What is the density of a block of marble that

EleoNora [17]

Explanation:

Solution,

Volume (v)=287 cm^3

Mass(m)=816 g

Density(d)=m/v

=816/287

=2.84

So, the density of the block of marbles is 2.84 g/cm^3.

Answer:

<h2>Rate of heat transfer from the body of the person is given as</h2><h2> $\frac{dQ}{dt} = 800 J/s$ </h2>

Explanation:

As we know that the rate of heat transfer due to thermal conduction is given as

$\frac{dQ}{dt} = \frac{kA(T_2 - T_1)}{x}$

so we have

k = 0.04 W/m C

$A = 1.6 m^2$

$x = 2\times 10^{-3} m$

$\frac{dQ}{dt} = \frac{(0.04)(1.6)(36 - 11)}{2 \times 10^{-3}}$

$\frac{dQ}{dt} = 800 J/s$
