Answer:
Option c) mass
Explanation:
With the increase in energy in energy of an object there will be an increase in its mass.
Also from Einstein's mass-energy equivalence,
where
m = mass of the object
c = speed of the object (usually speed of light or close to it)
which states that energy and mass are inter convertible.
From which it can be concluded that if an object acquires additional energy, it also acquires additional mass.
As we know that speed of sounds is given as
here we know that
t = 23 degree C
now from above equation we will have
now we also know that distance between two consecutive resonance length is half of the wavelength
now we know that
so frequency will be 786 Hz
Answer:
<em>300 W</em>
<em></em>
Explanation:
power of each bulb P = 75 W
voltage in the circuit = 120 V
we know that electrical power P = IV ....1
and V = IR
we can also say that I = V/R
substituting for I in equation 1, we have
P = ....2
The total total power in the circuit = 75 x 2 = 150 W
from equation 2, we have
150 =
R = = 96 Ω this is the resistance of the whole circuit.
This resistance is due to the two light bulbs, for each light bulb since they are arranged in series
R = 96/2 = 48 Ω
From P =
for each light bulb, power is
P = = <em>300 W</em>
Answer: It leads to a front. A front is.., I don't know how to explain it, so I'll add a picture. Fronts are made out of clouds and usually bring rain. So the answer is C: The formation of clouds and rain.
