n200080 [17]

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.

A car drives 215km east and then 45km north. What is the magnitude of the cars displacement? Round you answer to nearest whole n
kifflom [539]

Answer: 219.65\ \text{km}

Explanation:

Given

Car drives 215 km east and then 45 km North

Displacement is East direction is

\Rightarrow \vec{r_1}=215\hat{i}

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

\Rightarrow \vec{r_{21}}=45\hat{j}

Net displacement is \vec{r_2}

\Rightarrow \vec{r_2}=\vec{r_1}+\vec{r_{21}}\\\Rightarrow \vec{r_2}=215\hat{i}+45\hat{j}

Magnitude of the displacement is

 \Rightarrow \left | r_{2} \right |=\sqrt{\left ( 215 \right )^2+\left ( 45 \right )^2}\\\Rightarrow  \left | r_{2} \right |=\sqrt{48250}\\\Rightarrow  \left | r_{2} \right |=219.65\ \text{km}

A researcher is using a particle accelerator in an experiment studying isotopes. How can the researcher change one isotope into
Illusion [34]
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 />
