How can icalculate 3 seconds and 5 meters into a speed?

1 answer:

8 0

To find speed you have to divide distance by time. In this case:

5 meters➗3 seconds = about 1.66666666 and so on m/s.

You could round to 1.67 or 1.7 if you'd like.

A negative charge is moving across a room from south to north. A magnetic field runs from east to west. In what direction is the

erica [24]

Here is your answer

C. towards the floor

REASON:

Using Fleming's Left hand rule we can determine the direction of force applied on a moving charged particle placed in a magnetic field.

The direction of current will be just opposite to the direction of electron(negative charge) because current moves from positive to negative terminal whereas electron moves from negative to positive terminal.

So, direction of current- North to South

Now applying Fleming's Left hand rule we get the direction of force in downward direction, i.e. towards the floor.

Light of wavelength 550 nm falls on a slit that is 3.50 x 10^-3 mm wide. How far from the central . maximum will the first diffr

myrzilka [38]

Λ $= 550 * 10^{-9}\] m.

D = 3.50*10^-6 m.$
$d = 10 m. 

m = 1

2x = ?$

Then you need to find x when n=1
or
$sinθ=λ/w=524x10^-9/0.0033=1.59x10^-4$
≈θ for θ<<1 , so θ= $1.59x10^-4 radians$

Then you can find rhe distance of<span> bright fringe from the center:</span> $d= θD=1.59x10^-4x10m ≈ 1.6 mm$
