1. Dois termômetros, um graduado na escala Celsius e
outro na escala Fahrenheit fornecem a mesma leitura
para a temperatura de um gás. Determine o valor dessa
temperatura.
2. Uma certa escala termométrica adota os valores de -20
para o ponto de fusão do gelo e 580 para a ebulição da
água líquida. Determine:
A. a fórmula de conversão entre as duas escalas;
b. a indicação dessa escala que corresponde a

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .
