A grandfather clock is controlled by a swinging brass pendulum that is 1.5 m long at a temperature of 30°C. (a) What is the length of the pendulum rod when the temperature drops to 0.0°C? (Give your answer to at least four significant figures.)  ___________mm (b) If a pendulum's period is given by  T  = 2?,where L is its length, does the change in length of the rod cause the clock to run fast or slow? fast /slow/ neither

A 2-meter-long steel rod has a diameter equal to 2.54 cm. By how much does the rod’s length change in meters if it’s heated from 318 degrees Kelvin to 460 degrees Kelvin? _________ m . You should get a really small answer, feel free to use exponential notation to express it.

We know from Newton's Law of Cooling that the rate at which an object warms up is proportional to the difference between the ambient temperature of the room and the temperature of the object. The differential equation corresponding to this situation is given by y' = k(M – y) where k is a positive constant. The solution to this equation is given by y = M + (yo – M)e-kt , where yo is the initial temperature of the object. Suppose your Thanksgiving turkey is kept at a temperature of 40 degrees Fahrenheit until it is put into a 350 degree Fahrenheit oven. It takes 2 hours for the turkey to warm up to a safe eating temperature of 165 degrees Fahrenheit. Find the values of yo, M, and k, for this situation, rounding your answers to 3 decimal places. Yo= M = k= Regardless of your answers above, suppose the k value in this situation is k = 0.3. Find the initial rate of increase of the turkey's temperature as soon as it is placed in the oven. Round to 3 decimal places. degrees per hour.

Suppose a walrus transfers energy by conduction through its blubber at the rate of 125 W when immersed in -1.25°C water. The walrus’s internal core temperature is 37.0°C, and it has a surface area of 1.85 m2. Chart attached. What is the average thickness of its blubber, in centimeters, which has the conductivity of fatty tissue?

An object has mass m, surface area A, temperature T, N molecules, and specific heat capacity c. The total thermal energy stored in the object is: Group of answer choices proportional to T^4 proportional to AT proportional to m proportional to cT proportional to NT

The temperature of a spere is raised in by 300˚C. The coefficient of volume expansion of the sphere is 47x10-6 C degree. By what percentage does volume increase? (a)3.22% (b)2.01% (c)1.41% (d)2.81%

A 6.00-m-long cylinder of solid aluminum has a radius of 3.00 cm. "If the cylinder is initially at a temperature of 7.00 C, how much will the length change when the temperature rises to 40.0°C? (Express your answer to three significant figures.) Submit m Due to the temperature increase, by how much (in %) would the density of the aluminum cylinder decrease? (Express your answer to three significant figures.) Submit % By what percentage does the volume of the cylinder increase? (Express your answer to three significant figures.) %

Note: Round off your answer up to 3 decimal places.  Input only the numerical value. Researchers are conducting a study to quantity the thermal conductivity of a composite material. A square box is made from 838 cm2 sheets of the composite insulating material that is 2.8 cm thick. A 201 W heater is placed inside the box. Sensors attached to the box show that the interior and exterior surfaces of one face have reached the constant temperatures of 81°C and 38°C. What is the thermal conductivity in W/m-K?

When the coefficient of linear expansion, a, and the temperature change, T-T, are large, a length L, of a solid substance expands in length to a(T, -T₂) L₁ = L₁e O L=L[1 + a(Tƒ– T;)]. ○ Ly=al (Ty-T). O L=L[1 + In(a(T₁-T))]. a(T, I₂ = ₁₂₁[ 1 + ª²(²₁-7)].
