A block is at rest on the incline shown in the gure. The coefficients of static and kinetic friction are 0.6 and 0.51, respec- t

Normal reaction force on the block while it is at rest on the inclined plane is given as

F_n = mgcos\theta

here we know that

m = 46 kg

\theta = 29^o

now we will have

F_n = 46*9.8*cos29 = 394.3 N

now the limiting friction or maximum value of static friction on the block will be given as

F_s = \mu_s * F_n

F_s = 0.6 * 394.3 = 236.56 N

Above value is the maximum value of force at which block will not slide

Now the weight of the block which is parallel to inclined plane is given as

F_{||} = mg sin\theta

here we know that

F_{||} = 46*9.8 sin29 = 218.55 N

Now since the weight of the block here is less than the value of limiting friction force and also the block is at rest then the frictional force on the block is static friction and it will just counter balance the weight of the block along the inclined plane.

So here <u>friction force on the given block will be same as its component on weight which is 218.55 N</u>

A plastic box has an initial volume of 2.00 m 3 . It is then submerged below the surface of a liquid and its volume decreases to
nikitadnepr [17]

Answer:

Volume strain is 0.02

Explanation:

Volume strain is defined as the change in volume to the original volume.

It is given that,

Initial volume of the plastic box is 2 m³

It is then submerged below the surface of a liquid and its volume decreases to 1.96 m³

We need to find the volume strain on the box. It is defined as the change in volume divided by the original volume. So,

\delta V=\dfrac{V_f-V_i}{V_i}\\\\\delta V=\dfrac{1.96-2}{2}\\\\\delta V=0.02

So, the volume strain on the box is 0.02.
