Answer:
B.KEEN EYESIGHT thats for predators !
Explanation:
Herbivores have multiple stomachs to process tough foods, coats to blend in so they don't get eaten, and tough teeth for chewing on the plants. THEY DO NOT HAVE PREY, THEY ARE THE PREY.
Answer:
24 m
Explanation:
The motion of the car is a uniformly accelerated motion (=at constant acceleration), therefore we can find the distance covered by using the following suvat equation:

where
s is the distance covered
u is the initial velocity
t is the time elapsed
a is the acceleration
For the car in this problem:
u = 0, since the car starts from rest
is the acceleration
t = 4 s is the time elapsed
Therefore, the distance covered is:

Answer:
The velocity
of the cart with respect to the ground is

if we consider North the positive y-direction and East the positive x-direction.
Explanation:
We have for relative motion the following expression:

Where
is the velocity of the cart with respect to the ground,
is the velocity of the cart with respect to the plane and
is the velocity of the plane with respect to the ground.
We find that:


Thus:
Answer:
I₂ = 2.13 x 10⁻⁸ W/m²
Explanation:
given,
increase in sound level = 28.1 dB
frequency of the sound = 250 Hz
intensity = 3.3 x 10⁻¹¹ W/m²
Intensity delivered = ?
the difference of intensity level is give as






I₂ = 645.65 I₁
I₂ = 645.65 x 3.3 x 10⁻¹¹
I₂ = 2.13 x 10⁻⁸ W/m²
