Answer:
speed /wavelength = frequency
f = 3×10*8 /6.5×10*7
f = 4.62

Explanation:
Answer:
1.2 Amps
Explanation:
<em>The question is incomplete, however, according to Ohm's law the current through a conductor between two points is directly proportional to the voltage across the two points.</em>
Given Data
Voltage= 4.4V
Resistance= 5.2 Ohms
V=IR---------------Ohms law
I= V/R
I= 5.2/4.4
I= 1.18
I= 1.2 Amps
Hence the current is 1.2 Amps
Let's assume that ground level is the height 0 meters. The change in potential energy is going to be gravitational potential energy, which is given by PE=mgh.
ΔPE=mgh-mgy
=mg(h-y)
=50(28-0)
=1400 J
