Your thumb contains the only saddle joint in the entire body. How would your hand function differently if your thumb contained a pivot joint? What if it contained a ball and socket joint? Describe four consequences of having a different type of joint in the thumb.

P.S. Detailed Response plz

Answers

Answer 1

Answer:

The saddle joint allows movement in different directions but only a small amount of rotation. The thumb is the only organ that has a saddle joint.

It should be noted that the bones that are in the saddle joint ensure the back and forth movement of the thumbs.

The pivot joint is the joint that's responsible for ensuring that one bone rotates around another bone. Ball and socket joint can be found in the shoulder and the hip and it allows for greater freedom of movement.

When compared to other movable joints, the saddle joint is prone to dislocation because it's free-moving and rotates on its own axis alone.

In conclusion, if the thumb contained a pivot joint or a ball and socket joint, it'll be able to move more freely.

will an object have the same weight on moon as it does ?

Answers

Answer:

The mass of an object is the same everywhere either on earth or moon.

The weight of an object depends on a gravitational acceleration and it's different from one on earth and that on moon.

therefore the weight changes but the mass is the same.

Answers

Friction is one of the forces working against a moving object, it makes it harder to move the more friction is exerted on the object. So, by reducing friction, you are making it easier for you to be able to move objects.

In a trial, an expert witness uses the conservation of momentum to demonstrate which initial velocities would give the final states that occurred in the accident. Can using the conservation of momentum be justified in this case? Yes, because momentum is conserved in all collisions. No, momentum is only conserved in elastic collisions which this is not. No, energy is always conserved, but momentum is only sometimes conserved. Yes, because momentum is conserved in inelastic collisions which all car accidents are.​

This equation tells the position of the ball, x, at any time t. Let's use it to solve for the position of the ball at t=0.00231 s. What value do you get when you use t=0.00231 s and solve for the position, x?

Answers

The slope of the graph, A, and the starting position of the ball, B, can be used to determine the position of the ball

The position of the ball at time t = 0.00231 s is 59.933 cm

Reason:

Question; The possible function representing the given equation is presented as follows;

x = A·t + B

Where;

A = 2.59 × 10⁴ [tex]\frac{cm}{s}[/tex]

B = 0.104 cm

t = Time in seconds (s)

x = The position (cm)

Required: The value of the position when t = 0.00231 s

Solution:

The position time graph of an object moving with a constant speed is a straight line with an equation of the form y = m·x + c

Plugging in the value of t = 0.00231 in the given equation gives;

x = 2.59 × 10⁴ × 0.00231 + 0.104 = 59.933

The position x of the ball at time, t = 0.00231 s is 59.933 cm

10 Psychological Tricks That Can Make Your Life Much Easier
1. Look into someone’s eyes when you get a dissatisfactory answer: Sometimes we don’t like the answer to a question that we receive and sometimes we don’t understand it. Instead of repeating the question or asking another, look into the eyes of the person. This will make the person feel under pressure or cornered, and this will force them to further elaborate their thoughts.

2. Stay calm when someone raises their voice to you: Make a strong effort to remain calm. When a loudmouth acts out it’s usually in anger, and our behaviors can sometimes unintentionally provoke that. The feelings of anger usually quickly subside and guilt will set in and usually this person is first to ask for forgiveness.

3. Sit close to the aggressor to avoid attack: If you’re heading into a meeting and you know you’ll be in the room with an aggressive person, you know the discussion may become heated, or you may be subjected to negative criticism, make a point to sit next to that person. You may feel uncomfortable and awkward, but you won’t be the only one. Close proximity is known to make people uncomfortable which will lessen the level of aggression they plan to exercise.

4. Remember everyone’s names if you want to be popular: If you want to be popular with your peers and colleagues, make it a habit to start calling people by their first names when speaking with them. A person feels instantaneously special when you call him or her by their first name.

5. Write down your thoughts when you feel stressed or anxious: We all feel some level of mental stress or anxiety at some point. Write down your thoughts in a journal and then close it up. Believe it or not, you’ll be able to focus on your work more easily because you have now shared your thoughts with someone. When you share them, you will then feel the burden on your mind reduced.

6. Give yourself fewer choices when you can’t make the decision:Some people believe that it’s better to have more choices and more information and actually, they prefer to have more. However, it is actually paralyzing to have too many. There is evidence that shows that having four options at a time is the maximum number we can consider and still make a choice. In order to be an effective decision maker, you should only give yourself a few options at a time. This will allow you time to consider each one while giving you enough space between looking at a new set of options.

7. Right posture can boost confidence: This psychological trick applies to both work and pleasure. It can drastically improve your dating life and help you move up the ladder at work. How can you become confident do you ask? The best way to do this is through your posture. If you allow yourself to take up more space, you’re more likely to feel more confident. This is referred to power language.

8. Surefire way to win in ‘rock, paper, scissors’: This one is definitely intriguing. When you’re about to play this famous game, ask your opponent a random question right before. This typically will throw your confused opponent off and more often than not they will throw up ‘scissors’.
9. Make people feel needed when you ask for help: If you need someone’s help start off with the phrase, ‘I need your help…’ People like to feel needed and they hate feeling guilty. By starting off the conversation with that phrase, you’re more likely to receive the help you need.

10. Warm your hands before shaking hands with others:Did you know that cold hands are linked to distrust? When you’re about to touch someone or shake their hand, make sure that your hands are warm. Warm hands promote a friendly atmosphere.

and those are the ten physiology tricks.

A rubber duck sat is floating on the surface
on the water. 10N of weight is acting
DOWNWARDS on the water. What other
force must be acting to allow the duck to
float?

Answers

The other force that must be acting on the duck is upthrust of 10 N.

The given parameters;

weight of the rubber duck, W = 10 N

When the weight of the object is equal to the upthrust, the apparent weight will be zero and the object will float in the liquid. This is known as principle of floatation.

Since the given weight of the rubber duck is 10 N, then the upthrust on the duck will be 10 N to enable the duck float on the water.

Thus, the other force acting on the duck is upthrust of 10 N.
