Answer is A, constructive interference
The efficiency of the bicycle is 20% because 200 out 100 is 2.and ,convert 1000 j out 100 that equal to 10 but,then multiply 2×10 that equal to 20%
It’s A I think, hopefully that’s right
Answer:
8.975 m/
Explanation:
Travel starting velocity (u) = 34.8 m/s
Achieved (final) velocity = 214.3 m/s
Travelling time(t) = 20 s
we know that, v =u +at
; where v= final velocity
u=start velocity
a=acceleration
t=time
Therefore,
His acceleration, a = (v-u)/t
=(214.3-34.8)/20
= 8.975 m/
Answer:
Face - off
Explanation:
Face - off is a term used in ice hockey to start periods of play and also to restart the play/action after a previous stoppage.
This face - off involves two opposing players from the 2 opposing teams standing opposite each other at an approximate distance of one sticks blade with the game official dropping the puck between them. Thereafter, two players will then to try to gain possession of the puck.
