96%

114 rated

Answer

The name given to point X in Figure 6 is the centre of mass.

Step 2

Which sentence describes the relationship between weight and mass?

99%

104 rated

Answer

The correct statement is that weight is directly proportional to mass.

Step 3

Determine the mass of 1 orange.

Answer

Given that the total mass of 5 oranges is 1.1 kg, the mass of 1 orange can be calculated as follows:

extMass=1.1extkg5=0.22extkg ext{Mass} = \frac{1.1 ext{ kg}}{5} = 0.22 ext{ kg}

Step 4

Calculate the weight of 1 orange.

Answer

Using the equation for weight:

extweight=extmass×extgravitationalfieldstrength=0.22extkg×9.8extN/kg=2.156extN ext{weight} = ext{mass} \times ext{gravitational field strength} = 0.22 ext{ kg} \times 9.8 ext{ N/kg} = 2.156 ext{ N}

The weight of 1 orange is therefore 2.156 N.

Step 5

What is the extension of the spring when a force of 6.0 N acts on it?

Answer

The extension of the spring when a force of 6.0 N acts on it is 0.015 m.

Step 6

Calculate the spring constant of the spring.

Answer

The spring constant can be calculated using the equation:

extspringconstant=forceextension=6.0extN0.015extm=400extN/m ext{spring constant} = \frac{\text{force}}{\text{extension}} = \frac{6.0 ext{ N}}{0.015 ext{ m}} = 400 ext{ N/m}

Step 7

What will happen to the spring when the force is removed?

Answer

When the force is removed, the spring will return to its original shape, demonstrating its elastic properties.
