Opening the valve allows more of the pressurized material out. If the area is decreased, less of the pressurized material is released, and its force ends up more spread out, reducing the pressure. Opening the valve will increase volume of transfer of your liquid.
Answer:
<em>The actual dimensions of the classroom are 50 cm x 70 cm</em>
Explanation:
<u>Scaling
</u>
When we need to represent real-world dimensions into small spaces, we use scaling. Distance scaling tells us what is the equivalence between the real units and the scaled units. In this case, we are told that 10 cm is equivalent to 1 meter. As 1 meter is 100 cm, it means that the scale is 100/10=10. Thus, each centimeter in the paper is equivalent to 10 cm in the real distance.
The classroom is 5 cm x 7 centimeters. Scaling back to the real values, the classroom has measures of 50 cm x 70 cm.
What are you exactly asking for? A solution that feels slippery? That could mean anything. Please explain a little bit more.
The focal length of the converging lens based on the arrow placed 3 centimeters to the left and the imaged formed 3 cm to the right is 1.5 cm.
<h3>
Focal length of the converging lens</h3>
The focal length of the converging lens is determined by applying the following converging lens formula.
1/f = 1/v + 1/u
where;
- v is the image distance = 3 cm
- u is the object distance = 3 cm
- f is the focal length = ?
1/f = 1/3 + 1/3
1/f = 2/3
f = 3/2
f = 1.5 cm
Thus, the focal length of the converging lens is 1.5 cm.
