The answer is kilometers.
The most rapid period of growth and development occurs during infancy. Physical changes include doubling of birth weight, increased height, and development of sight and hearing.
I hope this helps! :)
Given:
The force of attraction is F = 48.1 N
The separation between the charges is
Also, the magnitude of charge q1 = q2 = q.
To find the magnitude of charge.
Explanation:
The magnitude of charge can be calculated by the formula
Here, k is the Coulomb's constant whose value is
On substituting the values, the magnitude of charge will be
Thus, the magnitude of each charge is 9.91 x 10^(-4) micro Coulombs.
-- Resistance can be useful among the population of a repressive government.
Although it can be dangerous for those who resist, it can also exert pressure
against the regime to alter its repressive practices.
-- Resistance can also be useful in electronic circuits. "Lumped" components with
known numerical values of resistance are used to divide voltage, limit current, and
dissipate controlled amounts of electrical energy.
Answer:
(a) The ratio of the pressure amplitude of the waves is 43.21
(b) The ratio of the intensities of the waves is 0.000535
Explanation:
Given;
density of gas, = 2.27 kg/m³
density of liquid, = 972 kg/m³
speed of sound in gas, = 376 m/s
speed of sound in liquid, = 1640 m/s
The of the sound wave is given by;
Where;
is the pressure amplitude
(b) when the pressure amplitudes are equal, the ratio of the intensities is given as;
