Answer:
the maximum frequency observed is 2.0044 10⁶ Hz
Explanation:
This is a Doppler effect exercise. Where the emitter is still and the receiver is mobile, therefore the expression that describes the process is
f ’=
the + sign is used when the observer approaches the source
typical speeds of a baby's heart stop are around 200 m / min
let's reduce to SI units
v₀ = 200 m / min (1 min / 60 s) = 3.33 m / s
let's calculate
f ’= 2 10⁶ ()
f ’= 2.0044 10⁶ Hz
f ’= 1,9956 10⁶ Hz
therefore the maximum frequency observed is 2.0044 10⁶ Hz
<u>Electromagnetic powers versus Molecules: </u>
Electrons are kept in the circle around the core by the electromagnetic power, in light of the fact that the core in the focal point of the particle is decidedly charged and pulls in the contrarily charged electrons.

<u>Solid Nuclear power versus Molecules: </u>
The solid atomic power holds most standard issue together on the grounds that it limits quarks into hadron particles, for example, the proton and neutron.
<u>Feeble power versus Molecules: </u>
In atomic material science and molecule physical science, the frail cooperation, which is additionally frequently called the powerless power or feeble atomic power, is the instrument of communication between subatomic particles that is liable for the radioactive rot of iotas.

<u>Gravity Vs. Particles: </u>
Gravity influences molecules a similar way it influences all other issue. Each iota makes its own gravitational field which draws in all other issue known to man.
Weight of an object is defined as attraction force due to gravity
so here we will have
now we know that
mass = 15 kg
now acceleration due to gravity is given as
so here acceleration due to gravity is 9.8 m/s^2
B) Temperature.......... Hope it helps, Have a nice day :)
The answer is 68 F. i hope this helps
