Answer:
speed
Explanation:
Given: an incomplete sentence
To fill: the blank
Solution:
Speed is not a vector quantity but a scalar quantity as it has magnitude but no direction.
Speed = Distance ÷ Time
You can calculate an <u>average</u> speed if you know both the total distance and the total time of the trip.
Average speed = Total distance ÷ Total time
Answer:
Potential
Explanation:
The most accurate term is Electrostatic potential energy
It's named like this because the force between charges or electrons is called electrostatic force .
Every object in the universe attracts every other object with a force which is proportional to the product of their masses and inversely proportional to the square of the distance between them. The forces along the line joining the centre of the two objects.
❍ Let us consider two masses m1 and m2 line at a separation distance d. Let the force of attraction between the two objects be F.
According to universal law of gravitation,
Also,
Combining both, We will get
Or, We can write it as,
Where, G is the constant of proportionality and it is called 'Universal Gravitational constant'.
☯️ Hence, derived !!

Answer
given,
Distance for decibel reading
r₁ = 13 m
r₂ = 24 m
When the engineer is at r₁ reading is β₁ = 101 dB
now, Calculating the Intensity at r₁
Using formula
I₀ = 10⁻¹² W/m²
now inserting the given values
I = 0.01258 W/m²
now, calculating power at r₁
P₁ = I₁ A₁
P₁ = 0.01258 x 4 π r²
P₁ = 0.01258 x 4 π x 13²
P₁ = 26.72 W
according to PBS learning media on a roller coaster energy changes from potential to kinetic energy and back again many times over the course of a ride kinetic energy is energy that an object has as a result of its motion.
roller coaster system is greatest at the bottom of the largest downhill slope on the track typically at the bottom of the lift Hill
so at the bottom
