Given that,
A charged particle enters a magnetic field with an angle theta .
If ![\theta=90^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%3D90%5E%7B%5Ccirc%7D)
We know that,
If the angle is 90° then the charged particle enters perpendicular to the B.
B is magnetic field.
The charged particle will be follow of the circular path.
If the angle is greater than 0 and less than 90° then the charged particle will be show the helical path.
Hence, This is required answer.
Force = change in momentum / impact time
= mass (change in velocity) / impact time
= 0.07 (0.5-0) / 0.5
= 0.07N
Answer:
The current is 7.87 A.
Explanation:
Given that,
Length = 0.250 m
Magnetic field ![B= 6.10\times10^{-2}\ T](https://tex.z-dn.net/?f=B%3D%206.10%5Ctimes10%5E%7B-2%7D%5C%20T)
Magnetic force = 0.120 N
We need to calculate the current
Using formula of magnetic force
![F=BIL](https://tex.z-dn.net/?f=F%3DBIL)
![I=\dfrac{F}{BL}](https://tex.z-dn.net/?f=I%3D%5Cdfrac%7BF%7D%7BBL%7D)
Where, B = magnetic field
I = current
l = length
F = force
Put the value into the formula
![I=\dfrac{0.120}{6.10\times10^{-2}\times0.250}](https://tex.z-dn.net/?f=I%3D%5Cdfrac%7B0.120%7D%7B6.10%5Ctimes10%5E%7B-2%7D%5Ctimes0.250%7D)
![I=7.87\ A](https://tex.z-dn.net/?f=I%3D7.87%5C%20A)
Hence, The current is 7.87 A.
Answer:
21 mpg
Explanation:
So the distance in miles that his car could cover within gas fill up is the difference in odometer reading
d = 54008 - 53762 = 246 miles
So if it takes 11.8 gallons of gas to cover 246 miles then his mile per gallon can be calculated as
246 / 11.8 = 20.85 mpg
Answer: cause yes they can
