Waxing is when the moon gains more light that is visible to us from the sun and will eventually become a full moon which is when it looks like a pie and waining happens after the waxing process and eventually from our prospective will look like a banana
The clam in free fall was dropped from 44.1 m above the ground.
Explanation:
To find how high the clam was dropped from, we just need to analyze its vertical motion.
Its vertical motion is a free-fall motion: this means that the only force acting on the clam is gravity, so it falls down at a constant acceleration of
![g=9.8 m/s^2](https://tex.z-dn.net/?f=g%3D9.8%20m%2Fs%5E2)
known as the acceleration of gravity.
We can find the vertical distance covered by the clam by using the following suvat equation:
![s=ut+\frac{1}{2}at^2](https://tex.z-dn.net/?f=s%3Dut%2B%5Cfrac%7B1%7D%7B2%7Dat%5E2)
where
u = 0 is the initial vertical velocity of the clam (zero since the seagull is flying horizontally)
t = 3.0 s is the time taken for the fall
is the acceleration
Solving for s, we find
![s=0+\frac{1}{2}(9.8)(3.0)^2=44.1 m](https://tex.z-dn.net/?f=s%3D0%2B%5Cfrac%7B1%7D%7B2%7D%289.8%29%283.0%29%5E2%3D44.1%20m)

Answer:
206.85 kPa
Explanation:
Maximum pressure, p = 30 psi
To convert the pressure of psi units into Pa we use the following
1 psi = 6894.76 Pa
1 kPa = 1000 Pa
So, 1 psi = 6.895 kPa
So,
30 psi = 30 x 6.895 kPa = 206.85 kPa
Thus, 30 psi is equal to 206.85 kPa
Answer:
Acceleration is zero
Explanation:
if the acceleration is zero, then the velocity-time graph is a horizontal line (i.e., the slope is zero). If the acceleration is positive, then the line is an upward sloping line (i.e., the slope is positive).
Answer:
The electromotive force is the voltage measured across the cell terminals when "NO" current is being drawn. That is why electromotive forces are used in Wheatstone Bridges which measure the resistance of an external object.
Just measuring the voltage across a cell does not give one the true EMF because current drawn from the cell will cause a reduction of voltage of I * R where R is the internal resistance of the cell.
