At first situation, ratio = x/y = 1/5
5x = y -------Equation (i)
Now, after adding 5 more red, it is = x + 5 / y+5 = 1/3
y+5 = 3(x + 5)
y + 5 = 3x + 15
y - 3x = 15 - 5
Substitute the value of y from equation (1),
5x - 3x = 15 - 5
2x = 10
x = 10/2
x = 5
Originally, There were 5 red marbles in the bag
Hope this helps!
The specific heat of the given sample of metal is 14.32 J/kg.K.
<h3>What is the Specific heat of a sample?</h3>
The specific heat of a sample is the amount of heat needed or required to raise the temperature of that sample by 1K. It is given by the formula:
Q = mCΔT
where;
- Q = Heat transferred
- m = Mass of the substance
- C = Specific heat
- ΔT= Change in temperature.
Recall that:
weight of a substance = mass × gravity
- mass = 28.4 N/ 9.8 m/s²
- mass = 3 N/m/s² = 3 kg
From the equation:
Q = mCΔT
C = 14.32 J/kg.K
