<u>The S.I unit for the given term:</u>
Mass is expressed in kilogram (kg)
temperature is expressed in kelvin (K)
Time is expressed in seconds (s)
Current is expressed in ampere (A)
<u>Explanation:</u>
<u>Current:
</u>
The current can be defined as the electric charge flow in the surface (means ratio of charge per unit time). It is measured in ampere (A)

<u>Temperature:
</u>
Kelvin (K), the general temperature unit in the international standard units system. The Kelvin scale is an absolute thermodynamic temperature scale that uses absolute zero, a temperature at which all thermal movements end with a classic description of thermodynamics.
<u>Mass:
</u>
Mass is both a feature of the objects weight and its resistance measurement to accelerate under the influence of pure force. The mass of the object also determines the gravitational force. The basic unit of mass is kilogram (kg)
<u>Time:
</u>
Time is the measurement of how much distance the objects takes to travel from one to another (speed). It is expressed in seconds (s).
Answer:
pH scale
Explanation:
pH scale -
In the field of chemistry , the accurate and exact value of acidity or basicity in a particular solution is calculated with the help of a pH scale .
The scale has reading ranging from 1 to 14 ,
where ,
- If the pH value less than 7 indicates the solution to be acidic in nature ,
- If the pH value is exactly equal to 7 , the solution is neutral in nature ,
and ,
- If the pH value more than 7 indicates the solution to be basic in nature ,
Hence , from the given statement of the question ,
The correct answer is pH scale .
Answer:
8.58 g/cm3
Explanation:
density = mass / volume
be attention that the question gives u the length of
one side of the cube so u should calculate the volume
of the cube using your information of math .
1st we calculate the volume of the cube :
V of cube = a 3= axaxa
= 0.250 x0.250 x0.250
= 0.0156 cm3
2nd step
density = mass/volume
= 0.134/ 0.0156 = 8.58 g/cm3
