As you said p=w/t.
but, w=f×s
=500×5=2500j
t=10s
p=w/t
=2500/10=250 watts
Answer:
1. Nitrogen
2. Oxygen
3. Carbon dioxide
4. Water vapor
5. Ozone
Explanation:
The atmosphere composes of 78% nitrogen which occupies the largest percentage followed by oxygen which takes up 21%, Argon takes up 1% then other components such as water vapor occupy between 0-7% and ozone takes 0.0-0.01. Moreover, 0.01-0.1 is occupied by carbon dioxide. Therefore, the answers for 1-5 are as follows.
1. Nitrogen
2. Oxygen
3. Carbon dioxide
4. Water vapor
5. Ozone
Answer:
at 
Explanation:
We need to calculate the components of the resultant force on both the x (horizontal) and y (vertical) direction.
Components of the first force F1:
Components of the second force F2:
So the components of the resultant force are
So the magnitude of the resultant force is
And the direction is
The magnitude of the acceleration can be found by using Newton's second law:
while the direction is the same as the resultant force, .
First, we determine the volume of the trunk by finding
first the radius from the circumference through the equation,
<span> C
= 2πr</span>
<span> r
= C/2π</span>
Substituting the known values,
<span> r
= 4.5/2π = 0.716 m</span>
Then, we calculate for the volume through the equation,
<span> V
= πr2h</span>
<span> V
= π(0.716 m)2(8m) = 12.9 m3</span>
Multiplying the calculated value to the density will give
the mass as,
<span> Mass
= (12.9 m3)(752 kg/m3) = <span>9699.36 kg</span></span>
