1.A) 4.9 m
AL2006 Ace
The instant it was dropped, the ball had zero speed.
After falling for 1 second, its speed was 9.8 m/s straight down (gravity).
Its AVERAGE speed for that 1 second was (1/2) (0 + 9.8) = 4.9 m/s.
Falling for 1 second at an average speed of 4.9 m/s, is covered 4.9 meters.
ANYTHING you drop does that, if air resistance doesn't hold it back.

Answer:
The combined gas equation relates three variables pressure, temperature and volume when the number of moles is constant.
The equation is PV / T = constant. Which is valid for a fixed number of moles of the gas.
You can derive the combined gas equation from the combination of Bolye's law, Charles' law and Gay-Lussac's law, which needs some algebra.
Explanation:
Answer:
The combination of elements most likely to comprise the circuit are resistor, inductor and capacitor
Explanation:
The impedance of an LCR circuit shown as
Z = √R² + (X↓l - X↓c)²
Z = √R² + (2π∨L - 1/2π∨c)²
Variation of Z with respect to υ is shown in the figure.
As υ increases, Z decreases and so the current increases.
At υ = υ↓r
Z is minimum, current is maximum. Beyond
υ = υ↓r
Z increases and so current decreases.
so the combination of circuit elements that is most suitable to comprise
the circuit is R, L and C.

Answer:
The angular velocity is 15.37 rad/s
Solution:
As per the question:
![\theta = 54.6^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%20%3D%2054.6%5E%7B%5Ccirc%7D)
Horizontal distance, x = 30.1 m
Distance of the ball from the rotation axis is its radius, R = 1.15 m
Now,
To calculate the angular velocity:
Linear velocity, v = ![\sqrt{\frac{gx}{sin2\theta}}](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7Bgx%7D%7Bsin2%5Ctheta%7D%7D)
v = ![\sqrt{\frac{9.8\times 30.1}{sin2\times 54.6}}](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B9.8%5Ctimes%2030.1%7D%7Bsin2%5Ctimes%2054.6%7D%7D)
v = ![\sqrt{\frac{9.8\times 30.1}{sin2\times 54.6}}](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B9.8%5Ctimes%2030.1%7D%7Bsin2%5Ctimes%2054.6%7D%7D)
v = ![\sqrt{\frac{294.98}{sin109.2^{\circ}}} = 17.67\ m/s](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B294.98%7D%7Bsin109.2%5E%7B%5Ccirc%7D%7D%7D%20%3D%2017.67%5C%20m%2Fs)
Now,
The angular velocity can be calculated as:
![v = \omega R](https://tex.z-dn.net/?f=v%20%3D%20%5Comega%20R)
Thus
![\omega = \frac{v}{R} = \frac{17.67}{1.15} = 15.37\ rad/s](https://tex.z-dn.net/?f=%5Comega%20%3D%20%5Cfrac%7Bv%7D%7BR%7D%20%3D%20%5Cfrac%7B17.67%7D%7B1.15%7D%20%3D%2015.37%5C%20rad%2Fs)
