Neon-22 is the isotope with the greater mass.

P.S. When you have two isotopes of the same element, the one with the greater number will always have the greater mass

Hope that helps!

The escape velocity from Earth's surface is 1.12 x 104 meters per second. At this speed, how many kilometers would a

Sati [7]

Answer:

2016 km

Explanation:

The escape velocity from Earth's surface is $1.12\times 10^4\ m/s$ .

We need to find how many kilometers would a rocket travel in three minutes. It is a concept based on the definition of speed of an object.

Speed = distance per unit time

1 hour = 60 minutes

⇒ 3 minutes = 0.05 hour

1 m/s = 3.6 km/h

11200 m/s = 40320 km/h

So,

$\text{distance}, d=v\times t\\\\d=40320\ km/h \times 0.05\ h\\\\d=2016\ km$

Hence, a rocket will travel 2016 km in 3 minutes.
