To find the mass in kilograms, you need to know the object's weight in newtons and the acceleration due to gravity. The formula for finding mass is mass = weight / acceleration due to gravity. So if you have an object with a weight of 100 N and the acceleration due to gravity is 9.8 m/s^2, the mass would be 10.204 kg.

The mass of the block is 0.025 kg or 25 g, when the spring has k = 28 N/m, and compresses 0.11 m before bringing the block to rest.

Okay, here are the steps to solve this problem:

1) The seesaw is balanced when the sum of moments is 0.

2) The moment created by a force depends on the force and the perpendicular distance from the pivot point.

3) The 20 kg child sits 1 meter from the pivot. So its moment is 20 * 1 = 20 kg*m.

4) We want to find the distance for the 40 kg child to create a moment that balances the 20 kg child's moment.

5) So the moment of the 40 kg child must be 20 kg*m.

6) The moment depends on force and distance. We know the force is 40 kg.

7) So we set: 40 kg * distance = 20 kg*m

8) And solve for the distance: distance = 20 / 40 = 0.5 meters

Therefore, for the seesaw to balance with a 20 kg child 1 meter from the pivot and a 40 kg child on the other side, the 40 kg child should sit 0.5 meters from the pivot point.

The resistance to flow over the membrane is represented by two resistors with resistances R1 = 10 k and R2 = 90 k. SW1 is a switch that represents variability.

A. When the switch SW1 is closed, the current flowing around the loop can be found using Kirchhoff's loop rule. Thus, the total voltage drop around the loop is V1 - IR1 + V2 - IR2 = (V1 + V2) - I(R1 + R2). Since the loop is a closed circuit, the current I must be the same everywhere, so we have I = (V1 + V2)/(R1 + R2) = (100 mV + 50 mV)/(10 kΩ + 90 kΩ) = 1.0 μA (microampere).

B. When the switch SW1 is open, no current flows through the resistor R1, so the voltage drop across it is zero (0 V). When the switch is closed, the voltage drop across R1 can be found using Ohm's law: V1 - IR1 = (100 mV) - (1.0 μA)(10 kΩ) = 90 mV.

C. When the switch SW1 is open, no current flows through the resistor R2, so the voltage drop across it is zero (0 V). When the switch is closed, the voltage drop across R2 can be found using Ohm's law: V2 - IR2 = (50 mV) - (1.0 μA)(90 kΩ) = -35 mV.

D. Since we have defined point b as having a voltage of 0 V, the voltage at point d is simply the voltage drop across R2, which we found to be -35 mV. Thus, the voltage difference across the membrane is 0 V - (-35 mV) = 35 mV.

E. However, the current flowing around the loop would be different, since the resistance of the path between points a and d would be different. Specifically, when R1 and R2 are swapped, the current flowing around the loop when the switch is closed would be (V1 - V2)/(R2 + R1) = (100 mV - 50 mV)/(90 kΩ + 10 kΩ) = 0.5 μA, which is half the value we calculated earlier.

The angular velocity is 3.75 m/s and the centripetal force is 225 N respectively.

The angular velocity of an object with respect to some extent is a degree of the way rapid that item actions through the point's view, within the feel of the way speedy the angular function of the item modifications. An instance of angular pace is a ceiling fan. One blade will whole a complete round in a certain amount of time T, so its angular speed with respect to the middle of the ceiling fan is twoπ/T.

Calculation:-

A. angular velocity ω = v/r

                                     = 30 /8

                                      = 3.75 m/s

B. Centripetal force = mv²/r

                             = 2×30²/8

                              = 225 N

There are 3 formulations we will use to find the angular velocity. the primary comes instantly from the definition.

Answer: To find the total resistance of the wires, we need to use a formula that takes into account the length and cross-sectional area of the wires and the resistivity of the material they are made of. By plugging in the appropriate values for the length, cross-sectional area, and resistivity of the wires in the formula, we can find the individual resistances of the wires. Then, by using another formula for the total resistance of a parallel combination, we can find the effective resistance of the wires in parallel.

