What changes would occur if a person moved from a cold swimming pool to a very warm changing room?
When a person moves from a cold swimming pool to a very warm changing room then the changes are :
a) During cold temperature environment skeletal muscles contract rapidly and shivering where skin hairs stand upright takes place that involve in release of heat for homeostasis. Hence vasoconstriction takes place.
But when shifted to very warm changing room sweating increases where heat is dissipated out through sweat and blood vessels become wider which allow more heat to be lost to the surroundings. Hence vasodilation takes place and people stop shivering.
This thermal regulation is regulated by thermal regulatory center present in the hypothalamus of the brain where thermoreceptors are activated based on the surroundings temperature.

A person is swimming 0.91 m beneath the surface of the water in a swimming pool. A child standing on the diving board drops a ball into the pool directly above the swimmer. The swimmer sees the ball dropped from a height of 5.4 m above the water. From what height was the ball actually dropped?
A person is swimming 0.87 m beneath the surface of the water in a swimming pool. A child standing on the diving board drops a ball into the pool directly above the swimmer. The swimmer sees the ball dropped from a height of 5.3 m above the water. Part A From what height was the ball actually dropped?
To a person swimming 0.815 m beneath the surface of the water in a swimming pool, the diving board directly overhead appears to be a height of 5.00 m above the swimmer. 1.) What is the actual height of the diving board above the surface of the water?
For the kids jumping into the swimming pool, what type of heat transfer did they experience when they found that the water was cold? O Conduction O Convection O Radiation
You are standing in a 1.5-m-deep swimming pool at night. The water is very still. You hold a laser pointer just above the water's surface and shine it nearly parallel to the surface, but tilted slightly down so that the beam enters the water 3.5mfrom you. How far from you does the beam strike the bottom of the pool? Index of refraction of the water is 1.33.
You are at the bottom of your swimming pool, shining a flashlight upwards. What angle would you have to shine the light; relative to the surface of the water, for the light to emerge parallel to the surface (n = 1.3)? Anwer in degrees.
In the figure, a 2.0-m-long vertical pole extends from the bottom of a swimming pool to a point 50.0 cm above the water. Sunlight is incident at angle θ = 50.0°. What is the length in meters of the shadow of the pole on the level bottom of the pool? The water has an index of refraction of 1.33.
A 9.00 m × 14.0 m swimming pool slopes linearly from a 1.10 m depth at one end to a 3.00 m depth at the other. Part A What is the mass of water in the pool? Express your answer with the appropriate units. =kg
In the figure, a 1.8-m-long vertical pole extends from the bottom of a swimming pool to a point 50.0 cm above the water. Sunlight is incident at angle θ = 48.0°. What is the length in meters of the shadow of the pole on the level bottom of the pool? The water has an index of refraction of 1.33. Blocked Sunrays
5. A small swimming pool is contaminated with a pesticide from the nearby agricultural run-off with a concentration of C. Initially, at t = 0, a special faucet opens pouring in clean water at a constant rate Q. The drain is also simultaneously opened so the pool is draining at rate Q as well. Volume of the pool is constant. a) Derive an equation to predict the pesticide concentration for t > 0. b) What is the steady-state pesticide concentration...
