Answer:
read a pleasant story to him Because if you threaten him meaning abusing him then you could go to jail for that if you read him a pleasant story to him then he will go to bed faster if you play an activity game he'll stay up longer and if you watch an exciting TV show he'll stay up longer too soon you just want him to go to bed sleep peacefully and that's why you read him a pleasant story So yeah my answer is read a pleasant story to him so he can go to bed and not be threatened or play an activity game or watch an exciting TV show if you want them to go to sleep That is why I put read a pleasant story to him
Your question seems to be incorrect. Please check below:
What force must the deltoid muscle provide to keep the arm in this position? By what factor does this force exceed the weight of the arm?<span>If you hold your arm outstretched with palm upward, as in (Figure 1) , the force to keep your arm from falling comes from your deltoid muscle. Assume that the arm has mass 4 kg and the distances and angles shown in (Figure 1) .
F=?
F/w= ?
The answer is </span><span>339 N</span><span>
</span>
I think its c sorry if I’m wrong
Answer:
Bottom of the circle.
Explanation:
At the top of the circle the tension and the weight contribute on being the centripetal force, at the middle of the circle only the tension contributes on being the centripetal force (the weight being perpendicular to it), while <u>at the bottom</u> of the circle the tension contributes on being the centripetal force (as always) <em>but the weight against to it</em>, so here is where the tension must be greater to allow the same centripetal force as the other cases, thus here is where the string will break.
Answer:
C. molecules speed up as more thermal energy is added
Explanation:
The molecules will simply speed up as more thermal energy is added to the solid.
Thermal energy is a form of kinetic energy which is set in motion.
- Heat causes kinetic energy build up in a body.
- As the molecules of the solid gains heat, they will continue to increase in thermal energy.
- They are forced to start vibrating about their fixed point.
- Thereafter, when they have enough energy, they break free from the forces holding them.
- Therefore, they move from a state of rest to one with a very high kinetic energy where the molecules moves rapidly.
- This is why a solid will change to liquid and sometimes eventually gas
