Two identical positive charges exert a repulsive force of 6.2 × 10−9 n when separated by a distance 3.7 × 10−10 m. calculate the charge of each. the coulomb constant is 8.98755 × 109 n · m2 /c 2 . answer in units of
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.
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.
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.

Elements are arranged in the periodic table based on various patterns. For example, the element magnesium (Mg) A. has a higher atomic mass than the element sodium (Na). B. has a lower atomic mass than the element beryllium (Be). C. has a higher atomic mass than the element calcium (Ca). D. all of these
Answer:
A has a higher atomic mass than the element sodium (Na).
Explanation:
Just did the study island :)
Elements are arranged in the periodic table based on various patterns. For example, the element magnesium (Mg) A. has a higher atomic mass than the element sodium (Na). Option A is correct.
What is periodic table ?The periodic table is an organization of all known elements in order of increasing atomic number and repeating chemical characteristics.
They are organized in a tabular format, with a row representing an era and a column representing a group.
Elements are ordered in increasing atomic number order from left to right and top to bottom.
Elements of the same group will have the same valence electron configuration and, as a result, will have comparable chemical characteristics.
Elements are arranged in the periodic table based on various patterns. For example the element magnesium (Mg) A. has a higher atomic mass than the element sodium (Na).
Hence, option A is correct.

Which term refers to the difference between the energy of the transition state and the energy of the reactamts?
The transition state is the state where an electron makes a jump to change its energy level. The term refers to the difference between the energy of the transition state and the energy of the reactants is the activation energy.
What is energy?Energy is the ability to do work.
The transition state is considered to be the highest energy point on the minimum free energy reaction path (MERP). It is the state corresponding to the highest potential energy along the reaction.
Reactions occur between the path of converting reactants to products which is of lowest energy.
Thus, the term refers to the difference between the energy of the transition state and the energy of the reactants is the activation energy.

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.

Find the acceleration of a automobile whose speed increases from 10 m/s to 22 m/s in 8 seconds.
Jake and brenda drove at a speed of 30 miles for one hour then they turned around and drove 45 miles per hour until they were back where they started what is the true or what is true about their average speed and average velocity
Answer:
Average speed is greater than average velocity. Average velocity is zero.
Explanation:
Average speed is calculated by:
[tex]\text{Average speed} =\frac{\text {Total Distance}}{\text{Total time taken}}[/tex]
Distance is the length of the total path traveled.
Average velocity is given by:
[tex]\text{Average velocity} =\frac{\text {Total Displacement}}{\text{Total time taken}}[/tex]
Displacement = final position - initial position.
Since, final position =initial position, Displacement = 0, therefore, average velocity = 0
It can be concluded that average velocity is zero and average speed is greater than average velocity.
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]
Hence we can conclude that the amount of current supplied to the clock is 1.34 A.

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.
