.5kg}{(1.29-0.179)kg/m^3}$

$V=16.65 m^3$

Density of iron in CGS unit is 7.8 g/cm3. Its density is SI is

kumpel [21]

Answer:

7800kg/m³

Explanation:

Density of iron in CGS unit is 7.8 g/cm3. Its density is SI is

Given the density of iron = 7.8 g/cm3.

The SI units must be in kg/m³

7.8g = 7.8/1000 kg

7.8g = 0.0078kg

1cm³ = 0.000001m³

7.8g/cm³

= 0.0078/0.000001 kg/m³

= 7800kg/m³

Hence the density in SI unit is 7800kg/m³

how will resistance change when the voltage increases in an electric circuit if the current remains constant

Yakvenalex [24]

V=IR
Potential Difference (v)= Current (A) * Resistance (Ω)
As V increases, R also increases.
