Which is an example of current electricity

Answer: No

Explanation:

There are a few explanations as to why. I'm not sure as to what level of an explanation you are looking for. A person's body is made of atoms, which have constant motion due to multiple processes. An atom can never ever be frozen to absolute zero motion, we can only approach that value. Therefore, we will always have kinetic energy. Another explanation is Einstein's famous formula E = mc^2. This is the rest mass energy, which all things with mass obey. There is an energy-mass equivalence.

[tex]\sf\huge\underline\blue{Resistor:-}[/tex]

[tex]\rightarrow[/tex]A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element.

[tex]\rightarrow[/tex]Resistors reduce the current flow and lower voltage levels within circuits.

[tex]\sf\large\underline\purple{Resistors \:in\: Series:-}[/tex]

[tex]\rightarrow[/tex]A circuit is said to be connected in series when the same amount of current flows through the resistors. In such circuits, the voltage across each resistor is different.

[tex]\rightarrow[/tex]In a series connection, if any resistor is broken or a fault occurs, then the entire circuit is turned off. The construction of a series circuit is simpler compared to a parallel circuit.

[tex]\rightarrow[/tex]For the above circuit(attached image-1), the total resistance is given as:

[tex]\sf{R_{total}\: = \:R1 + R2 + ….. + Rn}[/tex]

The total resistance of the system is just the total of individual resistances.

[tex]\sf\large\underline\purple{Resistors \:in\: Parallel:-}[/tex]

[tex]\rightarrow[/tex]A circuit is said to be connected in parallel when the voltage is the same across the resistors. In such circuits, the current is branched out and recombines when branches meet at a common point.

[tex]\rightarrow[/tex]A resistor or any other component can be connected or disconnected easily without affecting other elements in a parallel circuit.

[tex]\rightarrow[/tex]The figure(attached image -2) above shows ‘n’ number of resistors connected in parallel. The following relation gives the total resistance here

[tex]\sf{\frac{1}{R_{total}}\: = \:\frac{1}{R1} + \frac{1}{R2} + ….. + \frac{1}{Rn}}[/tex]

[tex]\rightarrow[/tex]The sum of reciprocals of resistance of an individual resistor is the total reciprocal resistance of the system.

Answer:

In a series circuit, the output current of the first resistor flows into the input of the second resistor; therefore, the current is the same in each resistor. In a parallel circuit, all of the resistor leads on one side of the resistors are connected together and all the leads on the other side are connected together.

Answer:

About 59.83 kg

Explanation:

The formula for kinetic energy is [tex]KE = \frac{1}{2}mV^2[/tex], where KE = Kinetic Energy in Joules (J), m = mass in kilograms (kg), and V = Velocity in meters per second (m/s).

In this problem, we are given the Kinetic Energy amount as 193 Joules and the Velocity as 2.54 m/s. Let's plug it into our equation

Now, let's solve this equation.

Step 1: Simplify both sides of the equation.

Step 2: Divide both sides by 3.2258.

Force(F) = 150N

Mass(m) = 90kg

Acceleration(a) = ?

F= m×a

[tex]150 = 90 \times \text{a} \\ \\ \text{a} = \frac{150}{90} \\ \fbox{cancelling by 3} \\ \\ \text{ a} = \cancel \frac{150}{90} \\ \\ \text{ a} = \frac{5}{3} = 1.67 \text{m/s} {}^{2} [/tex]

[tex] \therefore \text{Option A= 1.67 m/s² is the correct answer}[/tex]

Answer:

A. 1.67 m/s2

Explanation:

F = m*a, so a = F/m = 150/90 ≈ 1.67 [tex]m/s^2[/tex]

The energy of the ball at its highest position is potential energy.

The law of conservation of energy states that, energy can neither be created nor destroyed. Despite this, it is capable of changing its form. The sum of the energies in an isolated system is constant regardless of the types of energy present.

Here,

According to law of conservation of energy, at each position of the ball, it will have some amount of energy.

At point A

The ball is at its highest position, that means maximum height. So, the energy of the ball at that position is potential energy and it doesn't have any kinetic energy.

At points B and C

At these positions the ball is moving downwards. That means the potential energy is being converted into kinetic energy of the ball. So, it has both PE and KE.

At point D

The ball is at the lowest position, on the ground. So, the potential energy is zero. Therefore, it has the kinetic energy.

At points E and F

At these positions, the ball is moving upwards. So, it has both PE and KE.

Hence,

The energy of the ball at its highest position is potential energy.

The hot summer cottage she left in September will still be hot when she returns in June as long as no one enters it (Isolated).

The second law of thermodynamics states that, hot things always cool unless you do something to stop them. Or the total entropy of an isolated system can never decrease.

In other words, not all heat energy can be converted into work in a cyclic process.

Therefore, we can conclude that when the woman returns, the hot summer cottage she left in September will still be hot when she returns in June as long as no one enters it (Isolated).

  cue ball final: 0.85 m/s at N65°W

  8-ball final: 1.27 m/s at N12°E

Explanation:

In a perfectly elastic collision, both momentum and energy are conserved. The momentum is the sum of products of mass and velocity. The energy is half the product of mass and the square of velocity. The difference of "particle" velocities changes sign as a consequence of the collision.

If we let the masses be m1 and m2, the corresponding initial velocities be v1 and v2, and the final velocities be u1 and u2, we have ...

  m1·u1 +m2·u2 = m1·v1 +m2·v2 . . . . . . . conservation of momentum

  u1 -u2 = v2 -v1 . . . . . . . . . . . . . . . relative velocity sign changes

This pair of linear equations can be solved for u1 and u2 in any of the usual ways to give ...

  u1 = v1(m1 -m2)/(m1 +m2) + v2(2·m2)/(m1 +m2)

  u2 = v2(m2 -m1)/(m1 +m2) +v1(2·m1)/(m1 +m2)

Answer:

W = M g = 150 kg * 9.81 m/s^2 = 1470 N

You were only given 3 significant figures in the question.

The weight of the box is 1471.5 N.

In science and engineering, an object's weight is defined as the force of gravity acting on the thing. Weight is sometimes described as a vector quantity in common textbooks, denoting the gravitational force acting on the item.

Given parameters:

Mass of the box, m = 150 kg.

Acceleration due to gravity, g = 9.8 m/s².

Hence, weight of the box is, W = mg = 150 kg × 9.81 m/s² =1471.5 N.

SO, weight of the  box with a mass of 150 kg on Earth is 1471.5 N.
