A 95 kg clock initially at rest on a horizontal floor

Physics
1 answer:
Nataly [62]3 years ago
4 0

Answer:

You are given that the mass of the clock M is 95 kg.

This is true whether the clock is in motion or not.

Fs is the frictional force required to keep the clock from moving.

Thus Fk = uk W = uk M g      the force required to move clock at constant speed.     (the kinetic frictional force)

uk = 560 N / 931 N = .644   since the weight of the clock is 931 N  (95 * 9.8)

us  is the frictional force requited to start the clock moving

us = static frictional force = 650 / 931 -= .698

Answer:

<em>The new force is 2/3 of the original force</em>

Explanation:

<u>Coulomb's Law </u>

The electrical force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between the two objects.

Written as a formula:

\displaystyle F=k\frac{q_1q_2}{d^2}

Where:

k=9\cdot 10^9\ N.m^2/c^2

q1, q2 = the objects' charge

d= The distance between the objects

Suppose the first charge is doubled (2q1) and the second charge is one-third of the original charge (q2/3). Now the force is:

\displaystyle F'=k\frac{2q_1*q_2/3}{d^2}

Factoring out 2/3:

\displaystyle F'=\frac{2}{3}k\frac{q_1*q_2}{d^2}

Substituting the original force:

F'=\frac{2}{3}F

The new force is 2/3 of the original force

Looking at systems is important in science because
Vikentia [17]

Answer:

systems help identify parts and simplify solutions.

Explanation:

Systems are very important in science because they are made up of many parts and can help simplify solutions better.

A system is made up of several parts that are interacting together as a whole. They are very important in solving scientific problems and looking introspectively into a problem.

The parts that makes up the system are equally important as the whole. Systems are typified by what transpires at the level of their parts. Viewing a problem from a system wide angle helps scientists have better knowledge and can be vital in solving scientific problems.
