Answer:
The correct answer is combustibility
Explanation:
A chemical property of a matter is a property in which a matter has the tendency to change its form through chemical reaction(s).
A matter is said to have combustibility property if it can undergo combustion. Combustion is a chemical process in which a substance burns in excess oxygen to produce carbon dioxide and water.
Consider the equation below
CH₄ + O₂ ⇒ CO₂ + H₂O
The equation above shows methane burning in excess oxygen to produce carbon dioxide and water
The answer is electrical conductivity!
Duas cargas elétricas Q¹= 15.10-seis ao quadrado C e Q² = 150.10-seis ao quadrado, estão separadas por uma distância de 0,1m, no vácuo. Determine a intensidade da força elétrica de repulsão existente entre as cargas. Dá uma força ae clã!
Answer:
The electric field intensity of electric force is [tex]1.35\times10^{7}\ N/C[/tex]
Explanation:
Given that,
First charge [tex]q_{1}=15\times10^{-6}\ C[/tex]
Second charge [tex]q_{2}=150\times10^{-6}\ C[/tex]
Distance = 0.1 m
We need to calculate the electric field intensity of electric force
Using formula of intensity of electric force
[tex]E=\dfrac{F}{q_{2}}[/tex]
[tex]E=\dfrac{kq_{1}}{r^2}[/tex]
Put the value into the formula
[tex]E=\dfrac{9\times10^{9}\times15\times10^{-6}}{(0.1)^2}[/tex]
[tex]E=13500000\ N/C[/tex]
[tex]E=1.35\times10^{7}\ N/C[/tex]
Hence, The electric field intensity of electric force is [tex]1.35\times10^{7}\ N/C[/tex]
Explain newton 2nd law ???
Explanation:
Newton's second law simply says that the net force on an object is equal to the object's mass times its acceleration.
∑F = ma
For example, think of a game of tug-of-war, in which two teams pull on a rope in opposite directions.
If the forces are equal (balanced), then the net force is 0 N, so Newton's second law tells us that the rope's acceleration is 0 m/s².
If the forces are not equal (unbalanced), then the net force is not 0 N, and the rope will accelerate in the direction of the net force.

What are the 2 main parts of physical science
Answer:
Physical science is the study of the inorganic world. That is, it does not study living things. (Those are studied in biological, or life, science.) The four main branches of physical science are astronomy, physics, chemistry, and the Earth sciences, which include meteorology and geology.
Explanation:
A driver sees a boy and his dog in the road, and it takes the driver 0.50 seconds to put on the brakes. If the car travels 14 meters during that time, what is its velocity?
Answer:
The answer would be 91.9 or 91.8635
Hope this helps
A driver sees a boy and his dog on the road, and it takes the driver 0.50 seconds to put on the brakes, If the car travels 14 meters during that time, the velocity of the car would have been 56 m/s,
What are the three equations of motion?There are three equations of motion given by Newton
The first equation is given as follows
v = u + at
the second equation is given as follows
S = ut + 1/2×a×t²
the third equation is given as follows
v² - u² = 2×a×s
As given in the problem a driver sees a boy and his dog on the road, and it takes the driver 0.50 seconds to put on the brakes, If the car travels 14 meters during that time,
t = 0.5 s , s = 14 m
By using the first equation of the motion,
v = u+at
0 = u+a×0.5
a = -2u m/s²
Now by using the second equation of motion,
s = ut+1/2at²
By substituting t=0.5 and a = -2u m/s² in the equation ,
14 = u/2-u/4 = u/4
u = 56 m/s
Thus, the velocity of the car would have been 56 m/s,
