Answer:

77.3W (to 3sf)

Explanation:

weight = mass × gravtaional field strength

           = 6.35kg × 10N/kg

           = 63.5N

weight = force = 63.5N

work done = force × distance

                  = 63.5N × 5.11m

                  = 324.485J

power = \frac{work done}{elapsed time}

           = \frac{324.485J}{4.2s}

           = 77.3W (to 3sf)

Un cuerpo de 60 kg se encuentra a una distancia de 3.5 m del otro cuerpo, de manera que entre ellos se produce una fuerza de 6.5
aev [14]

Answer:

1989.6Kg

Explanation:

The computation of the mass of the other body is given below:

As we know that

F = G × m1 × m2 ÷ r²

Here the G would have the constant value i.e. 6.67 × 10^-11Nm² / kg².  

Now

6.5 × 10^-7N = 6.67 × 10^-11Nm² / kg² × 60Kg × m2 / (3.5m) ²

m2 = (F × r²) / (G × m1)

m2 = (6.5 × 10^-7N × (3.5m) ²) ÷ (6.67 × 10^-11Nm² / kg² × 60Kg)

= 1989.6Kg

How much energy (in joules) is required to evaporate 0.0005 kg of liquid ammonia to vapor at the same temperature?
Lana71 [14]

Answer:

685.6 J

Explanation:

The latent heat of vaporization of ammonia is

L = 1371.2 kJ/kg

mass of ammonia, m = 0.0005 Kg

Heat = mass x latent heat of vaporization

H = 0.0005 x 1371.2

H = 0.686 kJ

H = 685.6 J

Thus, the amount of heat required to vaporize the ammonia is 685.6 J.
