Complete Question
A uniform electric field of magnitude 144 kV/m is directed upward in a region of space. A uniform magnetic field of magnitude 0.38 T perpendicular to the electric field also exists in this region. A beam of positively charged particles travels into the region. Determine the speed of the particles at which they will not be deflected by the crossed electric and magnetic fields. (Assume the beam of particles travels perpendicularly to both fields.)
Answer:
The velocity is 
Explanation:
From the question we are told that
The magnitude of the electric field is 
The magnetic field is 
The force due to the electric field is mathematically represented as
and
The force due to the magnetic field is mathematically represented as
Now given that it is perpendicular , 
=> 
=> 
Now given that it is not deflected it means that
=> 
=> 
substituting values
When the tire is on the car, the pressure is greatest INSIDE the tire,
in that dark chamber where the captive air is trapped. It is the same
pressure at every point inside there, and if it isn't greater than the
pressure OUTSIDE the tire, then you've got a flat.
Answer: No
Explanation: Once you bounce the ball it will go higher and then it will slowly come back down
A. Oscillating magnetic fields are parallel to oscillating electric fields, which are perpendicular to the direction of wave motion.
Answer:
The magnitude of the resistive force exerted by the water is 
newtons.
Explanation:
By First and Second Newton's Law, the resistive force exerted by the water on the cruise ship has the same magnitude of forward thrust, with which it is antiparallel to. The equation of equilibrium for the luxury liner is:
(Eq. 1)
Where:
- Forward trust, measured in newtons.
- Resistive force exerted by the water, measured in newtons.
From (Eq. 1), we get that: (
)
The magnitude of the resistive force exerted by the water is newtons.
