A because the ball is moving up (kinetic) and the higher it goes the greater the potential energy when it'll fall.

An astronaut goes out for a space-walk at a distance above the earth equal to the radius of the earth. What is her acceleration

Lera25 [3.4K]

Answer: $\frac{g}{4}$

Explanation:

Let m be the mass of Astronaut

M=mass of earth

G=Gravitational constant

R=radius of Earth

Force Exerted by Earth on Astronaut

$F=\frac{GmM}{R^2}$

acceleration due to gravity is $=\frac{F}{m}=g$

$g=\frac{GM}{R^2}$

When it is at $r=2R$

$g'=\frac{GM}{(2R)^2}$

$g'=\frac{GM}{4R^2}=\frac{g}{4}$

A reaction taking place in a container with a piston-cylinder assembly absorbs 4850. J of heat and has a change in the internal

Maslowich

Answer:

$V_f = 16.3 Ltr$

Explanation:

As per first law of thermodynamics we know that

heat absorbed = change in internal energy + Work done

so we have

$Heat = 4850 J$

$\Delta U = 1618.5 J$

so work done is given as

$4850 = 1618.5 + W$

$W = 3231.5 J$

now we know that at constant pressure the work done is given as

$W = P\Delta V$

$3231.5 = P(V_f - V_i)$

$3231.5 = 5.5 \times 1.01 \times 10^5(V_f - 10.5 \times 10^{-3})$

$V_f = 16.3 \times 10^{-3} m^3$

or we have

$V_f = 16.3 Ltr$
