HELP PLEASE I need to finish this asap
ELEN [110]

Answer:

I'm not 100% sure, but I think the answer would be the first one because there's a force pushing the object in every direction, so they would cancel eachother out and make the object stay in the same place.

hich one of the following statements could be an operational definition of electric current?View Available Hint(s)Which one of t
klemol [59]

Answer:

it is True as the operational definition of electric current.

Explanation:

The definition of electric current is

         I = dQ / dt

By convention the direction of the current is the direction in which a positive charge flows.

The initial expression is the derivative that is the change of the load in the unit of time and this occurs in a given cross-sectional cable.

The proposed definition is the same as this, so it is True as the operational definition of electric current.

An object is moving at a constant velocity of 10 m/s for 5 seconds. What is
german

initial velocity (u)=0m/s

final velocity (v)=10m/s

time( t)=5s

acceleration (a)=v-u÷t

acceleration (a)=10-0÷5

acceleration (a)=10÷5

acceleration (a)=2

therefore acceleration (a)=2m/s

What is the average emf induced in a circular wedding ring of diameter 2.2 cm if the ring is at the center of the MRI magnet coi
Minchanka [31]

Missing information

Consider a superconducting MRI magnet for which the magnet field decreases from 8.0 T to nearly 0 in 20 s

Answer:

0.152 mV

Explanation:

Change in magnetic field, dB=8-0=8 T

Time interval, dt=20 s

Diameter of ring= 2.2cm hence radius is 1.1 cm equivalent to 0.011

\epsilon=nA\frac {dB}{dt} where n is the number of terms and for this question n=1 and A is area which is given by \pi r^{2} hence

\epsilon=n\pi r^{2} \frac {dB}{dt} and substituting the values  

\epsilon=1\pi 0.011^{2}\times \frac {8}{20}=1.52\times 10^{-4} V=0.152 mV

Therefore, induced emf is 0.152 mV
