Answer:
Explanation:
First off, this lens is concave. Second, the image is obviously smaller, and third, the only thing that is NOT obvious, is the fact that real images are always upside down and virtual images are always right-side-up. So the choice you're looking for is D.
Answer: 
Explanation:
Given
Car drives 215 km east and then 45 km North
Displacement is East direction is

Now, the displacement from that to 45 km North is given by

Net displacement is 

Magnitude of the displacement is

The researcher can change one isotope into a different isotope of the same element by ADDING OR REMOVING NEUTRONS.
Isotopes refers to two or more forms of the same element, which have the same number of protons but different number of neutrons. The difference in the number of neutrons of a particular element is what brings about isotopes, thus, isotopes can be created by removing or adding neutrons to a particular element.<span />
Answer:
Distance is 800 m and Displacement is 0 m
Explanation:
Total Distance
= 400(2)
= <u>800</u><u> </u><u>m</u>
Total Displacement
= <u>0</u><u> </u><u>m</u> since she returns to the same spot
B: Gravity.
The force of gravity will pull the car down the hill. The weight/mass of the car also helps this.
