given pressure
18N/cm^2
and <em>Force</em> = 9000N
making <em>area</em> the subject in the relation above.
substitute their values into the equation
Answer:
10 N
Explanation:
Work done is the dot product of the force magnitude with distance and cosine of the angle betweenthem.
Equation to use: W=|F|*|d|*cosθ
Your unknown is the force F; You have one equation, oneunknown.
40j=(F)*(4m)*cos(0)
F=40j/4m
F=10N
Answer: the frequency observed will be 1269.45hz
Explanation: according to the doppler effect,
Apparent frequency f' = (c/(c+u))*f
f = real freq of sound of moving sound source
c = speed of sound in air
u = speed of moving sound source
f' = (343/(343+33.6))*1395
f' = 1269.45hz
Answer:
Mistakes, chaos theory.
Explanation:
Weather forecast refers to the application of technology and science in predicting what the condition's of an atmosphere would be at a particular time in a given location. Keyword here is "Predicting."
To accurately "predict" the weather, observation data needs to be collected from weather stations across the world. The data collected from the stations are too complex such that they can only be processed by supercomputers.
It is important to note that supercomputers used to predict weather are liable to make mistakes because the enormous challenge of weather forecasting is more than their capabilities.
In addition, there is a concept known as chaos theory. It explains how very small changes in initial weather conditions can change the final results. No thanks to chaos, meteorologists would not be able to predict weather accurately.
This is the reason why the world still suffers from the incidence of surprise rain, storms and other weather events that could be devastating.
Answer:
In order to convert density to grams, you have to put the mass on one side of the equation, and the density and the volume on the other. Therefore, d * v = m. Multiply the density by the volume. Using the example in step 1, you would multiply 2 g/mL by 4mL.
