The magma in the wake the core
Answer:
(a) 1.35 x 10^6 Joule
(b) 321.45 Kcal
Explanation:
Energy consumed in 1 hour = 270 kJ
So, Energy consumed in 5 hour = 270 x 5 = 1350 kJ
(a) Energy in joules = 1350 x 1000 J = 1.35 x 10^6 J
(b) 4.2 Joule = 1 calorie
So, 1.35 x 10^6 Joule = 1.35 x 10^6 / 4.2 = 0.32 x 10^6 Calorie
= 0.32 x 1000 Kcal = 321.45 Kcal
Answer:
El coeficiente de roce estático entre las dos superficies es 0.131.
Explanation:
El coeficiente de roce estático entre dos superficies (), sin unidad, es igual a la fuerza de resistencia (), en newtons, dividida por el peso del cuerpo a mover (), en newtons.
(1)
Donde:
- Masa, en kilogramos.
- Aceleración gravitacional, en metros por segundo al cuadrado.
Si sabemos que , y , entonces el coeficiente de roce estático es:
El coeficiente de roce estático entre las dos superficies es 0.131.
<h3>What is friction ?</h3>
Friction can be characterized as a drive that stands up to the relative movement of two objects when there surface comes in contact. Friction gives traction that's required to walk without slipping. Friction is supportive in most cases. In any case, they moreover offer a incredible degree of restriction to the movement. In addition, almost 20 per cent of the motor control of automobiles is expended in overcoming frictional strengths within the moving parts.
The four types of friction are:
- Static friction
- Sliding friction
- Rolling friction
- Fluid friction

Hey, how's your day going.
Your answer is (should be, but I haven't done the test) A,
rock samples from the moon.
The reason why we like to test "moon rocks" is because they are undisturbed for millions of years. Were as on earth we have lots of things that could mess up our dating (wind, water, animals, geological processes, etc.) That is why you can't tell the age of the solar system from your cack yard rocks.
(My reasoning ^, not the internets!)
