The mass of this bag of cement in S.I. units (kg) is equal to 0.062 kilograms.
<u>Given the following data:</u>
- Mass of cement = 62 grams.
To calculate the mass of this bag of cement in S.I. units (kg):
<h3>How to convert to
S.I. units.</h3>
In Science, kilograms (kg) is the standard unit of measurement or S.I. units of the mass of a physical object. Thus, we would convert the value of the mass of this bag of cement in grams to kilograms (kg) as follows:
<u>Conversion:</u>
1000 grams = 1 kilograms.
62 grams = X kilograms.
Cross-multiplying, we have:
X = 
X = 0.062 kilograms.

To solve this problem, we must remember about the law of
conservation of momentum. The initial momentum mist be equal to the final
momentum, that is:
m1 v1 + m2 v2 = (m1 + m2) v’
where v’ is the speed of impact
Since we are not given the masses of each car m1 and m2,
so let us assume that they are equal, such that:
m1 = m2 = m
Which makes the equation:
m v1 + m v2 = (2 m) v’
Cancelling m and substituting the v values:
50 + 48 = 2 v’
2 v’ = 98
v ‘ = 49 km/h
<span>The speed of impact is 49 km/h.</span>
Answer:
Asch (1956) found that group size influenced whether subjects conformed. The bigger the majority group (no of confederates), the more people conformed, but only up to a certain point.
Explanation:
A
Excitation to a higher energy state requires energy which is absorbed from the electromagnetic waves applied.
Answer:
c) It has a greater frequency than red light but a smaller frequency than blue light.
Explanation:
According to the relation:
c = frequency × Wavelength
The higher the frequency, the lower the value of wavelength
The order of wavelength is:
Violet < Indigo < Blue < Green < Yellow < Orange < Red
Stated above, frequency is inversely proportional to the wavelength. Thus, the order of wavelength is:
Violet > Indigo > Blue > Green > Yellow > Orange > Red
Thus,
<u>Green light has lower frequency than blue light and higher than red light.</u>
