For speed you can differentiate the equation, for acceleration you can again differentiate the equation .
at t=0 the particle is slowing down , when you get equation for velocity put t=0 then only -1 is left
Hi there!
A neutral metal sphere is comprised of both ELECTRONS and PROTONS.
Recall that electrons have a NEGATIVE (-) charge, and protons have a POSITIVE (+) charge.
Opposite charges attract, and like charges repel.
In this instance, the positively-charged rod will cause the electrons in the neutral metal sphere to move towards the side facing the rod (opposite charges attract), which causes the two to be attracted to one another.
Answer:
The greater the difference in electronegativity between two covalently bonded atoms, the greater the bond's percentage of ionic character.
Explanation:
Bond polarity (i.e the separation of electric charge along a bond) and ionic character (amount of electron sharing) increase with an increasing difference in electronegativity.
Therefore, we can say that, the greater the difference in electronegativity between two covalently bonded atoms, the greater the bond's percentage of ionic character.
Pressure = Force/ Area = 3000/2 = 1500 pascal.
Answer:
45 j
Explanation:
At the top, the KE will have been converted to PE
KE = 1/2 mv^2 =PEat-top = 1/2 10 *3^9 = 45 j
