Neuroscientist mostly agreed that there is no agreed-on benchmark, that a brain is fully developed. However, it is safe to say that brain is continuing to developed well past at the age of "18". Brain development happen in different stages and all in varying times. Brain consist of gray matter and white matter. Gray matter grows as we learn, as puberty sets in, our brain starts to prune back some of the gray matter, and produces more white matter, to share information better and faster. Overall most neuroscientist agree that, there is no magic age at which the brain reaches adulthood, but about age 22 or 23, the brain is pretty much done developing.

Answer:
d)energy
Explanation:
Waves can transfer energy over distance without moving matter the entire distance. For example, an ocean wave can travel many kilometers without the water itself moving many kilometers. The water moves up and down—a motion known as a disturbance. It is the disturbance that travels in a wave, transferring energy.
Because the air inside the tires is kept at high pressure.
In fact, the force applied by the tires upwards to counter-balance the weight of the car (pushing downwards) is
where p is the pressure of the air inside the tires and A is the area of contact between the tire and the car. Therefore, a higher pressure means a larger force F, and eventually if the pressure p is higher enough the force F will be large enough to counterbalance the weight of the car.
