Answer:
Explanation:
The interaction of the piece of copper and water means that the first one need to transfer heat in order to reach a thermal equilibrium with water. Then:
After a quick substitution, the expanded expression is:
The final temperature of the system is:
Time= 20 minutes= 20*60=1200 s
Charge=current*time=12*1200=14400 C
I think is c because your seeing how your using you’re time.
Answer:
With a slower speed-perhaps 5 cm/s answer is c
The angle the velocity of the electron make with the magnetic field is sin(∅) = 90° answer.
The equation F = qv X B may be damaged down into two elements, the significance and the path. The importance is given by F = qv B sin(∅),
Magnetic field = 1. 25-tesla
F = qv B sin(∅)
= sin(∅) = F/qv B
sin(∅) = qv X B/qv B
sin(∅) = 90° answer.
The most importance of the magnetic pressure appearing at the electron whilst its velocity v is perpendicular to B i.e magnetic discipline. The route of the force acting on the electron is the course the palm of the left hand faces. The path of the magnetic area, the direction of the transferring rate, and the route of the pressure on the particle are all perpendicular to each other.
