Answer:
1875 meters
Explanation:
We are given;
- Velocity of the motorcycle as 90 km/hr
- Time as 75 seconds
We are required to calculate the displacement;
- First we will convert speed to m/s
- The suitable conversion factor will be;
1 m/s = 3.6 km/hr
Therefore, 90 km/hr
= 90 km/hr ÷ 3.6 km/hr per m/s
= 25 m/s
But;
Displacement = Velocity × time
Thus;
Displacement = 25 m/s × 75 seconds
= 1875 meters
Explanation:
observation is something what you could observe from your organs like eyes ears etc and also it is what you observed during an event for an experiment but inference is what you decide to do after observation or an event.
the act of inferring (to derive by reasoning). Observation = an act or instance of noticing or perceiving.

Deltas are complex depositional landforms that develop at the mouths of rivers. They are composed of sediment that is deposited as a river enters a standing body of water and loses forward momentum. Famous deltas include the Mississippi delta in Louisiana and the Nile delta in Egypt.
Answer:
Double the current
Explanation:
The energy delivered by the heater is related to the current by the following relation:
E= 
let R * t = k ( ∴ R and t both are constant)
so E= k 
Now let:
E2= k I₂^2
E2= 4E
⇒ k I₂^2= 4* k
Cancel same terms on both sides.
I₂^2= 4*
taking square-root on both sides.
√I₂^2 = √4* I^2
⇒I₂= 2I
If we double the current the energy delivered each minute be 4E.
