A proton, traveling with a velocity of 4.6 × 106 m/s due east, experiences a magnetic force that has a maximum magnitude of 6.0

Kobotan [32]

Answer:

$B = 0.0815 T$

since the direction of force is along south so the magnetic field must be upwards

Explanation:

Force on moving charge in magnetic field is given as

$F = q(\vec v \times \vec B)$

here we know this is force on proton

so we have

$q = 1.6 \times 10^{-19} C$

$F = 6.0 \times 10^{-14} (-\hat j) N$

also we know that the velocity of charge is

$v = 4.6 \times 10^6 \hat i m/s$

now from above formula we have

$(6.0 \times 10^{-14}) = (1.6 \times 10^{-19})(4.6 \times 10^6)B$

$B = 0.0815 T$

since the direction of force is along south so the magnetic field must be upwards

Name the missing force... Normal <br> Spring <br> Tension <br> Air Resistance

Kay [80]

the missing force is spring force.

The object is hanging from the spring and the spring is stretched by some distance from its equilibrium position. due to this stretch in the spring , a spring force starts acting on the object trying to regain its equilibrium position.

the spring force is given as

F = kx

where F = spring force ,k = spring constant , x = stretch in the spring.

the spring force balances the weight of the object in down direction and hence keeps the block from falling down.

A car traveling at 40 m/s starts to decelerate steadily. It comes to a complete stop in 5 seconds. What is its acceleration? m/s

SCORPION-xisa [38]

Acceleration =

   (change of speed) / (time for the change).

Change of speed = (speed at the end) - (speed at the beginning)

      =    ( zero ) - (40 m/s)

   = -40 m/s .

Acceleration = (-40 m/s) / (5 seconds)

   = -8 m/s² .

When a charge is discharged to the earth, we call it?

Tems11 [23]

Answer:

lightning

Explanation:

correct answer is Lightning because it is the naturally occurring electrostatic discharge, during 2 electrically charge field in atmosphere and on the ground temporarily equalize themselves and they instantly release energy.
As it is released cloud so we called it lightning but a spark is generated when the electric field strength is sufficient to ionize the molecules of air, creating a small conduction path through the air.
This is usually a cascade process, because free electrons accelerate in the electric field and ionize more molecules by colliding.

A coin is rolled in a straight line along a balcony edge at a steady speed of 0.5 m/s. a) Calculate how far the coin rolls in 2.

NemiM [27]

Use this equation (v=Δx/t); plug in velocity (0.500 m/s) and the time (2.4 s), then solve for displacement… (Δx=1.2 m)
