Dominoes does because when you hit one, it knocks over the next one, and so on, so forth. The same type of pattern happens in a wave.
P = IV
I = P/V = 30 / 120 = 0.25 A.
Current = 0.25A
Answer:
Magnification will be equal to 3
Explanation:
We have given focal length of the converging lens
Focal length of the diverging lens
Object is placed 40 cm to the length of the converging lens d = 40 cm
Combination of the focal length will be equal to
F = 60 cm
So combination of the focal length will be 60 cm
Magnification is given by
So magnification will be equal to 3
Answer:
The answer to your question is: 13.2 m/s
Explanation:
final speed (fs) = 77 m/s
t = 6.5 s
gravity (g) = 9.81 m/s2
initial speed (is) = ?
Formula
fs = is + gt from this equation we clear "is" = fs - gt
Substitution is = 77 - (9,81)(6.5)
Process is = 77 - 63.8
is = 13.2 m/s
The momentum of the
x-ray photon is p = h/lambda . Lambda is the wavelength (0.30nm=3x10^(-9)m) and
h is Planck's constant,(h=6.62607004 × 10-34<span> m2 kg / s).The
momentum is: 2.2 x 10^(-25).</span>
The momentum can be calculated
also as: p=mv, where m is the mass of the electron and v is the speed.
So v=p/m,p is known,and
also the mass of the electron (m=9.10938356 × 10-31<span> kilograms).</span>
v=2.2 x 10^(-25)/9.10938356
× 10-31<span> kilograms=0.24 x 10^6 m/s</span>
