A wedge is a simple machine that is used to cut or split an object.
Hope I helped!
Use f = uN to find the coefficient of friction. We know friction (6.0 N) and the normal forces (18 N), so plug them in to the equation which gives us 6 = u18. Solving for u: <span>u = 0.33</span>
Answer:
24.79 m/s2
Explanation:
Let us assume that there is an object with a mass of 'm' on the
Jupiter. Jupiter will attract this object:
![mg_j=G\frac{mM_j}{r_j^{2} }](https://tex.z-dn.net/?f=mg_j%3DG%5Cfrac%7BmM_j%7D%7Br_j%5E%7B2%7D%20%7D)
![g_j=G\frac{M_j}{r_j^{2} }](https://tex.z-dn.net/?f=g_j%3DG%5Cfrac%7BM_j%7D%7Br_j%5E%7B2%7D%20%7D)
![g_j=6.67*10^{-11} \frac{1.9*10^{27} }{71492000^{2} }](https://tex.z-dn.net/?f=g_j%3D6.67%2A10%5E%7B-11%7D%20%5Cfrac%7B1.9%2A10%5E%7B27%7D%20%7D%7B71492000%5E%7B2%7D%20%7D)
![g_j=24.79m/s^{2}](https://tex.z-dn.net/?f=g_j%3D24.79m%2Fs%5E%7B2%7D)
Answer:
The average velocity that these birds travel is 122.22 miles per day to the south.
Explanation:
Speed is the physical quantity that expresses the variation in position of an object and as a function of time. In other words, speed is a physical quantity that expresses the relationship between the space traveled by an object, the time used for it and its direction.
Speed is expressed mathematically as the quotient between distance and time:
![v=\frac{d}{t}](https://tex.z-dn.net/?f=v%3D%5Cfrac%7Bd%7D%7Bt%7D)
where "v" is the speed of the mobile, "d" is the distance traveled by the mobile, and "t" is the time taken by the mobile to carry out the movement.
In this case:
- d= 11,000 miles
- t=3 months= 90 days (
considering that in 1 month there are 30 days)
Replacing:
![velocity=\frac{11,000 miles}{90 days}](https://tex.z-dn.net/?f=velocity%3D%5Cfrac%7B11%2C000%20miles%7D%7B90%20days%7D)
velocity = 122.22 ![\frac{miles}{day}](https://tex.z-dn.net/?f=%5Cfrac%7Bmiles%7D%7Bday%7D)
<u><em>The average velocity that these birds travel is 122.22 miles per day to the south.</em></u>
