Answer:

18.425 Joules

Explanation:

To figure this out we can simply use the W=Change in Kinetic Energy,

W = 1/2*.022*46^2-1/2*.022*21^2 (Note we can ignore the direction of the particles as we need to take the square of the velocity)

W=18.425 (By simplifying the expression)

The kinetic energy of the bowling ball is 56 J

Kinetic energy is the energy possessed by an object is motion.

From the question given above, the following data were obtained:

KE = ½mv²

KE = ½ × 7 × 4²

KE = 3.5 × 16

KE = 56 J

The kinetic energy and gravitational potential energy changes during its movement from ground to the top height.

When the ball moves upward, its gravitational potential energy is increases and kinetic energy begins to decrease but when the ball falls towards the earth, its gravitational potential energy is transformed into kinetic energy. When the ball collides with the ground, the kinetic energy is transformed into other forms of energy.

Explanation: There are only three muscle types in the exercise physiology.

Skeletal Muscle

Smooth Muscle

Cardiac Muscle

Answer:

True

Explanation:

The statement "elastic energy is a type of kinetic energy" is absolutely false.

Kinetic energy may be defined as a type of energy that is typically possessed by an object due to its motion. It is characterized as the work which is required in order to accelerate a body of a given mass from rest to its initiate velocity.

Elastic energy is a type of mechanical potential energy that is kept in reserve in the arrangement of a material or physical system as it is conquered by elastic deformations.

Elastic energy is a type of energy that is occurred when any objects are temporarily compressed, stretched, or typically disfigure in any manner.

Therefore, the statement "elastic energy is a type of kinetic energy" is absolutely false.

The horizontal speed of a pumpkin, [tex]v_x=4\ m/s[/tex]

The horizontal distance covered by the pumpkin, [tex]d_x=9.5\ m[/tex]

We can assume to find the the pumpkin's vertical displacement during the throw.

Firstly we can find the time of flight for the pumpkin. It can be calculated as follows :

[tex]t=\dfrac{d_x}{v_x}\\\\t=\dfrac{9.5}{4}\\\\t=2.37\ s[/tex]

The vertical displacement during the throw is given by :

[tex]y=u_yt+\dfrac{1}{2}a_yt^2[/tex]

Here, [tex]u_y=0\ \text{and}\ a_y=-g[/tex]

So,

[tex]y=\dfrac{1}{2}gt^2\\\\y=\dfrac{1}{2}\times 9.8\times (2.37)^2\\\\y=27.522\ m[/tex]

So, the vertical displacement of the pumpkin is 27.522 m.

The net force would be needed to accelerate a 2.95kg bowling ball at 6.25m/s^2 will be F = 18.4375 N

Newton's second law of motion  states that the time rate of change of the momentum of  a body is equal in both magnitude and direction to the force  imposed on it.

For a constant mass , force is equal to  Force = mass * acceleration

given

mass(M) = 2.95 kg

acceleration(a) = 6.25 m/s^2

Force(F)  = ?

Force(F) = mass(M) * acceleration(a)  (from Newton's second law of motion  )

F =  2.95 * 6.25

F = 18.4375 N

The net force would be needed to accelerate a 2.95kg bowling ball at 6.25m/s^2 will be F = 18.4375 N

Traditional Method->>>>I'm not 100% sure of my answer but gl buddy

Step 1 Identify the Null Hypothesis and the Alternative Hypothesis

Step 2 Identify α (Level of Significance)

Step 3 Find the critical value(s)

Step 4 Find the test statistic

 For a Proportion: Hand calculation

TI 83/84 – Use 1PropZTest (See Handout H-404)

 For a population mean (with α known):

TI 83/84 - Use Z-Test (See Handout H 404)

 For a population mean (with α Not known):

TI 83/84 - Use T-Test (See Handout H-404)

Step 5 Draw a graph and label the test statistic and critical value(s)

Step 6 Make a decision to reject or fail to reject the null hypothesis

 Reject - The test statistic falls within the critical region.

 Fail to Reject - Test statistic does not fall within the critical

region.

