<h2>Apartment Explosion Reported </h2>
The apartment’s explosion, reportedly caused by a gas leak, produced a violent release of gas and heat. The heat increased the temperature of the air in the room, which means an increase in the air's molecular kinetic energy.
When heat is provided then temperature increases and the molecules of substances move rapidly by increase of kinetic energy (K.E) temperature increases. It is understood that heat increases temperature.
The net force acting on the two (2) kids is equal to 180 Newton.
<u>Given the following data:</u>
- Mass of kid 1 = 40 kilogram.
- Mass of kid 2 = 50 kilogram.
- Acceleration = 2

To determine the net force acting on the two (2) kids:
First of all, we would calculate the total mass of the two (2) kids:

Total mass = 90 kg.
<h3>
How to calculate net force.</h3>
In this exercise, you're required to calculate the magnitude of the net force that is acting on these two (2) kids running down the hall. Thus, we would apply Newton's Second Law of Motion.
Mathematically, Newton's Second Law of Motion is given by this formula;

Substituting the given parameters into the formula, we have;

Net force = 180 Newton.

To solve this problem, we can use the cosine formula for
calculating the length of the displacement:
c^2 = a^2 + b^2 – 2 a b cos θ
where c is the displacement, a = 3.5 km, b = 4.5 km, and θ
is the angle inside the triangle
Since the geeze turned 40° from west to north, so the
angle inside the triangle must be:
θ = 180 – 40 = 140°
c^2 = 3.5^2 + 4.5^2 – 2 (3.5) (4.5) cos 140
c^2 = 56.63
c = 7.53 km
<span>So the magnitude of the displacement is 7.53 km</span>
The similarity is that they both are types of bonds in molecules.
Ionic bonds are between a metal and a nonmetal.
Covalent bonds are between two nonmetals.
Answer:
The one with highest velocity
Explanation:
The momentum of an object is given by

where
m is the mass of the car
v is the velocity of the car
In this problem, we have two identical cars: identical means they have same mass, so

The momentum of car 1 is

while the momentum of car 2 is

By comparing the two expressions, we see that the car with greatest momentum is the one with highest velocity, since the mass is the same.
