Answer:
a)188.65m
b)154.35m
c)243.7m
Explanation:
Given data:
(a) The distance from the kicker to each of the 2 spectators is given by:
where,
v= speed of sound
=time taken for the sound waves to reach the ears
m
(b)
where,
v= speed of sound
=time taken for the sound waves to reach the ears
(c)As the angle b/w slight lines from the two spectators to the player is right angle,
hypotenuse=the distance b/w 2 spectators
and, the slight lines are the other 2 lines
The answer to this question is letter C) Each student read
the meter stick from different angles.
The students might have been reading the meter stick facing
each other. So when one reads the meter stick as 18, the other student will
read the reverse image of the measurement. 18 and 82 can be easily mistaken
when reversed.
Answer:
Amplitude
Explanation:
The lower the amplitude, the lower the frequency.
Answer:
Hey there
I will give you the correct answer based on Wikipedia timelines.
You are correct (Copernicus, Brahe, Kepler, Newton)
Nicolaus Copernicus: 19 February 1473 – 24 May 1543.
Tyco Brahe: 14 December 1546 – 24 October 1601.
Johannes Kepler: 27 December 1571 – 15 November 1630.
I
Issac Newton: 4 January 1643 – 31 March 1727.
Brainly is GREATLY appreciated. it took me 30 minutes to get all the timelines!!!
Renewable resources:
A renewable resource is one that can be used repeatedly and does not run out because it is naturally replaced.
Nonrenewable resource:
A nonrenewable resource is a natural substance that is not replenished with the speed at which it is consumed. It is a finite resource.
Thenks and pls mark me brainliestt :))
