Discuss the effects of breaking a food chain.

Physics

Tom [10]3 years ago

8 0

Explanation:

Food chain is linear sequence of the organisms through which the nutrients and the energy pass as one organism eats the another.

<u>If one species in the food chain ceases to exist, the other members in rest of chain could cease to exist too or may increase in population which can affect other food chains. (Breaking of food chain).</u>

This is because the animals in the food chain are dependent on the nutrient present in the another.

For example in the food chain,

Grass ---- Deer ------ Lion

If all deer extinct, the lion will die as they will have nothing to feed on and the population of grass increases.

the law of reflection states that if the angle of incidence is 77 degrees the angle of reflection is

zzz [600]

Answer: 77 degrees

Explanation:

According to the Law of Reflection, when a ray of light strikes a surface, the angle of this ray (incident ray) with respect to the normal of the surface is equal to the angle that forms the reflected ray with the same normal of the surface.

In other words:

Both the incident ray and the reflected ray and the normal to the surface are in the same plane, in addition, the angle of the incident ray is equal to the angle of the reflected ray.

In this context, if the angle of incidence is 77 degrees, the angle of reflection is 77 degrees, as well.

What is the centripetal acceleration of the earth as it travels around the sun when Earth has an orbital radius of 1.5 x 10^11 m

masya89 [10]

Answer: $0.0058 m/s^{2}$

Explanation:

Centripetal acceleration $a_{C}$ is calculated by the following equation:

$a_{C}=\frac{V^{2}}{r}$

Where:

$V=29.7 \frac{km}{h} \frac{1000 m}{1 km}=29700 m/s$ is the Earth's orbital speed

$r=1.5(10)^{11} m$ is the orbital radius

$a_{C}=\frac{(29700 m/s)^{2}}{1.5(10)^{11} m}$

$a_{C}=0.0058 m/s^{2}$

Can you please help me? It’s a science question and I really don’t know the answer

Svetllana [295]

Answer:

A. It will continue traveling at the same speed.

Explanation:

I'm not 100% sure on this answer, but if I had this question I would be confident in this answer. It makes sense because unbalanced forces cause an object to start, stop, slow down, or speed up. Without these forces, the object should just keep traveling at the same speed.

I hope this helps! Let me know if it's right or not. ☺
