<span>The product that tells when tropical storm-force winds can be expected in your area is called a wind speed probability products. This probability product comes up with a forecast that gives the probable wind speeds (percentage-wise) that are likely to subside in the given area. This product works for winds that are tropical and greater than 39 mph.</span>
Answer:
wrong answer because m=100
The speed of the particle to pass through the Selector is 2875 m/s
<u>Explanation:</u>
Given -
Electric field,(We can represent as E) = 460 N/C
Magnetic field, (We can represent as B) = 0.16 T
Speed,(We can represent as v) = ?
We know that the formula for finding the velocity ,
Therefore, speed of the particle to pass through the Selector is 2875 m/s
Answer:
F = π/4 ρ d² v²
Explanation:
Force is mass times acceleration:
F = ma
Acceleration is change in velocity over change in time:
F = m Δv / Δt
Since there's no rebound, Δv = v.
F = m v / Δt
Mass is density times volume:
F = ρ V v / Δt
Volume per time is flow rate:
F = ρ Q v
Flow rate is velocity times cross sectional area:
F = ρ (v A) v
F = ρ A v²
Area of a circle is pi times radius squared, or pi/4 times diameter squared:
F = ρ (π/4 d²) v²
F = π/4 ρ d² v²
Answer:
15 protons and 18 electrons
General Formulas and Concepts:
<u>Chemistry</u>
- Reading a Periodic Table
- Element Number
- Neutral Atoms
- Ions
Explanation:
We are given the element P. P is 15 on the Periodic Table, meaning it has 15 protons and 15 electrons (all elements are in neutral form).
P³⁻ ion means the element now has a negative charge of 3. We know protons have a positive charge and electrons have a negative charge. 3- means we will have more electrons than protons.
Therefore, P³⁻ would have 15 protons and <em>18</em> electrons:
15 (+) + 18 (-) = 3 (-)
