Physical science explains the physical world and not supernatural events and an idea is considered true by science if it can be observed, explained and reproduced by others.

<h3>What is physical science?</h3>

Physical science is a systematic study of the of the physical world and phenomena based on observation and experiments.

The scientific method involves:

  • observation and questions
  • hypothesis
  • experiments
  • results and further experiments
  • theories and laws

Science explains the physical world and not supernatural events.

Science studies physical phenomena such as the stars, the planets, living things, etc.

Science do not study about angels or demons or supernatural events.

An idea is considered true by science if it can be observed, explained and reproduced by others.

Calculate the coefficient of friction of a 12kg object that has a force of friction of 3N
postnew [5]

Answer:

0.026

Explanation:

The force of friction acts in the direction perpendicular to the norm force of the surface on which the object rests, induced by gravity. The magnitude of the friction force is

(Friction) = (mass) x (gravitational acceleration g) x (coefficient of friction)

from which the coefficient of friction can be determined:

(coefficient of friction) = (Friction) / ((mass)x(g)) = 3 N / (12 kg * 9.8 m/s^2) = 0.026

A Micro –Hydro turbine generator rotor is accelerating uniformly from an angular velocity of 610 rpm to its operating angular ve
solniwko [45]

Answer:

The rotor's angular velocity is 82.73rad/s

Explanation:

It is a curvilinear movement of a constant radius. If there is uniform angular acceleration, then it is a circular motion with constant acceleration, whose equations are analogous to that of the translational motion.

Calculating the initial velocity of the rotor, V1 in rad/s

V1 = 610rev/minute × 6.28 × 1miute/60secs

V1 = 63.85rad/s

Using kinematic equation to calculate the final velocity of the rotor

Given:

Angular acceleration = 5.9rad/s^2

Time,t= 3.2seconds

V2 = V1 + a × t

V2 = 63.85 + (5.9)× (3.2)

V2 = 63.85 + 18.88

V2 = 82.73rads/s
