Answer: Four electrons
Explanation:
The number of electrons that can be accepted by carbon from other atoms while bonding is four. The correct option is D.
What is chemical bonds?A chemical bond is what holds atoms in molecules together. Electrostatic forces between positively charged atomic nuclei and negatively charged electrons, the positions of which in space are determined by quantum mechanics, generate bonds.
Atoms form chemical bonds to strengthen their outer electron shells. The chemical bonding type maximizes the stability of the atoms that form it.
Carbon forms covalent bonds with other elements or carbon atoms. Carbon compounds are extremely diverse, with sizes ranging from one to thousands of atoms.
Because carbon has four valence electrons, it can form four covalent bonds to achieve a full outer energy level.
Thus, the correct option is D.

A car starting from rest accelerated at a rate of 0 .5 m/s up to 2 km what would be the final velocity of the car and how much time would it take to cover 1.6
Using third equation of kinematics
[tex]\\ \rm\longmapsto v^2=u^2+2as[/tex]
[tex]\\ \rm\longmapsto v^2=0^2+2(0.5)(1.6)[/tex]
[tex]\\ \rm\longmapsto v^2=1.6[/tex]
[tex]\\ \rm\longmapsto v=\sqrt{1.6}[/tex]
[tex]\\ \rm\longmapsto v=0.4m/s[/tex]
Now using 1st equation of motion

in the Newton's Third Law of Motion state three characteristics
Answer:
Newton's third law: If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A. This law represents a certain symmetry in nature: forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself.

Which statement is true?
A. When a gas condenses to a liquid, it absorbs energy.
B. When water boils, it releases energy.
C. When ice melts, it absorbs energy.
D. When water freezes, it absorbs energy.
Explanation:
The correct answer is option B
Answer:
C. When ice melts, it absorbs energy.
Explanation:
When ice melts, it is getting hotter by absorbing energy and changes from a solid to a liquid. This is an endothermic reaction.

A cyclist travels at 15 m/s during a sprint finish. What is this speed in km/h
Answer:
54km/hr
Explanation:
Since we have to complete m/s to km/h.
we can simply divide the m/s by (5/18)
so we get 54km/hr
Convert: 110 km/h to m/s
Answer:
30.5555556 m/s
You can write like "30.56 m/s".
Answer:
Below
Explanation:
You can convert km/h to m/s by dividing the value by 3.6
110 km/h / 3.6 = 30.5556 m/s
*not sure if your teacher wants you to round to sig figs for this but here it is anyways. Because 110 has 2 sig figs it would be :
31 m/s
Hope this helps! Best of luck <3
Round 0.010229 to four sig figs
It would be 0.01023.
0.010229 has 5 sig. fig.'s (leading zeros do not count)
So rounding to 4 sig. fig.'s is just a matter of rounding off the last digit, which leaves you with 0.01023.
how is light reflected from a prism
Answer:
White light entering a prism is bent, or refracted, and the light separates into its constituent wavelengths. Each wavelength of light has a different colour and bends at a different angle. The colours of white light always emerge through a prism in the same order—red, orange, yellow, green, blue, indigo, and violet.

When is the pressure of the man on the ground more – lying position or standing
position? Explain.
Hi,
The man on the ground in standing position has more pressure. This is because when he stands, only his legs are in contact with the ground. While lying, his body is more in contact with the ground, therefore, he exerts less pressure.
To the point, a man standing position on the ground had more pressure.
More is the area of contact, less is the pressure efforted.
Thank you...
