Answer:
is weaker than the electromagnetic force
Explanation:
The weak force or weak nuclear force acts between elementary particles.
Weak nuclear force is important in the reaction speed of some nuclear reactions that occur in stars. It is also present at the origin of volcanic explosions.
The weak force is a short-range force, less than a billionth of a millimeter: 10-13mm. At a greater distance, the intensity of this force is already negligible.
If the weak force had a value of 1,
the electromagnetic force would have a value of 1,000
and the strong force would be worth 100,000,000,000
Although it is vastly weaker than the other two nuclear forces, the weak force is important in that it enables the Sun and stars to produce light and energy.
The weak force causes a type of radioactive decay called "beta decay." An example of beta decay is the decay of the neutron when it becomes 1 proton + 1 electron + 1 neutrino
Answer:
Explanation:
Pinhole camera is a simple camera. It does not have a lens. The light passes from a hole and an inverted image is formed on the opposite side of the box.
Answer:
(a) A = 0.700m
(b) k = 80.6N/m
(c) x = -0.699m
(d) x = -0.350m
(e) t = 0.168s
Explanation:
Given the equation of motion for the spring
X = 0.700cos(12.0t), m = 0.56kg
(a) A = amplitude = 0.700m
(b) The angular velocity ω = 12rad/s
ω = √(k/m)
ω² = k/m
k = m×ω² = 0.56×12² = 80.6N/m
Spring constant k = 80.6N/m
(c) T = 2π/ω = 2π/12
T = 0.524s
At t = T/2 = 0.524/2 = 0.262s
So x = 0.700cos(12×0.262) = –0.699m
(d) At t = 2/3×T = 2×0.524/3 = 0. 349s
x = 0.700cos(12×0.349) = –0.350m
(e) to find t at x = -0.300m
–0.300 = 0.700cos(12t)
–0.300/0.700 = cos(12t)
cos(12t) = –0.429
12t = cos-¹(-0.429)
12t = 2.01
t = 2.01/12
t = 0.168s
Answer:
Amplitude
Explanation:
The amplitude is maximum height a wave is measured from its rest position.
