what is the minimum diameter for an objective lens that will just barely resolve jupiter and the sun? the radius of jupiter's orbit is 780 million kmkm. assume λλlambda =600nm

An increase in the distance between the objects causes a greater change in the gravitational force than the same increase in mass. It depends on the object's mass and acceleration due to gravity.

Mass is an intrinsic unchanging property. Weight is a force and it depends on gravitational force. This force is directly proportional to mass the more mass the object has the stronger the force of gravity will be. Because of this, it turns out that gravity does not matter when we compare the distance traveled by objects with different masses. The important part of the force is air resistance also called drag.

The slope of the graph is the relationship between weight and mass. The slope tells how many newtons of weight pull down on each kilogram of mass. Mass is the measure of the amount of matter in an object. This is an immutable property inherent in the body. Mass cannot be destroyed or created. Weight is the production of mass and acceleration due to gravity.

The energy and power of the complex signal x[n] = re^(jπ/4)n can be determined by analyzing its mathematical properties.

To find the energy and power of the complex signal x[n] = re^(jπ/4)n, we need to evaluate the given expression. Let's break it down step by step. Here, "re" represents a real constant and "j" denotes the imaginary unit.

The signal x[n] = re^(jπ/4)n can be written as x[n] = r * 3^(n) * e^(jπn/4). The term r * 3^(n) is a geometric progression that grows or decays depending on the value of r. The exponential term e^(jπn/4) represents a rotating phasor with a phase angle of π/4.

To calculate the energy, we need to find the sum of the squared magnitudes of each sample of the signal over all time indices. Since the magnitude of e^(jπn/4) is constant (equal to 1), the energy of x[n] is proportional to the sum of the squared magnitudes of r * 3^(n). Depending on the value of r, the energy may vary.

The power of a discrete-time signal is the average energy per unit time. In this case, since the signal is defined in discrete-time, the power is determined by dividing the energy by the total number of samples in the signal.

In conclusion, to determine the energy and power of the complex signal x[n] = re^(jπ/4)n, we need to analyze the geometric progression component and consider the constant term r. The energy depends on the sum of squared magnitudes of r * 3^(n), while the power is calculated by dividing the energy by the total number of samples in the signal.

The pucks are covered with velocity so they stick together after the collision.The final velocity of the two pucks is 0.33 m/s.



Applying conservation of linear momentum we get,

mv_1 + 2m.v_2 = (m+2m)v

= v = mv_1 +2mv_2 / m + 2m

= v =v_1 + 2v_2 / 3

Assuming +ve in the right side and -ve in the left side weget

v1 =3m/s v2=-1m/s

v =3+2x(4) / 3 =3-2 / 3 = 1 / 3

= v = 0.33 m/s        As it is +ve so it moves to the right

The time required for a signal to travel 0.200 m through an optical fiber with an index of refraction of n = 1.55 is approximately 1.03 nanoseconds.

To calculate the time required for a signal to travel through the optical fiber, we need to use the formula:

t = d / v

where t is the time, d is the distance traveled by the signal, and v is the velocity of the signal in the medium (which is determined by the index of refraction).

In this case, we are given that the index of refraction is n = 1.55. The velocity of light in a medium with this index of refraction is:
v = c / n
where c is the speed of light in a vacuum (which is approximately 3 x 10^8 m/s).

Plugging in the numbers, we get:
v = (3 x 10^8 m/s) / 1.55 = 1.94 x 10^8 m/s
Now we can calculate the time required for the signal to travel 0.200 m:

t = d / v = (0.200 m) / (1.94 x 10^8 m/s) = 1.03 x 10^-9 s = 1.03 ns

Therefore, the time required for a signal to travel 0.200 m through an optical fiber with an index of refraction of n = 1.55 is approximately 1.03 nanoseconds.

The EGC for a flexible metal conduit connection to a motor supplied with a 20A circuit is a 12 AWG copper conductor.

The EGC (Equipment Grounding Conductor) for a flexible metal conduit connection to a motor supplied with a 20A circuit is determined by the sizing requirements of the NEC (National Electrical Code). The NEC specifies the minimum size of the EGC based on the size of the circuit conductors and the type of conduit used.

To determine the minimum size of the EGC, we need to consult the NEC Table 250.122, which provides the minimum size of the EGC based on the size of the circuit conductors.

