<h2>Answer:</h2>
All the energy sources are correctly matched with their category.
Explanation:
Renewable energy sources:
These are energy sources which can be replenished as they don't in involves the irreversible phase change.
These resources can never be ended as they can be used again and again.
Wind, geothermal, biomass, bio gas are example of renewable energy sources.
Non renewable energy sources:
These are the energy source which can never be replenished after one time use. They undergo the chemical irreversible change.
These sources are lacking with the passage of time because they can never be reused.
Oil, gas, coal and natural gas are examples.

Explanation:
Answer:
3.57 m/s
Explanation:
The sum of the 2 momentums Is equal the finale momentums. so if momentums Is q, v Is velocity and m Is Mass, q3=m1*v1+m2**v2=16+9=25 m*kg/s
q3=m3*v3
v3=q3/m3=25/(4+3)=3.57m/s
Answer:
Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.
