A decagram is 1000 times bigger than a centigram
Answer:
Width of sound beam is 7.557 m
Explanation:
First we will calculate the wave length from given data:
λ=v/f
Were:
v is the speed
f is the frequency

We considered the opening long and narrow, Using single slit diffraction formula:
mλ=dsinΘ
where:
d is the crack width
m is the order
Θ is angle
Considering m=1, The angle between first minimum from center of beam is:

The width of beam is:
tanΘ=y/L

Width=7.557 m
All of them have a negative effect on the environment.
But your answer would be Natural Gas being the leading source of energy in the US by 31% overall.
Hey there!
A sound wave is a<u> longitudinal wave</u>, meaning that the motion of the particles of the wave is parallel to the direction of the motion of the wave.

The acceleration of the object if the net force is decreased = 0.13 m/s²
<h3>Further explanation</h3>
Given
A net force of 0.8 N acting on a 1.5-kg mass.
The net force is decreased to 0.2 N
Required
The acceleration of the object if the net force is decreased
Solution
Newton's 2nd law :

The mass used in state 1 and 2 remains the same, at 1.5 kg
ΣF=0.8 N
m=1.5 kg
The acceleration, a:

ΣF=0.2 N
m=1.5 kg
The acceleration, a:
