using trigonometric relation
Answer: 0.9
Explanation:
For an inclined surface the coefficient of friction (n) is the ratio of the moving force (Fm) to the normal reaction (R) acting on the body.
n = Fm/R
Fm = WSintheta = mgsintheta
R = Wcostheta = mgcostheta
n = Wsintheta/Wcostheta
n = sintheta/costheta
n = tan theta
n = tan 42°
n = 0.9
Therefore, minimum coefficient of static friction between the vehicle’s tires and the road is 0.9
<span>The elements of the periodic table are classified into three categories: inert gases, nonmetals and metals. Generally, inert gases do not readily gain nor lose electrons, while nonmetals are more likely to acquire electrons. Metals contain low ionization energies, which refer to the amount of energy required to free or remove an electron. These elements also have low electron affinities, or the attractive forces between an incoming electron and the nucleus of an atom. The lower the ionization energies and electron affinities of an atom are, the greater the tendency to lose electrons.</span>
Answer:
60 cycles
Explanation:
The first thing we must do to solve the problem is to find how many cycles are presented in 1cm by multiplying the frequency by the base time of the
K=time base=2ms/cm=2x10-3s/cm
f=frecuency=3000s^-1
N=fk
N=(3000)(2x10^-3)=6cycles/cm
Ntot=6x10=60cycles
