Question

1.Can a small child play with a fat child onthe see-saw?explain how.
2.Two children are sitting on the see-saw,such that they can not swing.What is the net torque in this situation?
3.Does the speed of a ceiling fan go on increasing all the time?
4.Does the ceiling fan satisfy second condition for equilibrium when rotating with uniform speed?

Answer 1

1. Think about it. What would you do?
2. No motion; no torque
3. What do you think? Watch one sometime.
4. Tell me what the "second condition for equilibrium" is first.

Answer 2

blabla blabla i hate physics

Answer 3

Boring physics

Answer 4

yes a fat chld can play with the fat child

Answer 5

No Cz Fat kid will lower the see saw and little small kid.will be lower down..in this way they cannot ppay together on a see saw .

Answer 6

Can a small child play with a fat child on a see saw? explain how?

Answer 7

A small child cannot play with a fat child because their weight is not balanced.

Answer 8

Yes they can by doubling the moment arm on the arm of small child

Answer 9

No they cannot play together because their weight is not equal to play on sea saw their weight must be equal for e.g the weight of one child is 45 kg then the other weight must be 45kg

Answer 10

Yes. A small child can play with a fat child on a see saw, only if they both are at unequal distances from the pivot of the see saw. Such that the small child is farther from the pivot and the fat is closer. Then the see saw would be balanced and hence, they would be able to swing.

Answer 11

If two children are sitting on A see saw such that they cannot swing, then they will be satisfying the second condition of equilibrium, as the see saw has the tendency to rotate (until a limit.) Hence, the net torque will be zero (according to the second condition of equilibrium.)

Answer 12

Yee they can play on a see saw if they are sitting on unequal distance from the pivot

Answer 13

Yes a small child can play with a fat child on a seesaw ,only if both are at unequal distances from the pivot of seesaw such that a fat child should must be closer to the pivot of seesaw and small child should be farther then the seesaw would be balanced &hence they would be able to swing 💯💯

Answer 14

Yes,ofcourse a small child can play with a fat child on seesaw.
As we know that:
Sum of clockwise moments= Sum of anti-clockwise moments of equilibrium.
So,the distance from the pivot of the seasaw should be increased for the small child so that the moment of force or torque is increased.

Answer 15

Yes they can only if both are at unequal distances from pivot.
According to principle of moments sum of clockwise moments=sum of anticlockwise moments for a system or body to be balanced .the fat child has larger weight so he should be near to the pivot (there will be shorter moment arm ) whereas the small child should be further away from seasaw( there will be longer moment arm ). In this way system will be balanced and they can play sea saw . I hope this helps you:)

Answer 16

Yes a small child can play with a fat girl but just when if they both have unequal distance from pivot of see saw

Answer 17

Fabolous
