Answer:
Explanation:
Given that,
Force, F = 52 N
Mass of the block, m = 4 kg
We need to find the acceleration of the object. We know that,
F = ma
Put the values,
So, the acceleration of the object is equal to 
.
Answer:
sound wave-electrical wave-radio wave
a =12miles
b =10miles
ab =2miles
Explanation:
at first the car is drown out of dealership and went 10 miles east and then 8 miles south
then your friend drives 8 miles west and 6 miles north.
then the distance it flies to get back to dealership is

12-10= 2 miles
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.
