we know if we apply the force along the left, friction acts along the right and vice versa.But what about an object which is not

moving but at rest on a surface?​

Answer:

<em>Explanation below</em>

Explanation:

<u>Friction Force</u>

When two objects are in contact, the surface between them exerts a frictional force as long as the objects are tried to move with respect to each other.

If a given external force is applied to the left, then a friction force appears to the right and opposes the intent to move them. A similar situation occurs when the force is applied to the right side.

If the object is at rest and no force is applied, no friction force appears.

It's important to recall that two different friction forces are defined: the kinetic friction force and the static friction force, usually the latter is greater than the first.

The distance and direction between starting and ending positions​
rodikova [14]

Answer:

The length traveled by an object moving in any direction or even changing direction is called distance. The location of an object in a frame of reference is called position. For straight line motion, positions can be shown using a number line. The separation between original and final position is called displacement

What two quantities do you have to know to calculate the density of and object?
charle [14.2K]
'Density' is defined as (mass) / (volume). You need enough information to be able to measure or calculate the mass and the volume of the object.

Noise-canceling headphones are an application of destructive interference. Each side of the headphones uses a microphone to pick
exis [7]
The question for this problem would be the minimum headphone delay, in ms, that will cancel this noise.
The 200 Hz. period = (1/200) = 0.005 sec. It will need to be delayed by 1/2, so 0.005/2, that is = 0.0025 sec. So converting sec to ms, will give us the delay of:Delay = 2.5 ms.

What force, in newtons, must you exert on the balloon with your hands to create a gauge pressure of 62.5 cm H2O, if you squeeze
yulyashka [42]

Answer:54.70 N

Explanation:

Given

Gauge Pressure of 62.5 cm of H_2O

i.e. h=62.5 cm =0.625 m

Effective area A=51 cm^2

initial Pressure= 1 atm=101.325 kPa

Gauge Pressure P=\rho gh

\rho =density\ of\ water =1000 kg/m^3

P_{gauge}=1000\times 9.8\times 0.625=5.937 kPa

Force creates a pressure of P_1 which will be equal to Gauge Pressure

P_1=\frac{F}{A}

P_1=P_{gauge}

\frac{F}{A}=5.937 kPa

F=5.937\times 51\times 10^{-4}\times 10^3

F=30.27 N
