Answer:
F = 8.48 x 
N
Step-by-step explanation:
The force on an electron in a magnetic field can be determined by;
F = qvB Sin θ
where: e is the electron, v is its velocity, B is the measure of the magnetic field, and θ is the angle of its path.
Thus,
q = -1.6 x 
C
v = 106 m/s
B = 0.5 T
θ = 
So that,
F = 1.6 x x 106 x 0.5
= 8.48 x N
The force on the electron crossing the uniform magnetic field is 8.48 x N.
Given
81 red balls
Number of balls per row = Number of rows
Procedure
b = Number of balls
r = Number of rows
T = Total number of balls
b = r
![\begin{gathered} T=b\cdot r \\ Given\text{ b=r} \\ T=b^2 \\ b=\sqrt[]{T} \\ b=\sqrt[]{81} \\ b=9 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20T%3Db%5Ccdot%20r%20%5C%5C%20Given%5Ctext%7B%20b%3Dr%7D%20%5C%5C%20T%3Db%5E2%20%5C%5C%20b%3D%5Csqrt%5B%5D%7BT%7D%20%5C%5C%20b%3D%5Csqrt%5B%5D%7B81%7D%20%5C%5C%20b%3D9%20%5Cend%7Bgathered%7D)
The answer is:
Number of rows = 9
Number of balls = 9
1kg = 1000g
4 apples = 1000g
1 apple = 1000/4
1 apple = 250g
Answer:
option 3
Step-by-step explanation:
You can see by inspection that the slope of this line is m = -1/4.
Thus, the equation of this line is y = (-1/4)x.
