(a) Capacitance is =  1.10 x 10^-9 C (b) Magnitude is 2.75 x 10^-7 (c) Energy stored is 3.13 x 10^-6 J (d) New Capacitance is 2.95 x 10^-8 C (e) Charge on each plate is 7.38 x 10^-7 C (f) Energy is  3.70 x 10^-6 J (g) Max. voltage is 8.17 KV.

(a) The capacitance C of a parallel plate capacitor is given by the formula:

C = ε0 x A / d

where ε0 is the vacuum permittivity (8.854 x 10^-12 F/m), A is the area of the plates (0.80 m^2), and d is the separation between the plates (0.040 mm = 0.040 x 10^-3 m).

C = 8.854 x 10^-12 F/m x 0.80 m^2 / (0.040 x 10^-3 m) = 1.10 x 10^-9 F

So, the capacitance of the capacitor is 1.10 x 10^-9 F.

(b) The charge on each plate Q can be found using the formula:

Q = C x V

where V is the voltage applied to the capacitor (25 V).

Q = 1.10 x 10^-9 F x 25 V

= 2.75 x 10^-7 C

So, the magnitude of the charge on each plate is 2.75 x 10^-7 C.

(c) The energy stored in the capacitor can be calculated using the formula:

Energy = (1/2) x C x V^2

Energy = (1/2) x 1.10 x 10^-9 F x 25 V^2

= 3.13 x 10^-6 J

So, the energy stored in the capacitor is 3.13 x 10^-6 J.

(d) The new value of capacitance can be calculated using the formula:

C = εr x ε0 x A / d

where εr is the relative permittivity (310).

C = 310 x 8.854 x 10^-12 F/m x 0.80 m^2 / (0.040 x 10^-3 m)

= 2.95 x 10^-8 F

So, the new value of capacitance is 2.95 x 10^-8 F.

(e) For a voltage of 25 V, the charge on each plate can be found using the formula:

Q = C x V

Q = 2.95 x 10^-8 F x 25 V = 7.38 x 10^-7 C

So, the charge on each plate is 7.38 x 10^-7 C.

(f) The energy stored in the capacitor can be calculated using the formula:

Energy = (1/2) x C x V^2

Energy = (1/2) x 2.95 x 10^-8 F x 25 V^2

= 3.70 x 10^-6 J

So, the energy stored in the capacitor is 3.70 x 10^-6 J.

(g) The maximum voltage that can be placed across the capacitor can be calculated using the formula:

Vmax = d x ε x E / ε0

where ε is the dielectric constant (310), E is the electric field strength (8.0 kV/mm), and d is the separation between the plates (0.040 mm = 0.040 x 10^-3 m).

Vmax = 0.040 x 10^-3 m x 310 x 8.0 kV/mm / (8.854 x 10^-12 F/m)

= 8.17 kV

So, the maximum voltage that can be placed across the capacitor is 8.17 kV.

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 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.

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.

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.

Since the ideal voltmeter reads 3.2V, rearranging and solving for R gives R = V/I = 3.2V/4.0A = 0.8Ω. Ohm's law states that the voltage (V) across a resistor is equal to the current (I) multiplied by the resistance (R): V = I x R.

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.

The electric field is 490 N/C.

The formula of the electric field of a charge sheet in terms of surface charge density σ and the formula of surface charge density are shown below:

          E = σ/2ε  and σ = q/A

Using these two, we get:

          E = q/2Aε

Where,

q = charge = 26mC = 26* 10^-3 C

A = Area of sheet = 1.5*2 = 3 km^2 = 3 * 10^3 m^2

ε = permeability = 8.85 * 10^-12

Putting these values in above equation we get: E = 490 N/C
