The magnitude of v⃗ is {sqrt(m1v1)2+(m2v2)2/ m1+m2}, that is, the speed v of the two-car unit after the collision.
<h3>What is
collision?</h3>
- In physics, collisions occur when particles, aggregates of particles, or solids come close to each other, interact and affect each other.
- Collisions are of three types Fully elastic collision, inelastic collision and Perfectly inelastic collision.
- Multiply the mass of the second object by its velocity.
- For example, if the weight is 1,000 and the speed is -30 meters per second, then its momentum is 30,000 kg meters per second.
- Add the two velocities together to determine the direction the object will move after a collision.
- So the formula for determining the size of a vector (in 2D space) is v = (x, y).|v| = √(x2 + y2).
- This formula is derived from the Pythagorean theorem.
- The formula V = (x, y, z) that determines the size of a vector (in 3-dimensional space) is:|V| = √(x2 + y2 + z2)

The DNA chain is 364 times smaller than the complex virus.
<h3>
How small if the DNA chain?</h3>
The size of the DNA chain is calculated as follows;
relative size of DNA chain = size of complex virus/size of DNA chain
relative size of DNA chain = 171 mm / 0.47 mm
relative size of DNA chain = 363.83 = 364
Thus, the DNA chain is 364 times smaller than the complex virus.

Answer:
Nuestro mejor amigo escuchará la música más rápido a una temperatura de 36 ºC (309.15 K)
Explanation:
Supongase que el aire se comporta como un gas ideal y que experimenta un proceso adiabático, entonces la velocidad del sonido (), medida en metros por segundo, queda traducida en la siguiente fórmula:
(1)
Donde:
- Coeficiente de dilatación térmica, sin unidad.
- Coeficiente universal de los gases ideales, medido en kilogramo-metros cuadrados por mol-Kelvin-segundo cuadrado.
- Temperatura, medida en Kelvin.
- Masa molar, medida en kilogramos por mol.
Como se puede ver, la velocidad del sonido es directamente proporcional a la raíz cuadrada de la temperatura. Por tanto, nuestro mejor amigo escuchará la música más rápido a una temperatura de 36 ºC (309.15 K)
Answer:
With an increase in temperature, there is typically an increase in the molecular interchange as molecules move faster in higher temperatures. The gas viscosity will increase with temperature. ... With high temperatures, viscosity increases in gases and decreases in liquids, the drag force will do the same.
Answer:
if the frequency is double, the wavelength is only half as long
