In this case, the movement is uniformly delayed (the final
rapidity is less than the initial rapidity), therefore, the value of the
acceleration will be negative.
1. The following equation is used:
a = (Vf-Vo)/ t
a: acceleration (m/s2)
Vf: final rapidity (m/s)
Vo: initial rapidity (m/s)
t: time (s)
2. Substituting the values in the equation:
a = (5 m/s- 27 m/s)/6.87 s
3. The car's acceleration is:
a= -3.20 m/ s<span>^2</span>
Answer:
c. 981 watts

Explanation:
Given:
- horizontal speed of treadmill,

- weight carried,

- grade of the treadmill,

<u>Now the power can be given by:</u>

(where grade is the rise of the front edge per 100 m of the horizontal length)

It will land in your lap because there's different frames of motion relative to yourself. For example, if you're running at a speed of 6 mph, it doesn't mean you'll run as fast as the Earth spins. Also, since you're on the interior of the plane, any kind of wind or weather on the outside will not affect the coin. A law to back up this claim is Einsteins Special Law of Relativity.
B. Tornado destruction
It is based on the amount of damage
Answer:
waves that are created as a result of vibrations between an electric field and a magnetic field
