Answer:
1.6 penny
Explanation:
= Original volume = 1 gal (Assumed)
= Change in temperature
= Coefficient of volume expansion = ![280\times 10^{-6}\ /^{\circ}](https://tex.z-dn.net/?f=280%5Ctimes%2010%5E%7B-6%7D%5C%20%2F%5E%7B%5Ccirc%7D)
Change in volume is given by
![\Delta_V=\beta V_0\Delta T\\\Rightarrow \Delta_V=280\times 10^{-6}\times 1\times (32-3.3)\\\Rightarrow \Delta_V=0.008036](https://tex.z-dn.net/?f=%5CDelta_V%3D%5Cbeta%20V_0%5CDelta%20T%5C%5C%5CRightarrow%20%5CDelta_V%3D280%5Ctimes%2010%5E%7B-6%7D%5Ctimes%201%5Ctimes%20%2832-3.3%29%5C%5C%5CRightarrow%20%5CDelta_V%3D0.008036)
New volume would be
![1+0.008036=1.008036\ gal](https://tex.z-dn.net/?f=1%2B0.008036%3D1.008036%5C%20gal)
The amount of money earned extra would be
![0.008036\times 2=0.016072\ \$](https://tex.z-dn.net/?f=0.008036%5Ctimes%202%3D0.016072%5C%20%5C%24)
1.6 penny more would be earned if the temperature is 32°C
Using first equation of motion;
vf = vi + at --------------------- (1)
where vf = final velocity
vi = initial velocity
a = acceleration (here it is considered to be gravitational acceleration)
t = time
As
vi = 1.8 m/s
vf = 0 m/s
a = g = -9.8 m/s^2 (negative sign is due to the upward motion of tina)
using equation (1),
0 = 1.8 + (-9.8 * t)
t = 9.8/1.8
t = 0.1836 seconds
but the tina has to travel back to the ground, hence the time taken by tina to be in the air will be
t = 2 * 0.1836
t = 0.367 seconds
The best option for the answer of this question is D) The electric charges move from the energy source through the buzzer and back to the energy source.
Declination is the difference between avtrue geographic north and the compass indicated "north" that is measured in degrees. To describe the earth's magnetic declination one must consider the angle between the true north and the north indicated by a compass.
