Answer:
Explanation:
There are 4 forces. These are 1) Gravity, 2) Weak Nuclear Force, 3) Electromagnetism, and 4) Strong Nuclear Force.
Order of strength from weakest to strongest: Gravity, Weak Nuclear Force, Electromagnetism, Strong Nuclear Force
Type of Range:
Gravity - Unlimited range
Weak Nuclear Force - Limited range
Electromagnetism - Infinite range
Strong Nuclear Force - Limited Range
Found in:
Gravity - Exists between all objects with mass
Weak Nuclear Force - Governs over beta decays like the emission of electron or positron
Electromagnetism - the attraction found between particles that are electrically charged
Strong Nuclear Force - Found in atoms and subatomic particles. It is responsible for holding the atoms' nucleus together.
Answer:
kinetic
Explanation:
i just remember it from last year
Answer
given,
Pressure on the top wing = 265 m/s
speed of underneath wings = 234 m/s
mass of the airplane = 7.2 × 10³ kg
density of air = 1.29 kg/m³
using Bernoulli's equation




Applying newtons second law
2 Δ P x A - mg = 0


A = 3.53 m²
As we know that KE and PE is same at a given position
so we will have as a function of position given as

also the PE is given as function of position as

now it is given that
KE = PE
now we will have




so the position is 0.707 times of amplitude when KE and PE will be same
Part b)
KE of SHO at x = A/3
we can use the formula

now to find the fraction of kinetic energy



now since total energy is sum of KE and PE
so fraction of PE at the same position will be


That is called pseudoscience
