Answer:
F. The length of day would be longer
Explanation:
- Earths rotates on its axis from the eastward to the westward direction, earth takes about 24 hours to complete its rotation. If the rate of earth's rotation on its axis slows down then the days will be longer than usual.
- Thought the length of year would remain the same. Earth rotation is also impacted by the sun and moon's gravitational pull. The disappearance of the centrifugal force form the surface would cause climate changes and seasonal extremes.
A lower, easier gear, with the smaller chain ring up front and a largercog in the back, lets you accelerate faster.
Answer:
2.7 Pizzas.
Explanation:
The power required to walk through 5km in 1 hour is 380W.
A watt is basically Jules per second, then we need to standardized this measurement to second.
5km/hr is equal to,
Walking by 2.5 hours is equal to a distance of,
The total energy required then would be,
Then we know that one pizza slice gives of energy, the total pizza needed are,
<em>Then you need to buy 3 pizza.</em>
Answer:
a) the acceleration of the particle is ( v² - v² ) / 2as
b) the integral W = m( ² - v² )
Explanation:
Given the data in the question;
force on particle F = ma
displacement s = x - x
work done on the particle W = Fs = mas
we know that; change in energy = work done { work energy theorem }
m( v² - v² ) = mas
( v² - v² ) = as
( v² - v² ) = 2as
a = ( v² - v² ) / 2as
Therefore, the acceleration of the particle is ( v² - v² ) / 2as
b) Evaluate the integral W =
W = m( ² - v² )
Therefore, the integral W = m( ² - v² )
