A small point charge carries a charge of +4 x 10-10 C. 7.1 - Calculate the magnitude of the electric field strength at a distance of 30 mm
from the point charge.

7.2- A second point charge of -8 x 10-10 C is placed at position X. Calculate the
magnitude of the force between the charges.

not solvable

step-by-step explanation:

we need more information, or at least an

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25

step-by-step explanation:

think about the doctor who treated the major and the speaker in the short story "in another country." put yourself in the shoes of the doctor, and based on what you read in the story, write what you think his thoughts about the major and the speaker would be. use the following vocabulary in your response and change the form of these words as needed: detached resign withered
