Answer:
29865.31 m/s
Explanation:
Radius of the Earth orbit if it is assumed to be circular = 1.5×10¹¹ m = r
<em>Circumference of the orbit = 2πr</em>
<em>= 2π×1.5×10¹¹</em>
<em>= 3π×10¹¹ m</em>
Time taken by Earth to complete one rotation around the orbit = 365.25 days
<em>Converting to seconds we get</em>
<em>365.25×24×60×60</em>
<em>= 31557600 seconds</em>
Velocity of Earth
∴ The average speed of Earth in its orbit is 29865.31 m/s
Answer:
25km/h
Explanation:
This is a trick question, the average speed in this case does not really depend on calculation or extrapolation, it just refers to an event that is yet to occur,
In other words, if you want to achieve an average speed of 25km/h for 23km, then you should drive your car at a constant speed of 25km/h, any variation in speed may cause a change in your average speed at the end.
That makes no sense I can't help sorry
Answer:
<h3>The answer is option A</h3>
Explanation:
To find the mass of an object given it's acceleration and the force acting on it we use the formula
From the question
force = 500 N
acceleration = 5.0 m/s²
We have
We have the final answer as
<h3>100 kg</h3>
