Answer:
20 m/s
Explanation:
initial velocity, u= 25m/s
u has two components. one in horizontal and in one vertical.
so,
u sin theta = vertical component.
=> u sin theta = 25× 4/5
= 20 m/s
In 4.5 billion years, the amount of mass lost is 1.41912 * 10¹⁷ kg.
<h3>
Equation</h3>
An equation is an expression used to show the relationship between two or more variables and numbers.
Given that:
Io loses about a ton (1000 kilograms) of sulfur dioxide per second to Jupiter's magnetosphere.
In 4.5 billion years, amount of mass lost = 1000 kg/s * (4.5 * 10⁹ * 365 * 60 60 * 24) = 1.41912 * 10¹⁷ kg.
In 4.5 billion years, the amount of mass lost is 1.41912 * 10¹⁷ kg.

Answer: when the wave encounters something, it can bounce (reflection) or be bent (refraction). In fact, you can "trap" waves by making them bounce back and forth between two or more surfaces. Musical instruments take advantage of this; they produce pitches by trapping sound waves.
Explanation: Any bunch of sound waves will produce some sort of noise. But to be a tone - a sound with a particular pitch - a group of sound waves has to be very regular, all exactly the same distance apart. That's why we can talk about the frequency and wavelength of tones.
