D
Explanation:
mass times velocity

Momentum is equal to mass times velocity. Therefore, option (D) is correct.
What is momentum?Momentum can be defined as the product of mass and velocity of object. Momentum can be defined as a standard mechanical quantity. Momentum can be considered as a vector quantity, exhibiting a magnitude and a direction.
If m is a body's mass and v is its velocity, then the body's momentum p is :
[tex]{\displaystyle \mathbf {p} =m\mathbf {v}[/tex]
In the System of Units (S.I.), the measurement unit of momentum is the kilogram meter per second (kg⋅m/s) or newton-second.
Newton's 2nd law of motion can be described as the rate of change in the momentum being equal to the net force acting. Momentum depends on the frame of reference, if a closed system is not affected by external forces, its total linear momentum will be conserved.
The unit of momentum can be described as the multiplication of the units of mass and velocity. In SI units the momentum is kg⋅m/s.

This dude was sitting in the chair. Someone pulls the chair out from under him. He does not move in the direction of the chair. He simply falls to the ground in the same spot he was sitting. This shows inertia because:
Answer:
This shows inertia because inertia is an object's resistance to change in motion. When the person (imma call them a she) who pulled the chair from under the guy did that, the chair was the one affected by the force of the girl, not the guy. The guy continued heading in the direction he was originally going, which was down.
At least, that's about how I would answer this question.

In the chemical reaction CH4 + 2O2 → CO2 + 2H2O, there are reactants on the left of the equation and products on the right. If you count the atoms in the reactants, there are
a. 4 carbon atoms, 4 hydrogen atoms, and 2 oxygen atoms
b. 1 carbon atom, 4 hydrogen atoms, and 2 oxygen atoms
c. 1 carbon atom, 4 hydrogen atoms, and 4 oxygen atoms
d. 4 carbon atoms, 4 hydrogen atoms, and 4 oxygen atoms
Answer:
the answer is A. 4 carbon atoms, 4 hydrogen atoms, and 2 oxygen atoms
The number of atoms of each molecule of the reactants is required.
The correct option is c. 1 carbon atom, 4 hydrogen atoms, and 4 oxygen atoms
The given reaction is
[tex]CH_4+2O_2\rightarrow CO_2+2H_2O[/tex]
For carbon atoms
The only carbon atom is present in [tex]CH_4[/tex]
So, 1 carbon atom
The hydrogen atoms are also present is [tex]CH_4[/tex]
There are 4 hydrogen atoms.
The oxygen atoms present is [tex]2\times 2=4[/tex]
So, the number of atoms present in the reactants are c. 1 carbon atom, 4 hydrogen atoms, and 4 oxygen atoms

Lightning flashes and you hear a thunder clap for seconds later. the velocity of sound is 340 m/s. how far away did lightning strike ?
Answer:
For metric-system conversions, follow this method: Sound travels at about 340 m/s, so multiply the number of seconds you counted by 340, and you'll know how many meters away lightning struck. A three-second count, then, would place the lightning strike about 1,020 m away, or roughly 1 km.
Explanation:
hope it hep and if it doesnt sorry
The distance struck by the lighting flashes is 680 m.
The given parameters;
time taken to hear the thunder clap, t = 4 svelocity of sound, v = 340 m/sThe distance struck by the lighting is calculated by applying the principle of echo as follows;
[tex]v = \frac{2d}{t} \\\\2d = vt\\\\d = \frac{vt}{2} \\\\d = \frac{340 \times 4}{2} \\\\d = 680 \ m[/tex]
Thus, the distance struck by the lighting flashes is 680 m.

Answer:
C. amount of charge on the source charge.
Explanation:
Electric field lines can be defined as a graphical representation of the vector field or electric field.
Basically, it was first introduced by Michael Faraday and it is typically a curve drawn to the tangent of a point is in the direction of the net field acting on each point.
The number, or density, of field lines on a source charge indicate the amount of charge on the source charge. Therefore, the density of field lines on a source charge is directly proportional to quantity of charge on the source.
