The government should put it support in a combination of sources, as no
source in the present can fully provide all energy requirements.
Im not 100% on these but i can try
1. A compound is made up of elements and their different atoms
2.
A. salt- compound (NaCl) is two elements Na (sodium) and Cl (chloride?)
B. Nitrogen- element its on the periodic table
C. Helium- element its on the periodic table
D. Water- compound (H2O) two elements hydrogen and oxygen
3. element, compound, compound, element
Hope this helps
The steel would expand by 4. 8 * 10^-3 cm
<h3>How to determine the linear expansion</h3>
The change in length ΔL is proportional to length L. It is dependent on the temperature, substance, and length.
Using the formula:
ΔL= α LΔT
where ΔL is the change in length L = 10cm
ΔT is the change in temperature = 60° - 20° = 40° C
α is the coefficient of linear expansion = 1.2 x 10^-5 °C
Substitute into the formula
ΔL = 
ΔL = 
cm
Therefore, the steel would expand by 4. 8 * 10^-3 cm

<u>Answer:</u> The energy released in the given nuclear reaction is 3.526 MeV.
<u>Explanation:</u>
For the given nuclear reaction:
We are given:
Mass of 
= 41.962403 u
Mass of 
= 41.958618 u
To calculate the mass defect, we use the equation:
Putting values in above equation, we get:
To calculate the energy released, we use the equation:
(Conversion factor: 
)
Hence, the energy released in the given nuclear reaction is 3.526 MeV.
Answer: When you cannot stop safely at a yellow traffic light before entering an intersection, enter the intersection carefully and continue across.
Explanation: To find the correct answer, we need to know more about the traffic signal rules.
<h3>What is the traffic signal rules?</h3>
- Red light- Indicator for the motorists to stop.
- Green-Signal for safety and word GO.
- Yellow- This signal let you know that the red signal is about to be displayed.
- when it's turned on, you can start slowing down to come to a stop in anticipation of red light.
- when we cannot stop safely at a yellow traffic light before entering an intersection, enter the intersection carefully and continue across.
Thus, we can conclude that, the option C is correct.
