So there was originally air in the Ice Cream because they fluff it up like that. When it melts, those are gone.
Answer:
It sticks to the wall due to electrostatics.
Explanation:
When pam rubs a balloon against his hair, and holds it up against the wall, he is basically adding a surplus of electrons which are negative charges to the surface of the balloon.
This motion would make the wall the more positively charged than the balloon. Therefore, when the two charges come in contact with each other, the balloon will stick to the wall because of the rule in electrostatics that opposite charges attract each other.

- The frequency does not change, but the speed does. If that is true, then the wavelength must also change.</span>
We know, d = m/v
d = 968 g/cm3
m = 250 gm
Substitute their values,
968 = 250 / v
v = 250 / 968
v = 0.26 cm3
In short, Your Answer would be Option B
Hope this helps!
Answer:
Explanation:
It is given that initially sphere has different charges and momentarily brought in contact with each other.
When the spheres are touched then charge is equally redistributed among spheres such that now they possess the equal amount of charges.
When they are suspended from the thread their separation increases compared to previous situation because now the value of force increases because of the change in the product of charges.
For example, Suppose initially they possess 15 C and 17 C charge and after redistribution they both possess 16 C of charge.
Product of charges
Final Product of charges
As force depends upon the Product of the charges so there will be more repulsive force.
