what is the value of the electric field .3 m from a square piece of metal which is 1.5 km x 2 km and has a net charge of 26 mc?

The loss of an electrical signal over distance as it travels along a conductor due to resistance is referred to as voltage drop. Thus, the correct option is B.

Voltage drop is the decrease of the electric potential along the path of a current which is flowing in an electric circuit. Voltage drops in the internal resistance of the source of an electric circuit, across the conductors, across contacts, and across the connectors of an electric circuit are all  undesirable because some of the energy supplied to it is dissipated.

Voltage drop of the circuit with conductors can be determined by multiplying the current flowing through the electric circuit with the total resistance of the circuit conductors of the electric circuit:

VD = I x R

where, VD = Voltage Drop,

I = Electric current,

R = Resistance.

Therefore, the correct option is B.

The percentage of mass is electrons in carbon-12 is 50, 02%.

Every  element's atomic mass is expressed in terms of the atomic mass unit (AMU or amu). The AMU expresses both the atomic masses and the molecular masses and is commonly  referred to as the dalton (Da) or unified atomic mass unit (u). AMU is explained  as being one-twelfth the mass of a carbon-12 atom (12C). A carbon-12 atom's mass is precisely 1/12 of an atomic mass unit. The nucleus of an atom of carbon-12 contains six neutrons and six protons. It's written as a.m.u or u. (unified). Atomic masses are expressed using this unit of mass. The average of the neutron rest mass and the proton rest mass is 1 a.m.u. The carbon-12 atom contains 6 protons, neutrons, and electrons. The mass proportion of neutrons is therefore equal to: 6x1.0087/(6x1.0087+6x1.0073+6x5.4858x10^-4)=0.50021110822=50,021110822%.

To determine the maximum weight of the crate so that the tension developed in any cable does not exceed 600 lb, you need to calculate the tension in each cable and make sure it does not exceed 600 lb.

This can be done by calculating the force between the crate and each cable, and then dividing by the total number of cables. For example, if the force between the crate and a single cable is 1200 lb, then the maximum weight of the crate should be 600 lb.

Therefore, if you are using multiple cables, you may be able to increase the maximum weight of the crate by distributing the weight among the cables. Additionally, the distance between the load and the attachment points of the cables affects the tension in each cable as well.

The satellite's total energy in its stable orbit at an altitude of 4.0 × 10⁵ m above Earth's surface is approximately -1.052 × 10¹¹ Joules, predominantly gravitational potential energy.

To calculate the satellite's total energy in this orbit.

Given:

m₁ (mass of satellite) = 1500 kg

m₂ (mass of Earth) = 5.972 × 10²⁴ kg

r (distance from center of Earth to satellite) = 4.0 × 10⁵m + 6.371 × 10⁶ m

First, let's calculate the gravitational potential energy (U):

U = -G * (m₁ * m₂) / r

U = -6.674 × 10⁻¹¹ m³ kg⁻¹ s⁻² * (1500 kg * 5.972 × 10²⁴ kg) / (4.0 × 10⁵ m + 6.371 × 10⁶ m)

Calculating this expression:

U ≈ -1.123 × 10¹¹ J

Next, let's calculate the velocity of the satellite (v):

v = sqrt(G * m₂ / r)

v = sqrt(6.674 × 10⁻¹¹ m³ kg⁻¹s⁻² * 5.972 × 10²⁴ kg / (4.0 × 10⁵ m + 6.371 × 10⁶ m))

Calculating this expression:

v ≈ 3077 m/s

Now, let's calculate the kinetic energy (K):

K = (1/2) * m1 * v²

K = (1/2) * 1500 kg * (3077 m/s)²

Calculating this expression:

K ≈ 7.096 × 10⁹ J

Finally, let's calculate the total energy (E):

E = U + K

E = -1.123 × 10¹¹J + 7.096 × 10⁹ J

Calculating this expression:

E ≈ -1.052 × 10¹¹J

Therefore, The satellite's total energy in this orbit is approximately -1.052 × 10¹¹ Joules. The negative sign indicates that the energy is gravitational potential energy dominated, as expected in a stable orbit.

The acceleration will be the same if he pulls with the same force, regardless of the mass of the child or the wagon.

Acceleration is defined as the change in velocity per unit of time and is determined by the net force acting on an object. The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

According to Newton's second law of motion, the force required to achieve a certain acceleration is equal to the mass of the object multiplied by the acceleration. So, if the force applied is constant, the acceleration will be inversely proportional to the mass of the object.

In this scenario, the child's mass is three times that of the wagon, but if the same force is applied to both, the acceleration will still be the same. This is because the net force remains constant, and since the acceleration is inversely proportional to the mass, the acceleration of the combined system (child and wagon) will remain the same.

Remember that the insulating material that makes up ball C can become polarised in the presence of an externally charged item like ball A. Because the positive and negative charges in ball C are located at slightly different average distances from ball A, there will be a weak attraction between the two balls once they are polarised. The test charge would exhibit the same response (weakly attracting), but it would interact weakly repulsively with ball A if ball C contained a very little negative charge. A smaller negative charge is not a possibility, though. Ball C must have zero net charge because the test charge T is neither powerfully attracted to nor repelled by it.

complete question: What is the nature of the force between balls

A and C?

a. strongly attractive

b. strongly repulsive

c. weakly attractive

d. neither attractive nor repulsive

Answer:

The impulse exerted on the ball is 180 N and the collision time is 0.15 seconds.

Explanation:

a) The impulse exerted on an object can be calculated by multiplying the force applied by the time over which it is applied:

Impulse = Force * time

We can use the equation of motion to find the time of collision:

v = u + at

where v is the final velocity, u is the initial velocity (0 m/s in this case), a is the acceleration and t is the time of collision.

Combining these equations, we have:

Impulse = m * (v - u)

= m * a * t

= m * (v - 0) / t

= m * v / t

Plugging in the values, we have:

Impulse = 45 kg * 18 m/s / t

Dividing both sides of the equation by t, we have:

180 N = 45 kg * 18 m/s / t

Solving for t, we have:

t = (45 kg * 18 m/s) / 180 N

b) The collision time can be calculated by rearranging the above equation:

t = (45 kg * 18 m/s) / 180 N

t = 0.15 seconds

So the impulse exerted on the ball is 180 N and the collision time is 0.15 seconds.

a.There are two types of charge: positive and negative. This is based on the observation that when two objects are rubbed together, they can either become positively charged or negatively charged. Additionally, when objects with different charges are brought near each other, they experience a force that depends on their charges.

The direction of the force is attractive if the charges are opposite, and repulsive if the charges are the same. These observations have been repeatedly confirmed in many experiments and are widely accepted in the scientific community.

Charge is conserved, meaning the total charge in a closed system remains constant. When two objects are rubbed together, they can transfer electrons and become charged. Opposite charges are attracted to each other, while like charges are repelled.
