Answer:
initial velocity=2.4m/s
Explanation:
Using the formula:
v=u+at
v= final velocity (6m/s)
u=initial velocity (???)
a=acceleration (0.2 m/s²)
t=time(18 seconds)
v=u+at
6=u+(0.2*18)
6=u+3.6
u=6-3.6
u (initial velocity)=2.4m/s
The current through a resistor is
<u> (voltage across the resistor) / (resistance of the resistor)</u> .
If the numerator and the denominator of that fraction are both
multiplied or divided by the same number, then the value of the
fraction <em>doesn't change</em>.
Answer:
The flowers adapted to environmental conditions.

Answer:
gathered by using measurement tools and math
Explanation:
Quantitative data is often gathered by using measurement tools and math.
A quantitative data set is assigned values and numbers in order to solve a problem or for the purpose of a study.
- Each data set has a unique numerical value and can be counted.
- Qualitative data set does not use numerals and numbers.
- It engages the senses to make some scientific deductions.
- Examples are measurement of volume, distance, length, time, number of moles e.t.c
- Qualitative data sets include taste, smell, color e.t.c
As the wave length increases the energy of the wave decreases as the equation that relates the c=λυ λ is the wave length and υ is the frequency (which is directly proportional to the energy).
In the wave length spectrum, x-ray has a shorter wave length, meaning that
x-ray has a higher energy than ultraviolet waves.
Hope this helps.
