A farmer wants to fence off his four-sided plot of flat land. He measures the first three sides, shown as A, B, and C in Figure 16, and then correctly calculates the length and orientation of the fourth side D. What is his result?

A rectangle has a length of (2.8 ± 0.2) m and a width of (1.7 ± 0.2) m. Calculate the area and the perimeter of the rectangle, and give the uncertainty in each value. (a) Calculate the area and give its uncertainty. (Enter your answers in m2.)   m2 ±  m2 (b) Calculate the perimeter of the rectangle and give its uncertainty. (Enter your answers in m.)   m ±  m

The answer seems incorrect. Maybe it's because of multiplying wrong angles while calculating the x and y components. Please recheck and correct the answer.

Problem 13:   In this problem, the symbols M, L, and T represent the dimensions mass, length, and time, respectively. Consider the physical quantities s, v, a, and t with dimensions [s] = L, [v] = LT-1, [a] = LT-2, and [t] = T. (Here, the square bracket means “the dimensions of” so, for example, [s] represents the dimensions of the quantity s.) Part (a)  What is the simplest expression involving only a and s that has the same dimensions as v2?  expression = ______ Part (b)  What is the simplest expression involving only v and t that has the same dimensions as a?  expression = ______ Part (c)  What is the simplest expression involving only v and t that has the same dimensions as s?  expression = ______ Part (d)  What is the simplest expression involving only a and t that has the same dimensions as s? expression = ______

A person walks 4 m to the park, then he walks 8200 km in the park then he returns back to home after grocery shopping and covers 720 cm, how much total distance that person covers in m?

A surveyor needs to find the distance across a straight river. Markers are set up at points A and B on opposite sides of the river (see diagram), and at point CC that is 290 feet from B, the angle C is measured and found to be 45∘19.8′You may assume angle B is a right angle. The distance from A to B is  feet.
