Answer:

Generally, these models have shed more light on the field of atom by describing the composition of atoms and how the atom functions . The competition of these models have been able to modify atomic model to it actual description, modification and functionality.      

Explanation:

There have been different models of atoms overtime . The competition between the various models of atom have been able to shed more light on atom and create more theory on the subject of atoms. The well known models of atom are Dalton's atomic model, Thomson's model of the atom , Ernest Rutherford model of atom, Niels Bohr's model and Schrödinger's model of atoms.

Dalton stated that atoms are indivisible and he was able to realize atom of a particular element different from others . That means atoms of the same element are identical. J.J Thompson was able to recognized electrons in atoms  he drew a plum pudding model  of an atom. It shows electron revolves around a positive charge through out a spherical cloud. Rutherford was able to detect positive charge of an atom found in the nucleus of an atom. Bohr's model modified Rutherford's model . He was able to recognized that the electron move or orbit around the nucleus. Schrödinger's  believes electrons moves around the nucleus in cloud and has an uncertain position.

Generally, these models have shed more light on the field of atom by describing the composition of atoms and how the atom functions . The competition of these models have been able to modify atomic model to it actual description, modification and functionality.

A 49.5-turn circular coil of radius 5.10 cm can be oriented in any direction in a uniform magnetic field having a magnitude of 0
ipn [44]

Answer:

The magnitude of the maximum possible torque exerted on the coil is 5.73 x 10⁻³ Nm

Explanation:

Given;

number of turns of the circular coil, N = 49.5 turns

radius of the coil, r = 5.10 cm = 0.051 m

magnitude of the magnetic field, B = 0.535 T

current in the coil, I = 26.5 mA = 0.0265 A

The magnitude of the maximum possible torque exerted on the coil is calculated as;

τ = NIAB

where;

A is the area of the coil

A = πr² = π(0.051)² = 0.00817 m²

Substitute the given values and solve for the maximum torque

τ = (49.5) x (0.0265) x (0.00817) x (0.535)

τ = 0.00573 Nm

τ = 5.73 x 10⁻³ Nm

While skydiving, your parachute opens and you slow from 50.0 m/s to 8.0 m/s in 0.75 s . Determine the distance you fall while th
Anestetic [448]

Answer:

21.75 m

Explanation:

t = Time taken for the car to slow down = 0.75 s

u = Initial velocity = 50 m/s

v = Final velocity = 8 m/s

s = Displacement

a = Acceleration

Equation of motion

v=u+at\\\Rightarrow a=\frac{v-u}{t}\\\Rightarrow a=\frac{8-50}{0.75}\\\Rightarrow a=-56\ m/s^2

Acceleration is -56 m/s²

v^2-u^2=2as\\\Rightarrow s=\frac{v^2-u^2}{2a}\\\Rightarrow s=\frac{8^2-50^2}{2\times -56}\\\Rightarrow s=21.75\ m

The distance covered in the 0.75 seconds is 21.75 m

Answer:

72 m

Explanation:

Given:

v₀ = 0 m/s

v = 60 m/s

a = 25 m/s²

Find: Δx

v² = v₀² + 2aΔx

(60 m/s)² = (0 m/s)² + 2 (25 m/s²) Δx

Δx = 72 m
