Answer:
Explanation:
Formula
The current = charge / time
The charge is in coulombs
The time has to be in seconds.
1 minute = 60 seconds
2 minutes = 120 seconds.
charge = 180 coulombs
current = 180 / 120
current = 1.5 amperes.
Answer:
78.75g
Explanation:
The density of diamond is the mass of diamond per unit of its volume. The density of a substance is calculated using the formula:
Density (g/cm^3) = mass (g) / volume (cm^3)
According to the question, the density of diamond= 3.15g/cm^3, volume of diamond= 25cm^3, mass = ?
Hence, to calculate the mass, we say;
Mass = Volume × density
Mass = 25 × 3.15
Mass = 78.75
Therefore, the mass of diamond is 78.75grams.
Atomic mass units is a unit of measurement of mass, same with grams. Therefore, we can convert the two measurements back and forth using a conversion factor. For every 1 amu, there are 1.66054×10⁻²⁴ grams. The solution is as follows:
(1.674×10⁻²⁴ g)(1 amu/1.66054×10⁻²⁴ g) = <em>1</em><em>.008 amu of neutrons</em>
