You just told us that Weight = (mass) x (gravity),
and that mass=10kg and gravity = 9.8 m/s².
All we need to do is write those numbers in place of the letters.
Weight = (10 kg) x (9.8 m/s²) = <em>98 newtons</em>.
Answer:
Well I don't think there is a specific answer for that, but a lot of under the age children do drink and smoke,because these days,their parents either don't care, and some just don't know about it. Many kids drink and smoke these days and I don't think there is a on point percentage.
Explanation: Hope this helps and have a good day!!!
Newtons first law - Objects in the car at rest (The human) will remain at rest unless affected by an unbalanced force. Well the unbalanced force would be the crash and this would set the human in motion and they would ether fly out the car if not wearing a seat belt or if wearing one they would get bad whip lash
Newtons second law - With more mass requires more force, so since the human is pretty light or even if heavy in a big crash there will be so much more from it that this will send the human flying.
Newtons 3rd law - Objects A puts force onto objects b and object b excretes the same amount of force back onto object a, so in a crash the human would hit the car hard and the car would excrete the same amount of force back on the human which would really damage him/her
Answer:
C Don't worry if you thought it was D. I almost answered that.
Explanation:
Remark
You can get this just by learning the vocabulary.
Efficiency = Work Out / Work In * 100%
Work in = 30J That's you swinging the hammer.
Work out = 10 J That's how much of the hammer's work gets to the nail.
Efficiency = (10/30)*100
Efficiency = 1/3 * 100
Efficiency = 33%
What impact ? Is there more to this question so I can help answer ?
