Do you guys know how to find out the Wave Speed using frequency and wavelength?

1 answer:

6 0

Given the relationship: v = wavelength times frequency

this should be as simple as multiplying it out :)

for any other variable just rearrange

velocity = lambda x frequency

where lambda is the wavelength

units:

m/s = m x Hz (1/s)

A sample of an unknown substance has a mass of 89.5 g. If 345.2 J of heat are required to heat the substance from 285 K to 305 K

Zinaida [17]

Heat gained in a system can be calculated by multiplying the given mass to the specific heat capacity of the substance and the temperature difference. It is expressed as follows:<span>

Heat = mC(T2-T1)
345.2 = 89.5(C)(305 - 285)
C = 0.1928 </span>J/g•K

Answer:

966 mph

Explanation:

Using as convention:

- East --> positive x-direction

- North --> Positive y-direction

The x- and y- components of the initial velocity of the jet can be written as
