Answer:
Option D
A type I error is making the mistake of rejecting the null hypothesis when it is actually false.
Explanation:
Error type I is usually represented by alpha symbol and type I error entail making a mistake of rejecting the null hypothesis when it's actually true. Type II error on the other side involves making a mistake of failing to reject null hypothesis when it is actually false. The statement in option D is false because it contradicts the definition of type I error above hence the only false statement in relation to hypothesis testing is option D, A type I error is making the mistake of rejecting the null hypothesis when it is actually false.
Answer:
Explanation:
Given
Velocity of bat
Frequency of sound
velocity of sound
using Doppler Effect apparent frequency is given by
where
apparent frequency
v=velocity of sound in the given media
velocity of source
velocity of observer
here velocity of source is zero
as source is travelling towards source thus
<span>An object keeps the same amount of kinetic energy unless it speeds up or slows down.
Kinetic energy can be calculated for any moving object as long as the objects' mass and speed are known.
The unit used when measuring kinetic energy is called a joule.
Kinetic energy can occur in any direction whether up and down or left to right.
<span>
When an objects' mass doubles, its kinetic energy also doubles.</span></span>
Answer:
That insane it might be true because a planet sometimes quoted to be an Earth 2.0 or Earth's Cousin based on its characteristics; also known by its Kepler Object of Interest designation KOI-7016.01) is an exoplanet orbiting the Sun-like star Kepler-452 about 1,402 light-years (430 pc) from Earth in the constellation Cygnus.
