Here observer is moving along with an electrical charge
now magnetic field on a moving charge is given by equation
electrical force on a moving charge is given by formula
so here we can say when observer is moving with the charge it will have two forces on it
1. magnetic force due to existing magnetic field
2. electric force due to electric field
so here he must have to experience both type of field presence
So here correct answer must be
<em>C- electric and magnetic fields </em>
No, he should place the He atom and energy on the right, and the H atoms and the heat and energy on the left.
Explanation:
Below is an attachment containing the solution.
Carbon-14 is naturally created with the interaction of high-energy cosmic rays with atmospheric nitrogen. As part of the atmosphere, living organisms take in the carbon and incorporate this into living tissues. As long as the organism is alive and breathing, it keeps adding new carbon-14. When the organism dies, it stops gaining carbon-14 - or anything else, of course.
Carbon-14 is slightly radioactive, with a half-life of about 5700 years. If we assume that the atmospheric production of carbon-14 has been steady for the last 100,000 years, we can calculate the approximate age of when the organism died by determining what percentage of carbon-14 still exists in the dead material.
Paleo-archaeologists and anthropologists use this information when studying old cultures and civilizations.
Answer:
Distance piston B = 3 [in]
Explanation:
This problem can be solved using the pascal principle, which is applied for both pressures and volumes. In this case we use the definition of volumes, which says that the volume displaced fluid on one side of the Pistons should be equal to the volume displaced on the other side of the piston.
We know that the volume is equal to the product of an area by a length
![V_{A}=V_{B}\\A_{A}*d_{A}=A_{B}*d_{B}\\2*6=4*d_{B}\\d_{B}=12/4\\d_{B}=3[in]](https://tex.z-dn.net/?f=V_%7BA%7D%3DV_%7BB%7D%5C%5CA_%7BA%7D%2Ad_%7BA%7D%3DA_%7BB%7D%2Ad_%7BB%7D%5C%5C2%2A6%3D4%2Ad_%7BB%7D%5C%5Cd_%7BB%7D%3D12%2F4%5C%5Cd_%7BB%7D%3D3%5Bin%5D)
