Speed= (frequency) x (wavelength)
= (2 per second) x (5 cm) = <em><u>10 cm/sec .</u></em>
When the forces acting on a body are balanced, their effect
\on the body's motion is the same as if no forces at all are
acting on it, and its velocity can't change. It continues moving
in a straight line at constant speed (which may be zero).
28J because mechanical energy is the sum of the potential energy and kinetic energy
Answer:
Same, the electric fields point in opposite directions and therefore cancel at some midpoint.
Explanation:
The Electric field net at some point between them is zero, only if they point in opposite direction (they cancel to the each other). In order the electric fields have opposite direction, at some point between the bees , the bees must have the same sign of electric charge
This
B: False, because the definition
is lacking.
Force
is when two objects interact with one another causing it to either move or not
move. In our daily lives there are a lot of times force is exerted upon us,
rather force is everywhere and here are the evidences:
*Pushing
a cart
*Pushing
a wall
*Hitting
a baseball bat
*Apple
falling down from a tree.
*Balls
hitting one another
*A
swinging pendulum
*Throwing
a paper with stone above it
*Breaking
of glass in the floor
*Falling
of leaves on the grass
