a measuring cylinder contains 30cm3 of a liquid some more of the liquid is added until the liquid level reaches the 50cm3 mark t

S_A_V [24]

Answer:

1.5g/cm³

Explanation:

Given parameters:

Initial volume of the liquid = 30cm³

Final volume of the liquid = 50cm³

Mass of the liquid = 30g

Unknown:

Density of the liquid = ?

Solution:

Density is the mass per unit volume of a substance.

Density = $\frac{mass}{volume}$

volume of the liquid = final volume - initial volume = 50cm³ - 30cm³

volume of the liquid = 20cm³

Density = $\frac{30}{20}$ = 1.5g/cm³

Calculate the force of gravity on the 1.2-kg mass if it were 1.9×107 m above earth's surface (that is, if it were four earth rad

Anettt [7]

Answer:

Force of gravity, F = 0.74 N

Mass of an object, m = 1.2 kg

Distance above earth's surface, $d=1.9\times 10^7\ m$

Mass of Earth, $M=5.97\times 10^{24}\ kg$

Radius of Earth, $r=6.37\times 10^6\ m$

We need to find the force of gravity above the surface of Earth. It is given by :

$F=G\dfrac{mM}{R^2}$

R = r + d

R = 25370000 m

$F=6.67\times 10^{-11}\times \dfrac{5.97\times 10^{24}\ kg\times 1.2\ kg}{(25370000\ m)^2}$

F = 0.74 N

So, the force of gravity on the object is 0.74 N. Hence, this is the required solution.
