10. A 40 kg mass is attached to one end of a spring, which has a spring constant of 700 N/m. The other end of the spring is attached to the bottom of a full tank of water. The mass has a volume of 0.25 m3 and is completely submerged in the water.a. Will the mass float, sink, or remain stationary?b. If the mass sinks or floats, determine how far the spring will compress or stretch?

5. DETAILS 777777.78 Pa MY NOTES A 70.00kg ballroom dancer wearing high heels accidentally steps on her partner's foot. If her entire weight was momentarily supported by the heel of her shoe, which has a surface area of 0.90 cm², what amount of pressure does this apply to her partner's foot? 762.22 Pa 76222.22 Pa 7622222.22 Pa ASK YOUR TEACHER Suppose she instead stepped on her partner's foot with her forefoot instead of her heel (i.e., larger surface area). Would the pressure on her partner's foot be greater, less than, or equal to if she stepped on her partner with her heel? The pressure from the forefoot would be greater than the pressure from her heel. The pressure from the forefoot would be equal to the pressure from her heel. The pressure from the forefoot would be less than the pressure from her heel.

1. What factors need to be taken into account when designing inflatable devices that float on water? Explain at least one factor relating to the gas itself, and at least one factor relating to the material holding the gas.
