Answer:
The number of atoms is the same in the reactants and in the products, and the total mass is the same in the reactants and in the products.
An area that is located near a mountain
Answer:
from fast-moving to slow-moving particles during particle collisions.
Explanation:
The molecules in every substance are constantly in random motion, which is called thermal motion. This means that they continuously move in random directions with random velocities. In particular, their speed depends on the temperature of the substance: the higher the temperature, the higher the average kinetic energy of the particles, the higher their speed.
However, not all particles move with same speed: some of them move faster, some of them move slower.
Since there are many particles, quite often these particles collide with each other: in the collision, energy is transferred from one particle to another.
In conduction, which is one of the 3 methods of heat transfer (the other 2 being conduction and radiation), the heat is transferred via collision between the molecules.
In particular, according to the laws of thermodynamics, energy is always transferred from particles moving faster (which have therefore more energy) to particles moving slower (which have therefore less energy).
So the correct answer is
from fast-moving to slow-moving particles during particle collisions.
Answer:
1500kg
Explanation:
Assuming that the women push the car in the same direction, then the total force is:
Fnet = 425 N ⋅ 3
= 1275 N
To find the mass, we use Newton's second law of motion, which states that,
F = ma
where:
·F is the force applied in newtons
·m is the mass of the object in kilograms
·a is the acceleration of the object in meters per second squared.
So we get:
F
m= ⁻⁻⁻⁻⁻
a
1275N
= ⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
0.85 m/s²
= 1500 kg
The stuff you dissolve is the SOLUTE. What you dissolve it IN is the SOLVENT.
