VP1. Consider the three connected objects shown in the figure below. Assume fırst that the inclined plane is frictionless and that the system is in equilibrium. In terms of m, g, and 6, find (a) the mass M and (b) the tensions T1 and T2. Now assume that the value of M is double the value found in part (a). Find (c) the acceleration of each object and (d) the tensions T, and T2. Next, assume that the coefficient of static friction between n and 2m and the inclined plane is µs and that the system is in equilibrium. Find (e) the maximum value of M and (f) the minimum value of M. (g) Compare the values of T2 when M has its minimum and maximum values. T2 T 2m M

Captive-bred trout reduce the fitness of wild populations. 1.0 0.8 0.6- 0.4 0.2 Relative fitness 0 Wild Captive Captive × Wild Wild Captive What can be said about the fitness of wild steelhead trout populations and captive-bred steelhead trout? (see figure above) The gene flow between hatchery-reared and wild populations is leading to a decline in fitness of wild populations. This data does not help us understand effects of gene flow on fitness. The gene flow between hatchery-reared and wild populations is neither helping nor hindering the fitness of the wild population. The gene flow between hatchery-reared and wild populations is increasing the fitness of the wild populations.

Explain the microscopic knob salad in detail?

Describe the CaF2 structure in terms of a host framework of one type of atom with selective occupancy of particular interstices in that framework by the other type of atom.

John Snow, an English physician, has observed that disease is becoming more prevalent in a local neighborhood and he wants to know why. He collects information about the local people, including how many family members contracted the disease and where they live. John discovers that the disease is most common in homes located closest to the town’s water pump. John contrives an explanation: that the illness is waterborne and people are contracting the disease from water they retrieve from the town’s water pump. After petitioning the authorities, the handle at the pump is removed. John collects data about disease incidence and finds that occurrence of the disease is greatly reduced. John concludes that the water from the pump was causing the illness.   What step(s) of the scientific method is/are missing from Data Table 1? Describe each and propose a way that they might be fulfilled in the scenario?
