A. Made of the marble.
the mass remains constant when you drop the marble but the rest of the variables change as the marble is dropped, therefore, the only constant variable is its mass.
Answer:
The tangential speed at Livermore is approximately 284.001 meters per second.
Explanation:
Let suppose that the Earth rotates at constant speed, the tangential speed (
), measured in meters per second, at Livermore (37.6819º N, 121º W) is determined by the following expression:
(1)
Where:
- Rotation time, measured in seconds.
- Radius of the Earth, measured in meters.
- Latitude of the city above the Equator, measured in sexagesimal degrees.
If we know that
,
and
, then the tangential speed at Livermore is:
![v = \left(\frac{2\pi}{86160\,s} \right)\cdot (6.371\times 10^{6}\,m)\cdot \sin 37.6819^{\circ}](https://tex.z-dn.net/?f=v%20%3D%20%5Cleft%28%5Cfrac%7B2%5Cpi%7D%7B86160%5C%2Cs%7D%20%5Cright%29%5Ccdot%20%286.371%5Ctimes%2010%5E%7B6%7D%5C%2Cm%29%5Ccdot%20%5Csin%2037.6819%5E%7B%5Ccirc%7D)
![v\approx 284.001\,\frac{m}{s}](https://tex.z-dn.net/?f=v%5Capprox%20284.001%5C%2C%5Cfrac%7Bm%7D%7Bs%7D)
The tangential speed at Livermore is approximately 284.001 meters per second.
Answer:
answer is D.it will decrease
Answer:
2500 Newtons
Explanation:
If force equals the mass × acceleration then all should be quite simple
25kg is the mass of your car
100 m/s/s is the acceleration of you car
25kg • 100m/s/s = 2500 Newtons
