<span>Since there are four tires, the total area is 0.018m^2 * 4 = 0.072m^2. Pressure = force / Area => 180*10^3 = Force/0.072 => Force= 12960 N. Then we plug the result for Force into Force =Mass* Acceleration => 12960 = mass*9.8m/s^2 => Mass = 1322.4kg. (Note that 9.8m/s^2 is the gravitational constant for acceleration.)</span>

The wave height is equal to twice the _____.wave period wave height wave amplitude wave velocity wavelength
Archy [21]

The wave height is equal to twice the amplitude of the wave.

The wave height of a wave of given wave with amplitude, period and wavelength is equal to twice the amplitude of the wave.

The amplitude of a wave is the maximum displacement of the wave, starting from the zero position of the wave. The wave height measures twice the maximum displacement of the wave.

Thus, we can conclude that the wave height is equal to twice the amplitude of the wave.

Briefly explain why ferritic and austenitic stainless steels are not heat-treatable.
loris [4]

Answer and Explanation:

Ferritic and Austenitic stainless steels are not heat treatable since the term "heat treatable" means that Martensite may be made to form in a relatively easy way after it has quenched the Austenite from an increased temperature.

When a certain rubber band is stretched a distance x, it exerts a restoring force of magnitude f = ax, where a is a constant. th
Veseljchak [2.6K]
Given:
F = ax
where
x = distance by which the rubber band is stretched
a =  constant

The work done in stretching the rubber band from x = 0 to x = L is
W=\int_{0}^{L} Fdx = \int_{0}^{L}ax \, dx = \frac{a}{2}  [x^{2} ]_{0}^{L} =  \frac{aL^{2}}{2}

Answer:  \frac{aL^{2}}{2}
