marissas car accelerates uniformly at a rate of -2.60m/s^2. how long does it take for marissas car to accelerate from a velocity of -28.2m/s to -42.3m/s?
Answer:
1.02s
Explanation:
In this situation the following equation will be useful:

Where:
 is Marissa's car final velocity
 is Marissa's car initial velocity
 is Marissa's car constant acceleration (assuming this is the acceleration, since 1269 m/s^{2} does not make sense)
 is the time it takes to accelerato from  to 
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.

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

OPTIONS:
A.
It will be very easy to get sick.
B.
It will result in a lack of energy.
C.
It will negatively impact coordination.
D.
It will cause the body to create too much sugar.
PLEASE NO LINKS
Answer: It is b
Explanation:
The lack of protein in the body will result in a lack of energy in the body. Hence, option B is correct.
What is protein?Proteins are created from a variety of amino acid building blocks. Our body needs dietary protein to supply amino acids for the growth and upkeep of our cells and tissues. As we become older, our dietary needs for protein change.
Proteins are made up of many different amino acids that are joined together. Both plants and animals have a lot of these 20 different amino acid building blocks. Each protein has a unique ratio and arrangement of the 300 or more amino acids that make up a typical protein.
Our body is made up of thousands of different proteins, each of which has a specific function. They contribute to the structural components of our cells and tissues, along with the countless enzymes, hormones, and active proteins produced by immune cells.

A current of 0.2 A flows through a conductor for 5minutes. How much charge would have passed through the conductor?
As we know,
[tex]electric \: \: current = \dfrac{charge}{time} [/tex]
so, let's solve for charge (q) :
time = 5 minutes = 5 × 60 seconds = 300 seconds.
[tex]0.2 = \dfrac{q}{300} [/tex][tex]q = 300 \times 0.2[/tex][tex]q = 60[/tex]hence, the charge = 60 coulombs (C)

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.
