Action and reaction are equal and opposite (Newton’s 3rd Law) so a deadly force must create a deadly reaction.
Fc=mv2/r formula of centripetal force will be applied here with radius mass and velocity described in the above question
Answer:
Ok I’m not pretty sure but I think it’s C but look for more answers first before you put C because I don’t want you to get it wrong. :)
Explanation:
#28
Fluid always flow from higher pressure to lower pressure so as we can see the figure liquid is coming out of the spray bottle so it clearly shows that the pressure outside the tube will be lower than the pressure inside the tube.
#29
Momentum is defined as product of mass and its velocity
so here we will have
here we have
so we will have
Use the definition of average acceleration:
<em>a</em> = ∆<em>v</em> / <em>t</em>
If <em>v</em> is the starting speed, then ∆<em>v</em> = 0 - <em>v</em>, so solve for <em>v</em> :
-6.42 m/s² = (0 - <em>v</em>) / (2.85 s)
<em>v</em> = (6.42 m/s²) (2.85 s)
<em>v</em> ≈ 18.3 m/s
