Explanation:
Weak nuclear force:
The interaction between the subatomic particles is called weak nuclear force.
The weak nuclear force is one of the four fundamental forces.
The weak nuclear force is effective at very short distance.
The range and relative strength of weak nuclear force is 10⁻¹⁸ m and 10²⁵ with respect to gravitational force respectively
Deuterium is formed due to the fusion of protons and neutrons under the action the weak force.
Example : Beta decay
Electromagnetic force:
The interaction between the charged particles is called electromagnetic force.
The electromagnetic force is one of the four fundamental forces.
The electromagnetic force is effective at long range distance.
The range and relative strength of electromagnetic force is infinity and 10³⁶ with respect to gravitational force respectively
Example : light
Answer:
The Hubble space telescope.
Explanation:
Hubble is a telescope that observers the sky 24/7 non-stop, which means that for every day of the year it would have made a significant discovery, which of course includes your birthday. Furthermore, you can actually go to NASA website and find out what discovery was made on your birthday! This shows both the vastness of the universe <em>(it really has to be huge for a telescope to have a discovery for each day of the year!) </em> and the ceaseless work of the telescope!
Answer:
y = 52.44 10⁻⁶ m
Explanation:
It is Rayleigh's principle that two points are resolved if the maximum of the diffraction pattern of one matches the minimum the diffraction pattern of the other
Based on this principle we must find the angle of the first minimum of the diffraction expression
a sin θ= m λ
The first minimum occurs for m = 1
sin θ = λ / a
Now let's use trigonometry the object is a distance L = 0.205 m
tan θ = y / L
Since the angles are very small, let's approximate
tan θ = sin θ/cos θ = sin θ
sin θ = y / L
We substitute in the diffraction equation
y / L = λ / a
y = λ L / a
Let's calculate
y = 550 10⁻⁹ 0.205 / 2.15 10⁻³
y = 52.44 10⁻⁶ m
B. 1520 is the difference between their weights.
