You are watching: The distance between two near field communication (nfc) devices is` limited to about ________.
A hot-air balloon the diameter 12 mm rises vertically at a consistent speed the 15 m/sm/s. A passenger accidentally fall his camera
To resolve this difficulty we will use the straight motion kinematic equations. V the information provided we will calculate the moment it takes for the object to fall. From the time, given that the ascent rate is constant, we will take the reference distance and also calculate the street traveled if the object hit the ground, the is,
Then the total distance traveled would certainly be
Therefore the railing will be at a elevation of 77.7m when it has touched the ground
Large, low push systems transferring cool wait collide v the warmth winds close to the tropical ocean"s surface, pushing huge amounts that water vapor into the top elevations. This heightened circulation of warm air causes the upper level wind speed to increase and storms to develop.
The frequency the the middle B keep in mind on a piano is 493.88 Hz. What is the wavelength that this keep in mind in centimeters? The rate of sou
v = f × lambda
lambda = v/f
v = 343.06m/s to cm/s
343.06 × 100
f = 493.88 Hz
lambda = (34306/493.88) cm/s÷Hz
lambda = 69.46cm
The segment ~ above the left has actually diameter 1.6 mm, and each that the segment on the right has diameter 0.4 mm. I think the blood can be
The flow entering the very first segment will certainly be the same as the circulation exiting the 2nd segment, and in both cases it will certainly be equal to the velocity multiply by the area the the segment. If
You can additionally calculate the transversal area of every segment, because blood vessels are cylinders and also you know each segment"s diameter. The formula to calculation this is:
Replacing d for each segment friend have:
Now, replacing these values on (1), you have:
This method that velocity in the 2nd segment is 15.4 time the velocity in i m sorry blood gotten in the very first segment.
