a. **capacitance** of circuit is** C= 0.849** micro farad & b. time constant of the circuit is **t=2.89 sec. **

A component or circuit's **capacitance **is its capacity to accumulate and store electrical charge as a type of energy. Energy-storing devices known as capacitors come in a variety of sizes and forms. A property of an electric conductor, or group of conductors, known as capacitance is determined by how much separated electric charge can be held on it for each unit change in electrical potential. A store of electrical energy is also implied by capacitance. A **potential difference** between two initially uncharged conductors is created if electrical charge is transferred between them, causing both to become equally charged (one positively, the other negatively). The capacitance C is defined as the product of the charge density q on each conductor and the **potential difference** V between them, or C = q/V. Only if the charge is kept constant will capacitance drop as potential increases. Less **potential difference** equals higher capacitance, according to the equation.

The **acceleration **of the dolly-sandbag system is **0.29 m/s².**

The definition of **force **in physics is: The push or pull on a massed object changes its velocity. An **external force** is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude.

A spring balance can be used to calculate the **Force**. The Newton is the SI unit of **force**.

Given parameters:

Any action that seeks to preserve, modify, or deform a body's motion is considered to be a **force **in mechanics. Usually, Isaac Newton's three laws of motion from his Principia Mathematica are used to describe the concept of force (1687). A body at rest or moving uniformly in a straight path will stay in that state unless a force is applied to it, according to Newton's first law. According to the second law, any external force that interacts with a body causes it to **accelerate **(change its velocity) in the force's direction. A vector quantity, force is one that has both magnitude and direction. The rate at which an item changes its velocity is known as the vector quantity known as **acceleration**. When an object's velocity changes, it is said to be accelerating. On occasion, sports broadcasters will suggest that a person is accelerating if they are travelling quickly. **Acceleration**, however, has little to do with speed. Even though a person is travelling quickly, they may not be accelerating. A change in an object's speed is referred to as acceleration.

The ratio of the heads of **Arkansas **reservoir to west virginia's reservoir is **1813: 1120.**

Consider the **West Virginia reservoir**

To calculate the head of the Virginia reservoir, we will use

**φ = P / nρgh **

where φ is the flow rate, P is the power generated, n is efficiency, ρ is the density of water, g is the acceleration due to gravity, and h is the head.

Given that the flow rate is 7 m/s, the power generated is 12 MW, and 80% is the efficiency.

We know that the density of water is 1000 kg/m³ and acceleration due to gravity is 9.8 m/s²

By using equation 1:

**h = P / φnρg**

h = 9/3*80/100*1000*9.8

h = 13440

Similarly, the head of the Arkansas reservoir will be

Given that the** flow rate** is 3 m/s, the power generated is 9 MW, and 74% is the efficiency.

h = P / φnρg

h = 9/3*74/100*1000*9.8

h = 21756

Now, the ratio of the heads of Arkansas reservoir to west virginia's reservoir is:

A singly charged positive ion has a** **mass of 3.3x10-26 kg. after being accelerated from rest through a** potential difference** of 933 v, the ion enters a magnetic field of 1.43 t along a direction perpendicular to the field. The** **radius of the circular path of the ion in the field is (r)= 1.982 cm.

Energy is a term that means the object is affected by some amount of force and move a distance. That is called the **energy**. It can be measured in Joule.

To calculate the radius we are using the formula here,

r= mu/Bq

Where we are given,

m = The mass of single positive charged ion.= 3.3×10⁻²⁶kg.

q= The charge of the single positive charged ion.= 1.602×10⁻¹⁹ C

B = The magnetic field for the electric field. = 0.92 T

But we don't know the term, u= the velocity of the single positive charged ion.

So we have to calculate the velocity of the single positive charged ion. To calculate the velocity we are using the formula,

(1/2)mu²=qv

Here we are given,

v= The potential difference of the electric field. = 933v.

We have to calculate the velocity=u, as Conservation of energy we know,

(1/2)mu²=qv

Or,(1/2)mu²=ev

Or, u²= (2×1.602×10⁻¹⁹×933)/(3.3×10⁻²⁶)

Or, u=91325.9 m/s.

So from this we know the velocity of the ion, u=91325.9 m/s.

Now, we have to calculate the radius in a magnetic field= r,

r= mu/Bq =mu/Be

Or, r= 3.3×10⁻²⁶×91325.9/0.92×1.602×10⁻¹⁹

Or, r=0.01982m

Or, r=1.982 cm.

Next, the element perpendicular to this inclination surface for this black block. This part is B G Costs 57.7° and a component along the spring-bound incline of mbG sign 57.7° The blocks are shown to be travelling with an acceleration of A in the direction of the left.

Given to us are MB square markings traveling at 1.5 meters per second. The bulk of this white blog weighs 3.19 kilograms. It is absent. We need to locate it. First, as the white vlog is moving down, use the free body diagram of the white block. Therefore, M W G sign 57.7 **degrees **force will be more than that tension T for this white block. Thus, using Newton's second rule of motion, the net force will be equal to.

The block's mass times its acceleration equals the block's net force. Using a free body schematic of the ascending black bloc, continue. T will therefore be more for it. Therefore, this equals p – Mbg. indication of 57.7 **degrees**. Using Newton's second rule of motion, which is equal to M B A, once more This is equation #1, that was equation #1, this is equation #2, this is one, and this is equation #3. hence, adding 1 and 2. It is obvious that the tension will end and that G signed 57.7° will be seen as an exit signal.

A frog leaps from flat ground at 6.32 m/s

at a 36.3 angle. What maximum height

does it reach?

(Unit = s)

At hmax, Vy=0

vy=v0y-gt

0=6.32sin(36.3)-9.81t

t=.381 seconds

Δy=v0yt-.5gt^2

Δy=6.32sin(36.3)*.381-.5(9.81)(.381)^2

In a constant-pressure calorimeter of negligible heat capacity, 25 ml of 1. 00 m cacl2 is mixed with 25 ml of 2. 00 m kf, resulting in solid caf2 precipitating out of the solution. During this process, the temperature of the water rises from 25. 0c to 26. 7c. Assume the specific heat capacity of the solution is 4. 184 j/cg and the density of the solution is 1. 00 g/ml. Calculate the enthalpy of precipitation in kj per mole of caf2 precipitated.
