Answer:
Concept: Physics analysis
- We have a distance vs time graph
- That indicates that we are analyzing the distance traveled by either a person or a particle
- The runner starts at 4 meters and over the interval of a second runs to 12 meters reaching the 16 meter mark. The runner stood at 16 meter mark for one full second and then runs back 10 meter over the course of one second reaching 6 meter. The runner runs forward again for a second traveling 6 meters, ending at the 12 meter mark.
Answer:
The angle is 
Explanation:
From the question we are told that
The length of the wire is 
The current is 
The magnetic field strength is 
The magnitude of the magnetic force is 
Generally the magnetic force exerted on the wire is mathematically represented as

![\theta =sin^{-1} [ \frac{ F_b }{I * l * B } ]](https://tex.z-dn.net/?f=%5Ctheta%20%3Dsin%5E%7B-1%7D%20%5B%20%5Cfrac%7B%20F_b%20%7D%7BI%20%20%2A%20%20l%20%20%2A%20%20B%20%7D%20%5D)
substituting values
![\theta =sin^{-1} [ \frac{ 0.18 }{ 2.0 * 0.6 * 0.3 } ]](https://tex.z-dn.net/?f=%5Ctheta%20%3Dsin%5E%7B-1%7D%20%5B%20%5Cfrac%7B%200.18%20%7D%7B%202.0%20%20%20%2A%20%20%200.6%20%20%2A%20%20%200.3%20%7D%20%5D)
The process of flask becoming cold is due to endothermic reaction.
Answer: Option B
<u>Explanation:</u>
So two kinds of heat transfer can be possible in any chemical reaction. If the sample is considered as system and the sample container is considered as the surrounding, then heat transfer can occur between them.
If the heat is transferred from the surrounding to the system , then it is an endothermic reaction. And in those cases, the sample holder will be becoming colder. This is because the heat from the surrounding that is the container will be utilized to complete the reaction.
While when there is transfer of heat from the system to surrounding , it will be exothermic reaction and the beaker will be getting hot in this process. So in the present case, the container is becoming cold because of occurrence of endothermic process.
Answer:
calm down please its not that serious maybe no one saw it yet
Explanation:
If a red blood cell is 7 x 
m in size, it means that such a cell is 7 microns or micrometer in size. The unit that completes the sentence will, thus, be microns or micrometer.
According to international system of measurement:
m = decimeter
m = centimeter
m = millimeter
m = micrometer or micron
m = nanometer
Thus, a measurement of 7 x m is the same is 7 micons or 7 micrometer.
