Explanation:
first described the Earth as a giant dipole magnet 400 years ago. But, as Rod Wilson recounts, he did far more than this.
Answer:
less than 27 m/s
Explanation:
The average speed would be total distance (10 + 10 = 20 miles = 32000 m) over total time
The time it takes you to drive the first 10 miles (16000 m) at 24m/s is
16000 / 24 = 666.67 s
The time it takes you to drive the 2nd 10 miles (16000 m) at 30 m/s is
16000 / 30 = 533.33 s
The average speed is
< 27 m/s
So your average speed is less than 27 m/s
Answer:
–77867 m/s/s.
Explanation:
From the question given above, the following data were obtained:
Initial velocity (u) = 34.5 m/s
Final velocity (v) = –23.9 m/s
Time (t) = 0.00075 s
Acceleration (a) =?
Acceleration is simply defined as the rate of change of velocity with time. Mathematically, it is expressed as:
Acceleration = (final velocity – Initial velocity) /time
a = (v – u) / t
With the above formula, we can obtain acceleration of the ball as follow:
Initial velocity (u) = 34.5 m/s
Final velocity (v) = –23.9 m/s
Time (t) = 0.00075 s
Acceleration (a) =?
a = (v – u) / t
a = (–23.9 – 34.5) / 0.00075
a = –58.4 / 0.00075
a = –77867 m/s/s
Thus, the acceleration of the ball is –77867 m/s/s.
The weight of anything is determined on how much gravity is pulling on the object. For example a balloon full of helium floats away but iron or concrete would fall to the ground. hope this helps :)
The displacement would be the final position (37) minus the initial position (50) if using the displacement formula.
