Answer:
0.5 m/s
Explanation:
Velocity = displacement/time taken
going 15 meters east and then 20 meters west gives a displacement of 5 meters.
Velocity v = 5/10
= 0.5 m/s
Answer:
Supongo que quieres encontrar las relaciones que te permiten cambiar las escalas de temperatura.
Las 3 escalas de temperatura son:
°C = grado Celcius.
°F = grado Farenheit.
K = grado Kelvin.
Empezamos con °C, pues es la mas conocida.
La diferencia entre consecutivos grados es la misma en la escala Kelvin que en la escala Celcius, pero la escala Kelvin esta definida de tal forma que el cero Kelvin representa la ausencia absoluta de temperatura, mientras que en Celcius podemos tener temperaturas menores a 0 grados.
La transformación entre Celcius y Kelvin es:
x °C = (x + 273.15) K
Es decir, agarramos nuestra temperatura en °C, y le sumamos 273.15 grados.
La transformación entre Celcius y Farenheit es:
x °C = ((x*9/5) + 32) °F
Y la faltante, va a ser de Kelvin a Farenheit, que es:
x K = ( ( (x - 273.15)*9/5) + 32) °F
Answer:
Strains can be acute or chronic. An acute strain is caused by trauma or an injury such as a blow to the body; it can also be caused by improperly lifting heavy objects or over-stressing the muscles. Chronic strains are usually the result of overuse--prolonged, repetitive movement of the muscles and tendons.
Explanation:
This inaugural journey may be slow-going for those who already know their way around the solar system, as our place in it is explained by a “cosmic address” (Earth<span>, solar system, Milky Way, local group, Virgo supercluster, observable universe), but interest will be held by the sharp and mesmerizing graphics.</span>
To determine the volume of the aluminum given that it has the same mass as the iron given, we need to divide the mass with the density of aluminum. We calculate as follows:
Volume of aluminum = 70.83 / 2.70 = 26.23 cc
Hope this answers the question. Have a nice day.
