Answer:
louder sound.
Explanation:
The amplitude of a sound wave determines its loudness or volume. A larger amplitude means a louder sound
That only the best traits would go through. The weaker trait in the animals would eventually die off.
The mechanical advantage of the lever is 3 and the right option is A.) 3.
<h3>What is mechanical advantage?</h3>
Mechanical advantage can be defined as the ratio of load to effort in a machine.
To calculate the mechanical advantage of the lever, we use the formula below.
Formula
- M.A = y/x................ Equation 1
Where:
- M.A = mechanical advantage of the lever
- y = distance moved by effort (input arm)
- x = distance moved by load (output arm)
From the question,
Given:
Substitute these values into equation 1
Hence, The mechanical advantage of the lever is 3 and the right option is A.) 3.
