Aman stands on the roof of a building of height 13.0and throws a rock with a velocity of magnitude 30.0 at an angle of 34.9 above the horizontal. you can ignore air resistance.(a) calculate the maximum height above the roof reached by the rock. take free fall acceleration to be 9.80(b) calculate the magnitude of the velocity of the rock just before it strikes the ground. take free fall acceleration to be 9.80(c) calculate the horizontal distance from the base of the building to the point where the rock strikes the ground. take free fall acceleration to be 9.80

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error

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.
