Answer:
Carbon 12
Explanation:
I don't 100% know what to put here, but...
When you remove the nucleus from an oxygen atom, almost everything of the base oxygen is essentially stripped away. Since almost everything is made of carbon, and Carbon 12 is one of the most common forms of Carbon, Carbon 12 would be what is left.
Answer:
tbh vector does not have any direction at all the answer is 0
Answer:
The belt ramp is moving at 0.047 m/s
Explanation:
Hi!
The equation for the position of an object moving in a straight line with a constant acceleration is:
x = x0 + v0 * t + 1/2 * a * t²
where:
x = position at time "t"
x0 = initial position
v0 = initial velocity
t = time
a = acceleration
If the object moves with constant speed, then, a = 0 and x = x0 + v * t
First, let´s find the lenght of the speed ramp by calculating the distance walked by Clifford.
x = x0 + v0 * t +1/2 * a * t²
x0 = 0 placing the origin of our reference system at the begining of the ramp
v0 = 0 Clifford starts from rest
t = 64 s / 4
a = 0.37 m/s²
Then:
x = 1/2 * 0.37 m/s² * 16 s = 3.0 m
Now that we know the lenght of the speed ramp, we can calculate the speed of the ramp which is constant:
x = x0 + v * t x0 = 0
x = v * t
x/t = v
<u>3.0 m / 64 s = 0.047 m/s</u>
Answer:
14523.55J
Explanation:
The work done by the jogger against gravity is given by the following equation;
where m is the mass, g is acceleration due to gravity taken as and h is the height of the hill.
Since the length of the hill is 132m and it is inclined at 12 degrees to the horizontal, the height is thus given as follows;
Substituting this into equation (1) with all other necessary parameters, we obtain the following;
