WebAn approximation of its density is ρ (r) = (A − B r), where A = 1 2 7 0 0 k g / m 3, B = 1. 5 0 × 1 0 − 3 k g / m 3 and r is the distance from the centre of earth. Use R = 6 . 4 × 1 0 6 m … WebDec 27, 2024 · If you're dealing with gravitational potential energy over short distances, such as with ramps on the Earth's surface, where g=9.81ms −2, use E grav = mgh. … pender woods at cane bay by starlight homes

WebThe spring has negligible mass and a spring constant k0 , as shown in Figure 1. When an object of mass m0 is released from rest above the spring, the object falls and then makes contact with the top of the spring with a speed v0 , as shown in Figure 2. The spring then compresses such that the object reaches a position x0 below the spring's ... WebV i n s i d e = 2 R 3 − G M (3 R 2 − x 2) (x < R) V s u r f a c e = R − G M (x = R) V o u t s i d e = x − G M (x > R) Therefore from these three equations if we draw the graph of potential vs distance r from the centre of the sphere, then it would look like fig in (B). WebThe kinetic energy of the spring is equal to its elastic potential energy, i.e. 1/2mv^2 = 1/2kx^2 when the spring is stretched some distance x from the equilibrium point and when its mass also has some velocity, v, with which it is moving. This occurs somewhere in between the equilibrium point and the extreme point (extreme point is when x ... media blast cabinet not working
