You place a solid cylinder of mass M on a ramp that is inclined at an angle β to the horizontal. The coefficient of static frict
zlopas [31]

Answer:

Explanation:

Let the frictional force required be f .

frictional force is responsible in creating rotational motion in the cylinder.

torque created by frictional force = f R

if angular acceleration be α

α = f R / I , I is moment of inertia of cylinder .

α = a / R , a is linear acceleration.

f R / I = a / R

a = f R² / I

linear acceleration a of cylinder down the slope

ma = mgsinθ - f  , ( f force is acting upwards and mgsinθ is acting downwards )

mf R² / I = mgsinθ -f

f ( m R² / I + 1) = mgsinθ

f = mgsinθ / ( m R² / I + 1)

= mgsinθ / ( m R² / mk² + 1) , k is radius of gyration of cylinder.

= mgsinθ / (  R² / k² + 1)

Putting the given values

f = Mgsinβ /(  R² / k² + 1)

for cylinder ,  R² / k² = 2

f =  Mgsinβ /3

What will happen to this current if a magnet is brought near the cord? A. It will exert a force on the voltage. B. The electric
Andreyy89

Answer:

The correct answer is D)

Explanation:

When an electric magnet is brought near a cord with an electric current, the cord will most likely deflect away from the magnet because electric fields flowing through a wire generates its own magnetic field.

ruto is 12 years old.in three years time he will be ⅓ of his father present age.how old was his father 12 years ago​
max2010maxim [7]

Answer: 33

Explanation:

12+3=15, so in 3 years time Ruto will be 15.

Because 15 is said to be 1/3 times his fathers present age (x), you can plug that into an equation.

15=1/3(x)

Then solve the equation.

(3)15=[1/3(x)]•3

45=x

His father is currently 45, so if you subtract 12 from that, you get 33.

Ruto’s father was 33 years old 12 years ago.
