Answer: d. all of the above
Explanation:
A wildfire can be either naturally occurring or induced by humans for their own benefit. Is likely to exert a negative impact on the wildlife. A fire is likely to spread quickly to the entire canopy cover of the forest trees. This will destroy the availability of food and other resources. Many birds and animals will loose their habitat or shelter. The destruction of the floral species will cause migration of the faunal species to other locations. Therefore, the biodiversity of the region will be lossed.
Velocity= 1/4 = 0.25 m/s towards the ball
Answer:
100 m/s
Explanation:
here we use the wave equation which states that the velocity is equal to the product of the frequency and the wavelength.
so v = 50 × 2
v = 100 m/s
Answer:
c) is negative
Explanation:
As we know that work done by a force is the product of force and displacement vector.
W= F.d
F= Force
d= displacement
The work done by friction force always negative because it try to oppose the motion and act opposite to the direction of displacement.So the work done by air resistance is negative.
c) is negative
