1.) The properties of a wave are the following.
a) <span><span>Amplitude - the height of the wave, measured in meters.
</span><span>b) Wavelength - the distance between adjacent crests, measured in meters.
</span><span>c) Period - the time it takes for one complete wave to pass a given point, measured in seconds.
</span><span>d) Frequency - the number of complete waves that pass a point in one second, measured in inverse seconds, or Hertz (Hz).
</span><span>e) Speed - the horizontal speed of a point on a wave as it propagates, measured in meters / second.
Among these properties, PERIOD and SPEED changes if the wave changes media. The others remain the same.
2. Speed = Wavelength * Frequency
Wavelength and Frequency are independent from each other. But you can use the given formula and assume values to check the reaction of one from another.
3. Energy of a wave is based on its amplitude. High amplitude means high energy and vice versa. To increase the energy of a wave, the amplitude must be increased. Another way of increasing the energy of a wave is using elastic medium. </span></span>
<span>If the temperature increases in a sample of gas at constant volume, then its pressure increases. The increase in temperature makes the molecule hit the walls of the container faster. The correct option among all the options that are given in the question is the third option or option "c". I hope the answer helps you.</span>
The acceleration of the SRB and main engine during the first 2.0 minutes of flight is 52.16 m/s².
The given parameters;
- <em>initial velocity of the engine, u = 1341 m/s</em>
- <em>final velocity of the engine, v = 7600 m/s</em>
- <em>time of motion, t = 2 minutes = 2 x 60 s = 120 s</em>
The acceleration of the SRB and main engine is calculated as follows;
Thus, the acceleration of the SRB and main engine during the first 2.0 minutes of flight is 52.16 m/s².

One can simply find the frictional force acting on an object using this equation:
(Ffrict<span> = μ•F</span>norm<span>)
</span>
The process of determining the value of the individual forces acting upon an object involve an application of Newton's second law (Fnet=m•a) and an application of the meaning of the net force. If mass (m) and acceleration (a) are known, then the net force (Fnet) can be determined by use of the equation.
<span>Fnet = m • a</span>
If the numerical value for the net force and the direction of the net force is known, then the value of all individual forces can be determined.
Answer:
False.
Explanation:
Up regulation involves the increase of receptors and it makes the cells more sensitive to the hormones.It's the down regulation that involves the loss of receptors and prevents the target cells from overreacting to persistently high hormone levels.
