Answer:
b. The side the boy is sitting on will tilt downward
Explanation:
Initially, the seesaw is balanced because the torque exerted by the boy is equal to the torque exerted by the girl:
where
Wb is the weight of the boy
db is the distance of the boy from the pivot
Wg is the weight of the girl
dg is the distance of the girl from the pivot
When the boy moves backward, the distance of the boy from the pivot (
increases, therefore the torques are no longer balanced: the torque exerted by the boy will be larger, and therefore the side of the boy will tilt downward.
Reptiles, such as snakes and lizards, are cold-blooded animals. This means that they do not have the ability to control their body heat. For this reason, they often lay out in the sun to warm up. If their enviornent is cold they obtain that body temperature. They are very slow in colder environments.In cold weather these animals have a very difficult time moving because their muscles are very cold. Without heat in their environment, they cannot warm them up.
