When the sources is not enough for a population size that would limit population growth are limiting factors. And these limiting factors prevent the population size to increase. When it stops growing, the ecosystem reaches its carrying capacity. <span>Carrying capacity is the end of the line of a population size that the ecosystem can support over time.</span>
Answer:

Explanation:
It is given that,
Mass of the car, m = 763 kg
Speed of the car, v = 26 m/s
Mass of the iron, m' = 15 kg
Specific heat of iron, c = 450 J/kg
When the car is in motion, it will possess kinetic energy. It is given by :


K = 257894 J
Since, energy is absorbed by the brakes. The kinetic energy of the car is absorbed by the brakes. So,

is the increase in temperature of the brakes



So, the increase in temperature of the brakes is 38.20 degrees Celsius. Hence, this is the required solution.
Answer:
Mass = 1450kg
Explanation:
P = M * V (where p is momentum, m is mass and v is velocity)
29000 = 20 * M
M = 29000 / 20
M= 1450 kg
The correct answer is B. Fuse.
Fuses were commonly used in houses up to recent ages, when circuit breakers became the more popular options, as they don't have to be changed every time they melt, since they don't melt.
Answer:
Walking burns up more energy,1740000J
Explanation:
Given that the displacement is 5.0km, and running at 10km/h and uses, walking at 3km/hr and uses 290watts:
Energy consumption for running is calculated as:

Energy consumption for walking is calculated as:

Walking is a slower process hence the need for more energy over longer periods raltive to running the same distance.
Hence walking burns more energy; 1,740,000J. It burns more because you walk for a greater period of time.
