Answer:

Alpha is the least penetrating radiation listed below.

Gamma is the most penetrating radiation in the given list.

These rays can be used to detect cancer, sterilizing the medical instrument, smoke detector, etc.

Radiation emitted from the radioactive elements also have very harmful. They affect the living being a lot. Waste from the nuclear reactor also contains harmful radiation which causes Land pollution if not disposed of properly.

How to calculate final speed when the mass is 40,000kg height id 2.5km and 500,000N of force
Tju [1.3M]

The final speed when the mass is 40,000kg height is 2.5km and 500,000N of force is 176.8 m / s

According to Newton's second law of motion,

F = m a

F = Force

m = Mass

a = Acceleration

m = 40000 kg

F = 500000 N

a = F / m

a = 500000 / 40000

a = 12.5 m / s²

a = v / t

v = d / t

v = Velocity

t = Time

d = Distance

d = 2.5 km = 2500 m

a = d / t²

12.5 = 2500 / t²

t² = 200

t = 14.14 s

v = 2500 / 14.14

v = 176.8 m / s

Therefore, the final speed is 176.8 m / s

zalisa [80]

Answer:

It will have the same KE ( 450 J ) just before it hits the ground. The GPE transferred to KE is the same in both cases and the original KE is the same in both cases so the total will be the same.

The one thrown sideways will take longer to get to the ground but it will have the   same   velocity ( and therefore KE ) as the       thrown down stone.
