Since Astronaut and wrench system is isolated in the space and there is no external force on it
So here momentum of the system will remain conserved
so here we can say
initially both are at rest
so here plug in all values
so here the astronaut will move in opposite direction and its speed will be equal to 0.20 m/s
1 atom of Mg(Magnesium) and 2 atoms of Br(Bromine)
Explanation:
50 meters north in 10 seconds.
speed = distance ÷ time = 50 meters ÷ 10 seconds = 5m/s
70 mph
= 70 * 1600 m/h
= <span>112000 m/h
-> 112000 m/h
= 112000 /3600 m/s
= 31.111... m/s
= <u>31 m/s (2s.f)</u></span>
Answer:
Wave height is the vertical distance between the crest (peak) and the trough of a wave. Some other definitions: Still-Water Line is the level of the lake surface if it were perfectly calm and flat. Crest is the highest point on the wave above the still-water line.
