How do you work out a formula for a in terms of b when a is inversely proportional to b?
a = k/b when a is inversely proportional to b, where k is a constant.
What is the direct variation formula?
a is directly proportinal or inversely proportional to b
How does the proportional change in the dimensions affect the area of a polygon?
Change in area = (change in sides)2
Is the formula for finding the area of an oval the same as the formula for finding the area of a circle?
No because the formula for finding the area of an oval, which is an ellipse, is quite different
As the radius of a sphere gets larger which of the spheres measurements increases more the surface area or the volume?
The volume increases faster. (proportional to the cube of the radius)The surface area increases slower. (proportional to the square of the radius)
What is the formula relating pressuer force and area?
The formula relating pressure, force, and area is: Pressure = Force / Area. This formula shows that pressure is directly proportional to force and inversely proportional to the area over which the force is distributed.
Does the pressure increase if you increase the force or area?
If you increase the force applied to a given area, the pressure will increase. Conversely, if you increase the area over which a force is applied, the pressure will decrease. This is because pressure is directly proportional to force and inversely proportional to area according to the formula pressure = force/area.
What is the relationship between thrust and pressure?
thrust and pressure are dirrectly proportional 2 each other frm d formula pressure =perpendicular force /area
How does the resistance of a wire depend on its dimensions?
The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area. This means that for a given material, a longer wire will have higher resistance and a thicker wire will have lower resistance. The relationship is described by the formula: Resistance = resistivity x (length / cross-sectional area).
What will be the impact on the pressure if area is doubled?
If the area is doubled while the force remains constant, the pressure will be halved. This is because pressure is inversely proportional to area according to the formula P = F/A, where P is pressure, F is force, and A is area. Thus, increasing the area will decrease the pressure.
Is the resistance of the wire directly or inversely proportional to the cross-sectional area of the wire?
The resistance of a wire is inversely proportional to the cross-sectional area of the wire. This means that as the cross-sectional area of the wire increases, the resistance decreases, and vice versa.
How do you work out a formula for a in terms of b when a is inversely proportional to b?
a = k/b when a is inversely proportional to b, where k is a constant.
What is a fixed area of a rectangle?
A fixed area of a rectangle is an area that doesn't change. An area is a quantity that measures the space of a shape.Consider this example:A = length x width, which is the formula of a rectangleIf A is fixed, then it depends on what values length and width are. Then, length is indirectly proportional to width in order for A to remain fixed.
Why does the volume quadruple when the radius of a cylinder is doubled?
The volume is Base x height; the Base area is the same as the formula for a circle - which is proportional to the square of the radius. For example, if you double the radius (or the diameter, or the circumference) of a circle, its area will quadruple.
What is the direct variation formula?
a is directly proportinal or inversely proportional to b
What is a fixed jurisdictional area?
A fixed area of a rectangle is an area that doesn't change. An area is a quantity that measures the space of a shape.Consider this example:A = length x width, which is the formula of a rectangleIf A is fixed, then it depends on what values length and width are. Then, length is indirectly proportional to width in order for A to remain fixed.
How does the pressure gets affected when the force is doubled and area is constant?
When force is doubled and area is constant, the pressure will also double. This is because pressure is directly proportional to force when the area is constant, as described by the formula pressure = force/area. So, when force is doubled, the pressure exerted will also double.
