Answer:
Sella Turcica
Explanation:
The sella turcica (also called the hypophyseal fossa or pituitary fossa) is a mid-line saddle-shaped depression in the sphenoid bone and belongs to the middle cranial fossa and it can be located by centering the CR (central ray) at a point 3/4" anterior and 3/4" superior to the E.A.M. (external auditory meatus).
Answer:
Explanation:
True
How well a material conducts current is an internal factor affecting resistance.A shorter wire will allow electricity to move through at a higher rate than a longer wire.When a light is first switched on, the light bulb's filament has a lower resistance than after it gives off light for awhile.Superconductors have no measurable resistance.If you double the thickness of a wire, you cut the resistance in half.A short, thick, cold wire is the best conductor.
False
Thickness, length, and temperature are internal factors that affect resistance.The resistance in a wire with less thickness is less.The higher the temperature of the conductor, the lower the resistance.If you double the length of a wire, you cut the resistance in half.
Answer:
Explanation:
Given
zero vertical displacement
suppose \theta is the inclination angle and u is the initial velocity
considering horizontal motion
range is given by
where t is the time of flight
Now consider vertical motion
a=acceleration
for zero displacement y=0
substitute the value of t in Range
for maximum vale of must be equal to 1
i.e.
The addition of antifreeze to
water in a car radiator causes the freezing point of the mixture to increase. The
answer is letter A. It protects the car radiator from freezing due to cold
temperatures. It is added below the freezing point of water to prevent it from
solidifying.
The given question is incomplete. The complete question is as follows.
The block has a weight of 75 lb and rests on the floor for which = 0.4. The motor draws in the cable at a constant rate of 6 ft/sft/s. Neglect the mass of the cable and pulleys.
Determine the output of the motor at the instant .
Explanation:
We will consider that equilibrium condition in vertical direction is as follows.
N - W = 0
N = W
or, N = 75 lb
Again, equilibrium condition in the vertical direction is as follows.
= 0
=
= 30 lb
Now, the equilibrium equation in the horizontal direction is as follows.
or, T =
=
=
= 17.32 lb
Now, we will calculate the output power of the motor as follows.
P = Tv
=
=
= 0.189 hp
or, = 0.2 hp
Thus, we can conclude that output of the given motor is 0.2 hp.
