An airplane travels 3100km at a speed of 790km/h, and then encounters a tailwind that boosts its speed to 990km/h for the next 2800 km. what was the total time for the trip? what was the average speed of the plane for this trip?

6.75233 h

Explanation:

✓airplane travels 3100km at a speed of 790km/h,

Speed= distance/ time

Time= speed/distance

Distance=3100 km

Speed=790km/h

Time= 3100 /790

= 3.924 h

✓and then encounters a tailwind that boosts its speed to 990km/h for the next 2800 km

Time= 2800 k990km/h

= 2800/990

= 2.828 h

We can calculate total times as (3.924 + 2.828)

= 6.75233 h

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
