mixas84 [53]3 years ago
7 0

Answer:

Combination or synthesis

Explanation:

The reaction is a combination or synthesis reaction in which two or more substances combines to give a single product.

In such a reaction there is formation of compounds from the union of their constituent elements.

 The driving force for such reactions is the large and negative heat of formation of the product.

So, this is a combination reaction.

How is Newtons second law apply to the egg drop ?
kotykmax [81]

Answer:

Newton's Second Law is applied because of the acceleration caused by natural forces as the egg is plummeting to the earth. And the amount of acceleration the egg has will be largely affected by the amount of force Mr. Baker uses to hurl the egg to the ground.

Which statements describe the energy in a food web? Check all that apply. When an organism eats another organism, it loses energ
Neko [114]

Answer:  Producers have the greatest amount of available energy.

When an organism eats another organism, it gains energy.

Explanation:

A food chain is a linear sequence of transfer of food and energy when one organism is eaten by the other organism. A food web is the interconnection of two or more food chains. This happens when one organism belong to one food chain also consume organisms of same food chain or other food chain. A food chain includes trophic levels on the basis of the mode of feeding of the living beings.

Among the options given, Producers have the greatest amount of available energy. and

When an organism eats another organism, it gains energy. are correct.

Producers are the organism which are capable of producing their food either through photosynthesis or chemosynthesis. They are present at the base level of the food chain. They consist of large amount of energy as compared to all the trophic levels in the food chain.

When one organism eats other organism it gains energy because of the assimilation and digestion of the organism as food.

In the photo, a locomotive has broken through the wall of a train station. During the collision, what can be said about the forc
Pavlova-9 [17]

Answer:

Whether the force exerted by the locomotive on the wall was larger

Than the force the locomotive could exert on the wall.

Explanation:

The Newton's third law of motion States that every force have it's equal and opposite reaction force, whose magnitude is the same as the applied force. Therefore the magnitude of these opposite forces will be equal.

So we have;

F12=-F21

F12 is the force in a direction

-F21 is the force in the opposite direction.

Therefore we see that the magnitude of the force the locomotive exerts on the wall is equal to the one the wall exerts on the locomotive. Both magnitudes are equal but in opposite directions.
