If an object is not moving are the forces acting on it balanced? Yes or no?why?

Physics

xxMikexx [17]3 years ago
6 0

This is another time to look at Newton's 2nd law of motion:

Net Force = (mass) x (acceleration)

If the object is not moving, then its acceleration is certainly zero, and Newton's law looks like this:

Net Force = (mass) x (zero)

or  Net Force = (zero) .

"Net Force = zero" means that if there ARE any forces acting on the object, then they add up to zero, and we call them "balanced" forces.

So the answer is '<em>yes</em>', and that's why.

nirvana33 [79]

Answer:

The average speed will be 1.5km/hr .

Explanation:

Distance need to be traveled = 7.5Km

Time taken = 5 hours

Average speed refers to total distance traveled with respect to total time taken .

It can be calculated as given below :

Average speed =total distance /total time taken

Substituting the values we get ,as shown below

Average speed =7.5/5=75/50

Average speed = 1.5 Km/hr

A viscous liquid is sheared between two parallel disks of radius �, one of which rotates with angular speed Ω, while the other i
Alexus [3.1K]

Answer:

Upper disk rotates at a constant angular velocity. The velocity at any height from stationery disk, say at x metres

U_o=v(\frac {x}{h}) where v is tangential velocity at radius r from the centre of disk

U_o=r\omega (\frac {x}{h})

The radial component of velocity is given as

U_r=0

The z component of velocity is also given as  

W=0

Total velocity, v= r\omega (\frac {x}{h})\hat e_{o}

12. A measuring cylinder has 150ml. of water in it. When a stone is immersed into the measuring cylinder, the water level raised
skelet666 [1.2K]

Answer:

60ml

Explanation:

I'm going to assume you mean 210ml not centimeters. To find the volume all we do is subtract both values or with the formula [ f - i = v ]  where f = final amount and i = initial amount.

210 - 150 = 60ml

Best of Luck!
