The RC time constant, also called tau, the time constant (in seconds) of an RC circuit, is equal to the product of the circuit resistance (in ohms) and the circuit capacitance (in farads), i.e.
Here,
R = Resistance
C = Capacitance
Replacing we have that
Therefore the time constant of this circuit is
The ocean doesn't just store solar radiation; it also helps to distribute heat around the globe. When water molecules are heated, they exchange freely with the air in a process called evaporation. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds, often vast distances. In fact, almost all rain that falls on land starts off in the ocean. The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area.
i hope this if not sorry
Answer:
because it emits the most heat thru radiation
Upstream speed = S - 1
Downstream speed = S + 1
Average speed = total distance / total time
Average speed = (S - 1) + (S + 1) / 2
= S
S = 6 miles / 4 hours
S = 1.5 miles per hour
<u>Answer:
</u>
Metal ball will take 0.364 seconds to reach floor.
<u>Explanation:
</u>
Initial height from ground = 65 cm = 0.65 meter
We have equation of motion , 
, s is the displacement, u is the initial velocity, a is the acceleration and t is the time.
In this the velocity of body in vertical direction = 0 m/s, acceleration =acceleration due to gravity = 9.8 
, we need to calculate time when s = 0.65 meter.
Substituting
So it will take 0.364 seconds to reach floor.
