yes
Explanation:
you will feel weary after shorter times
Answer:
m g sin theta = force of object along incline due to gravity
N μ = frictional of incline on object where N is the normal force
N = m g cos theta force perpendicular to incline
m g sin theta = N μ = μ m g cos theta
μ = tan theta = tan 38 = .78
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:
250 mL
Explanation:
If the density is more than that of water (in this case it is) it will sink to the bottom of the container holding water (if it fits).
That being the case, the amount of water displaced = the volume of the castle.
Answer: 250 mL
