Positive and negative charges are attracted to one another. The phenomenon of static electricity requires a separation of positi

ve and negative charges. Laundry in a clothes dryer often becomes charged with static electricity while drying. Which of these best explains why a clothes dryer often generates static electricity? A) Short circuits in the dryer charge the laundry. B) Heat from the dryer charges the air and produces lightning. C) Clothes with metal pieces conduct electricity in the dryer. D) Electrons are transferred as clothes rub against each other in the dryer.

D is correct.

This is why clothes often "cling" after getting out of the dryer.

A tennis ball rolls off the edge of a table. the table is 0.55m tall and the tennis ball lands 0.12m away from the table.
k0ka [10]

Answer:

v = 0.363 m/s

Explanation:

Given that,

The table is 0.55m tall and the tennis ball lands 0.12m away from the table.

Here, u = 0 (at rest) for initial vertical velocity as it rolls off the edge of a table.

Let t is the time to fall from the vertical height. So,

h=ut+\dfrac{1}{2}at^2\\\\t=\sqrt{\dfrac{2h}{g}} \\\\t=\sqrt{\dfrac{2\times 0.55}{9.8}} \\\\t=0.33\ s

It can be assumed to find the initial horizontal velocity of the tennis ball. It can be given by :

v_x=\dfrac{x}{t}\\\\v_x=\dfrac{0.12}{0.33}\\\\v_x=0.363\ m/s

Hence, the initial horizontal velocity is 0.363 m/s.

Does hot water always freeze faster than cold water
svp [43]
Yes because there is more temperature to cover in terms of hot water turning into cold and then solid water, and therefore hot water cools down faster, whereas cold water will take more time to become solid.
