Answer:
By energy efficient, if you mean LED, no the lamp will not flow like normal. If the bulb is still an incandescent but slightly lower wattage, it will take a little longer to get going. Lava lamps require heat and light for the effect to work.
Answer:
48 m
Explanation:
An object is said to be moving in uniform motion if its velocity is constant.
For an object in uniform motion, its average speed is given by the equation:
![v=\frac{d}{t}](https://tex.z-dn.net/?f=v%3D%5Cfrac%7Bd%7D%7Bt%7D)
where
v is the average speed
d is the distance covered
t is the time taken
For the object in this problem, we have:
v = 6.0 m/s is the average speed
t = 8.0 s is the time taken
Solving for d, we find the distance traveled:
![d=vt=(6.0)(8.0)=48 m](https://tex.z-dn.net/?f=d%3Dvt%3D%286.0%29%288.0%29%3D48%20m)
Answer:
0.00461031264 m/s
Explanation:
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
M = Mass of the Earth = 6 × 10²⁴ kg
r = Distance between Earth and Sun = ![1.5\times 10^{11}\ m](https://tex.z-dn.net/?f=1.5%5Ctimes%2010%5E%7B11%7D%5C%20m)
t = Time taken = 3 days
Acceleration is given by
![a=\dfrac{GM}{r^2}\\\Rightarrow a=\dfrac{6.67\times 10^{-11}\times 6\times 10^{24}}{(1.5\times 10^{11})^2}\\\Rightarrow a=1.77867\times 10^{-8}\ m/s^2](https://tex.z-dn.net/?f=a%3D%5Cdfrac%7BGM%7D%7Br%5E2%7D%5C%5C%5CRightarrow%20a%3D%5Cdfrac%7B6.67%5Ctimes%2010%5E%7B-11%7D%5Ctimes%206%5Ctimes%2010%5E%7B24%7D%7D%7B%281.5%5Ctimes%2010%5E%7B11%7D%29%5E2%7D%5C%5C%5CRightarrow%20a%3D1.77867%5Ctimes%2010%5E%7B-8%7D%5C%20m%2Fs%5E2)
Velocity of the star
![v=u+at\\\Rightarrow v=0+1.77867\times 10^{-8}\times 3\times 24\times 60\times 60\\\Rightarrow v=0.00461031264\ m/s](https://tex.z-dn.net/?f=v%3Du%2Bat%5C%5C%5CRightarrow%20v%3D0%2B1.77867%5Ctimes%2010%5E%7B-8%7D%5Ctimes%203%5Ctimes%2024%5Ctimes%2060%5Ctimes%2060%5C%5C%5CRightarrow%20v%3D0.00461031264%5C%20m%2Fs)
The Sun's speed will be 0.00461031264 m/s
No additional force is required because it's already going downhill
