What is an example of a partially movable joint?

1 answer:

3 0

<span>A partially movable joint is a joint in which its movement is limited to a certain amount. They are usually supported by a layer of cartilages and fibrous connective tissues. They are also called amphiarthrosis joints. Example of this are the joints formed by adjacent vertebrae containing intervertebral disc of a cartilage. When the joints are moved, it limits its movement because of this arrangement. Other examples of this are the ribs and the sternum. Notice that you cannot twist your upper body at 360 degrees without moving your lower body.</span>

Refer to the drawing that accompanies Check Your Understanding Question 14. Suppose that the voltage of the battery in the circu

Gnoma [55]

Answer:

Maximum speed of the rod, v = 10.34 m/s

Explanation:

It is given that,

Voltage of the battery, V = 2.7 V

The magnetic field perpendicularly into the plane of the paper is, B = 0.9 T

Length of the rod between the rails, l = 0.29 m

Due to the motion of the rails inside the magnetic field, an emf will induced in it which is given by :

$\epsilon=Blv$

v is the speed attained by the rod

$v=\dfrac{\epsilon}{Bl}$

$v=\dfrac{V}{Bl}$

$v=\dfrac{2.7}{0.9\times 0.29}$

v = 10.34 m/s

So, the maximum speed attained by the rod after the switch is closed is 10.34 m/s. Hence, this is the required solution.

in as small room fan of rating 50 watt is used for 10hrs 2bulb of rating 10v are used for 8hrs daily.calculate monthly. electric

Pie

Answer:

The electric bill for June is Rs198000

Explanation:

Convert volt to watt, but in order to do so I need to know the amps and since it is not provided I converted if the amps was 1.

I multiple 50 with 10 then with 30 so I know how much watt the fan takes at June.

Since there are 2 light bulb I multiple 10 with 2 than with 8 than with 30.

15000 watts for the fan,

4800 watts for light bulb,

add them and then times it by 10.

Rs198000

The tires on your truck have 0.35 m radius. In a straight line, you drive 2600 m. What is the angular displacement of the tire,

Travka [436]

1) In a circular motion, the angular displacement $\theta$ is given by
$\theta = \frac{S}{r}$
where S is the arc length and r is the radius. The problem says that the truck drove for 2600 m, so this corresponds to the total arc length covered by the tire: $S=2600 m$ . Using the information about the radius, $r=0.35 m$ , we find the total angular displacement:
$\theta = \frac{2600 m}{0.35 m} =7428 rad$

2) If we put larger tires, with radius $r=0.60 m$ , the angular displacement will be smaller. We can see this by using the same formula. In fact, this time we have:
$\theta = \frac{2600 m}{0.60 m}=4333 rad$
