Answer:
6
6 significant digits
Explanation:
Number of significant digits of a number are the number of digits that carry a relevant contribution to the measurement.
For the case above;
104.100
rule - all digits to the right of the decimal of any number equal or greater than 1 will count as a significant digit.
104.100 --- .100 ( the three digits counts)
And since the the digits to the left are none zero digits, so they all count as significant digits.
104.100 --- 104 ( the three digits counts)
The total number of significant digits,
Since all the digits of the number 104.100 will count as a significant digit.
The number of significant digits is equal to the number of digits in the number.
N = 6
6 significant digits
Answer:
8.1Ns
Explanation:
Impulse is expressed as the product of Force and time
Impulse = Ft
F is the force = 180N
Get the time using the equation of motion
v = u+at
18 = 0+F/m(t)
18 = 180/0.45(t)
18 = 400t
t = 18/400 secs
Recall that;
Impulse = Ft
Impulse = 180×18/400
Impulse = 8.1Ns
Hence the impulse imparted to the ball is 8.1Ns
1) They are packed with vitamins and minerals.
2) They are rich in antioxidants.
3) They are rich in dietary fibre and they are good for digestion.
4) They can fight cancer, diabetes and heart disease.
5) They are important for maintaining a healthy body.
Having in mind that a spontaneous process is capable of proceeding in a given direction without needing to be driven by an outside source of energy, then it must occur naturaly. This is actually spontaneous. Also take into account that in order to define a spontaneous pattern we need to state no work performed on the system or on the surroundings.
