Answer:
Explanation:
Stocks give you partial ownership in a corporation, while bonds are a loan from you to a company or government. The biggest difference between them is how they generate profit: stocks must appreciate in value and be sold later on the stock market, while most bonds pay fixed interest over time.
(a) Amplitude=1.5 m
Amplitude is the maximum distance from the mean (zero disturbance) position.Here amplitude= 1.5 m
(b) wavelength= 2 m
Wavelength is the length of one complete wave or distance traveled by a wave in a time equal to Time Period. Here wavelength= 2 m
(c) Frequency=7.5 Hz
using equation for wave velocity V= f λ
15= f (2)
f=7.5 Hz
so frequency=7.5 Hz
(d) Time period= 0.133 s
Time period= T= 1/f
T= 1/7.5
T=0.133 s
so time period=0.133 s
From the questions very confusing but quite interesting
solution:
2÷9×9=2 that means the amount is two naira in my country
Answer:
10 m/s
Explanation:
Use the kinetic energy formula:
KE=(1/2)mv^2
I always remember it as Kevin is half-mad, and very square.
25J = (1/2)*0.5kg*(v^2)
50J = 0.5kg*(v^2)
100J = v^2
v = 10 m/s
Check it:
KE = (1/2)*0.5*(10^2)
KE = 25J
yep, it's right!
