The answer is New York Beach
Variable in science means a fraction,trait or condition
Answer:
Explanation:
The bulbs becomes dimmer because effective resistance of the circuit increases since the resistance of the circuit in series connection involves adding the individual resistance compared to in parallel connection where the effective resistance = 1 / R1 + 1/R2 = R1 R2 / ( R2 + R1). The brightness remains the same because the lightbulbs must be of the same resistance. Also using ohm's law
V = IR
I = V / R
I is inversely proportional to the current in the circuit so as R, effective resistance of the circuit increases, I, current decreases and vice versa

Answer: The kinetic energy of an apple at 100 m of height while falling is 49 J.
Explanation:
Mass of the apple = 0.100 kg
Height at that instant when apple was at verge of falling = 150 m
The sum of the potential energy and kinetic remains constant.
Sum of P.E and K.E energy at height if 150 m
![P.E+K.E=mgh+\frac{1}{2}mv^2](https://tex.z-dn.net/?f=P.E%2BK.E%3Dmgh%2B%5Cfrac%7B1%7D%7B2%7Dmv%5E2)
Kinetic energy is zero at initial position
![=0.100 kg\times 9.8 m/s^2\times 150 m=147 J+0 J=147 J](https://tex.z-dn.net/?f=%3D0.100%20kg%5Ctimes%209.8%20m%2Fs%5E2%5Ctimes%20150%20m%3D147%20J%2B0%20J%3D147%20J)
Sum of P.E and K.E at height if 100 m
![P.E+K.E=mgh'+\frac{1}{2}mv^2](https://tex.z-dn.net/?f=P.E%2BK.E%3Dmgh%27%2B%5Cfrac%7B1%7D%7B2%7Dmv%5E2)
Kinetic energy is not zero during falling of an apple
![=0.100 kg\times 9.8 m/s^2\times 100 m=98 J+K.E.=147 J](https://tex.z-dn.net/?f=%3D0.100%20kg%5Ctimes%209.8%20m%2Fs%5E2%5Ctimes%20100%20m%3D98%20J%2BK.E.%3D147%20J)
K.E = 147 J - 98 J= 49 J
The kinetic energy of an apple at 100 m of height while falling is 49 J.
