We want the reaction 188o + 11h --> 189f + 10h. what is the q-value of this reaction? is it endo- or exo-thermic? (m180=17.999161 u, mh=1.008665 u, mh=1.007825 u, m18f=18.000938 u ; all atomic masses, except neutron)
give mev.
do 10mev protons provide enough energy to drive this reaction?

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

explanation:

asthenosphere and convection

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j

b. false

explanation:

suppose a rock in free fall is dropped off a cliff. after falling for 5 seconds, its speed would not be 100 m/s.
