Communicate is the answer

**Answer:**

The force needed will be greater to hold the object at rest.

**Explanation:**

For a better understanding let's take a look at the attached image.

In the image there is an example of this condition, we have an object of 3 kg-f mass, the first angle between the horizontal and the inclined plane is 35°. When we increase the angle to 45°. We can realize that we need to hold the object with a stronger force.

The calculation and the equations based on Newton's laws can be found in the attached image.

**Answer:**

0.365 cm³

**Explanation:**

The change in volume is found by multiplying the coefficient of expansion by the volume and the temperature change. The temperature change is in °F, but the expansion coefficient is per °C, so we need to convert the temperature scale in the computation.

ΔV = V·Ce·ΔT

= (π/6·d³)(1.5×10⁻⁶/°C)((5 °C)/(9 °F))(305 °F)

= (1436.76 cm³)(1.5×10⁻⁶/°C)(169.44 °C)

= **0.365 cm³ . . . . increase in volume**
