The values obtained for R and E1 after solving the given circuit will be equal to 1 ohm and 38 V.

Charged material experiences a force when exposed to an electromagnetic field because of the fundamental characteristic of electric charge. It's conceivable for electrical ions to be positive or negative. Two charges that are opposed to one another repel one another.

As per the given data in the question,

Vp= 26V and,

E₂ = 24V

V₂ = 26-24

= 2V

Given, R will lose 345.6KJ of energy in a day.

We must determine the energy wasted by R in 1 second in order to determine the power dissipated across R.

So,

PR = (345.6x103)J / (24x3600)sec

= 4 Watts

Also,

PR = I₂ x R

4 = I₂R          (1)

V₂ = Voltage across R = 2V

2 = I x R

I = 2/R          (2)

Substitute equation (2) in equation (1) we get

4 = 4/R

R = 1 ohm.

I = 2 ampere

Six ohms of resistance will not block the same current. So,

V₁ = 2X6

= 12 Volts

So,

Now, Apply KVL in the circuit,

E₁ = V₁ + Vp

= 12 + 26

E₁ = 38 V

Answer: its c

Explanation:

Measure of Restitution When the velocity vectors of two objects are parallel, direct collisions between them happen. While energy is lost during the impact when one or both of the objects are bent.

v 2−v 1=−e(u 2−u 1). This equation represents Newton's law of restitution. The restitution coefficient always meets the condition 0e1. The balls stay in contact with one another after a collision when e=0.

It is crucial to understand the coefficient of restitution since it establishes whether a collision is elastic or inelastic in nature. Whether a collision is elastic or not reveals whether there is any kind of kinetic energy loss as a result of the impact.

Z = -0.675

From here we use the formula for z score

X = z(sd) + u

Electronic rack-and-pinion systems use an electric motor to pump the hydraulic fluid through the hoses. This statement is true.

The rack and pinion gearset is housed inside a metal tube, with each end of the rack protruding out and being attached to an axial rod. This is how it operates. When the steering wheel is twisted, the rack is moved by the pinion gear, which is mounted to the steering shaft. Based on the torque being given to the steering wheel by the driver, the steering wheel position, and the vehicle's speed, the EPS electronic control unit (ECU) determines the amount of aiding power required. With an applied force, the EPS motor rotates a steering gear, lowering the driver's necessary torque.

Explanation suggests that the MST will not be the same as T when it converts to T.

A minimum spanning tree (MST) for a weighted, connected and undirected graph is a spanning tree with weight less than or equal to the weight of every other spanning tree.

The new weight will be smaller than the original weight, or wnew < wnew, if we precisely lower the weight of one edge (let's say e).

There may now be two cases. - The modified edge e is a part of T and is a member of the MST. Since e is already a component of T, reducing its weight will also reduce the MST's weight. Consequently, the modified MST T is the same as the present MST T. (but with reduced weight by c).

The modified edge e does not belong to the MST since it is not a component of T. This might alter the existing MST since another MST that includes the updated edge e might exist with a lower weight. The MST does not change, thus if we find a situation where this is not the case, our assumption would be erroneous and T would not be the MST. This may be demonstrated by contradiction.

We may use the cyclic property of MST, which states that in order to obtain an MST, we need to eliminate the edge with the biggest weight in the cycle. The red edge in this graph was not included in the MST, hence its weight was reduced. The MST and the red edge combine to create a graph with a cycle. Using the cyclic property, subtract the cycle C's strongest edge to obtain the adjusted MST. O(V) time (where |V| is the number of vertices) can be used to complete this.

This suggests that the MST will not be the same as T when it converts to T.

Therefore, T will not surely be the MST if we reduce the weight of exactly one of the edges in G by a constant c as described by point 2.

Explanation:

The moment of inertia of the pendulum about an axis perpendicular to the page and passing through G will be 1.5 kgm².

A pendulum is a weight suspended from a pivot so that it can swing freely. The motion of a pendulum is a type of simple harmonic motion, which means that the pendulum moves back and forth in a regular, periodic fashion. The moment of inertia of an object is a measure of the object's resistance to change in its rotational motion.

To determine the location of the center of mass of the pendulum, we need to find the mass of each part and the distance from the center of mass of each part to point G.

The mass of rod AB is 3 kg/m * 1 m = 3 kg

The mass of rod OC is also 3 kg/m * 1 m = 3 kg

The mass of the plate is 12 kg/m2 * 1  = 12 kg

The distance from the center of mass of rod AB to point G is 0.5 m (since the rod is 1 m long and point G is at the midpoint of the rod)

The distance from the center of mass of rod OC to point G is also 0.5 m

The distance from the center of mass of the plate to point G is 0.5 m (since the plate is 1 m wide and point G is at the midpoint of the plate)

Now we can use the formula for the location of the center of mass:

yG = (3 kg * 0.5 m + 3 kg * 0.5 m + 12 kg * 0.5 m) / (3 kg + 3 kg + 12 kg) = 0.5 m

To calculate the moment of inertia of the pendulum about an axis perpendicular to the page and passing through G, we can use the formula for the moment of inertia of a rod about its center of mass:

[tex]I = (1/12) * m * L^2[/tex]

For rod AB:

[tex]I = (1/12) * 3 kg * (1 m)^2 = 0.25 kg*m^2\\[/tex]

For rod OC:

[tex]I = (1/12) * 3 kg * (1 m)^2 = 0.25 kg*m^2[/tex]

For the plate:

I = (1/12) * 12 kg * (1 m)^2 = 1 kg*m²

The total moment of inertia of the pendulum is the sum of the moments of inertia of the individual parts:

I = 0.25 kgm^2 + 0.25 kgm^2 + 1 kgm^2 = 1.5 kgm²
