Answer:
400.7886829 rad/s
Explanation:
First we have to turn our 0.35 rev/s into rad/s using the equation
(Xrev/s)*2pi=Xrad/s we can plug in .35*2pi=.7pi rad/s
Now we can us the equation m_1*v_1*r_1^2=m_1*v_2*r_2^2 we can plug in the given. Because the mass remains the same we can cross it off of both sides giving us just: v_1*r_1^2=v_2*r_2^2
(.7pi)*(.54)^2=(v_2)*(.04)^2
(.20412pi)=(v_2)*(.0016) [.20412pi=.6412618925]
then using division on both sides we get
(.6412618925/.0016)=v_2=400.79rad/s(This answer is rounded to the nearest hundreth)

they're both properties of water. both involve the "sticking" property of H2O .</span><span>
cohesion is "sticking" together (water sticking to water) and adhesios is water</span><span>

"sticking" to something else. They are both important to life processes.
<span>In chemistry, adhesion refers
to the tendency of unlike molecules to bond with one another, while
cohesion refers to the attractive force between molecules of the same
type. Surface tension, which is an essential property of water, illustrates the relationship between adhesion and cohesion.</span>
Answer:
b
Explanation:because endothermic contains heat so cookies need heat
Answer: its b because as soon as you go far away from light it get red and dents
Explanation:
Explanation:
The primary reason for this is efficiency. In most applications, a lower resistance means less power is converted to heat and lost to the surrounding environment and more of the supplied power gets to its intended destination.
