Answer:
10.03 s is the time the decoy is in the air
Explanation:
From the information given we know:
- because is measured clockwise from horizontal.
- The initial speed of the decoy is the plane's speed at the moment of release
We will need to work in meters and m/s, so
The horizontal motion of a projectile is given by:
because , this becomes
We have that , solving for <em>t, </em>we have
Answer:
No .
Explanation:
The vapor pressure of water at room temperature is .0313 atom or 3.13 kPa.
To make a liquid boil, its vapor pressure must be equal to pressure around it.
So pump must create pressure of 3.13 k Pa or less to make water attain its stage of boiling at room temperature. As the motor can not produce pressure lesser than 15 k Pa , pump will not be able to make water boil at room temperature.
Explanation:
The relation between pressure and area is as follows;
Here, P is the pressure, F is the applied force and A is the area.
There is an inverse relationship between the pressure and area.
If the area is less then the pressure is more. If the area is more then the pressure is less.
It is given in the problem that It is much easier to slice a piece of pie with the edge of a sharp knife than with the edge of a pencil. The area of the edge of a pencil is more than the area of the edge of the knife. Then, less pressure is applied in case of using the edge of the pencil.
More force is required to cut the slice of pie by using pencil.
90t - .100 = 75t
90t - 75t = 0.100
15t = 0.100
t = 0.0067
<u>t = 0.0067 hours or 24.12 seconds</u> (.0067 * 60 minutes * 60 seconds)
Yes Flourine is the most active
