Neutrons < Cosmic radiation < Gamma rays < beta particles < Alpha particles
Explanation:
Alpha particles are the most energetic of the nuclear radiations produced in nuclear reactions.
Neutrons are radiations with no charges on them. They are the lowest radiation in terms of energy.
Cosmic radiation are energetic radiations usually produced when solar radiation interacts with the atmosphere.
Gamma ray is a form of electromagnetic radiation with no mass and charge.
Beta particles are of two types. The negative and positive beta particles. Negative beta particles are called negatrons and they carry negative charges while positrons carry positive charges.
Alpha particles are similar to Helium atom,they are the most energetic of all the radiations.

False it’s the unit of force
Answer:
mature man means giving up the need to conquer and vanquish and being okay with letting others get their way.
Explanation:
Answer:
Explanation:
There will be reaction force by each vertical post on horizontal plank . Let it be R₁ and R₂ . R₁ is reaction force by the post nearer to woman
Taking torque of all forces about the end far away from the woman
Torque by reaction force = R₁ x 5.5
= 5.5 R₁ upwards
Torque by weight of woman in opposite direction , downwards
= - 804 x ( 5.5 - 1.55 )
= - 3175.8
Torque by weight of the plank in opposite direction , downwards .
= - 27 x 5.5 / 2
= - 74.25
Torque by R₂ will be zero as it passes through the point about which torque is being taken .
Total torque
= 5.5 R₁ - - 3175.8 - - 74.25 = 0 ( For equilibrium )
5.5 R₁ = 3250
R₁ = 590.9 N .
Answer:
You should generally have one independent variable in an experiment. This is because it is the variable you are changing in order to observe the effects it has on the other variables.
HOPE THIS HELPED!!!!!!!!!!!!XDDDDDDDDD
