Why do most carnivores live in forest? given reason ​
kotegsom [21]

\huge\purple{Hi!}

most carnivore live in forest because

  1. They are highly dependent on flesh for their food and therefore their food is easily available in forests.
  2. Small animals live in forests that make it the ideal habitat for carnivores.
  3. Carnivores help in maintaining the herbivore population at a healthy level, by hunting.
  4. It all helps in keeping ecosystems in balance.

How is the wavelength of a longitudinal wave determined?
astraxan [27]

Answer:

Wavelength can always be found by measuring the distance between any two corresponding points on adjacent waves. In the case of a longitudinal wave, a wavelength measurement is made by measuring the distance from a compression to the next compression or from a rarefaction to the next rarefaction.

A fox runs at a speed of 16 m/s and then stops to eat a rabbit. If this all took 120
GalinKa [24]

Answer:

a = 52s²

Explanation:

<u>How to find acceleration</u>

Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.

<u>Solve</u>

We know initial velocity (u = 16), velocity (v = 120) and acceleration (a = ?)

We first need to solve the velocity equation for time (t):

v = u + at

v - u = at

(v - u)/a = t

Plugging in the known values we get,

t = (v - u)/a

t = (16 m/s - 120 m/s) -2/s2

t = -104 m/s / -2 m/s2

t = 52 s
