The frequency is the number of waves per unit time
Refer to the diagram shown below.
Define unit vectors along the x and y axes as respectively
Then the three successive displacements, written in component form, are respectively
The total displacement for the first leg of the trip is
Answer:
or (-0.6, 0.8)
Answer:
Magnetic field is the strength of magnetism created by a magnet, whereas the magnetic force is the force due to two magnetic objects. The concepts of magnetic field and magnetic force are widely used in fields such as classical mechanics, electromagnetic theory, field theory and various other applications.
Explanation:
the wavelength equation is
speed (of light in this
case)= wavelength (m) x frequency
3x10^8m/s / .07m = f
frequency= 4 285 714 286
hertz
b) Total distance= 4.8 km
(4,800 m)
Speed = 3x10^8 m/s
d=st
t= d/s
t= 4,800 m/3x10^8m/s
<span>t= 1x10^-5 seconds</span>
<u>Given that</u>
Speed = 60 Km/hr
In one hour, how much distance travelled by car
We know that
Distance = Speed × time
S = 60 × 1
S = 60 Km
In one hour car will travel 60 Km
