You have a grindstone (a disk) that is 98.0 kg, has a 0.335-m radius, and is turning at 100 rpm, and you press a steel axe again

Alika [10]

Answer:

$a=0.276$

Explanation:

From the question we are told that:

Mass $m=98.kg$

Radius $r=0.335$

Angular velocity $\omega=100rpm$

Radial force of $F_r=23.6 N.$

Kinetic coefficient of friction $\mu=0.192$

Generally the equation for Kinetic Force is mathematically given by

$F_k=\mu.F_r$

$F_k=0.192*23.6$

$F_k=4.5312$

Generally the equation for Torque on Center is mathematically given by

$Ia=f_k*r$

Where

$I=\frac{Mr^2}{2}$

Therefore

$a=\frac{2f_k}{Mr}$

$a=\frac{2*4.5312}{98*0.335}$

$a=0.276$

Therefore Angular acceleration of the grindstone is

$a=0.276$

What is the net force when forces applied are 300 N to the right and 100 N to the right

labwork [276]

Answer:

400 Newtons to the right.

Explanation:

You have 300 Newtons that are being applied to the right and you also 100 Newtons to the right. When calculating net force with the forces that go the same direction, you add them. 300 plus 100 is 400. Therefore, it is 400 Newtons or N to the right. Hope this helps!

The gravitational force between two spheres in outer space is 1000 n. how large would this force be if the mass of each sphere w

kipiarov [429]

The force will remain same if the mass of each sphere is doubled and the distance between them is doubled as well.

The force of gravitation between two spheres is given by

$f=\frac{G m1 m2}{r^{2}}$