Explanation:R = ρ * (L / A)

where R is the resistance of the wire, ρ is the material's resistivity (resistance per unit length), L is the length of the wire, and A is the cross-sectional area of the wire.
according to the given data
AP= 40 cm
px=60cm

Next, we need to calculate the wire PX's length and cross-sectional area. The length is given as 60 cm, and we can assume the same diameter of 1 mm, giving a cross-sectional area of 0.785 mm^2.

Now we can calculate the resistance of each wire using the formula above:

R_AX = ρ * (80 cm / 0.785 mm^2) = 101.91 * ρ

R_PX = ρ * (60 cm / 0.785 mm^2) = 76.43 * ρ

The total resistance of the parallel combination is given by the formula:

1/R_total = 1/R_AX + 1/R_PX

Substituting the values of R_AX and R_PX, we get:

1/R_total = 1/(101.91 * ρ) + 1/(76.43 * ρ)

1/R_total = (1.55 / ρ)

R_total = ρ / 1.55

therefore, the effective resistance of the parallel combination is (ρ / 1.55) ohms

Based on the information, it should be noted that the resistance R is 0.5 Ω.

When S1 and S2 are open, i leads e by 30°. In this case, the circuit consists of only the inductor (L) and the capacitor (C) in series. Therefore, the impedance of the circuit can be written as:

Z = jωL - 1/(jωC)

Since i leads e by 30°, we can express the phasor relationship as:

I = k * e^(j(ωt + θ))

Z = jωL - 1/(jωC) = j(120π)L - 1/(j(120π)C)

Re(Z) = 0

By equating the real parts, we get:

0 = 0 - 1/(120πC)

Let's assume that there is a resistance (R) in series with the inductor and capacitor. The impedance equation becomes:

Z = R + jωL - 1/(jωC)

Z = R + jωL

Im(Z) = ωL > 0

Substituting the angular frequency and rearranging the inequality, we have:

120πL > 0

L > 0

This condition implies that the inductance L must be greater than zero.

When S1 and S2 are closed, i has an amplitude of 0.5 A. In this case, the impedance is:

Z = R + jωL - 1/(jωC)

Since the amplitude of i is given as 0.5 A, we can express the phasor relationship as:

I = 0.5 * e^(j(ωt + θ))

By substituting this phasor relationship into the impedance equation, we can determine the value of R. The real part of the impedance must be equal to R:

Re(Z) = R

Since the amplitude of i is 0.5 A, the real part of the impedance must be equal to 0.5 A: 0.5 = R

Therefore, the resistance R is 0.5 Ω.

-400=40a

a = -10 m/s^2

ans affect acceleration is 10 m/s^2

The magnitude of the electric field between the plates is 5.87 × 10^5 N/C.

The electron gains kinetic energy as it is accelerated across the gap of the capacitor. This energy is equal to the work done on the electron by the electric field between the plates of the capacitor. We can use this relationship to determine the magnitude of the electric field.

The kinetic energy gained by the electron can be expressed as:

K = (1/2)mv^2

where K is the kinetic energy, m is the mass of the electron, and v is its velocity. The work done on the electron by the electric field is given by:

W = qEd

where W is the work done, q is the charge of the electron, E is the electric field, and d is the distance between the plates.

Since the electron is negatively charged, it will be accelerated from the negative plate (-Q) to the positive plate (+Q) of the capacitor. The charge on an electron is -1.602 × 10^-19 C. Therefore, the work done on the electron is:

W = qEd = (-1.602 × 10^-19 C)(E)(0.94 m)

The kinetic energy gained by the electron is equal to the work done on it by the electric field, so:

K = W = (1/2)mv^2

Substituting the known values and solving for the electric field gives:

E = (2qK) / (md^2) = (2(-1.602 × 10^-19 C)(0.5m_e(27 m/s)^2)) / ((9.11 × 10^-31 kg)(0.94 m)^2)

where m_e is the mass of the electron.

E = 5.87 × 10^5 N/C

Therefore, the magnitude of the electric field between the plates is approximately 5.87 × 10^5 N/C.
