The Earth's axis is tilted "away" from the Sun in the hemisphere. where
it's winter. The daytime is very short. That's because the Earth's axis
is tilted "away" from the Sun in the hemisphere.
Inertia is proportional to mass. It is a measure of the resistance to changes in velocity. Inertia is a property of mass and cannot change. Momentum changes as an object changes its velocity. Good luck on your assignment and have a great day! :D
Answer:
d. No, porque la ecuación de trabajo lo define.
Explanation:
En Física, el trabajo realizado se puede definir como la cantidad de energía transferida cuando un objeto o cuerpo se mueve a lo largo de una distancia debido a la acción de una fuerza externa.
Matemáticamente, el trabajo realizado viene dado por la fórmula;
<u>Dónde;</u>
- W es el trabajo realizado.
- F representa la fuerza que actúa sobre un cuerpo.
- d representa la distancia recorrida por el cuerpo.
Por lo tanto, podemos deducir de la definición de trabajo y su fórmula que el trabajo se realiza cuando un objeto (cuerpo) se mueve una distancia o experimenta cualquier forma de desplazamiento mientras transfiere energía.
Answer:
The energy that the truck lose to air resistance per hour is 87.47MJ
Explanation:
To solve this exercise it is necessary to compile the concepts of kinetic energy because of the drag force given in aerodynamic bodies. According to the theory we know that the drag force is defined by

Our values are:




Replacing,


We need calculate now the energy lost through a time T, then,

But we know that d is equal to

Where
v is the velocity and t the time. However the time is given in seconds but for this problem we need the time in hours, so,

(per hour)
Therefore the energy that the truck lose to air resistance per hour is 87.47MJ
Moles x Mol mass = mass.
<span>Having looked it up, the mol.mass of U-238 is 238.03g/mol. </span>
<span>7.50 moles x 238.03g/mol. = 1,785.23g/mol</span>
