Fran hangs three balloons from strings. She gives the first balloon a positive charge. She gives the second balloon a negative c
fgiga [73]

Explanation: We are given three balloon carrying different charges: One having positive charge, one having negative charge and one having no charge.

When we bring positive rod near these three balloons, all of them behave differently.

According to the Coulomb's Law:

Like charges repel each other and unlike charges attract each other.

  • When we bring positive rod towards the balloon having positive charge, the balloon will move away from the rod, because like charges repel each other.
  • When we bring positive rod near negative balloon, the balloon will be attracted to the rod because unlike charges attract each other.
  • But, when we bring positive rod towards the balloon having no charge, the charges will be induced in the balloon. Although the balloon is neutral in nature but it will still carry some +ve or -ve charges. So, when the positive rod is bought near neutral ball, the negative side of the balloon will get attracted towards the rod and positive side will be repelled. From this, we say that the rod has induced some charges in the balloon.

A single serving bag of snack chips contains 65.0 Cal. Assuming that all of the energy from eating these chips goes toward keepi
AveGali [126]

Answer:

= 62.1 hours

Explanation:

Energy provide by the serving is 65 cal

= 65 cal  × 4.184 Kj = 271.96 kJ

271.96 KJ = 271960 J

Energy required for 1minute of energy

= 73 x 1

= 73 J/min

So, 271960 joules will be required for 271960 heart beat

Minutes = 271960 / 73

= 3593.94 minutes  

Time in hours = 3725.429 / 60

= 62.1 hours

How much power is used if a force of 54 newtons is used to pull a wagon a distance of 10 meters in 6 seconds? 3,240 W 90 W 32.4
timama [110]
Power is defined in a mathematical expression as P = F x v where F is in N and v is in m/s. From the given equation, the v = d/t which is v = 10/ 6, then substituting the answer to the power formula W = 54 N (10/6 m/s) = 90 Watts.
