An example of a a predator in the Ethiopian Highlands ecosystem is the
Wolf.The wolf is a carnivore which acts as a predator to other smaller
animals in the ecosystem.
<h3>What is a Prey?</h3>
Preys are mostly smaller animals in which the predators feed on for food.
They are usually herbivores and primary consumers in the ecosystem.
Examples of Preys include:

Answer:
47.8 °C
Explanation:
Use the heat equation:
q = mCΔT
where q is the heat absorbed/lost,
m is the mass of water,
C is the specific heat capacity,
and ΔT is the change in temperature.
Here, q = 100 kJ, m = 0.5 kg, and C = 4.184 kJ/kg/°C.
100 kJ = (0.5 kg) (4.184 kJ/kg/°C) ΔT
ΔT = 47.8 °C
A fixed container containing an ideal gas is heated. The pressure of the gas increases because the molecules move faster.
You can speed up the motion of the molecules in a gas by heating it. The pressure will rise and there will be greater impacts on the container's walls.
The container walls are pressed against by the combined force of the collisions. The energy you provide when you heat the gas makes the gas's particles more kinetically energetic and put more pressure on the container.
As the temperature rises, the pressure must as well since pressure is the force the particles per unit of area exert on the container.

Answer:
717 Hz
Explanation:
<u>solution:</u>
The wave with three antinodes has m = 3. Thus, f_3 = 3f_1 and so the fundamental frequency of the string is
f_1 =f_3/3
=430 Hz/3
=143 Hz
Thus, the frequency of the fifth harmonic is
f_5 = 5*f_1
= 5*143 Hz
= 717 Hz
Answer:
(a)The work done by the man is -15.03J.
(b)The force exerted on the object is 127.4N.
Explanation:
Mass of the object pulled by the man is -13kg
Object is lifted 11.8 cm vertical with his teeth it means (displacement = +11.8cm = +0.118m)
Acceleration due to gravity is 
(a) <u>Calculating the work done</u>:
Work done = mgh
Where "m" is mass of an object, "g" is acceleration due to gravity and "h" is the displacement.
The work done by the man is -15.03J.
(b) <u>Calculating the force</u>:
Probably the man and the object are close to the exterior of the earth. If the rigidity required to maintained the object of consistent velocity interior the gravitational field of the earth is 
Thus the weight of the object is balanced by the force of the man's teeth on the object. That is
F = mg
F = 127.4N
The force exerted on the object is 127.4N.
