The amount of heat per second conducted from the blood capillaries beneath the skin to the surface is 250 j/s. the energy is tra

marin [14]

Heat flux (i) = k.a.temp variation/d
i = 250 J/s or 250w ; d = 2.1 x 10^-3m ; A = 1.9m^2 ; K (Body Fat) = 0.2W/m.Kelvin ; Temp. Var. (Delta T) = ?

-> 250 = 0.2 x 1.9 x deltaT/2.1 x 10^-3
-> 250 x 2.1 x 10^-3 = 0.38 x deltaT
-> 525 x 10^-3 = 38x10^-2 x deltaT
-> deltaT = 525 x 10^-3/ 38 x 10^-2
-> deltaT = 13.81 x 10^(-3 - (-2))
-> deltaT = 13.81 x 10^-1
-> deltaT = 1.381 K

A 0.10- kg ball is thrown straight up into the air with

mezya [45]

Answer:(a)0,(b)1.061 kg-m/s

Explanation:

Given

mass of ball is 0.10 kg

Initial speed is 15 m/s

Maximum height reached by ball is h

$v^2-u^2=2as$

final velocity =0

$-\left ( 15\right )^2=-2\times 9.81\times s$

$s=\frac{15^2}{2\times 9.81}=11.467 m$

thus momentum of ball at maximum height is 0 as velocity is zero

For halfway to maximum height

$v^2-u^2=2as_0$

where $s_0=\frac{11.467}{2}$

$s_0=5.73 m$

$v^2=15^2-2\times 9.81\times 5.73$

v=10.61 m/s

Thus its momentum is

$mv=0.10\times 10.61=1.061 kg-m/s$
