What is an equilibrant?

<span>The equilibrant, also known as the counterbalancer in a force system, is an equal but opposite force that produces equilibrium. It acts against the resultant force to keep a body motionless. Suppose we have a 20kg mass on one end of a swing and nothing on the other. The swing will be titled unevenly because no force balances the 20kg weight. On the other hand suppose a weight of 40kg rest on the other end. This force doesn't produce equilibrium either because it isn't equal to the 20kg weight; the swing would tilt towards the weight of larger mass. A 20kg mass will balance the system. Hence the force which balances other forces, thus bringing an object to equilibrium is the equilbrant.</span>

D an object that has no netforce acting on it. Because it may be an object is at rest or at a constant velocity
Hope this helps

A bowl contains 4 red balls and 2 green balls. Two balls are selected simultanesouly and at random. What is the conditional prob

AlladinOne [14]

Answer:0.6

Explanation:

Given

Bowl contains 4 red and 2 Green balls

Probability of selecting two red balls given atleast one of the ball is red + Probability of selecting two red balls given that no ball is red =1

Probability of selecting two red balls given that no ball is red $=\frac{Probability \ of\ selecting\ two\ red\ balls\ out\ of\ 4\ balls}{probability\ of\ selecting\ 2\ balls\ out\ of\ 6 balls}$

$P=\frac{^{4}C_2}{^{6}C_2}$

$P=\frac{2}{5}$

Required Probability $=1-\frac{2}{5}=\frac{3}{5}$

A cat dozes on a stationary merry-go-round, at a radius of 5.7 m from the center of the ride. Then the operator turns on the rid

tatyana61 [14]

Answer:

0.76

Explanation:

we are given:

radius (r) =5.7 m

speed (s) = 1 revolution in 5.5 seconds

acceleration due to gravity (g) = 9.8 m/s^{2}

coefficient of friction (Uk) = ?

we can get the minimum coefficient of friction from the equation below

centrifugal force = frictional force

m x r x ω^{2} = Uk x m x g

r x ω^{2} = Uk x g

Uk = $\frac{ r x ω^{2} }{g}$

where ω (angular velocity) = $\frac{2π}{time}$

= $\frac{2π }{5.5}$ = 1.14

Uk = $\frac{ 5.7 x 1.14^{2} }{9.8}$ = 0.76

A child with mass of 25 kg gets into a toy car with mass of 80 kg on a playground, causing it to sink on its springs (with effec

Bess [88]

Answer:

The frequency of the oscillation is 0.9Hz

Explanation:

This problem bothers on simple harmonic motion of a spring

Given data

Mass of the child m= 25kg

Spring constant k=791 N/m

Amplitude a= 31cm

But the period of the motion as a result of the adults sholve is expressed as

T=2π√m/k

T=2*3.142√25/791

T=6.284√0.031

T=6.284*0.176

T=1.11 sec

But frequency F=1/T

F=1/1.11

F=0.9Hz
