In a four stroke engine, the piston compresses the gas mixture during the ______ stroke.
Answer : Compression / Power
Explanation : In a four stroke engine, the piston compresses the gas mixture during the power / compression stroke.
In the second stage of compression stroke, the stroke begins at bottom dead center, or just at the end of the suction stroke, and ends at top dead center.
In this type of stroke, the piston usually compresses the air-fuel mixture in preparation for ignition during the power stroke.

An individual having difficulty with high blood pressure may be experiencing an imbalance in all of the following hormones except __________.
A. growth hormone (GH)
B. estrogen
C. norepinephrine
D. cortisol
The answer is; B
The fluctuation of estrogen in the body is common and its function in a cycle helps regulate the menstrual cycle in females. Therefore, its imbalance is not associated with blood pressure.
Growth hormone affects the renin-angiotensin system that influences blood fluid levels hence affects blood pressure. Norepinephrine is a neurotransmitter that affects dilation and vasoconstriction of blood vessels and the hearts rate hence affects blood pressure. Cortisol is a stress hormone and its increase in the body increases blood pressure. Cortisol is only produced in periods of stress and should not be produced in prolonged periods. Its imbalance, therefore, affects blood pressure.
the other answer is right, the right option is B. estrogen.

Which parameter of glass is measured with bromoform and bromobenzene mixtures in a column?
Answer: Density
Explanation:
Density is the parameter which is used for comparision of two doubted to be similar pieces of the glasses in the columns where a specific volume of liquids bromoform and bromobenzene are used. The two glasswares (graduated cylinders) are used in this process along with the liquids. The level at which the glass pieces in the column settles that represent their density. If two pieces of glass are from same source then they will settle at the same level in the column. This method is known as density gradient method.
If a clock expends 2 W of power from a 1.5 V battery what amount of current is supplying the clock?
The power generated at the clock is dependent on the voltage and current supplied to the clock. The amount of current supplied to the clock is 1.34 A.
What is power?Power can be defined as the amount of energy transferred per unit time interval within a system.
Given that the voltage V is 1.5 V and power P generated at the clock is 2 W.
The power generated at the clock is given by the formula,
[tex]P = VI[/tex]
[tex]2 = 1.5 \times I[/tex]
[tex]I = 1.34 \;\rm A[/tex]

c.
Use Coulomb's Law formula to calculate the charge of each identical positive charge given the force and distance. Each charge is 4.0 × 10^-19 C.
We can use Coulomb's Law formula: F = k * (q^2) / r^2, where F is the force, k is the Coulomb constant, q is the charge, and r is the distance between the charges.
Given: F = 6.2 × 10^-9 N, r = 3.7 × 10^-10 m, and k = 8.98755 × 10^9 N · m^2 /C^2. Plugging these values into the formula, we get q = √(F * r^2 / k).
Calculating: q = √(6.2 × 10^-9 * (3.7 × 10^-10)^2 / 8.98755 × 10^9) = 4.0 × 10^-19 C.
Therefore, each charge is 4.0 × 10^-19 C.

The term referring to the difference between the energy of the transition state and the energy of the reactants is activation energy.
The term you're looking for is activation energy, which is the energy required to transform the reactants into the transition state. This can also be considered the 'energy barrier' that must be overcome for a reaction to proceed. The transition state, also known as an 'activated complex', is the highest energy point during the process of bonds breaking and forming. The magnitude of the activation energy is crucial because it determines the kinetics of a reaction; the higher the energy barrier, the slower the reaction rate. Moreover, the existence of a catalyst in a reaction can lower the activation energy, thereby increasing the reaction rate without altering the energies of the reactants or products.

A. The magnetic field strength would increase
B. The magnetic field would not be affected by this change
C. The magnetic field strength would decrease
D. The magnetic field would change direction more frequently
The magnetic field strength is directly proportional to the current through the circuit. When the voltage is increased, current also increases, results in a rise in magnetic field strength. Thus, option A is correct.
What is magnetic field?A magnetic field is the field produced by the magnetic flux or field lines with a magnitude and direction. A magnetic field is always associated with an electric field where, the magnitudes of both field are in direct proportion.
The magnetic field lines will be perpendicular to the electric flux. According to Ohm's law, voltage and current through a circuit are directly proportional to each other.
As the voltage in a circuit is increased, the current through it increases which n turn result in a hike in magnetic field strength. Therefore, when 1.5 volt is changed by 9 volt battery in the circuit, magnetic field strength would increase.
