Answer:
a. chemical contamination of streams ans rivers
d. adaptation
Answer:
Basic kinematics, negating drag and assuming ideal conditions, we use the equation:
d=vi*t+1/2*a*t^2
Since vi is 0 (we know this because you’re dropping it, not throwing it)…
…and the only acceleration acting on it is gravity, a=9.8 m/s^2…
…we get
d=1/2(9.8)(5)^2
Explanation:
Some quick mental math tells us that this is about 125 m.
Plugging it in, we find it to be 122.5 m.
Closed is the correct answer :)
Answer:
Sabemos por definición que la fuerza es lo que es capaz de producir cambios o deformaciones en un cuerpo y a esto se denomina efecto estático y cuando la alteración ejerce movimiento o reposo se denomina efecto dinámico, con esta base resolvemos que:
-estirar un muelle: efecto estatico
- devolver una volea: efecto dinámico
- aplastar la plastilina: efecto estático
- empujar el carro del supermercado: efecto dinámico
- inflar un globo: efecto estático
In scientific notation, if the exponent of 10 is positive, the number is very very large. In the metric system, very large numbers are expressed in megameters (Mm) or gigameters (Gm). Gigameters is equal to 10⁹ meters. So, in SI prefix, that would be equal to 150 Gm. In kilometers, that would be equal to:
1.5×10¹¹ m * (1 km/1000 m) = 1.5×10⁸ km
