Answer:
C. it will not change.
Explanation:
While combing, the rubbing of the comb with the hair, transfer of electron takes place from the hair to the comb and the comb becomes negatively charged. But, this transfer of electron does not make any considerable change in the mass of the hair. This is because the mass of an electron is highly negligible. Now, neglecting the mass of an electron, the transfer of the electrons from the hair to the comb makes charging of the comb, but no loss of mass in the hair. So, the mass of hair will no change.
Answer:
No imageeeeeeeeeeeeeeeeeeeeee
Answer:
Yes you can. The charging current will be the lowest of the two current ratings of device and charger. The charger and the phone have complex internal circuitry that enable this behaviour.
But using a weaker charger for your phone will only lengthen charging time. And using a stronger charger than that the phone will accept doesn't affect charging at all and only wastes money.
Answer:
Incomplete question: "A signal of 20.7 mV is measured at a distance of 29 mm and 15.8 mV is measured at 32.5 mm. Correct the data for background and normalize the data to the maximum value. What is the normalized corrected value at 32.5 mm?"
The normalized corrected value at 32.5 mm is 0.1638
Explanation:
The corrected light measurement at 29 mm is equal to:
20.7 - 5.1 = 15.6 mV
The corrected light measurement at 32.5 mm is equal to:
15.6 - 5.1 = 10.5 mV
To normalize the data to its maximum value means that the maximum value must be calculated and the data must be scaled using that value, as in this case the maximum value is 15.6 mm, then the normalized corrected value at 32.5 mm is equal to:
10.5 * 15.6 = 163.8 = 0.1638
Answer:
v = 100 m/s
Explanation:
Given:
v₀ = 0 m/s
a = 10 m/s²
t = 10 s
Find: v
v = at + v₀
v = (10 m/s²) (10 s) + 0 m/s
v = 100 m/s
