Answer:
He is testing for voltage drop (voltage drop test)
Explanation:
Connecting the red lead of a voltmeter to the B+ output to an ac generator and black lead to a battery +ve terminal measures the voltage drop in the circuit when the engine is turned ON and all electrical accessories too.
with this he knows if the alternator is charging the battery.
Answer:
The repulsive electrostatic force between two of the protons is 14.4 N.
Explanation:
Given;
distance between the two protons, r = 4 x 10⁻¹⁵ m
charge of a proton, q = + 1.6 x 10⁻¹⁹ C
The repulsive electrostatic force between two of the protons is calculated by applying Coulomb's law;
Therefore, the repulsive electrostatic force between two of the protons is 14.4 N.
a =12miles
b =10miles
ab =2miles
Explanation:
at first the car is drown out of dealership and went 10 miles east and then 8 miles south
then your friend drives 8 miles west and 6 miles north.
then the distance it flies to get back to dealership is
10²+8 ²=12miles
8²+6²=10miles
12-10= 2 miles
Answer:
Protein molecules
Explanation:
Ribosomes are the cell organelles that are responsible for the synthesis of protein in the cell. Proteins are the fundamental building blocks and help in repair and damage of cell in the body.
Ribosome is a complex which is made up of protein and RNA. Ribosomes can be found floating within the cytoplasm or attached to the endoplasmic reticulum.
Time = (distance) / (speed)
Time = (4.12x10^16 m) / (3 x10^8 m/s)
Time = 1.37 x 10^8 seconds
Divide the seconds by 86,400 to get days. Then divide the days by 365 to get years.
Time = about 4.35 years
