The escape speed from an object is v2 = 2GM/R, where M is the mass of the object, R is the object's starting radius, and G is th

Rom4ik [11]

Answer:

Approximate escape speed = 45.3 km/s

Explanation:

Escape speed

$v=\sqrt{\frac{2GM}{R}}$

Here we have

Gravitational constant = G = 6.67 × 10⁻¹¹ m³ kg⁻¹ s⁻²

R = 1 AU = 1.496 × 10¹¹ m

M = 2.3 × 10³⁰ kg

Substituting

$v=\sqrt{\frac{2\times 6.67\times 10^{-11}\times 2.3\times 10^{30}}{1.496\times 10^{11}}}=4.53\times 10^4m/s=45.3km/s$

Approximate escape speed = 45.3 km/s

A cube of copper was found to have a mass of 630 g. What are the dimensions of the cube? (The density of copper is 8.94 g/cm3.)

raketka [301]

Answer:

Density = mass/volume

Volume of cube = mass/density

630g/8.94 = 70.5cm^3 (3s.f.)

Since it is a cube, its dimensions of Length x breadth x height=volume

Take 70.5 amd cube root it

$\sqrt[3]{70.4697986577)$

=4.13 (3s.f)

hence , it would be 4.13 x 4.13 x 4.13 to find the volume

Hence, the answer would be 4.13cm(3s.f.)
