Explanation:
The given data is as follows.
= 57 kg, 
= 79 kg
= 6.5 m, 
= (6.5 - 1.9) m = 4.6 m
(a) The sum of torque ends about far end is as follows.
= 0
= 0
T = 828 N
Therefore, 828 N is the tension in the cable closer to the painter.
(b) Now, we will calculate the sum about close ends as follows.
= 0
T= 506 N
Therefore, 506 N is the tension in the cable further from the painter.
The answer for this would be A. since power is Joules/seconds and energy is rated in Joules
The best answer would be the second option B) because that is NOT part of the Kinetic Molecular Theory.
The change in electric potential energy will be converted to kinetic energy; thus:
K.E = 5.3 x 10⁻¹⁰ - 3.1 x 10⁻¹⁰
K.E = 2.2 x 10⁻¹⁰ Joules
Option D is correct.
The dummy's acceleration is 11 m/s^2
(also known as 11 meters per sec. per sec.)
a = F/m
= 825 N/75 kg
= 11 m/s^2
