The bus and the truck have the same velocity.
Also, Valerie and Owen have the same velocity.
A eclipse starts when one object in space is blocking an observer. Most commonly known as the moon blocking the sun. For us having a visual on eclipses we normally have two eclipses. We have the solar eclipse and the lunar eclipse. These are both very important on the timing and the cycles of the moon. A solar eclipse happens when the moon moves in front of the sun. This will cause a shadow to fall on only a few certain places on earth. Then a lunar eclipse is when the Sun, moon, and earth are perfectly aligned. With the earth being the middle the Sun casts its rays and causes a huge shadow on the moon.
Hope this helped!
Answer:
0.003333 s to 0.000125s or from 3.33ms to 0.125ms wher m is for milli
1.1m to 0.04125 m
Explanation:
T= 1/f=
if f= 300Hz then T = 1/300 =0.003333 s
if f= 8000 then T= 1/8000 = 0.000125s
now v=f×wave length
or wavelength = speed/ frequency
when f = 300 Hz
wavelength = 330/300=1.1 m
wavelength = 330/8000 = 0.04125m
note : i have taken speed of sound as 330 m/s you can take any value given in between 330m/s to 340m/s
Answer:
The drawing is attached below.
Explanation:
According to the drawing, we can see that the point "0" marked on the mirror, is the point that allows the formation of an angle between Vittorio's eyes and the place where his shirt logo is. In summary, the point on the mirror that needs to be cleaned, so that Vittorio can see only the logo of his shirt, is the point that represents equal vertical distances between Vittorio's eyes and the shirt's logo, since these distances present the same angle.
Answer:
6.4×10⁻¹⁹ C
Explanation:
From the question,
V = E×d.............. Equation 1
Where V = electric potential, E = Electric Field, d = distance moved by the particle.
Given: E = 75 N/C, d = 10 m.
Substitute into equation 1
V = 75×10 = 750 V.
Also Using,
W = qV.................. Equation 2
W = Work done by the particle when it moves, q = Particles charge
make q the subject of the equation,
q = W/V............ Equation 3
Given: W = 4.8×10⁻¹⁶ J, V = 750 V
Substitute into equation 3
q = 4.8×10⁻¹⁶/750
q = 6.4×10⁻¹⁹ C
