Answer:
the theoretical maximum energy in kWh that can be recovered during this interval is 0.136 kWh
Explanation:
Given that;
weight of vehicle = 4000 lbs
we know that 1 kg = 2.20462
so
m = 4000 / 2.20462 = 1814.37 kg
Initial velocity
= 60 mph = 26.8224 m/s
Final velocity
= 30 mph = 13.4112 m/s
now we determine change in kinetic energy
Δk =
m(
² -
² )
we substitute
Δk =
×1814.37( (26.8224)² - (13.4112)² )
Δk =
× 1814.37 × 539.5808
Δk = 489500 Joules
we know that; 1 kilowatt hour = 3.6 × 10⁶ Joule
so
Δk = 489500 / 3.6 × 10⁶
Δk = 0.13597 ≈ 0.136 kWh
Therefore, the theoretical maximum energy in kWh that can be recovered during this interval is 0.136 kWh
Answer:
It is d. 0.80
Trust me i got it right took it and got it right
Answer:
258774.9441 m
Explanation:
x = Distance of probe from Earth
y = Distance of probe from Sun
Distance between Earth and Sun = 
G = Gravitational constant
= Mass of Sun = 
= Mass of Earth = 
According to the question


The probe should be 258774.9441 m from Earth
Answer:
A. They diverge on refraction
Explanation:
- The concave lens has the physical characteristics that both sides are curved inwardly. Due to this physical nature, the lens is thicker towards the outer circumference.
- Due to such physical characteristics of a concave lens, when parallel light rays strike on a concave lens, it is refracted and diverge out from the other side.
- When the diverging rays are traced back, it seems as if the rays are appearing from a point.
- This point is where the rays seem to appear is called the principal focus of the lens.
- Thus the image formed by the concave lens is erect, virtual and diminished.
Answer:
<h2>11.91 m/s</h2>
Explanation:
The velocity of an object can be found by using the formula

d is the distance
t is the time taken
From the question we have

We have the final answer as
<h3>11.91 m/s</h3>
Hope this helps you
