Answer:
a) 2Hz
b) 0.5seconds
c) 0.34m/s
Explanation:
a) Frequency is defined as the number of oscillations completed by a wave in one second.
If my finger is dipped into a pan of water twice each second, it means that my hand has made 2 oscillations through the water in one second. An oscillation is a to and fro movement of a particle, body or wave through a medium.
Based on the conclusion, the frequency of the waterwaves will be 2Hertz or 2cycles/sec.
2) Period T of a wave is defined as the time taken by a wave to complete one oscillation. It is the reciprocal of the frequency of a wave.
T = 1/F
Given frequency = 2Hertz
T = 1/2
T = 0.5seconds
Period of the water wave is 0.5seconds
c) speed of the wave v is expressed according to the relationship:
velocity = frequency × wavelength
Given:
Frequency = 2Hertz
Wavelength = 0.17m (Since it is the difference between two successive crest or trough of a wave)
Velocity = 2×0.17
Velocity = 0.34m/s
Answer:
m = 0.164 kg
Explanation:
T (period)
k (force/spring constant)
m (mass)
T = 2*Pi*sqrt(m/k)
T/(2*Pi) = sqrt(m)/sqrt(k)
(T/(2*Pi))*sqrt(k) = sqrt(m)
m = ((T/(2*Pi))*sqrt(k))^2
m = 4.5*((1.2/(2*Pi)))^2
m = 0.1641403175
There are several approaches. The most favourable one (in my opinion) is this one:
1. Asking a question
2. Doing a research (how to answer this question)
3. Creating a hypothesis (NOT a thesis!)
4. Experimenting (to prove the hypothesis)
5. Analysing results from the experiment
6. Writing a thesis
Answer:
AAT-CAG-GT
AAT-CGA-GT
Explanation:
Because they are both missing one letter
Sliding and Static.
Would be the right one here.
