Answer:
Centripetal acceleration will be equal to
Explanation:
We have given time taken to cover 180° is 0.5 sec
So time taken by 360° is equal to = 2×0.5 = 1 sec
Radius of the circle r = 0.520 m
So distance
So velocity
We have to find the centripetal acceleration
Centripetal acceleration will be equal to
So centripetal acceleration will be equal to
If an electric circuit has zero Ampere (0A) of current running through it, then the voltage must be zero.
<h3 /><h3>What is ohm's law?</h3>
At constant temperature, Ohm's law says that the current flowing through an electric circuit is directly proportional to the voltage
Also, the current flowing through an electric circuit is inversely proportional to the resistance in the electric circuit.
This means that the magnitude of voltage (potential difference) is significantly reliant on the value of current flowing through an electric circuit.
This formula expresses Ohm's law mathematically.
V=IR
Where:
V is the voltage is measured in volts.
I denote the current in amperes.
R denotes the resistance in ohms.
Finally, if an electric circuit has zero ampere (0A) of current flowing through it, the voltage must also be zero.

Answer: Bohr's model
Explanation:
The Bohr's model is also known as the solar system model which describe that an atoms are basically imagine in the form of solar system. The Bohr's model basically describe about the atoms that it consist of nucleus with the number of electron in an orbit by using the electrostatic attraction.
The Bohr's model are introduced for overcoming the drawback in the Rutherford model as he proposed an idea that at different energy levels the electron can revolve in certain orbits around nucleus.
Answer:
= 4,574 10⁻⁵ m
Explanation:
The interference pattern for a two slit system is given by
d sin θ = m λ constructive interference
d sin θ= (m + ½) λ destructive interference
In general and also in this case the screen is far from the slits, so the TT-free can approach the TT
tan θ = y / L
Let's replace
d y / L = m λ constructive interference
d y / L = (m + ½) λ destructive interference
Let's start when there is constructive interference
They give us the frequency of light, let's find the wavelength
c = λ f
λ = c / f
λ = 3 10⁸ / 6.32 10¹⁴
λ = 4.7468 10⁻⁷ m
Let's take the opportunity to reduce the SI system
L = 87 cm = 0.87 m
y = 3.16 cm = 0.0316 m
Now we can find the separation of the slits
d = m λ L / Y
d = 3 4.7468 10⁻⁷ 0.87 / 0.0316
d = 3.92 10⁻⁵ m
We already have all the data, now let's use the destructive interference equation and find
d / L = (m + ½) λ
= (m + ½) λ L / d
= (3 + ½) 4.7468 10⁻⁷ 0.87 / 0.0316
= 4,574 10⁻⁵ m
