Express your answer in 3 decimal places.You left a rectangular piece of steel on the ground when the temperature was 78.0°F. Later you returned when the temperature was 105.0°.The dimensions are 30 m ✕ 40 m. Calculate the change in the area of the metal. Take ? for steel to be 1.2 10-5/K.The solar panels are placed in an optimal position such that they receive a solar power of 1186kWh/m^2 per year1. The average solar cell has an efficiency of 20% and an average household in the Netherlands uses 2990kWh of electricity per year. The average solar panel has dimensions of 165x99cm.

'6.76x1024 atoms 9.9x1024 atoms Od 9.9×1030 atoms1.21 A team is designing a helium-filled balloon that will fly to an altitude of 80,000 ft. As the balloon ascends, the upward force (buoyant force) will need to exceed the total weight. Thus, weight is critical. Estimate the weight (in newtons) of the helium inside the balloon. The balloon is inflated at a site where the atmospheric pressure is 0.89 bar and the temperature is 22°C. When inflated prior to launch, the balloon is spherical (radius 1.3 m) and the inflation pressure equals the local atmospheric pressure.69 ◦F is considered room temperature, what is this in ◦C, R, and K
