The balance of oxygen and carbondioxide is maintained in the atmosphere by the oxygen released by plants during photosynthesis and carbondioxide released by human,animals etc. The balance of oxygen and carbondioxide is made due to respreration and photosinthesis.
Answer:
C. X: Allows current to flow into the commutator
Y: Conducts current to the armature and reverses direction of current
Explanation:
Carbon brush is a motor brush that acts as the conducting block for current between the stator and the rotor of a motor.It is made of carbon blocks.The brush is held in place using a spring that ensures its contact position with the commutator.The commutator prevents the torque on the motor from reversing whenever the coil is rotating in the magnetic field.
Carbon cycle am pretty sure it that
I think is True! Is the best answer. Because the trumpet it make them sounds like the lips with the musician and it vibrate.
Answer:
<em>I = 0.75 Amp</em>
Explanation:
<u>Ohm's Law</u>
Ohm's law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points. The constant of proportionality is called the Resistance (R) of the conductor.
The formula can be expressed as:
V = I.R
The intensity of the current through a resistor can be calculated by solving the equation for I:
A flashlight bulb is an example of a resistor with the specific task to emit light when it's hot enough.
The potential difference (or voltage) is V=6 V and the resistance is R=8Ω, thus the current is:
I = 0.75 Amp
