Answers
Answer:
Your answer will be D.
The ball is traveling at a steady speed until it hits an unbalanced force and changes direction.
Explanation:
The ball is traveling at a steady speed until it hits an unbalanced force and changes direction. The correct option is D.
Thus, An unbalanced external force acts upon an item, Newton's first law of motion, often known as the law of inertia, asserts that an object at rest will remain at rest and an object in motion will continue to move in the same direction and at the same pace.
When a baseball is struck with a bat, it is originally at rest or moving steadily forward.
The ball experiences an imbalanced force when it is struck by the bat, altering its direction and speed. The bat's application of external force is what causes this shift in motion.
Thus, The ball is traveling at a steady speed until it hits an unbalanced force and changes direction. The correct option is D.

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 15 kg chunk of ice falls off the top of an iceberg. If the chunk of ice falls 8m to the surface of the water what is its velocity?
Answers
Answer:
When we can get the Kinetic energy from this formula KE= 1/2 M V^2and we can get the potential energy from this formula PE = M g H
we can set that the kinetic energy at the bottom of the fall equals the potential energy at the top so, KE = PE
1/2 MV^2 = M g H
1/2 V^2 = g H
when V is the velocity, g is an acceleration of gravitational force (9.8 m^2/s) and H is the height of the fall (8 m).
∴ v^2 = 2 * 9.8 * 8 = 156.8
∴ v= √156.8 = 12.5 m/s

El cuerpo de 2kg se suelta de A recorriendo el plano inclinado 60° con la horizontal y de superficie lisa hasta el punto B. Luego recorre el tramo rugoso BC deteniéndose en C. Hallar “L” si se sabe que μ= 0,6.
Answers
El valor de L del tramo rugoso B a C con coeficiente de fricción igual a 0,6, recorrido por el cuerpo de 2 kg cuando se suelta del punto A es 5.00 m.
El valor de L se puede calcular a partir de la definición de trabajo:
[tex]W = F_{\mu}*d[/tex] (1)
En donde:
[tex]F_{\mu}[/tex]: es la fuerza aplicada sobre el cuerpo en el tramo de B a C = fuerza de roce = -μN (el signo menos se debe a que está en dirección opuesta a la del movimiento)
μ: es el coeficiente de roce = 0,6
N: es la normal = mg
m: es la masa del cuerpo = 2 kg
g: es la aceleración debida a la gravedad = 9,81 m/s²
d: es la distancia = L =?
Por otra parte, el trabajo también se define como la diferencia de energía mecánica entre los puntos B y C.
[tex] W = E_{C} - E_{B} [/tex] (2)
Al igualar la ecuación (1) con la (2) tenemos:
[tex]E_{C} - E_{B} = F_{\mu}*d[/tex] (3)
En el punto C, la energía es cero (0) dado que el cuerpo se detiene y en el punto B la energía que tiene el objeto es la cinética:
[tex] E_{B} = \frac{1}{2}mv_{B}^{2} [/tex]
En donde:
[tex]v_{B}[/tex]: es la velocidad del cuerpo en el punto B
La velocidad del cuerpo en el punto B se puede calcular mediante conservación de energía entre los puntos A y B:
[tex] E_{A} = E_{B} [/tex]
En el punto A, el cuerpo tiene energía potencial gravitacional, por lo tanto:
[tex] mgh = \frac{1}{2}mv_{B}^{2} [/tex] (4)
En donde:
h: es la altura = 3 m
Entonces, la velocidad en el punto B es (eq 4):
[tex] v_{B} = \sqrt{\frac{2mgh}{m}} = \sqrt{2*9,81 m/s^{2}*3 m} = 7,67 m/s [/tex]
Ahora, la ecuación (3) queda como sigue:
[tex] 0 - \frac{1}{2}mv_{B}^{2} = -\mu N*L [/tex]
[tex] \frac{1}{2}2 kg*(7.67 m/s)^{2} = 0,6*2 kg*9,81 m/s^{2}*L [/tex]
Resolviendo para L, tenemos:
[tex] L = \frac{\frac{1}{2}2 kg*(7.67 m/s)^{2}}{0,6*2 kg*9,81 m/s^{2}} = 5.00 m [/tex]
Por lo tanto, el valor de L es 5.00 m.

Sound waves travel at a speed of 330.0 m/s . How long does it take for the sound of thunder to travel 1.5 km ? (20points)
Answers
4.55 seconds
Step-by-step explanation:-Given, Speed = 330.0 m/s
To find the time, it will take for the sound of thunder to travel 1.5 km, we have to apply the formula for speed :
[tex]speed = \frac{distance}{time} [/tex]
This implies that:-
[tex]time = \frac{distance}{speed} [/tex]
So, Let's get started with the steps -
Step 1- Convert 1.5 km to metres.
[tex]1.5 \: km \: \\ = > \: 1.5 \times 1000 \\ = > 1500 \: m[/tex]
Step 2- Now, to get time, substitute the values you got now in "time=distance/speed"
[tex]t = \frac{1500}{330}[/tex]
[tex] => t = 4.55 \: seconds[/tex]
Therefore, the answer is 4.55 seconds

The resultant of the four forces on the balloon is 1,212.35 N at 62⁰.
The given parameters;
Force applied to the north = 5120 NForce applied to the west = 1520 NForce applied to the east = 950 NForce applied to the south = 4050 NThe resultant vertical force is calculated as follows;
[tex]F_y = 5120 \ N - 4050 \ N\\\\F_y = 1,070 \ N[/tex]
The resultant horizontal force is calculated as follows;
[tex]F_x = 1520 \ N - \ 950 \ N\\\\F_x = 570 \ N[/tex]
The resultant of the four forces is calculated as follows;
[tex]F = \sqrt{F_y^2 + F_x^2} \\\\F = \sqrt{(1,070)^2 + (570)^2} \\\\F = 1,212.35 \ N[/tex]
The direction of the force is calculated as follows;
[tex]\theta = tan^{-1} (\frac{1070}{570} )\\\\\theta = 62^0[/tex]

A projectile is launched with an initial speed of 12 m/s. At its highest point its speed is 6 m/s. What was the launch angle of the projectile?
Answers
We want to find at what angle a projectile is launched given that at the highest point, the speed is 6m/s.
The launch angle of the projectile is 60°.
Remember that the only acceleration will appear on the vertical axis, and this is the gravitational acceleration, this means that on the horizontal axis we will have a constant speed.
Also remember that when an object is on its highest point, the vertical velocity is equal to zero, then it only has horizontal velocity (which we know it is a constant).
Then we can conclude that the horizontal velocity is equal to 6m/s.
If the angle is measured from the horizontal axis, we will have that the horizontal velocity is a projection on the x-axis of the initial speed, this is:
12m/s*cos(θ) = 6m/s
Now we can solve this for theta.
cos(θ) = (6m/s)/(12 m/s) = 1/2
θ = Acos(1/2) = 60°
The launch angle of the projectile is 60°.
