Answer:
independent variable is found on the x axis while dependent variable is found on the y axis
Answer is the highest temperature, so D
Higher temperatures allow for sound to move faster, since the molecules vibrate faster, sound waves can travel more quickly. The speed of sound in room temperature air is 346 meters per second. This is faster than 331 meters per second, which is the speed of sound in air at freezing temperatures.
Neat little fact: This is also why in the winter when there is snow on the ground, it seems more peaceful and quite. The snow absorbs the sound waves and the temperature makes them not travel as fast, getting more quite as they go.
Answer:
r2 = 2.401557 cm
distance = 0.10 cm
Explanation:
given data
radius = 2.50 cm
density = 15.0 nC/m
voltmeter read = 175
solution
we know here potential difference that is express as
ΔV =
...........1
so here
as here
is linear charge density
r2 = r1 ×
r2 = 2.40 ×
r2 = 2.401557 cm
and
here distance above surface will be
distance = r1 - r2
distance = 2.50 - 2.40
distance = 0.10 cm
Answer:
The protons and the neutron are located in the nucleus and the electrons is the outermost region
Answer:
Work done, W = 10195.92 Joules
Explanation:
Given that,
Mass of the crate, m = 170 kg
Distance, d = 10.2 m
The coefficient of friction, 
Let W is the work done by the mover. It is given by in terms of coefficient of friction as :


W = 10195.92 Joules
So, the work done by the mover is 10195.92 Joules. Hence, this is the required solution.
