A 4.0 kg block is pushed along a horizontal floor by a force F→ of magnitude 26 N at a downward angle θ = 40°. The coefficient of kinetic friction between the block and the floor is 0.24. Calculate the magnitudes of (a) the frictional force on the block from the floor and (b) the block’s acceleration.

Will give brainliest! which statement best describes the difference between strong nuclear forces and weak nuclear forces? weak nuclear forces are involved when certain types of atoms break down. strong nuclear forces are responsible for holding atoms' nucleus together. weak nuclear forces hold bonds between atoms together. strong nuclear forces hold together the nucleus of an atom. strong nuclear bonds prevent atoms from falling apart. weak nuclear bonds prevent compounds from falling apart. strong nuclear forces are involved in breaking electrons from their shells. weak nuclear forces hold protons in the nucleus.
