Answer:

T = 190 N

Explanation:

When child is sitting on the swing then the weight of the child is vertically downwards

So it is

F_g = 160 N

now a force of 100 N is acting on the swing in horizontal direction

so it is given as

F_x = 100 N

now the net force is resultant force due to gravity and horizontal force

so it is given as

T = \sqrt{F_x^2 + F_g^2}

T = \sqrt{100^2 + 160^2}

T = 190 N

A trait of an organism that helps it survive in its environment is calles
kompoz [17]
Answer is adaptation. An organism develops a trait over time to help survive in its environment called an adaptation. You could take a giraffe for example. A long time ago giraffes actually had short necks, but now since their food is higher they soon developed a longer neck and this is what we now see in the present. This goes for any artic animal. Polar bears and seals have a white fur adaptation to help them blend in with their environment. A chameleon changes colors in order to hide from predators and sneak up on prey. These are all adaptations
