Answer=
low-frequency EMFs pose little danger to human health. ... Exposure to large levels of high-frequency EMFs is known to damage human DNA and cells
Explanation:
Different lever designs can be engineered and developed to alter the brake pedal effort required of the driver by using different levels of <u>mechanical advantage</u>.
<h3>What is
mechanical advantage?</h3>
Mechanical advantage can be defined as a ratio of the output force of a lever to the force acting on it (input force or effort), assuming no losses due to wear, flexibility, tear or friction.
This ultimately implies that, different lever designs can be suitably engineered and developed to alter the brake pedal effort (input force) that is required of the driver, especially by using different levels of <u>mechanical advantage</u>.
