So the corresponding answer for beta particle penetration in aluminum is:

$2.37 cm$

Firstly, it is known that aluminum stops beta particles, which is why penetration occurs. Thus, to calculate the depth of beta radiation in aluminum, it is given by the formula:

$P=\frac{m}{K}$

Where P is the given coefficient, K is the distance in cm and M is the mass of aluminum in grams.

$k=\frac{27}{11.4} \\k= 2.37 cm$

Kinematic equations are the equations that help to describe the motion of an object in constant acceleration. There are 4 of them and they are used in problems regarding motion when the variables are presented in them.

Ex:

Use V=Vo + at if you need to find velocity, and acceleration, time, and Vo are given to you

If a ball is thrown vertically upward with a velocity of 128 ft/s, then its height after t seconds is s = 128t − 16t2.

Fed [463]

Answer:

a) 256 ft

b) 32 ft/s

c) -32 ft/s

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration due to gravity = 32 ft/s²

$v^2-u^2=2as\\\Rightarrow s=\frac{v^2-u^2}{2a}\\\Rightarrow s=\frac{0^2-128^2}{2\times -32}\\\Rightarrow s=256\ ft$

Maximum height = 256 ft

When s = 240 ft

$v^2-u^2=2as\\\Rightarrow v=\sqrt{2as+u^2}\\\Rightarrow v=\sqrt{2\times -32\times 240+128^2}\\\Rightarrow v=32\ ft/s$

Speed of the ball at 240 ft is 32 ft/s while going up

Now this will be the velocity of the ball when it reaches 240 ft, which will be considered as the initial velocity

$v=u+at\\\Rightarrow 0=32-32t\\\Rightarrow t=\frac{-32}{-32}=1\ s$

Now, initial velocity will be considered as zero

$v^2-u^2=2as\\\Rightarrow v=\sqrt{2as+u^2}\\\Rightarrow v=\sqrt{2\times 32\times 16+0^2}\\\Rightarrow v=32\ ft/s$

Speed of the ball at 240 ft is -32 ft/s while going down

Romashka-Z-Leto [24]

Answer:

I=0.0361 kg.m^2

Explanation:

Torque is the rotational equivalent of a force

Torque= perpendicular distance r X Force F

Torque T = I(moment of inertia) X α (angular acceleration)

T= Iα

r= 0.0285m

F= 1.9 x 10^3

T=0.0285 x 1.9 x 10^3

T= 54.15Nm

I=T/α

I=54.15/150

I=0.361 kg.m^2
