Answer:
The value for g on Earth is 9.8 m/s/s. The above equation can be used to calculate the velocity of the object after any given amount of time when dropped from rest.

Answer:
The approximate combined sound intensity is
Explanation:
The decibel scale intensity for busy traffic is 80 dB. so intensity will be
, therefore
In the same way for the loud conversation having a decibel intensity of 70 dB.
, therefore
Finally we add both of them , is the approximate combined sound intensity.
As more resistors are added in parallel across a constant voltage source, there are more paths for current to take. So more current dribbles out of the source, and the total current supplied by the source increases.
The power supplied by the battery is (voltage) x (current). So if the voltage is constant and the current increases, the power being supplied must also increase.
<em>choice-c</em>
This is an example of Newton's first law of motion:
An object at rest will remain at rest unless an unbalanced force acts upon it. Similarly, a moving object will remain moving in a straight line at constant velocity unless an unbalanced force acts upon it.
The answer is C.
Answer:
terminal voltage = 1.34 V
power = 2.68 W
Explanation:
given data
voltage E = 1.54 V
current = 2A
internal resistance = 0.100 ohm
to find out
terminal voltage and electrical power
solution
we know terminal voltage formula is
terminal voltage = E - current × resistance
terminal voltage = 1.54 - ( 2 × 100 )
terminal voltage = 1.34 V
and
power is calculated by ohm law
Power = V × current
power = 1.34 × 2
power = 2.68 W
