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.)

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.

Two charged balls are 10 cm apart. One is positively charged, and the other is negatively charged.

asambeis [7]

Answer:Explanation: The field lines of the electric charges extend from the positive to negative side charge. ... The force between the two charged balls is attractive. It is directly proportional to the product of their charges and inversely proportional to the magnitude of the distance between them.

Explanation:

hope this helps
