A 95 N force exerted at the end of a 0.50 m long torque wrench gives rise to a torque of 15 N · m. What is the angle (assumed to

o-na [289]

Answer:

angle = 18.40 degree

Explanation:

given data

force = 95 N

distance = 0.50 m

torque = 15 N · m

to find out

angle between the wrench handle and the direction of the applied force

solution

we will apply here torque equation that is express as

torque = distance × force × sin(θ) ...................1

put here value we will get angle that is

15 = 0.50 × 95 × sin(θ)

sin(θ) = 0.315789

θ = 18.40 degree

A rock is placed on a balance and its mass is determined as 18.3 g. When the rock is then placed in a graduated cylinder that or

Crank

Answer : The density of rock reported should be, 3.1 g/mL

Explanation :

Mass of rock = 18.3 g

Original volume of water = 11.1 mL

New volume of water = 17.0 mL

First we have to calculate the volume of rock.

Volume of rock = New volume of water - Original volume of water

Volume of rock = 17.0 mL - 11.1 mL

Volume of rock = 5.9 mL

Now we have to determine the density of rock.

Formula used :

$\text{Density of rock}=\frac{\text{Mass of rock}}{\text{Volume of rock}}$

$\text{Density of rock}=\frac{18.3g}{5.9mL}=3.1g.mL$

Thus, the density of rock reported should be, 3.1 g/mL
