Answer:
The magnitude is 
The direction is the positive x axis
Explanation:
From the question we are told that
The electric field is E = 450 V/m in the negative y ‑direction
The speed of the proton is 
in the positive z direction
Generally the overall force acting on the proton is mathematical represented as
Now for the beam of protons to continue un-deflected along its straight-line trajectory then 
So
=> 
Generally from unit vector cross product vector multiplication
So the direction of B (magnetic field must be in the positive x -axis )
So
=> 
=> 
=> 
=>
=> 
<span>The correct answer is B. Inverted image. This is because of all the lenses and light refractions and what not. The same things happens with our eyes except our brains fix the inverted image automatically. Since there are no brains in a projector, you have to fix it on your own by putting it in reverse.</span>
Answer: dv/dt = 0
Explanation: Acceleration has to do with when you are changing velocity. since velocity is a speed and a direction you only accelerate when you change speed or change direction or change both in other words you are not accelerating when you are moving in a constant speed and at a specified direction. E.g driving Eastward at a constant speed of 24m/s, such scenario is a case of not accelerating that is acceleration is zero.
38*10=380 N
To be more exact, 38 should be multiplied by 9.8 instead of 10.
