Answer:

Person’s mass M = 83.67 kg (Approx.)

Explanation:

Given:

Gravitational potential energy = 164,000 J

Height = 200 m

Find:

Person’s mass M

Computation:

Gravitational acceleration g = 9.8 m/s²

Gravitational potential energy = mgh

164,000 = (m)(9.8)(200)

Person’s mass M = 83.67 kg (Approx.)

Please help me guys never mind the calculations ​

The shape is connected in parallel so;

5.1) Ans;

\frac{1}{R}  =  \frac{1}{R1} +  \frac{1}{R2}   \\  \frac{1}{R}  =  \frac{1}{2}  +  \frac{1}{3}  \\  \frac{1}{R}  =  \frac{3 + 2}{6}  =  \frac{5}{6}  \\ R =  \frac{6}{5}  = 1.2 \:  \: ohm

5.2) Ans;

\frac{1}{R}  =  \frac{1}{R1} +  \frac{1}{R2}   \\  \frac{1}{R}  =  \frac{1}{8}  +  \frac{1}{10}  \\  \frac{1}{R}  =  \frac{5 + 4}{40}  =  \frac{9}{40}  \\ R =  \frac{40}{9}  = 4.4 \:  \: ohm

I hope I helped you^_^

Explain the Kinetic Theory of Matter<br> and use an example from everyday life
abruzzese [7]

Answer:

The Kinetic Theory of Matter or KTM as i will call it, states that every object is made of many many small particles (humans are made of sextillions of atoms), and that they are constantly moving and bumping each other. The degree to which the particles move is determined by the amount of energy they have and their relationship to other particles.

An example would be Brownian Motion- the random movement of dust particles because of collisions with "air" molecules and how gases behave i.e. Boyle's, Charles', and Gay-Lussac's Laws.
