Answer:
E = 8.26*10⁻¹⁰ N/C, due south.
Explanation:
- Assuming no other forces acting on the electron than the electrostatic force due to the electric field, we can apply Newton's 2nd law as follows:
- Solving for E, we can find its magnitude as follows:
- The direction of the electric field is by definition the one that would take a positive test charge, so if the electron is accelerated to the north, the electric field would exactly oppose to this direction, so it is directed due south.
Answer:
The reason that it takes longer to get the water to boiling temperature than it is to cool it down again is because heating in the most simple sense is inefficient and will cause a lot if energy lost while cooling is to be turn's into quite a efficient process.
Explanation:
we know that,
Frequency = 1/ time period
hence, Feq = 1/5 ===> 0.2 Hz
hence, wave velocity = freq * wavelength
hence,
V = 0.2 * 100
==> Wave velocity = 20 m/s
Answer:
third
Explanation:
for every action there is an equal and opposite reaction
example
bouncing ball
ball receives a force from the ground due to collision
that same force causes the ball to bounce off the ground
first law:
inertia
example
stuff in space doesn't move unless its pushed
then it keeps going unless something stops it
second law
force = mass times acceleration
example
harder you push a cart the faster it goes
the less a cart weighs the faster a cart goes
