The density of a metal block is 3.2 * 10^3 kg/m^3 and it's mass is 5.0 kg. what is the buoyant force (in newtons) acting on the metal block when it sinks in the water?

keep in mind the object is sinking not floating or

Determine the fraction of the magnitude of kinetic energy lost by a neutron (m1 = 1.01 u) when it collides head-on and elastically with a target particle at rest which is 21h (heavy hydrogen, m = 2.01 u).

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.

Which describes increasing the efficiency of energy resource
