Analyze the collision of a baseball with a bat. During which portion of the collision does the baseball’s velocity reach zero?1) before the collision2) during the collision3) one second after the collision4) one-hundredth of a second after the collision

Answers

Answer 1

ANSWER:

2) during the collision

STEP-BY-STEP EXPLANATION:

We have that when a baseball ball collides with a bat, its velocity changes from positive to negative, that is, the ball when hit with an opposing force changes its direction exactly opposite to the initial one.

Therefore, during the collision, at some point in time, the velocity of the ball reaches zero and then finally changes its direction associated with an increase in the velocity of the ball.

jerome pitches a baseball of mass 0.300 kg. the ball arrives at home plate with a speed of 40.0 m/s and is batted straight back to jerome with a return speed of 52.0 m/s. what is the magnitude of change in the ball's momentum?

Answers

The change in the momentum of the ball is 3.6 Kgm/s.

What is momentum?

The term momentum has to do with the product in the velocity of a body and mass of the body. We have to recall at this point that rate of change of momentum is directly related  to the impressed force and this is in accordance with the Newton second law of motion.

Now we have to look at the few pieces of information that we can be able to glean from  the question;

Mass of the object = 0.300 kg

Initial speed of the object = 40.0 m/s

Final speed of the object = 52.0 m/s

Given that the change in the velocity of the object is given by;

m( v - u)

m = Mass of the object

v = Final speed of the object

u = Initial speed of the object

change in the velocity of the object = 0.300(52 - 40)

= 3.6 Kgm/s

The train above is traveling at a constant velocity because the forces acting on it are in equilibrium. Therefore, the missing force must have a magnitude (blank) of newtons to the (blank).

Answers

Answer:

The missing force has a magnitude of 800 N to the right

Explanation:

The forces acting on the train are in equilibrium.

Given:

A voltage source has a voltage of 12 V.

A voltage drop over the LED is 2.5 V.

The current in the circuit is 100 mA.

To find:

The resistance of the resistor should be used.

Explanation:

LED is a forward-biased PN junction that emits light. The voltage drop over the LED is 2.5 V.

The voltage source has a voltage of 12 V.

Hence, the total voltage in the circuit = 12 V - 2.5 V = 9.5 V

The resistance of the circuit in the forward biased is almost equal to zero. Let the resistance in the circuit be R.

The final answer is

(a) The KE = 3.88 * 10

(b) The speed of the arrow is 2.93 * 10

(c) Height which the arrow attains is 4.38 * 10

When the arrow is drawn from a bowstring back then there will be some work done. The pulling of the bowstring will have a distance moved and the energy used to do this.

Given,

Work done = 7 J

Mass of the arrow = 0.09 kg

The computations for a and b are the following:

To calculate the Kinetic energy,

                  Work done = force x distance

                  7.0 J = force x 0.09

                   force = 7/0.09=77.77 = 7.77 x 10

                   force = m. a = 0.09 x a

                    77.77 / 0.09 = a = 864.1 = 8.64*10²

KE = 0.5 x m x v²

     = 0.5 x 0.09 x 864.1

     = 3.88 * 10

The speed of the arrow can be calculated as

       speed 38.8/(0.5 x 0.09) = v² = 862 sq-root

       Hence, v = 2.93*10¹ m/s is the answer

Height that the arrow reaches

       29.3² = 2gh

      = 29.3²/(2 x 9.8) = 858.49 / (2 x 9.8) = 43.8 m

h = 43.8 m or 4.38 * 10¹ is the answer

Therefore, we can conclude that the kinetic energy of the arrow that leaves bowstring is 3.88*10 with the speed of 29.3 m/s and it reaches the height of 43.8 m.

(b) The pressure for first section is p1 = 2.93 x 10^5 Pa

The pressure for the second section will be p2.

The pressure for the second section can be calculated by the formula,

[tex]\begin{gathered} p2=p1+\frac{1}{2}\rho\mleft\lbrace(v1)^2-(v2\mright)^2\} \\ =2.93\times10^5+\frac{1}{2}\times3.43\mleft\lbrace(339)^2-(176.82)^2\mright\rbrace \\ =4.36\text{ }\times10^5\text{ Pa} \end{gathered}[/tex]

Thermal equilibrium implies that:A:the state of restB:absolute zero temperatureC:the maximum temperatureD:equilibrium temperature

Answers

Explanation

Heat is the flow of energy from a high temperature to a low temperature. When these temperatures balance out, heat stops flowing

so, after some time both regions reach thermal equilibrium and no more energy is transfered.so we can conclude that

thermal equilibrium inplies that there is equilibrium temperature

D.equilibrium temperature

I hope this helps you

False The following evidence was gathered to support the idea that polytheistic gods can take a variety of forms.1.) Moreover, because of its dominance of the world, the sun is often seen as all-knowing, and thus sky gods of various cultures tend to be highly powerful and knowledgeable, if also sometimes rather remote.2.) In brief, various cultures have taken existing species in their environment and woven them into the pantheon partly because of their essential dependence on the animals and partly for other reasons, such as similarities between animal forms and other sacred forces (e.g., the analogy of the lion to the force behind kingship).3.) Because human beings can enter into a living relationship with the supernatural beings that surround and dominate their lives, it has always been natural to model the gods as human beings.----------------------------------------------------------------------------------------------------------------------------What additional piece of evidence helps create the MOST COMPLETE idea that polytheistic gods can take a variety of forms.A. In the course of analyzing and recording various beliefs connected with the gods, historians of religions have used certain categories to identify different attitudes toward the gods.B.Though a single evolutionary process cannot be postulated, there has been a drift in various traditions toward the unification of sacred forces under a single head, which, in a number of nonliterate "primal" societies, has become embedded in a supreme being.C.In a number of societies there have been gods of war, such as Mars (ancient Rome) and Skanda (India); gods of learning, such as Sarasvati (India); and gods of love, such as Aphrodite (Greece) and Kama (India).D.The various gods must be seen against the background of a whole host of spirits, demons and other supernatural forces prevalent in the environment of pastoral and agricultural communities. can anyone help me? solve using system of linear equations using elimination x y - 3z = 4 2x + 3y 3z = -2 x + 3y 2z = -4 What is precedence and how is it used in the courts?
