You drive from your house to the dry cleaners, which is 12 miles east of your house. You then drive to the grocery store from th
e dry cleaners. The grocery store is 15 miles west of your house. What distance did you cover?
1 answer:
Answer:
39 miles
Explanation:
we will make your house to be the central point in the four cardinal points.
Please follow the diagram on the attachment to get the movement clearly.
First, you move to a dry cleaners 12miles east of your house, and then to a grocery store 15miles west of your house.
This means you must have moved back to your house before going to the grocery which is 15miles west of your house.
so to and fro from your house to dry cleaners = 12*2 = 24 miles.
Then the total distance you cover will be = 24 +15 = 39 miles

Answer:
a) 5.64 C
b) 3.5*10¹⁹ protons
Explanation:
a)
- Since the four metallic objects are identical, and total charge must be conserved, this means that after brought simultaneously into contact so that each touches the others, once separated, total charge must be the same than before being brought in contact.
- But due they are identical, after charges were able to transfer freely between them, the four objects must have the same final charge, i.e. the fourth part of the total charge, as follows:
b)
- This charge will be divided between n protons, since the charge is positive.
- Since each proton carries a charge equal to the elementary charge e, which value is 1.6*10⁻¹⁹ C, we can find the number of protons in excess, doing the following calculation:
-
