Answer:
Higher percentage of runoff water is absorbed by the vegetation whereas 100 % of water runoff on the roofed area.
Explanation:
Higher percentage of runoff water is absorbed by the vegetation and very little amount of runoff water is received on the end of vegetative cover while on the other hand, 100 percent of precipitation water runoff on the surface of roofed or paved area because no water is absorbed by the roof due to its solid surface. The percentage of runoff depends on the factors such as rainfall intensity, slope, soil water storage capacity, and infiltration rate.

Explicación:
La energía cinética es la energía que posee un cuerpo en virtud de su movimiento. Sea la masa del cuerpo m, su velocidad v.
Energía cinética = 1/2 mv²
Parámetros dados
masa del coche = 500 kg
velocidad = 100 km / h
La velocidad debe estar en m / s según la unidad internacional estándar. Al convertir;
100 km / h = 100 * 1000/3600 m / s
100 km / h = 27,8 m / s
velocidad del cuerpo = 27,8 m / s
Necesario
Energía cinética del coche = 1/2 * 500 * 27,8²
Energía cinética del automóvil = 1/2 * 500 * 771.6
Energía cinética del automóvil = 1/2 * 385,801.28
Energía cinética del automóvil = 192,900.64 Julios
<em>Por lo tanto, la energía cinética del automóvil es 192,900.64 julios.</em>
Answer:
Unusually large moons form in giant impacts, which are relatively rare events
Explanation:
Solution:
- Finding large moons comparable in size to their planets result from impacts of two astro-bodies. The probability of such an event occurring is very rare.
- Even at the best luck, one moon can be made from the result of giant impact. While the probability of 6 planets having moons of comparable sizes is close to impossible. The transition from an undifferentiated cloud to a star system complete with planets and moons takes about 100 million years.
Answer:
5000 kg.m/s
Explanation:
Before collision, momentum of 100 Kg is given by
p=mv where p is momentum, m is the mass of object and v is the velocity,
therefore, the momentum=100*50=5000 kg.m/s
The momentum of the 50 Kg is zero since it's at rest hence v=o
Total momentum before collision is therefore 5000+0=5000 kg.m/s
