The first one is: head
Second one is: 10 trillion km
bonsoir, je peux vous aider avec les maths laissez-moi comprendre merci
Let:
<span>m- 0.0600Kg </span>
<span>v1- +50.0 m/s </span>
<span>v2- -42 m/s </span>
<span>a) </span>
<span>momentum1 - momentum2 = impulse </span>
<span>p1 - p2 = Ft </span>
<span>m(v1 + v2) = Ft </span>
<span>Ft = 0.54 N-s </span>
<span>b) </span>
<span>Work is traditionally force times distance but an easy way to get through this one is to think logically and keep your units straight: </span>
<span>The racket creates an overall velocity of 90 m/s for the ball: </span>
<span>W=(Ft)*(V) </span>
<span>W=0.54 N-s * 90 m/s </span>
<span>W=48.6 N-m = 48.6 J</span>
The answer is C nucleic acids
Answer:I think the answer is B. The alpha Deacy but not sure
