Ageologist estimates that a large boulder weighs 7840 n. what should he estimate the mass of this boulder to be? a. 650 kg b. 740 kg c. 780 kg d. 800 kg

7840N = 799.49 kg therefore D is correct

hello questions under analysis B are not complete hence I couldn't provide its answers

1)

AA batteries have more electrochemical composition AAA batteries are smaller AA batteries store more charges when compared with AAA batteries

2) The average expected value is 1000 k ohms

Explanation:

1) The difference between AA and AAA batteries

some of the differences are

AA batteries have more electrochemical composition AAA batteries are smaller AA batteries store more charges when compared with AAA batteries

2) The average expected value is 1000 k ohms

also it is necessary to measure the resistor because the actual value of resistance gotten from measurement is always different from the value obtained from color coding. also note that The last color band indicates the tolerance.

and the resistor given has Gold as its last color band
