Answer:

D

Explanation:

F=ma

a=F/m

according to option D, F is constant

so acceleration is inversely proportional to mass and A has half the mass of B. Hence, acceleration of A will be twice of B if same force is applied.

Solve for x. 4(x+1)≤4x+3
alexdok [17]
4x + 4 < 4x + 3 (expand it)
4 < 3 (cancel 4x on both sides)
Since 4 < 3 is not true there is no solution.

A machine part has the shape of a solid uniform sphere of mass 245 g and diameter 4.30 cm . It is spinning about a frictionless
Alla [95]

Answer:

Angular acceleration, \alpha =9.49\ rad/s^2

Explanation:

It is given that,

Mass of the solid sphere, m = 245 g = 0.245 kg

Diameter of the sphere, d = 4.3 cm = 0.043 m

Radius, r = 0.0215 m

Force acting at a point, F = 0.02 N

Let \alpha is its angular acceleration. The relation between the angular acceleration and the torque is given by :

\tau=I\times \alpha

I is the moment of inertia of the solid sphere

For a solid sphere, I=\dfrac{2}{5}mr^2

\alpha =\dfrac{\tau}{I}

\alpha =\dfrac{F.r}{(2/5)mr^2}

\alpha =\dfrac{5F}{2mr}

\alpha =\dfrac{5\times 0.02}{2\times 0.245\times 0.0215}

\alpha =9.49\ rad/s^2

So, its angular acceleration is 9.49\ rad/s^2. Hence, this is the required solution.
