Explanation:
The energy of a wave is given by :
Where
h is Planck's constant
c is the speed of light
is wavelength
Energy is inversely proportional to wavelength. Also, the relation between frequency and wavelength is inverse.
If the frequency is high, the wavelength will be shorter.
Hence, the correct options are :
Higher frequencies have shorter wavelengths.
Shorter wavelengths have lower energy.
Lower frequencies have lower energy.
Answer:
The rate clock is about
F = 8 GHz
Explanation:
f₁ = 4 G Hz , t₁ = 10 s , t₂ = 6s , f₂ = 1.2 f₁
Can organize to find the rate clock the designer build to the target so
X / 4 Ghz = 10 s , 1.2 X / Y = 6 s
X * Y = 10 s ⇒ F = 10 s
1.2 * 4 G Hz = 6 s
F = 10 * ( 1.2 * 4 G Hz ) / 6
F = 10 * ( 1.2 * 4 x 10 ⁹ Hz ) / 6
F = 8 x 10 ⁹ Hz
F = 8 GHz
Answer: yes
Explanation: Assuming a it's moving 20m/s in the west direction and slowing down at a rate of -5m/s² (deceleration), the negative sign would imply the westward direction because -5 west is the same thing as +5 east. So, the boat is moving 20m/s west direction and accelerating at 5m/s² east direction.
Other examples of these are: Cars and and tricycles.
Equilibrium implies that the net force on the body is 0, therefore the body undergoes no acceleration. No acceleration means the velocity doesn't change.
The body's velocity stays constant over time.
