Answer:
t = 1.75
t = 0.04
Explanation:
a)
For part 1 we want to use a kenamatic equation with constant acceleration:
X = 1/2*a*t^2
isolate time
t = sqrt(2X / a)
Plugin known variables. Acceleration is the force of gravity which is 9.8 m/s^2
t = sqrt(2*15m / 9.8m/s^2)
t = 1.75 s
b)
The speed of sound travels at a constant speed therefore we don't need acceleration and can use the equation:
v = d / t
isolate time
t = d / v
plug in known variables
t = 15m / 340m/s
t = 0.04 s
<span>ATP is required for both light-dependent and light-independent reactions.
ATP stands for </span> adenosine triphosphate.
Hope this helps ;)
Explanation:
1.
the rate at which something occurs over a particular period of time or in a given sample.
"an increase in the frequency of accidents due to increased overtime"
2.
the rate per second of a vibration constituting a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light).
"different thicknesses of glass will absorb different frequencies of sound"
Answer:
by using problem solving skills they could solve who,what,where did the crime oriented. and using critical thinking is good for you to get the job done!

Answer:
Weight = 137.2 kg.m/
Explanation:
Given
mass of an object, m = 14 kg
Weight (W) is given by the formula:
W = mg , where m is mass of the object and g is acceleration due to gravity and the value is 9.8 m/
Hence W = 14 kg x 9.8 m/
= 137.2 kg.m/
