<span>Since frequency and wavelength have inverse relationship. It can be expressed by the equation:
ν.λ = c
Where,
v = frequency of the electromagnetic wave.
λ = it's wavelength
c = the speed of light in a vacuum.
v = 2.00 Ghz x 10^9 Hz / 1 Ghz = 2.00 x 10^9 Hz
that means that in one second it covers 2.00 x 10^9 cycles.
λ = 3.10^8 m/s / 2.00 x 10^9 /s = 1.25E-10 nanometers</span>
Answer: the block at the right lands first
Explanation:
<span>If a plane has a velocity of 300 km/h and a tailwind of 20 km/h, then the vectors of both forces would add (assuming that the tailwind is blowing exactly at the airplanes back) to a total of 320 km/h. Hope it helps

Answer:
Speed of 0.08 kg mass when it will reach to the bottom position is 1.94 m/s
Explanation:
When rod is released from rest then due to unbalanced torque about the hinge the system will rotate
Now moment of inertia of the system is given as
now we have
now we have
so we have
now by energy conservation we can say work done by gravity must be equal to change in kinetic energy
so we have
Now speed of 0.08 kg mass when it reaches to bottom point is given as
Answer:
0.975 m
Explanation:
The center of mass y = ∑m₁y₁/∑m₁ where m₁ = the individual masses and y₁ = the y - coordinates of the individual masses
So,
y = (2.02 kg × 3.03 m + 2.92 kg × 2.43 m + 2.53 kg × 0 m + 4.02 kg × -0.501 m)/(2.02 kg + 2.92 kg + 2.53 kg + 4.02 kg)
y = (6.1206 kgm + 7.0956 kgm + 0 kgm - 2.01402 kgm)/11.49 kg
y = 11.20218 kgm/11.49 kg
y = 0.975 m
So, the y- component of the center of mass of these objects is 0.975 m
