Hi there!
The formula for velocity given acceleration:
v = at
Plug in given values:
v = 6.4(7) = 44.8 m/s
Answer:
You should generally have one independent variable in an experiment. This is because it is the variable you are changing in order to observe the effects it has on the other variables.
HOPE THIS HELPED!!!!!!!!!!!!XDDDDDDDDD
Answer:
centripetal force
Explanation:
When a person spins a bucket of water in a circle, the force acting on the bucket to keep the water inside is called centripetal force.
The centripetal force is a constant resultant force that acts on an object in circular motion.
I believe it's 'A'. Hopefully this helps!~ :)
When I went through with the math, the answer I came upon was:
<span>6.67 X 10^14 </span>
<span>Here is how I did it: First of all we need to know the equation. </span>
<span>c=nu X lamda </span>
<span>(speed of light) = (frequency)(wavelength) </span>
<span>(3.0 X 10^8 m/s) = (frequency)(450nm) </span>
<span>We want the answer in meters so we need to convert 450nm to meters. </span>
<span>450nm= 4.5 X 10^ -7 m </span>
<span>(3.0 X 10^8 m/s) = (frequency)(4.5 X 10^ -7 m) </span>
<span>Divide the speed of light by the wavelength. </span>
<span>(3.0 X 10^8m/s) / (4.5 X 10^ -7m) =6.67 X 10^ 14 per second or s- </span>
<span>Answer: 6.67 X 10^14 s- hope this helps</span>
