what does acceleRation measure

Answer:

Carbon 14 has 2 more neutrons than Carbon 12

same number of protons and electrons if they are both neutral atoms (that is the +  or - aspect)

Explanation:

Answer:

The difference is the number of neutrons they have.

Explanation:

The atomic number is the number of protons. The number of protons is what differentiates elements. The isotope number is the total weight of the atom, that is the protons plus the neutrons. Therefore the number of neutrons is equal to the atomic mass minus the atomic number. Electrons are generally equal to the number of protons, to balance the charge of the atom.

In short: the difference between the two isotopes is that one has more neutrons.

For our delicate measurement equipment to continue to operate accurately, gaussmeter calibration is necessary. In order to achieve this, we compare the instrument to one with a standard or greater accuracy. Then, if there is a deviation from the actual reading, we find it and fix it.

By delivering a reverse field to the magnet that is strong enough to bring the output (of flux) down to a reasonable level, magnetic calibration is accomplished.

Using a Tesla or Gauss metre, one may determine the intensity of a magnet's magnetic field. Many people who utilise magnets today possess their own Gauss metres and decide what magnetic field strengths are acceptable. The magnet analyzer will measure the magnetic field strength for multi-polar magnets.

The Hall Effect in semiconductors is the basis for how a digital Gauss metre functions. A voltage is created at a right angle to the current route when a semiconductor with current flowing in one direction is introduced perpendicular to a magnetic field.

The magnitude of the acceleration of the body is approximately 1.802 m/s^2 when forces of magnitude 5 Newton and 4 Newton act on a body of mass 4.0 kg at a right angle to each other.

To determine the magnitude of the acceleration of a body when two forces act on it at a right angle, we can use the Pythagorean theorem and Newton's second law of motion.Newton's second law states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma). In this case, the net force is the vector sum of the two forces acting on the body.Using the Pythagorean theorem, we can find the magnitude of the net force. Let's call the force with magnitude 5 Newton as F1 and the force with magnitude 4 Newton as F2. The net force (Fnet) can be calculated as the square root of the sum of the squares of the individual forces: Fnet = sqrt(F1^2 + F2^2).Now we can substitute the net force into Newton's second law to find the acceleration (a). Rearranging the formula, we have a = Fnet / m.Plugging in the values, Fnet = sqrt(5^2 + 4^2) = sqrt(25 + 16) = sqrt(41) Newtons. The mass (m) is given as 4.0 kg.

Finally, the magnitude of the acceleration of the body is calculated as a = Fnet / m = sqrt(41) / 4.0 ≈ 1.802 m/s^2.

Answer:1.36078

Explanation:

(a) When switch SA is closed, the current I1, I, and I2 just after the switch is closed can be determined by applying Kirchoff's Voltage Law (KVL). The KVL states that the sum of the voltage drops around a closed loop is equal to zero. Using this, the three currents can be determined as I1 = E/(R1 + R2), I2 = E/R2, and I = E/(R1 + 2R2).

(b) After a long time, the voltages and charges on each capacitor can be determined by applying the formula Q = CV, where Q is the charge, C is the capacitance, and V is the voltage across the capacitor.

(c) The ratio of the change in charge on a capacitor to the initial current through the capacitor gives the charging time (effective RC constant). The charging time for each capacitor can be determined by dividing the change in charge on the capacitor (Q) by the initial current (I).

(d) When switch Sg is closed, the voltages and charges on each capacitor after a long time can be determined by applying the same formulas as above.

I think its uniform I dont really know

The acceleration of a train  is -1.59m/sec²

We have initial speed and final speed of the the train, and we also have its distance.

We are assuming acceleration is constant, means that we can apply newton equation of motion.

Since, we have value of v, u and S and we need to find a, so we apply third equation of motion which is

v² - u² =2aS,

where v is final velocity, u is initial velocity, a is acceleration and S is the displacement/distance.

So, on putting this we get

=>7² - 19² =2×a×98

=>2×a×98= - 312

=>a=-1.59m/sec².

Here, negative sign shows that brakes are applied and speed of train is decreasing.

Hence, if the speed of a train is reduced uniformly from 19 m/s to 7 m/s while traveling a distance of 98 m, the acceleration is -1.59m/sec².

