Buoyancy is the ability of an object to float. Archimedes' Principle states that the buoyant force is equal to the weight of the fluid that is displaced by the submerged object. The buoyant force can be computed by

- The spring in the figure below is stretched from its equilibrium position at x = 0 to a positive coordinate xo. ko HINT x = 0 x = xo PE sn PE 50 The force on the spring is F and it stores elastic potential energy PESO. If the spring displacement is tripled to 3x, determine the ratio of the new force to the original force, and the ratio of the new to the original elastic potential energy, Fo Fo PESO (a) the ratio of the new force to the original force, PE ST PE SO (b) the ratio of the new to the original elastic potential energy,arrow_forwardTwo small charged objects attract each other with a force F when separated by a distance d.If the charge on each object is reduced to one-fourth of its original value and the distance between them is reduced to d/2,the force becomes?arrow_forwardA simple pendulum of length L, has a maximum angular displacement e_max. At one point in its motion, its kinetic energy is K = 3 J and its potential energy is U = 4.2 J. When the pendulum's angular velocity is one-fourth its maximum value (0' = %3D O'_max/4), then its kinetic energy is:arrow_forward
- A vertical tower stands on a horizontal plane and is surmounted by a vertical flag-staff of height 6 m. At a point on the plane, the angle of elevation of the bottom and top of the flag-staff are 30° and 45° respectively. Find the height of the tower.

Find: a. the average velocity between t = 1 8 and ty= 3 s. b. the velocity at t = 2 s. b. the acceleration at t = 4 s.arrow_forwardA standard science experiment is to drop a ball and see how high it bounces. Once the “bounciness” of the ball has been determined, the ratio gives a bounciness index. For example, if a ball dropped from a height of 10 feet bounces 6 feet high, the index is 0.6 and the total distance traveled by the ball is 16 feet after one bounce. If the ball were to continue bouncing, the distance after two bounces would be 10 ft + 6 ft + 6 ft + 3.6 ft = 25.6 ft. Note that distance traveled for each successive bounce is the distance to the floor plus 0.6 of that distance as the ball comes back up. Write a program that lets the user enter the initial height of the ball and the number of times the ball is allowed to continue bouncing. Output should be the total distance traveled by the ball. Please name your function "bounce" that has three arguments (initial height, index, number of bounce) and return the total distance traveled by the ball.

- Bessel Function ZerosMatlab codearrow_forwardIn matlab code Find the velocity of mars, earth, venus. In the descent phase of an extraterrestrial space mission, a spacecraft free falls through the planet's atmosphere. As it falls, it will reach a constant or terminal velocity when the air resistance force balances the gravitational attraction force. The terminal velocity is given by V₁ = where m is the spacecraft's mass [m], g is the acceleration due to gravity on the planet, p is the atmosphere's density [kg/m³], Cp is the spacecraft's drag coefficient, and A is the spacecraft's cross-sectional area [m²]. a) Write a function named terminalVelocity which calculates the terminal velocity an object. The function should . 2mg pCDA input m, g, p, CD, and A output the terminal velocity b) Write a program named q03.m which calculates the terminal velocity of a spacecraft at 10 km above the surface of various planets.

Read the values for 2 circles- x1, y1, r1 for C1 and x2, y2, r2 for C2. (i) Determine whether the 2 circles intersect. To solve the problem it suffices to check if the distance between the 2 centers is lesser than the sum of radii of the 2 circles.
