The quantity of iron in your blood is the dependent variable because it is influenced by how much spinach you consume. The amount of spinach you consume will act as the independent variable because it doesn't require iron in any way.
What is the dependent variable?A dependent variable is one whose values can be determined by testing in a scientific experiment. It is clear that the dependent variable depends on the independent variable. While a result, we can now see and note changes in the dependent variable as the experimenter modifies the independent variable.
Given:
Increase the amount of spinach you eat, then you will increase the iron in your blood,
Write the equation for the above phrase as shown below,
The amount of iron = variable × the amount of spinach
y = ax
here, y is The amount of iron and x is the amount of spinach
Thus, the dependent variable is the quantity of iron.

What is the difference between Mass and Weight?
Answer: Mass is the quantity of matter in an object whereas weight is the force of gravity on an object.
Weight is dependent on gravity while mass is independent on gravity
Explanation:
Jasmine is investigating the effect force has on the motion of an object. She predicts if she puts a strong force on pushing a bowling ball, it will travel a farther distance than when a weak force is applied. Is her prediction correct? No, a weak or a strong force applied to the ball is unable to affect the motion of the ball. No, the force applied to the bowling ball should be a strong force. Yes, the force applied to the bowling ball affects the motion of the ball. Yes, the ball will travel a longer distance when a weak force is applied.
Answer:
I would like to attach options to the question above for clarity.
Jasmine is investigating the effect force has on the motion of an object. She predicts if she puts a strong force on pushing a bowling ball, it will travel a farther distance than when a weak force is applied. Is her prediction correct?
A. No, a weak or a strong force applied to the ball is unable to affect the motion of the ball.
B. No, the force applied to the bowling ball should be a strong force.
C. Yes, the force applied to the bowling ball affects the motion of the ball.
D. Yes, the ball will travel a longer distance when a weak force is applied.
The correct option is C (Yes, the force applied to the bowling ball affects the motion of the ball).
Explanation:
First, a force is any effort either push or pull that causes an object to undergo a change.
A bowling ball can remain at rest or in motion except a force acts on it. This brings us to the question above, the mass which affects force is not mentioned which means it is uniform or negligible. Recall that force = mass X acceleration. So the greater the force that is applied to the bowling ball the further distance it will travel. From the question, she applied a forward force (pushing), so the more force she applies the further the bowling ball will travel.

A child easily pushes an empty shopping cart around the store. As the cart fills, the child has to exert more force to keep the shopping moving and keep up with his mom. Which law is best supported by this example?
A. Newton's First Law
B. Newton's Second Law
C. Newton's Third Law
D. The law of definite proportions
Answer:
B Newton's second law
Explanation:
An empty grocery cart is easier to move because there is less mass in an empty cart compared to a full cart. Newton's second law state that an object's acceleration depends on the mass of the object and the force applied.
what are the steps to form a igneous rock
Answer:
igneous rocks are formed through the cooling and solidification of magma or lava. As hot, molten rock rises to the surface, it undergoes changes in temperature and pressure that cause it to cool, solidify, and crystallize.

Which of the following is a property of an ionic compound?
A
has a low boiling point
B
forms molecules
C
is soft and flexible
D
conducts electricity when aqueous
Answer:
D
Explanation:
ionic compounds conduct electricity when molten or dissolved in water. ionic compounds conduct electricity when dissolved in water because water molecules are attracted to ions, this weakens the strong electrostatic forces of attraction between the oppositely charged ions. thus, ions are pulled away from the lattice structure and the remaining compound dissolves in water to form aqueous solution. The presence of free moving ions enables the ionic compound to conduct electricity.

. Calculate the equivalent resistance of the circuit.
c. Calculate the current through the battery.
d. How much current is passing through each resistor
[tex]\huge{ \mathfrak{ \underline{ Answer} \: \: ✓ }}[/tex]
1. Calculate the equivalent resistance in the circuit :
In the given diagram, the resistors are in series connection,
So equivalent resistance = sum of resistance of both resistors.
[tex] \large \boxed{R_{eq} =R_1 +R_2 }[/tex]
[tex]R_{eq} = 480 + 360[/tex][tex]R_{eq} = 840 \: ohms[/tex]Therefore, Equivalent resistance = 840 ohms.
2. Calculate the current through the battery :
[tex] \boxed{ \mathrm{current = \dfrac{potential \: \: difference}{resistance} }}[/tex]
[tex]i = \dfrac{120}{840} [/tex][tex]i = \dfrac{1}{7} [/tex][tex]i = 0.142 \: Amperes[/tex]Hence, current through the battery = 0.142 A
3. How much current is passing through each resistor :
Since the resistors are joined in series connection, the current flowing through each resistor will be equal = 0.142 Amperes.

Explanation:
An upright object 2.80 cm tall is placed 16.0 cm away from the vertex of a concave mirror with a center of curvature of 24.0 cm. What is the focal length of this mirror?
Answer:
f = 12 cm
Explanation:
Center of Curvature:
The center of that hollow sphere, whose part is the spherical mirror, is known as the ‘Center of Curvature’ of mirror.
The Radius of Curvature:
The radius of that hollow sphere, whose part is the spherical mirror, is known as the ‘Radius of Curvature’ of mirror. It is the distance from pole to the center of curvature.
Focal Length:
The distance between principal focus and pole is called ‘Focal Length’. It is denoted by ‘F’.
The focal length of the spherical (concave) mirror is approximately equal to half of the radius of curvature:
[tex]f = \frac{R}{2}[/tex]
where,
f = focal length = ?
R = Radius of curvature = 24 cm
Therefore,
[tex]f = \frac{24\ cm}{2}[/tex]
f = 12 cm
An empty water tank has a rectangular base with side lengths of 1.2 m and 2.3 m. The weight of the tank applies a pressure of 350 Pa to the surface it is resting on. What is the weight of the tank?
Answer:
Weight = 966 Newton.
Explanation:
Given the following data;
Length = 1.2 m
Width = 2.3 m
Pressure = 350 Pa
To find the weight of the tank;
We know that weight is the force of gravity acting on an object multiplied by its mass.
Weight = mg = force
Hence, we would determine the force using the parameters that were given.
But we would first determine the area of the rectangular tank.
Area of rectangle, A = length * width
A = 1.2 * 2.3
A = 2.76 m²
Mathematically, pressure is given by the formula;
Pressure = force/area
Force = pressure * area
Substituting into the formula, we have;
Force = 2.76 * 350
Force = 966 Newton
Therefore, the weight of the tank is 966 Newton.
