The term <span>dorsiflexion means to bend the foot upwards at the ankle.
</span><span>Dorsiflexion means to flex the joint of the ankle in such way that the underside of the foot is rotated upwards where the upper surface of one's toes are moved towards the shin bones that are found at the front of the lower leg.</span>
(a) We will use the equation v = u + at
Initial velocity u = 5.00 m/s
Acceleration a = 0.0600 m/s²
time = 8 min = 8 x 60 = 480 s
Final velocity
= u + at
= 5.00 + 0.0600(480)
= 33.8 m/s
The final velocity is 33.8 m/s
This is more along the lines of "Does gravity affext potential energy"
Sort of. Potential energy is an odd one to imagine, sometimes.
It's the energy possessed by an object or system by dint of it's spatial
and mechanical configuration.
That definition alone is perhaps not so useful...and it's certainly not
official. But what it means is that an object can potentially have
energy due to where it is or what state the system is in.
Imagine we have a box and it's on the floor. The box, for all intents
and purposes, has no potential energy. It isn't going anywhere and it
just sits on the floor. It can't do any work in it's current position.
Now we hoist the box into the air. For any distance the box travels from
the floor, it gains potential energy. Now let's back track. We've
changed the box's spatial configuration by hoisting it into the air and
so have given it potential energy.
Why does it now have potential energy? Because we can now drop the box
(costing us no energy) and the box will fall. Maybe it falls onto a
passer-by and injures them.
Box on the floor = No energy.
We lift the box = We spend our energy and give the box potential energy
(as it wants to fall toward the ground).
We drop the box = Potential energy is converted to kinetic energy as the
box falls.
Box injures someone = The kinetic energy has done work upon the person.
So we can see how it all flows and connects. We have to put energy into
the box to fight against gravity, but you can't destroy or create
energy....so the energy we've spent is potentially stored 'inside' the
box.
Clearly, gravity effects a LOT of potential energies around us. In fact
to some small extent, it's probably impossible to entirely avoid it's
effects.
Answer:
Explanation:
The relation between electric field and potential difference is as follows
E = - dV / dr
That means if dV is positive , E is negative . In other words , if potential increases , E is negative or in opposite direction in which potential increases .
Here the electric potential increases uniformly from east to west , that means electric field is from west to east . Since potential is uniformly increasing that means
dV / dr = constant
E = constant
Electric field is constant .
So the option which is correct is
" points east and does not vary with position " .
<span>So we want to know is it true or false that geothermal energy is derived from the Sun. Geothermal energy is heat energy that is stored in the Earth. Solar energy is energy that we get by collecting sunlight via solar collectors and turning it into electrical energy. So the answer is FALSE. </span>
