Bella’s average velocity is about 0.693 meters per second.
To find the average velocity, you must divide the distance by the change in time, which should look like v=d/t
Here is how you set up the equation-
v=6.1/8.8
Once you divide 6.1 meters by 8.8 seconds, you should get a number that looks like 0.69318182.... however, I just rounded it to 0.693 meters per second. You can round it to whatever you like.
Hope this helped! If you have any questions about what I mentioned in my answer or explanation, feel free to comment on my answer and I’ll try to get back to you!
Magnetic field can be generated when electric charge is in motion.
In short, Your Answer would be Option C
Hope this helps!
Answer:
Tension on each chain: 30.28N
Explanation:
We start by drawing a free-body diagram of all the forces acting on the flower pot. These are:
1) the weight of the flower pot which is the product of the pot's mass time the acceleration of gravity "g" (pictured in green and represented by
in the diagram), and
2) the two tensions in the chains, which since they are symmetric, are of the same size, pictured in red color and represented by the letter "T" in the diagram.
We also decompose the tensions T in two components each (a vertical component V and a horizontal component h) which are pictured in blue.
All vertical forces must cancel out since the object is in static equilibrium, so:
![V+V=F_g\\2V=5.6*9.8 N=54.88N\\V=27.44N](https://tex.z-dn.net/?f=V%2BV%3DF_g%5C%5C2V%3D5.6%2A9.8%20N%3D54.88N%5C%5CV%3D27.44N)
The horizontal components h are equal, and since they act in opposite directions, they indeed cancel out.
Now to calculate the tension, we use the fact that we know the angle between T and the component V. They in fact are related via the cosine of the angle because they are the hypotenuse and the adjacent side in a right angle triangle:
Answer:
D
Explanation:
Think about like charges meaning the charge is the same.
Which only D has two charges and are the same, positive will repel against positive charge so select D.
Answer:
a) 42.9 m/s
b) 41.6m
Explanation:
a) ![V_{0x}=V_{0y}=\frac{v}{\sqrt{2} }](https://tex.z-dn.net/?f=V_%7B0x%7D%3DV_%7B0y%7D%3D%5Cfrac%7Bv%7D%7B%5Csqrt%7B2%7D%20%7D)
![y(t)=0.3+\frac{v}{\sqrt{2} }t -4.9t^{2} \\188=\frac{vt}{\sqrt{2}} \\](https://tex.z-dn.net/?f=y%28t%29%3D0.3%2B%5Cfrac%7Bv%7D%7B%5Csqrt%7B2%7D%20%7Dt%20-4.9t%5E%7B2%7D%20%5C%5C188%3D%5Cfrac%7Bvt%7D%7B%5Csqrt%7B2%7D%7D%20%5C%5C)
solving the eq we get
v=42.9 m/s
b) <em>here,</em>
![t=\frac{116\sqrt{2} }{42.9}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B116%5Csqrt%7B2%7D%20%7D%7B42.9%7D)
when put in y(t) it gives y=44.6 m so result is
h=44.6-3= 41.6m
