<span>A Neutral, stable atom has no charge as it has an equal number of Protons and Electrons. An Atom gains a charge by the loss or gain of electrons thus becoming an Ion. The loss of 1 or more electrons will give the atom a Positive charge (now having more Protons then Neutrons) and becomes a Positive Ion (or Cation). hope that helped</span>

A block of mass 2 kg slides down ramp 1 with a height of 3 m. It then slides for 1 m on a surface with a kinetic coefficient of

Lady bird [3.3K]

Answer:

PE = 58.8,J

Explanation:

The potential energy at the top of ramp1 can be found by the application of the formula PE = mgh

Where PE =potential energy

m = mass of block = 2kg

g = acceleration due to gravity = 9.80m/s²

h = height of the top of the ramp from its bottom where the block is initially positioned = 3m

PE = 2×9.8×3 = 58.8J

Suppose you wish to construct a motor that produces a maximum torque whose magnitude is 1.7 × 10-2 N·m. The coil of the motor ha

Len [333]

Answer:

86 turns

Explanation:

Parameters given:

Magnetic torque, τ = 1.7 * 10^(-2) Nm

Area of coil, A = 9 * 10^(-4) m²

Current in coil, I = 1.1 A

Magnetic field, B = 0.2 T

The magnetic toque is given mathematically as:

τ = N * I * A * B

Where N = number of turns

To find the number of turns, we make N subject of formula:

N = τ/(I * A * B)

Therefore:

N = (1.7 * 10^(-2)) / (1.1 * 9 * 10^(-4) * 0.2)

N = 85.85 = 86 turns (whole number)

The number of turns must be 86.

The main illustration in the video shows the life track of a one-solar mass star. Each point along this track represents _______

REY [17]

Each point along the track of one solar mass star represents the star's surface temperature and luminosity at one time.

<h3>What is the one-solar mass star?</h3>

A star having a mass equal to the mass of the Sun is called a one-solar mass star.

Its life track shows the luminous intensity as well as the surface temperature.
