Answer:
The current is 0.951 A
Solution:
As per the question:
Capacitance of the capacitor, C =
Resistance of the circuit, R = 14.0
Voltage of the battery, V = 10.0 V
Now, when the charge become one-fourth of its initial value, the amount of current flowing is given by:
(1)
where
q' =
Now,
The current is given by:
(2)
Also,
Now, using the value of I = 0.714 A
To solve this problem we will apply the Wien displacement law (in honor of Wilhelm Wien) which is a law of physics that states that there is an inverse relationship between the wavelength at which the emission peak of a body occurs Black and its temperature. Mathematically, the law is:
Here,
T = Temperature
We know at the same time that the range of red to infrared wavelength is
Calculating each quasi infinite point of this range would be somewhat complex, so it is easier to replace temperatures and see if the temperature falls on the range. We can realize that the first option is the correct one, because:
Therefore the temperature is A. 3500K
Answer:
The moon and sun cause tidal bulges to move around the planet in perfect sync and unison.
Explanation:
However, do not consider these to be large oceans of water moving in relation to continents. Only the fluctuations in water level—the water's surface profile—follow the moon's and sun's positions in the sky.
Answer:
Work done, W =1520 J
Explanation:
We have,
The brakes on a bicycle apply 95 N of force to the wheels. When the brakes are applied, the bicycle comes to a stop in 16 m.
It is required to find the work done by the brakes on the wheels. We know that the product of force and displacement is equal to the work done. It is given by :
So, the work done by the brakes is 1520 J.
Answer:
Explanation:
The Schwarzschild radius can be calculated as follows:
Where, <em>G</em> is the gravitational constant, <em>M</em> is the mass and <em>c</em> is the speed of light.
Mass of sun is 1.98×10³⁰ kg
