Nataly [62]

Explanation:

distance covered in the first part of journey : 120×14 = 1680km

distance covered in second part of journey :

90×10 = 900 km

total distance traveled : 1680+900 = 2580km.

total time taken to complete the journey : 14+10= 24 hrs.

therefore, the average speed of the journey = 2580km/24hr = 107.5 km/h.

hope this helps you.

Two astronomical objects with mass of 3.1 x 10^20 kg and 7.4 x 10^18 kg are separated by a distance of 6.5 x 10^6 m. What is the
bekas [8.4K]

Answer:

3.62 x 10^15 N

Explanation: We will solve this problem by using Newton's Law of Universal Gravitation.

F =  <u>G m1*m2/</u> r^2     where

F= Force of attaction between each object

m1 and m2 the masses of the objects

r squared the distance between the objects

G= Gravitational constant

Working in the S.I the answar becomes:

F= 6.67x10^-11 * 3.1x10^20*7.4x10^18/(6.65x10^6)^2

F= 3.62 x 10^15  N
