- Find A x B and the angle between A and B, given that A = −13ĵ + 11k and B = A x B = Ꮎ = X Review the cross product and check your calculations. -15î + 10ĵ.A closed water tank has the form of a cuboid with a square base with sides of length x and a height h. The total surface area of the tank is 16000 cm2 Find the value of x which maximises the volume. Give your answer correct to 2 decimal places.North Pole equator South Pole The sketch is a cross section through the earth, showing two points that have a difference in latitude of angle 0. The mean radius R of the earth is 6.371 × 10°meters. A nautical mile is defined as 1852 meters exactly. Using these ,calculate how many nautical miles there are betw two points on n's surface that have the same longitude but have latitudes that differ by 1.000 degree. (Just in case: the definition of angle, in radians, is the arc of a circle it subtends divided by the radius of the circle. A circle is 27 radians or 360°.) There are = nautical miles between two points with latitudes differing by 1.000°. (Enter your answer as a number, without exponents and without units, but with appropriate significant figures.)
- In the diagram below there is a thick-walled cylindrical tube. Its height is H = 5.0 m, its inner radius is R1 = 1.0 m, its outer radius is R2 = 3.0 m and its mass is M = 10.0 kg. The volume density is proportional to the square of the height h measured from the top of the cylinder: p x h?. R2 a) Proof that the proportionality constant k (p = kh?) is k = , ms 100m b) Determine the position of the center of mass of this object. c) Determine I, the moment of inertia of the cylindrical tube around the axle going through the center of the top (as shown on diagram). You can use lying =mr? (the rotational inertia of a ring of radius r and mass m rotating around an axis parallel to it, through its center).Please answer this. Thank youHi I need help here please
