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.

Converting the following mm Hg (torr) to standard
11Alexandr11 [23.1K]

Explanation:

Given:

20.5 torr

78.6 torr

225 torr

Change into atm

Computation:

We know that;

1 torr = 0.00131579 atm

So,

1. 20.5 torr

= 20.5 x 0.00131579 atm

= 0.02697

= 0.027 atm (Approx)

2. 78.6 torr

= 78.6 x 0.00131579 atm

= 0.103090

= 0.103 atm (Approx)

3. 225 torr

= 225 x 0.00131579 atm

= 0.2960

= 0.296 atm (Approx)
