<span>The vertical velocity (vy) is -569 meter/second.</span>
Answer:
These fields have electric and magnetic energy, therefore the light wave carries energy.
it does not transport matter
Explanation:
Light is an electromagnetic wave formed by the oscillation of electric and magnetic fields.
These fields have electric and magnetic energy, therefore the light wave carries energy.
But the wave does not need matter for its movement, which is why it transports matter. If we use the criterion of special relativity the mass of a light wave that travels at speed must be zero, so with this criterion it does not transport matter either
22 ft/s^2.
explanation: In this case, the velocity has increased by 60 mph in 4 seconds, so the average increase is 60/4 = 15 mph every second, or 15 mph/s.
Usually, you will want to use the same units of time throughout. In this case, you could multiply by the number of seconds in an hour to find out the change in velocity if it carried on travelling for that length of time. This would give the acceleration in units of mph/h, or mph^2.
If you want the answer in feet/s^2, then take your 15 mph/s answer, multiply by the number of feet in a mile (to get it to feet per hour per second) then divide by the number of seconds in an hour to get it to feet per second per second, or feet/s^2.
You should get 22 ft/s^2.
