Winter weasels, also called ermines or short-tailed weasels, have coats that turn from light brown to white in the winter. The color change begins at their stomachs and works its way outward, occurring in both spring and fall. Other species, like the long-tailed weasel, may turn at least partially white as well.
The length of daylight, not temperature, prompts the color change. As a result, weasels in winter may be stark white against a brown landscape before snow starts to fall. During warmer winters, this makes them easy prey for larger predators such as foxes, martens, and badgers.
Answer:0.15 m/sec
Explanation:
To calculate speed you use distance over speed
18.3/122= 0.15

Without air resistance, the ball would reach a height of h = 31.9 m(pic 1)
The gravitational potential energy difference would be ΔU = 62.588J - 43.164J = 19,424J (pic2 + 3)
The work done by air resistance must be equal to the energy difference(pic4)
The magnitude of the air resistance: F = 0.883N
Answer:
Newton's Second law
Explanation:
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
