a block is 2cm wide, 5.4cm deep, and 3.1cm long. the density of the block is 8.5g/cm. what is the mass of the blocks?

1 answer:

3 0

We know, density = mass / volume
Here, d = 8.5 g/cm³
v = 2 * 5.4 * 3.1 = 33.48 cm³

Substitute their values,
m = 8.5 * 33.48
m = 284.58 g

In short, Your Answer would be 284.58 g

Hope this helps!

Answer:

Part a)

$T_L = 155.4 N$

Part b)

$T_R = 379 N$

Explanation:

As we know that mountain climber is at rest so net force on it must be zero

So we will have force balance in X direction

$T_L cos65 = T_R cos80$

$T_L = 0.41 T_R$

now we will have force balance in Y direction

$mg = T_L sin65 + T_Rsin80$

$514 = 0.906T_L + 0.985T_R$

Part a)

so from above equations we have

$514 = 0.906T_L + 0.985(\frac{T_L}{0.41})$

$514 = 3.3 T_L$

$T_L = 155.4 N$

Part b)

Now for tension in right string we will have

$T_R = \frac{T_L}{0.41}$

$T_R = 379 N$
