Answer:

To protect you from fatal injuries and keep you secured in the case of an accident (my definition)

Explanation:

(Definition) Being buckled up during a crash helps keep you safe and secure inside your vehicle; being completely ejected from a vehicle is almost always deadly. If you don't wear your seat belt, you could be thrown into a rapidly opening frontal air bag. Such force could injure or even kill you.

if you wanted to increase the energy of a wave but you had to leave the wavelength the same what might you do

Blizzard [7]

Answer:

Increase the amplitude

Explanation:

The energy conveyed by a wave is directly proportional to the square of its amplitude. Thus; E ∝ A²

This means that increasing the amplitude will lead to an increase in the energy.

Now, the amplitude of a wave is the height of a wave from it's highest point known as the peak, to the lowest point on the wave known as the trough whereas wavelength refers to the length of a wave from one peak to the next.

This means that increasing the amplitude has no effect on the wavelength.

Larger animals have sturdier bones than smaller animals. A mouse's skeleton is only a few percent of its body weight, compared t

Rama09 [41]

Answer:

$a_s=4.8\times 10^{-2}~m^2$

Explanation:

Given:

cross sectional area of the bone, $a=4.8 \times 10^{-4} ~m^2$

factor of up-scaling the dimensions, $s=10$

Since we need to find the upscaled area having two degrees of the dimension therefore the scaling factor gets squared for the area being it in 2-dimensions.

The scaled up area is:

$a_s=a\times s^2$
