Answer:
The 8 foot long plank
Explanation: hope this helps :)
Displacement = s = v1t +1/2at2
= 0 * 2.05 +1/2*(4.3)*(2.05^2)
= 0 + 9.04
= 9.04 m
Electrical currents are steady. Static electricity is periodic and only lasts so long.
Let's use Newton's Law of Second Motion: F=ma. When no other direct force is acting on the system, the acceleration is due to the gravity. The modified equation becomes: F = mg. So, yes, you need to take into account the gravitational accelerations in the moon and on Earth.
g,moon = 1.622 m/s²
g,Earth = 9.81 m/s²
The net force is the tension of the string:
F,Earth - F,moon = Tension
Tension = (1/1000 kg)(9.81 m/s²) - (1/1000 kg)(1.622 m/s²)
Tension = 8.188×10⁻³ N
To convert, 1 pound force is equal to 4.45 Newtons:
Tension = 8.188×10⁻³ N * 1 lbf/4.45 N
Tension = 1.84×10⁻³ lbf
It has holes (an electron deficiency).
