Answer:
Resistance, R = 8624.18 ohms
Explanation:
It is given that,
The emf of the circuit,
Capacitance of the capacitor,
Voltage across the capacitor, V = 10 V
Time for which the wipers are to operate. The formula for the voltage across the voltage is given by :
So, the value of resistance used in the charging circuit is 8624.18 ohms. Hence, this is the required solution.
Zero minute
Because the traveling boat is faster .
And this is my answer
Answer:
2.7x10⁻⁸ N/m²
Explanation:
Since the piece of cardboard absorbs totally the light, the radiation pressure can be found using the following equation:
<u>Where:</u>
: is the radiation pressure
I: is the intensity of the light = 8.1 W/m²
c: is the speed of light = 3.00x10⁸ m/s
Hence, the radiation pressure is:
Therefore, the radiation pressure that is produced on the cardboard by the light is 2.7x10⁻⁸ N/m².
I hope it helps you!
Answer:
Explanation:
Given that,
The temperature of atom is 21°C
θ = 21 + 273 = 294K.
Then, from kinetic theory,
The kinetic energy of individual elements is
K.E = 2kT/3
k is Boltzmann constant
k = 1.38 × 10^-23 J/K•particle
Then,
K.E = 2 × 1.38 × 10^-23 × 294 / 3
K.E = 2.7048 × 10^-21 J/particle
Each particle of hydrogen is 5.64 × 10²¹ particle
Total K.E = 2.7048 × 10^-21 × 5.64 × 10²¹
Total K.E = 15.26 J
