Answer:
A. 0 N
Explanation:
One force is subtracted from the other to calculate the net force. If the opposing forces are equal, or balanced, the net force is zero.
Hope this helps!
The six steps of the scientific are:
1. State the question
2. Conduct research
3. Create a hypothesis
4. Perform the experiment
5. Analyze the data
6. Conclusion
So D. would be the correct answer, even though communicating the results could possibly be a step if it's required.
Answer:
The answer is
<h2>324 K</h2>
Explanation:
To express a given temperature in degree Celsius to Kelvin simplify add 273 to the given value
That's
<h3>K = 273 + °C</h3>
where
K = Kelvin
°C = value in degree Celsius
From the question the value to be converted is 51°C
It's equivalent in Kelvin is
K = 273 + 51
We the final answer as
<h2>324 K</h2>

The energy transferred is 28.5 j
<em><u>calculation</u></em>
energy is calculate MCΔT formula where,
M(mass)= 6.30 grams
C(specific heat capacity)= 0.377 j/g
ΔT(change in temperature)= 32.0c- 20 c= 12 c
Energy is therefore= 6.30 g x 0.377 j/g /c x 12 c =<u>28.5 j</u>
Answer:
Final pressure = 362.7 Pa
Explanation:
Given that,
Initial volume, V₁ = 930 ml
Initial pressure P₁ = 156 Pa
Final volume, V₂ = 400 mL
We need to find the final pressure. We know that the relation between volume and pressure is inverse i.e.
So, the final pressure is equal to 362.7 Pa.
