Answer:Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight available in an environment. Limiting factors are usually expressed as a lack of a particular resource.

Answer:
The ball took 0.4 seconds
Explanation:
» From the second newton's equation of motion.
- s is displacement, s = 80cm, s = 0.8 meters
- u is initial velocity, u = 0 [ from rest ]
- g is 10 m/s²
10km/hr or 80mph is the possible answer I can give
An unbalanced force.
Newton's first law states that an object in motion will stay in motion until a unbalanced force acts upon it.
<h3>Answer:</h3>
C) 500,000 J
<h3>Explanation:</h3>
The change in potential energy is ...
Mgh = (1000 kg)(9.8 m/s^2)(50 m) = 490,000 J . . . . roughly matches C
_____
<em>Comments on the problem</em>
The efficiency of the motor is unknown, so the amount of energy spent as heat is unknown.
In the equation above, we have used M for mass, and m for meters. The acceleration due to gravity is approximately 9.8 m/s^2, varying depending on location and height above the Earth. The "standard" value for g will add a few more joules to this value, but will not make it 500,000.
