Answer:
68.25 kJ
Explanation:
The thermal energy Q required to raise the temperature of 15kg gold from 45⁰ C up to 80⁰ C is Q = mcΔθ where m = mass of gold = 15 kg, c = specific heat capacity of gold = 130 J/kg°C and Δθ = temperature change = θ₂ - θ₁ where θ₁ = 45 °C and θ₂ = 80 °C
So, Q = mcΔθ = mc(θ₂ - θ₁)
= 15 kg × 130 J/kg°C × (80 °C - 45 °C)
= 1950 J/°C × 35 °C
= 68,250 J
= 68.25 kJ

Daniel Wiseman, a scientist for Gres-Trans Corp., wants to determine if the flow rate of a particular material changes with different changes in temperature. The data is plotted in the figure below. What type of relationship exists between the flow rate and the change in temperature? negative curved positive there is no relationship
Answer: C. There is no relationship
Explanation:
At the various temperatures, the flow rates do not seem to show any relation as similar temperatures can yield different flow rates.
The flow rates neither appear to generally increase nor decrease as a result of a decrease or an increase in temperature which means that there is a lack of a positive, negative and curvilinear relationship.
There is simply no relationship.

Explanation:
i have two numbers that sum to 16 and have a difference of 3. by forming two equations and solving them, find the two numbers
Answer:
(x=9.5 and y=6.5) or ( x=6.5 and y = 9.5)
Explanation:
Let equations be
x+y = 16
If
x-y = 3
Now, Adding both equations, we get
x+y+x-y = 16+3
2x = 19
x=19/2 = 9.5
y = 16-9.5 = 6.5
Now y-x = 3
Now, Adding both equations, we get
x+y+y-x = 16+3
2y = 19
y=19/2 = 9.5
x = 16-9.5 = 6.5
4. Long term marijuana use can cause
4 ft – 6 ½ in. to inches. Record your answer in fractional inches.
Given that
4 ft – 6 ½ in.
To find,
We need to convert it it inches.
Solution,
We know that,
1 foot = 12 inches
4 feet = 4×12 inches
= 48 inches
[tex]4\ ft-6\dfrac{1}{2}\ in=48\ in+6\dfrac{1}{2}\ in\\\\=48+\dfrac{13}{2}\\\\=54.5\ \text{inches}\\\\=\dfrac{109}{2}\ \text{inches}[/tex]
Hence, 4 ft – 6 ½ in = 54.5 inches = 109/2 inches
