Answer:

The magnitude of the electric field at distance r from the point charge q is \dfrac{kq}{r^2}

Explanation:

Suppose, Find E(r), the magnitude of the electric field at distance r from the point charge q.

We know that,

The electric field is proportional to the point charge and inversely proportional to the square of the distance from the charge point .

In mathematically,

E=\dfrac{kq}{r^2}

Where, q = charge point

R = distance from charge point

Hence, The magnitude of the electric field at distance r from the point charge q is \dfrac{kq}{r^2}

Will two separate 50db sounds together constitute a 100db sound explain mathematical
vfiekz [6]
Putting together two distinct 50 dB sound, do not create a 100 dB sound. Since decibels are logarithm of energy, creating two sounds together only makes the energy increase but the logarithm only goes up by somehow little. So increasing the sound by 10 dB, only makes it 10000 times louder because each 10 dB increase in sound makes the sound 10 times louder.

Twice as loud is an increase of 10Log (2) = 3.01 dB. So, 53,01 dB is twice as loud as 50dB.

goblinko [34]

Answer:

C. a clamp light with a 150-W lightbulb placed 25 cm from the radiometer

Explanation:

because the temperature has to be set, meaning it can't change, and it should be a different distance away than the first one.

Hope this helps! Stay safe!