P-Value Method:

P-value is the area determined as follows:

 Left Tail Test: p-value is the area to the left of the test statistic.

 Right Tail Test: p-value is the area to the right of the test statistic.

 Two Tailed Test: p-value is twice the area bounded by the test statistic

Make a decision to reject or fail to reject the null hypothesis:

 Reject if p-value ≤ α

 Fail to reject if p-value > α

Two lethal elements can combine to form an essential compound for health by undergoing a chemical reaction such that the properties of the individual elements are different from the properties of the product and are no more lethal

Example Mercury and Sulfur combine to form cinnabar which is used as a medicine to relieve pain, antiseptic, and to cure diseases

Mercury and sulfur combines because mercury readily combines with sulfur at high temperatures

Answer:

The weight of heart of a human is 0.93 lbs.

Explanation:

Given that,

Approximately weight of heart is 0.5 % of the total body weight.

Weight of human = 185 lbs

Let the the weight of total body is w and weight of heart is [tex]w_{h}[/tex].

We need to calculate the weight of heart of a human

Using given data

[tex]w_{h}=0.5\times w[/tex]

Where, h = weight of heart

w = weight of human

[tex]w_{h}=\dfrac{0.5}{100}\times 185[/tex]

[tex]w_{h}=0.93\ lbs[/tex]

Hence, The weight of heart of a human is 0.93 lbs.

The left hemisphere of the brain controls the right side of the body. So, the given statement is True.

The brain is defined as the most complex part of the human body, a three-pound organ that is the seat of intelligence, the interpreter of the senses, the initiator of body movement, and the controller of behavior. The brain is said to be the source of all the qualities that define our humanity.

The brain is usually divided into symmetrical left and right hemispheres with each hemisphere in charge of the opposite side of the body, so the right brain controls the left hand while the right hemisphere also takes sensory input from the left and vice versa.

    [tex]\sigma  =  2.2125* 10^{-7} \  C/m^2[/tex]

c

 [tex]q = 2.2125 *10^{-8} \  C  [/tex]

d

 [tex]C = 4.425 *10^{-10} \ F[/tex]

e

 [tex]U  = 5.531 *10^{-7} \  J[/tex]

Explanation:

From the question we are told that

   The distance of separation is [tex]d =  2mm =  0.002 \ m[/tex]

   The  voltage is [tex]V  = 50\  V[/tex]

   The area is  [tex]A  =0.1m^2[/tex]

Generally the  electric field is mathematically represented as

      [tex]E =  \frac{V}{d}[/tex]

=>     [tex]E =  \frac{50}{ 0.002}[/tex]

=>     [tex]E =  25000 \  V/m[/tex]

Generally the capacitance  mathematically  represented  is

       [tex]C =  \frac{\epsilon_o  * A  }{d}[/tex]

Here [tex]\episilon_o[/tex] is the permitivity of free space with value  

      [tex]\episilon_o = 8.85 * 10^{-12} C/(V⋅m   [/tex]

=>       [tex]C =  \frac{ 8.85 * 10^{-12}  * 0.1  }{0.002}[/tex]

=>      [tex]C = 4.425 *10^{-10} \ F[/tex]

Generally  the charge  is mathematically represented as

     [tex]q =  C  * V[/tex]

      [tex]q = 4.425 *10^{-10}   *50 [/tex]

=>    [tex]q = 2.2125 *10^{-8} \  C  [/tex]

Generally the charge density is  mathematically represented as

       [tex]\sigma  =  \frac{q}{A}[/tex]

=>   [tex]\sigma  =  \frac{ 2.2125 *10^{-8}}{0.1}[/tex]

=>   [tex]\sigma  =  2.2125* 10^{-7} \  C/m^2[/tex]

Generally the energy stored in this capacitor is mathematically

    [tex]U  = \frac{1}{2} *  CV^2[/tex]

=>  [tex]U  = \frac{1}{2} *  (4.425 *10^{-10} ) * (50)^2[/tex]

=>   [tex]U  = 5.531 *10^{-7} \  J[/tex]
