Its would be a radio. because it is the only electrical one out of the choices
Assuming an ideal gas, the speed of sound depends on temperature
only. Air is almost an ideal gas.
Assuming the temperature of 25°C in a "standard atmosphere", the
density of air is 1.1644 kg/m3, and the speed of sound is 346.13 m/s.
The velocity can't be specified, since the question gives no information
regarding the direction of the sound.
Answer:
Explanation:
Distance between q1 and q2,d=20 cm
1m =100 cm
Electric force on charge q3 due to charge q1
(away from q1)
Electric force on charge q3 due to charge q2
(attract toward q2)
Net force=
Answer:
A body is abandoned and it is observed that after 4 s it touches the ground. How high was it released?
*the central dogma of life DNA > RNA > Protein
