Answer:

4940.12 m/s

Explanation:

For the net force on the moving electron to be zero, the Magnetic force must then match the electric force.

Magnetic force = Electric force

Magnetic force = qvB

Electric force = Eq

qvB = Eq

v = (E/B)

E = Electric field = 1.65 kV/m = 1650 V/m

B = Magnetic field = 0.334 T

v = (1650/0.334)

v = 4940.12 m/s

Hope this helps!!

When there's a hazard ahead, it's almost always quicker for you to _________ than to come to a full stop.
TEA [102]

When there's a hazard ahead, it's almost always quicker for you to steer away than to come to a full stop.

<h3>What is an hazard?</h3>

Hazard refers to any obstacle or other feature which causes risk or danger.

Living organisms respond to hazards via the production of adrenaline hormone. This hormone causes a flight response away from the hazard.

Therefore, when there's a hazard ahead, it's almost always quicker for you to steer away than to come to a full stop.

What is inertia? That is all but I need 20 characters to ask lol
damaskus [11]
Inertia, property of a body by virtue of which it opposes any agency that attempts to put it in motion or, if it is moving, to change the magnitude or direction of its velocity. Inertia is a passive property and does not enable a body to do anything except oppose such active agents as forces and torques.

Sam is playing football. She kicks the ball with an average force of 75 N.
damaskus [11]

Answer:

22.5J

Explanation:

Here the force is given. Also, the displacement is given as 30cm.

First we should check if all the values are in their standard form.

Here 30cm should be converted to metre by dividing it with 100.

Which would give us 0.3m

Now we use the equation W=force x displacement =75 x 0.3=22.5J

I hope this satisfies you. If u have any further questions please let me know.

I hope u will follow me and make this the brainliest answer.
