Answer:
Distance = 0.738 m
Explanation:
Solution:
<u>
First convert Km/h into m/s.</u>
75 km/h * 1000 m/km * 1 hr/3600 sec = 20.8333 m/s
<u>According to third equation of motion:
</u>
– 
= 2 * acceleration * distance
<em>
Vf= final velocity </em>
<em>Vi= initial velocity</em>
putting values in third equation of motion....
– 
= 2 * (-30 * 9.8) * distance
note:
negative sign is due to deceleration
Distance = 0.738 m
Based on the chemical reaction, Carbon reacts with Oxygen would yield Carbon Dioxide, we can imply that the "<span>Atoms are always conserved during chemical reactions." It is one of the fundamental concepts in chemistry wherein the mass is always conserved in a reaction since it can't be created nor destroyed.</span>
Answer: coal
Explanation: Nonrenewable energy resources include coal, natural gas, oil, and nuclear energy. Once these resources are used up, they cannot be replaced, which is a major problem for humanity as we are currently dependent on them to supply most of our energy needs
Answer:
Chemical energy, Energy stored in the bonds of chemical compounds. Chemical energy may be released during a chemical reaction, often in the form of heat; such reactions are called exothermic.
Answer:
The work done by the force on the particle is 29.85 J.
Explanation:
The work is given by:
Where:
x₁: is the lower limit = 0 m
x₂: is the upper limit = 1.9 m
Fₓ: is the force in the horizontal direction = (4.5 + 13.7x - 1.5x²)N
Therefore, the work done by the force on the particle is 29.85 J.
I hope it helps you!
