Answer:

A rocket is an example of conservation of momentum where the mass of the system is not constant, since the rocket ejects fuel to provide thrust. The rocket equation gives us the change of velocity that the rocket obtains from burning a mass of fuel that decreases the total rocket mass

A reasonable estimate for the height of the walls in an ordinary american home is?
Olegator [25]

A reasonable estimate for the height of the walls in an ordinary American home is 2.5m.

<h3>What is wall estimation?</h3>

Building gauge is of two sorts one is known as Rough Cost Estimate. This gauge won't depict the specific expense of the structure, however it can provide you with the rough expense worth of the structure that will help adequately in overseeing cash for the structure. Harsh Cost Estimate is directed in various ways for various sort of structures. The rough complete wall length is found in running meters in this framework and this all out length accumulated by the rate per running meter of the wall gives an actually solid cost. Assessment hypothesis is a part of insights that arrangements with assessing the upsides of boundaries in light of estimated experimental information that has an irregular part. The boundaries depict a fundamental actual setting so that their worth influences the circulation of the deliberate information.

Sobre un barco, que se mueve en forma rectilínea, y con velocidad constante de 30 [km/h], se mueve un perro en el mismo sentido
almond37 [142]

Answer:

El observador verá correr al perro sobre la cubierta del barco a una velocidad de 40 kilómetros por hora.

Explanation:

Para determinar la velocidad del perro con respecto al observador sentado desde la playa a través del concepto de velocidad relativa, descrito en la siguiente fórmula:

v_{P/B} = v_{P} - v_{B} (1)

Donde:

v_{P/B} - Velocidad del perro relativo al barco, en kilómetros por hora.

v_{P} - Velocidad del perro con respecto al observador, en kilómetros por hora.

v_{B} - Velocidad del barco con respecto al observador, en kilómetros por hora.

Si sabemos que v_{B} = 30\,\frac{km}{h} y v_{P/B} = 10\,\frac{km}{h}, entonces la velocidad del perro con respecto al observador es:

v_{P} = v_{B} + v_{P/B}

v_{P} = 30\,\frac{km}{h} + 10\,\frac{km}{h}

v_{P} = 40\,\frac{km}{h}

El observador verá correr al perro sobre la cubierta del barco a una velocidad de 40 kilómetros por hora.

What explains the dramatically different magnitudes of accelerations that result when a mosquito collides head on with a moving
Evgen [1.6K]

Answer:

Mass of the vehicle and small bug.

Explanation:

  • By Newton's third law, force on bug and vehicle will be same when they collide with each other irrespective of their masses.
  • But according to Newton's second law, force is mass times acceleration. Since the force on each mass is same, the smaller mass will accelerate more and the heavier mass will accelerate less for the same force.
  • Therefore the acceleration of bug will be very greater than vehicle as the mass of the bug is very small as compared to vehicle.

What does Newton's second law describe?
Misha Larkins [42]
B. Newton's second law says that “when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate.”
