natima [27]

Answer:

particle emit 4 unit of mass

Explanation:

Given data

Z > 92

americium-241

neptunium-237

to find out

subatomic particle is emitted from that decay process

solution

we have given that tiny amount decay from americium 241 to  neptunium 237

so total difference is here  (241- 237 ) = 4

so its mean this particle emit 4 unit of mass.

and we say that radioactive substance americium 241 emit alpha rays during decay process

A helicopter blade spins at exactly 180 revolutions per minute. Its tip is 10.00 m from the center of rotation. What is its aver
olya-2409 [2.1K]

Answer:

5.8E-3m/s

Explanation:

Using

V= d/t

V= velocity

d= distance

t= time

But d= 2πr

But 180rev= 1min

So 1min/180= 60s/180

So

Vavr= 2π(10m)/180*60

=5.8E-3m/s

Why can the function y=-16x^2+v0t+h0be used to determine the object's moving distance? Are there any limitations and special con
dolphi86 [110]
You could research the derivation of it, it incorporates velocity and height and produces a quadratic function of time. very useful, it may be limited to its domain which should theoretically range from 0 to t but if it has a negative root then you use y-int as initial height so not any limitations I know abt
