Explanation:

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.

The coefficient of friction (fr) is a number that is the ratio of the resistive force of friction (Fr) divided by the normal or perpendicular force (N) pushing the objects together. It is represented by the equation: fr = Fr/N.

Answer:

$\mu=0.185$

Explanation:

From the question we are told that:

Mass $m=17kg$

Force $F=33N$

Velocity $v=1.6m/s$

Distance $d= 9.8m$

Generally the equation for Work done is mathematically given by

$W=\triangle K.E+\triangle P.E$

Where

$\triangle K.E=(F-F_f)*2$

$F_f=F+\frac{\triangle K.E}{d}$

$F_f=33+\frac{0.5*17*1.6^2}{9.8}$

$F_f=30.8N$

Since

$f = \mu*m*g$

$\mu= 30.8/(m*g)$

$\mu= 30.8/(17*9.81)$

$\mu=0.185$

s344n2d4d5 [400]

Answer:

Nitric acid, also known as aqua fortis and spirit of niter, is a highly corrosive mineral acid. The pure compound is colorless, but older samples tend to acquire a yellow cast due to decomposition into oxides of nitrogen and water. Most commercially available nitric acid has a concentration of 68% in water.

Kazeer [188]

Answer:

the electric field strength of this charge is two times the strength of the other charge

Explanation:

Using the relationship between electric field and the charge, which is inversely proportionality. Let the the magnitude of the first charge be Q and the respective electric field be E. It implies that;

E1/E2 = Q2/Q1

E2 = E1 x Q1/Q2

= E x Q/ (Q/2)

= 2E
