Answer:
μ = 0.724
Explanation:
maximum acceleration for SHM
a = ω²A
ω = 2πf
a = 4π²f²A
a = 4π²(1.50)²(0.080) = 7.106... m/s²
μ = F/N = ma/mg = a/g = 7.106/9.81 = 0.7243...
I'm cynical that a block can be cynical. Wassa madder, doesn't trust anyone?
I think the events are already chronologically arranged correctly. It always have to start with the simplest elements, the hydrogen and helium. In fact, these are the elements that compose the stars. The nuclear fusion of hydrogen atoms to helium is what gives the stars and the sun their energy. So, this is followed by letter b, which is the formation of stars. Then, when these stars explode a stated in c, they produce even heavier elements. As a result, this big bang theory tells us that the universe is expanding because of this 'explosion'. In the end, it led to the formation of the sun, the planets and the universe. <em>Thus, the arrangement is: a, b, c and d.</em>
Answer:
Fusion
Fission
Explanation:
The first problem describes a nuclear fusion process. In this process;
- small atomic nuclei combines to form a larger one.
- it is accompanied by a large release of energy
- this energy provides the needed temperature to set up another light nuclei to fuse.
The second problem describes nuclear fission,
- a heavy nuclide is bombarded with a neutron.
- the product formed becomes unstable and subsequently breaks down.
- This leads to a series of chain reactions until stability is attained.
Answer:
(a) 
(b) 
Explanation:
Given data
Solution
For Part (a)
As the velocity component in direction of y is given by:
The maximum displacement is given by:
For Part (b)
To reach y=46cm =0.46m apply:
Light travels in waves, and light travels at about 3.0x10^8 m/s. and you call that this the 'speed of light' so your answer possible could be
A. It travels at the speed of light.
I might be wrong so double check.