Since the circuit is supplied with a 20A current, we will assume that the circuit conductors are sized accordingly. According to the NEC Table 310.15(B)(16), a 20A circuit typically uses a 12 AWG copper conductor.

Next, we need to determine the type and size of the flexible metal conduit used for the connection. Different types of conduits have different requirements for the EGC sizing. For instance, for a flexible metal conduit, the NEC Table 250.122 specifies that a 12 AWG copper conductor should be used if the conduit is 3/4" or smaller.

Therefore, based on the information provided, the EGC for a flexible metal conduit connection to a motor supplied with a 20A circuit is a 12 AWG copper conductor.

T1, T2, T3, T4, and their respective tensions are all equal to 735 N.

Given,

Mass of the object (m) = 300kg

Acceleration due to gravity (g) = 9.8 m/s²

Since all the ropes are the same length and have an exact symmetry into the four quarters, symmetry ensures that all the ropes are under the same tension. Thus, the combined tension of the four ropes balances the weight of the block. So, the tension in a single rope is equal to four times the weight.

Thus, 4 × tension = weight = mg  

4 × Tension = 300 × 9.8 = 2940 N

Explanation:

K.E.=(1/2)(200)(18^2)

The frequency of the waves when a 0.5 kg mass is hanging on the end of a piece of fishing line is determined by the tension and length of the line.

The frequency of the waves on a piece of fishing line can be determined using the formula f = (1/2L)√(T/μ), where f is the frequency in hertz, L is the length of the line, T is the tension in newtons, and μ is the linear mass density of the line in kg/m.

In this case, the mass of the hanging object is 0.5 kg, so the tension of the line will be affected by the weight of the object as well as any other forces acting on it.

Assuming the line is under tension and the mass is held steady, the length of the line will determine the frequency of the waves. A shorter line will have a higher frequency, while a longer line will have a lower frequency.

Additionally, the tension of the line will affect the frequency - a higher tension will result in a higher frequency, while a lower tension will result in a lower frequency.

Therefore, the frequency of the waves when a 0.5 kg mass is hanging on the end of a piece of fishing line will depend on the tension and length of the line.

The airline will need to have at least 167 passengers on each flight to break even.

To calculate the number of passengers needed to break even, we need to consider the total costs and the revenue generated per flight.

The total cost per flight consists of the fixed costs (£25,000) and the variable costs (£75 per passenger). The revenue per flight is determined by the ticket price (£225) multiplied by the number of passengers.

Let's denote the number of passengers as 'P'. The total cost per flight is given by:

Total Cost = Fixed Costs + (Variable Cost per Passenger * Number of Passengers)

Total Cost = £25,000 + (£75 * P)

The revenue per flight is given by:

Revenue = Ticket Price * Number of Passengers

Revenue = £225 * P

To break even, the total cost should equal the revenue:

£25,000 + (£75 * P) = £225 * P

Now, we can solve this equation for P to find the number of passengers needed to break even:

£25,000 + (£75 * P) = £225 * P

£25,000 = £225 * P - £75 * P

£25,000 = £150 * P

P = £25,000 / £150

P ≈ 166.67

Since the number of passengers must be a whole number, we round up to the nearest whole number:

P = 167

The airline will need at least 167 passengers on each flight to break even. However, since the maximum capacity of the aircraft is 200 passengers, the airline will need to fill the aircraft to its maximum capacity to break even on each flight.

The voltage across the 170 Ω resistor in the series circuit is approximately 4.25 V.

To find the voltage across a resistor in a series circuit, we need to use Ohm's law, which states that V = IR, where V is voltage, I is current, and R is resistance. In a series circuit, the current is the same through all resistors, so we can use the total circuit resistance and the battery voltage to calculate the current, and then use that current and the resistance of the desired resistor to find the voltage drop across that resistor.

To find the total resistance of the circuit, we add the resistances of each resistor:

R_total = 170 Ω + 240 Ω + 65 Ω

R_total = 475 Ω

To find the current in the circuit, we use Ohm's law again:

I = V / R_total

I = 12 V / 475 Ω

I ≈ 0.025 A

Now we can find the voltage drop across the 170 Ω resistor:

V_170 = IR_170

V_170 = 0.025 A x 170 Ω

V_170 = 4.25 V

Therefore, the voltage across the 170 Ω resistor in the series circuit is approximately 4.25 V.
