Answer:
d) F2 = -F1.
Step-by-step explanation:
According to Coulomb's law of forces on electrostatic charges, the force of attraction is proportional to the product of their charges, and inversely proportional to the square of their distance apart.
What this law means is that both particles will experience an equal amount of force on them, due to the presence of the other particle. This force is not just as a result of their individual charges, but as a result of the product of their charges. Also, the force is a vector quantity that must have a direction alongside its magnitude, and the force on the two particles will always act in opposite direction, be it repulsive or attractive.
Answer:
0.0862 = 8.62% probability that Heather reaches in the bag and randomly selects 2 peanut butter cookies from the bag
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcoes.
The order in which the cookies are selected is not important, so we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
Desired outcomes:
2 peanut butter cookies, from a set of 4. So
Total outcomes:
2 cookies from a set of 5+8+9+4 = 26. So
Probability:
0.0862 = 8.62% probability that Heather reaches in the bag and randomly selects 2 peanut butter cookies from the bag
