96%

114 rated

Answer

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

Step 2

Which sentence describes the relationship between weight and mass?

99%

104 rated

Answer

The correct relationship between weight and mass is that Weight is directly proportional to mass.

Step 3

Determine the mass of 1 orange.

Answer

Given all 5 oranges have the same mass and together they weigh 1.1 kg, the mass of 1 orange is calculated as follows:

ext{Mass} = rac{ ext{Total mass}}{ ext{Number of oranges}} = rac{1.1 ext{ kg}}{5} = 0.22 ext{ kg}

Step 4

Calculate the weight of 1 orange. Use the equation: weight = mass × gravitational field strength.

The weight of 1 orange can be calculated using:

extWeight=extMassimesextGravitationalfieldstrength=0.22extkgimes9.8extN/kg=2.156extNext(roundedto2.16extN) ext{Weight} = ext{Mass} imes ext{Gravitational field strength} = 0.22 ext{ kg} imes 9.8 ext{ N/kg} = 2.156 ext{ N} ext{ (rounded to } 2.16 ext{ N)}

Step 5

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

97%

117 rated

Answer

The correct answer for the extension of the spring is 0.015 m.

Step 6

Calculate the spring constant of the spring. Use the equation: spring constant = force / extension.

Answer

To calculate the spring constant, we use the formula:

ext{Spring constant} = rac{ ext{Force}}{ ext{Extension}} = rac{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?

96%

Answer

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