The energy added here is potential energy since it is moving upward 180 meters in a gravitational field. This is then turned into KE when it rolls down. 2524N x 180m = 454,320J
Answer:
yes it is essential
Explanation:
a switch is an electrical component that can disconnect or connect the conducting path in an electrical circuit; controls current flow into a circuit
At a certain location, the horizontal component of the earth’s magnetic field is, due north<span>. A proton moves eastward with just the right speed, so the magnetic force on it balances its weight.

Answer:
Energy
Explanation:
The unit is
.
We can see the formula of kinetic energy is

Where
is the mass and
is the velocity of the object.
Which means its unit would be kg times square of meter per second, that is
. Which is often referred as Joule.
Also, when look at the formula of work done by an object.

Where
is the force and
is the distance traveled by the object due to force
.
We an see that its unit is kg meter per second squared times meter. That is equivalent to
. This is also a type of energy.
So, the unit
is the unit of energy.
Answer:
K and N
Explanation:
Ionic character depends on the electronegativity difference between the bonding elements. The greatest the elctronegativity diffference the greatest the ionic character. The electronegativity difference between K and N is the greatest among the four options as N is one of the most electronegative elements.
