You should have the velocity as a function of time either given explicitly or implicitly (a graph)
v = ds/dt (differentiating the position vector)
integrating the acceleration.
you can use impulse or work and energy principle and also newton law of motion to find acceleration then velocity
NOT SURE IF THAT WHAT YOU WANT.
Answer:
I= 1.616 KA
Explanation:
Given that
L = 2.2 m
N= 1300 turns
r= 30 cm
B= 1.2 T
We know that magnetic field in solenoid given as
![I=\dfrac{BL}{\mu_o N}](https://tex.z-dn.net/?f=I%3D%5Cdfrac%7BBL%7D%7B%5Cmu_o%20N%7D)
Now by putting the values
![I=\dfrac{1.2\times 2.2}{4\pi \times 10^{-7} \times 1300}\ A](https://tex.z-dn.net/?f=I%3D%5Cdfrac%7B1.2%5Ctimes%202.2%7D%7B4%5Cpi%20%5Ctimes%2010%5E%7B-7%7D%20%5Ctimes%201300%7D%5C%20A)
I= 1616.03 A
So the current is 1616.03 A.
I= 1.616 KA
Answer:
18 grams
Explanation:
The mass of an object is the object's fundamental property. It is the amount or quantity of mater in the object. Irrespective of the object's location or the gravitational force applied on the object, the mass of an object remains the same. In other words, the mass of an object is the same everywhere.
The mass should however not be confused with its weight which depends on the mass and the gravitational force applied on it.
In summary, whether on earth or in the moon, the mass of an object remains the same. If the mass of the object is 18 grams on earth, it will also be 18 grams in the moon.
Answer:
![7.2\cdot 10^{-4} N/m](https://tex.z-dn.net/?f=7.2%5Ccdot%2010%5E%7B-4%7D%20N%2Fm)
Explanation:
The magnetic force between two current-carrying wires is given by:
![\frac{F}{L}=\frac{\mu_0 I_1 I_2}{2\pi r}](https://tex.z-dn.net/?f=%5Cfrac%7BF%7D%7BL%7D%3D%5Cfrac%7B%5Cmu_0%20I_1%20I_2%7D%7B2%5Cpi%20r%7D)
where
is the vacuum permeability
I1 and I2 are the two currents
r is the distance between the wires
Here we have:
![I_1 = I_2 = 12 A\\r = 4 cm = 0.04 m](https://tex.z-dn.net/?f=I_1%20%3D%20I_2%20%3D%2012%20A%5C%5Cr%20%3D%204%20cm%20%3D%200.04%20m)
Substituting into the equation,
![\frac{F}{L}=\frac{(4\pi \cdot 10^{-7})(12)(12)}{2\pi (0.04)}=7.2\cdot 10^{-4} N/m](https://tex.z-dn.net/?f=%5Cfrac%7BF%7D%7BL%7D%3D%5Cfrac%7B%284%5Cpi%20%5Ccdot%2010%5E%7B-7%7D%29%2812%29%2812%29%7D%7B2%5Cpi%20%280.04%29%7D%3D7.2%5Ccdot%2010%5E%7B-4%7D%20N%2Fm)
