An ac generator with peak voltage 100 volts is placed across a 10-? resistor. What is the average power dissipated?

Answers

Answer 1
The correct answer is: Average Power  = 500 W

Explanation:
Root-mean square voltage = Vrms = Vpeak /√2 = 100 / √2 volts
Resistance = R = 10 Ω
Average power = Pavg = (Vrms)^2 / R = (100 * 100) / (2 * 10) = 500 W

If a clock expends 2 W of power from a 1.5 V battery what amount of current is supplying the clock?

Answers

1.3 A
If a clock expends 2 W of power from a 1.5 V battery, what amount of current is supplying
the clock?
solution
as we know
p=vi
i=p/v
=2/1.5
=1.3A

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.

Which parameter of glass is measured with bromoform and bromobenzene mixtures in a column?

Answers

The answer is Density.  The Density of the glass is measured with bromoform and bromobenzene mixtures in a column.  Density measurement is done using Density gradient columns. It is a  temperature-controlled density column containing a mixture of  bromobenzene and  bromoform.

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.

Answers

Lunar solar full that is all your welcome my friend ha ha

The largest tides occur at full moon, solar eclipse, and lunar eclipse. Thus, the correct option is B, E, and F.

What are solar and lunar eclipses?

Eclipses are of two types: Solar and Lunar eclipse. A solar eclipse occurs when the moon enters between the sun and the earth, which its shadow on the earth's surface.

A lunar eclipse occurs when the earth is moved between the sun and the moon and the Earth leaves its shadow on the moon. The tides form in seas because of the gravitational force of the moon.

The gravity of the moon makes the tides or waves in the seas or oceans. The full moon has more gravitation force and hence, larger tides are formed. The largest tides are also formed by solar and lunar eclipses.

When the sun is aligned with the moon during the eclipse, the sun is also pulling in the same direction resulting in the largest tides. The gravitational pull of the sun and moon increases the tides in ocean surfaces on Earth.

Thus, the largest tides occur at Full moon, solar and lunar eclipse. The correct options are B, E, and F.

a roller coaster slows as it travels up a hill
a) speed
b) velocity
c) acceleration

Answers

think the answer should be C
Final answer:

As the roller coaster ascends the hill, it experiences a decrease in speed which affects its velocity, leading to what we describe as negative acceleration or deceleration.

Explanation:

When a roller coaster is traveling up a hill, it begins to slow down due to the force of gravity opposing its motion. This is a scenario of negative acceleration or deceleration.

Speed refers to how fast an object is moving without concerning the direction. In this case, the speed of the roller coaster decreases as it climbs the hill.

Velocity includes both the speed and direction of an object's motion. Here, the velocity also decreases as the speed decreases and the direction is upwards.

Acceleration refers to the rate of change of velocity. When the roller coaster slows down while moving up, it is undergoing negative acceleration or deceleration.

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.

Answers

The electrostatic force between two charges is given by
[tex]F=k \frac{q_1 q_2}{r^2} [/tex]
where
k is the Coulomb's constant
q1 and q2 are the two charges
r is their separation

In this problem, the two charges are identical, so we can call them q1=q2=q, and the formula becomes
[tex]F=k \frac{q^2}{r^2} [/tex]

Since we know the magnitude of the force and the separation between the two charges, we can re-arrange the equation to find the value of each charge:
[tex]q= \sqrt{ \frac{Fr^2}{k} } = \sqrt{ \frac{(6.2 \cdot 10^{-9} N)(3.7 \cdot 10^{-10}m)^2}{8.99 \cdot 10^9 Nm^2C^{-2}} }=3.07 \cdot 10^{-19} C [/tex]

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.

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

Answers

Their average speed is greater than their 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.

A. growth hormone (GH)
B. estrogen
C. norepinephrine
D. cortisol

Answers

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.

#SPJ2

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.
