The answer is 1.99 × 10⁻¹⁰ m.
To calculate this we will use De Broglie wavelength formula:
<span>λ = h/(m*v)
</span><span>λ - the wavelength
</span>h - Plank's constant: h = 6.626 × 10⁻³⁴ Js
v - speed
m - mass
It is given:
<span>λ = ?
</span>m = 9.11 × 10⁻²⁸<span> g
v = </span>3.66 × 10⁶<span> m/s
After replacing in the formula:
</span>λ = h/(m*v) = 6.626 × 10⁻³⁴ /(9.11 × 10⁻²⁸ * 3.66 × 10⁶) = 1.99 × 10⁻¹⁰ m
Electrons are located outside the nucleus
Answer: Option (b) is the correct answer.
Explanation:
Vitamin C is also called ascorbic acid and it is abundant in fruits and vegetables.
For example, oranges, tomatoes, lemon, etc are rich in vitamin C.
It also helps in increasing immunity and destroys the toxic substances present within our body.
Thus, we can conclude that Vitamin C is abundant in fruits and vegetables, is linked to increased immunity and the destruction of toxic substances within the body.
A pendulum oscillates 40 times in 4 seconds. Find it's time period and frequency.
- The time period
- Its Frequency
Frequency of oscillation is defined as the number of oscillation of a vibrating body per second.It is given by
The time period
The time required to complete one oscillation is known as Time period.
It is given by the inverse of the frequency.
________________
Therefore the frequency is
And the time period is
