Answer:
a tough, light, flexible synthetic resin made by polymerizing ethylene, chiefly used for plastic bags, food containers, and other packaging.
Explanation:
J.J. Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. ... Rutherford's gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus.
Energy were released from the walnut, q = 1,673.6 J
<h3>Equation :</h3>
To find the energy using formula,
q = mcΔt
where,
q is charge
m is mass
c is specific heat of water
Δt is change in temperature
So, given
t₁ = 50°C
t₂ = 60°C
m = 40g
c = 4.184 J/g
Now putting the values known,
We get,
q = mc(t₂ - t₁)
q = 40g x 4.184 J/g x (60 - 50)
q = 167.36 J x 10
q = 1,673.6 J
<h3>What is heat energy?</h3>
Heat is the thermal energy that is transferred when two systems with different surface temperatures come into contact. Heat is denoted by the letters q or Q and is measured in Joules.

Answer:
F<S<Na<Ga<Sr
Explanation:
Atomic radius increased from the right of the periodic table to left, and from the top to the down
Answer:
7 cm
Explanation:
If the following digit is greater than or equal to 5, the decimal place is rounded up (moved up to the next number); if the following digit is less than 5, the decimal place stays the same.
4.6 + 2.35 = 6.95 cm
However, as stated in your question, cm is only being measured to the nearest 0.1 centimeters in your question.
So, you would round the digit 9 up by 1, meaning you would round it to 10. However, there are only nine digits available in our base-10 counting system, so you carry the value over,
6.95 cm could be rounded to '6. 100 cm', which is 7 cm.
