Describe that a scientific law is a description of a specific relationship under given conditions. Describe that scientific laws are developed from large amounts of experimental observations that result in the same outcome.
Answer:
a. an increase in the mass on the spring.
Explanation:
T = 2π/ω = 2π/√(k/m) = 2π√(m/k)
2π is a constant
as m is in the numerator, increasing mass will increase the period.
43 years old is the life expectancy
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:
The wavelength of the interfering waves is 3.14 meters.
Explanation:
Given that,
The equation of standing wave that is formed by interfering two harmonic waves (travelling opposite direction) is given by :
........(1)
The general equation of standing wave is given by :
..............(2)
On comparing equation (1) and (2), we get :
k = 2
We know that,
So, the wavelength of the interfering wave is 3.14 meters. Hence, this is the required solution.
