Answer:
Photosynthesis
Light energy from the sun stimulates photosynthesis by green plants. One major component of the carbon cycle is the reduction of the carbon (IV) oxide content in the atmosphere by plants. Plants take in Carbon (IV) oxide to use during the process of making their own food. During this process light energy is absorbed by chlorophyll and is used to convert carbon (IV) oxide and water to glucose.
This glucose is used during respiration by living organisms that give out carbon (IV) oxide. The cycle continues.
Answer:
it's a rule like water !!!!
Explanation:
Most importantly, time appears to run forward always never backwards. in other words there's perceived arrow of time and there's thermodynamic arrow of time, and they always point in a forward direction
Given that,
Number of turns, N = 25
Magnetic field, B = 1.5 T
The coil has a crosssectional area of 0.80 m2
The coil exits the field in 1.0 s.
To find,
Induced emf in the coil.
Solution,
The induced emf in the coil is given by :
So, the induced emf in the coil is 30 V.
Answer:
Change in temperature =7.14° C
Explanation:
Assuming all potential energy of cylinder is converted into heat energy to increase the temperature .
Work done by gravity in first case =m *g*h= 3*10*500=15000
Let quantity of water be 1 kg at 0°C.
Also specific heat capacity of water is =4200 Joule
So potential energy is converted to m*4200*T(1) =15000
T(1)=3.57
Work done by gravity in first case =m *g*h= 9*10*500=45000
Here also potential energy is converted into m*4200*T(2)=45000
T(2)=10.71
Here temperature is increasing.
Thus change in temperature =T(1) -T(2) =7.14° C
Answer:
Z = R, i = V/Z, w = √1 / LC
Explanation:
In an RLC circuit the impedance of the circuit is
Z = √[R² + (
)²
Where
= wL
X_{L} = 1 / wC
They are the reactances of the inductor and the capacitor, in this case the current advances to the voltage in the first and is delayed from the voltage in the second, so when the two values give the same reactance the current goes in phase with the voltage and the impedance is minimal
Z = R
V= i Z
i = V/Z
Therefore the current is maximum, this occurs when
w = √1 / LC
Saying that this is the resonant frequency