Top-Down: Gas and dark matter collided, causing the gas to star-form. merging of spiral galaxies whose gas has already turned into stars (bottom-up) is the way how the elliptical galaxy formation was happened.

spiral galaxies evolved from bottom-up, and elliptical galaxies from a mix of top-down and bottom-up. There is extremely little raw material for the creation of new stars in elliptical galaxies, in contrast to spiral galaxies, which contain abundant stores of the dust and gas that support star formation. When two spiral galaxies collide, they change from their recognized form into the less organized elliptical galaxies. These old galaxies are considered to be powered by a supermassive black hole.

The flea's initial velocity as it jumps is -2.45 m/s, calculated by using kinematic equations considering maximum height, acceleration due to gravity, and time.

To track down the underlying speed (v0) of the bug as it leaves the ground, we can utilize the accompanying kinematic condition:

d = vi * t + 0.5 * a * t^2

Where,

d = 0.500 m (the greatest level the insect comes to)

a = - 9.80 m/s^2 (speed increase because of gravity)

t = the time it takes for the insect to arrive at the greatest level

Since the bug hops straight up and arrives at a greatest level, its last speed by then will be 0 m/s. We can likewise utilize the accompanying condition to track down t:

vf = vi + at

Where,

vf = 0 m/s (last speed at the greatest level)

a = - 9.80 m/s^2 (speed increase because of gravity)

Subbing t from this situation into the primary condition, we can settle for the underlying speed vi:

0.500 = vi * t + 0.5 * (- 9.80) * t^2

vi * t = - 4.9 * t^2

vi = - 4.9 * t

Presently, subbing t and vi into the subsequent condition, we can settle for t:

0 = vi + (- 9.80) * t

0 = - 4.9 * t + (- 9.80) * t

9.80 * t = 4.9 * t

t = 4.9/9.80 = 0.5 s

At last, subbing t into vi = - 4.9 * t, we can track down the underlying speed:

vi = - 4.9 * 0.5 = - 2.45 m/s

Hence, the underlying speed of the insect as it leaves the ground is - 2.45 m/s.

a) Current through first  0.3 A, in second 0.15 A and in third 0.1 A. b) The total current through the circuit is the sum of the currents through each resistor. In this case, 0.3 A + 0.15 A + 0.1 A = 0.55 A.

a) A diagram of the resistors in a series circuit with a 3.0 V battery would look like this:

  -----|<|------|<|------|<|-----

        10Ω      20Ω      30Ω

        |        |        |

       (+)      (+)      (+)

        |        |        |

  ---------------------------

              (-)

In a series circuit, the resistors are connected end-to-end, so the current through each resistor is the same. Using Ohm's Law, we can find the current:

V = IR

I = V/R

For the first resistor, I = 3.0 V / 10 Ω = 0.3 A.

For the second resistor, I = 3.0 V / 20 Ω = 0.15 A.

For the third resistor, I = 3.0 V / 30 Ω = 0.1 A.

The potential difference across each resistor can be found by multiplying the current by the resistance:

V = IR

For the first resistor, V = 0.3 A * 10 Ω = 3.0 V.

For the second resistor, V = 0.15 A * 20 Ω = 3.0 V.

For the third resistor, V = 0.1 A * 30 Ω = 3.0 V.

So in a series circuit, the voltage is divided among the resistors, and the total voltage drop across all the resistors is equal to the battery voltage.

b)A diagram of the resistors in a parallel circuit with a 3.0 V battery would look like this:

        |--------|

  -----|<|       |--------|

        10Ω              |

        |--------|      |

                 |      |

  -----|<|       |--------|

        20Ω              |

        |--------|      |

                 |      |

  -----|<|       |--------|

        30Ω             (+)

        |--------|      |

                        |

  ----------------------

              (-)

In a parallel circuit, the resistors are connected across the battery, so the potential difference across each resistor is the same. The current through each resistor can be found using Ohm's Law:

V = IR

I = V/R

For the first resistor, I = 3.0 V / 10 Ω = 0.3 A.

For the second resistor, I = 3.0 V / 20 Ω = 0.15 A.

For the third resistor, I = 3.0 V / 30 Ω = 0.1 A.

So in a parallel circuit, the voltage is the same across all the resistors, but the current is divided among them. The total current through the circuit is the sum of the currents through each resistor. In this case, 0.3 A + 0.15 A + 0.1 A = 0.55 A.
