1g-1.5=-4g-4 (distribute 1/2 and -4 inside their respective parenthesis)
1g=-4g-2.5 (add 1.5 to -4)
5g=-2.5 (add 4g to 1g)
g=-0.5 (divide both sides by 5)

15. Find the force on an electron crossing a uniform magnetic field of intensity 0.5 T WILII
EleoNora [17]

Answer:

F = 8.48 x 10^{-18} 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 10^{-19} C

v = 106 m/s

B = 0.5 T

θ = 90^{o}

So that,

F = 1.6 x 10^{-19} x 106 x 0.5

  = 8.48 x 10^{-18} N

The force on the electron crossing the uniform magnetic field is 8.48 x 10^{-18} N.

Lara surveyed all of the 11th grade students at her school about the number of languages they speak and whether or not they have
Bingel [31]

Answer:

57.6% have allergies

42.4% have no allergies

Step-by-step explanation:

We only need to consider the students who speak two languages according to the question.

To find the percent with allergies, divide the number of students with allergies by the total number of students (that speak two languages).

19/33 = 0.5757 = 57.6%

To find the percent without allergies, divide the number of students without allergies by the total number of students (that speak two languages).

14/33 = 0.4242 = 42.4%

Check your work by adding the percentages to make sure they equal 100%

57.6 + 42.4 = 100
