The speed of the object can be calculated using the formula:
Speed = distance/time
The given values are:
distance = 62.43 m
time = 38.4 s
Solution:
speed = 62.43 m / 38.4 s = 1.63 m/s
Therefore, the speed of an object that travels 62.43m in 38.4s is <span> 1.63 m/s.</span>

Answer:
Explanation:
Input refers to the amount of energy put into a device, and output refers to the amount of energy that comes out. A device may change the type of energy but not the amount. For example, a light bulb's input energy is the form of electrical energy, and its output energy is in the form of light and heat. Efficiency.
Neither the speed nor the distance of a falling object is linearly related to time.
<span>So we want to know what kind of wave is the scientist is studying while studying earthquakes. Waves that produce earthquakes are mechanical waves. Gamma rays and radiowaves are both electromagnetic waves and don't require a medium but mechanical do. So the correct answer is mechanical waves.</span>
