Explanation:

“The Sound of Thunder” is set in the year 2055. Time Safari, Inc. offers time-travel opportunities to hunt and kill exotic and now-extinct animals. In the hunt described in the story, the team of two guides and three hunters goes back to prehistoric days in order to kill the largest dinosaur of them all, a Tyrannosaurus rex. The business has already put safety precautions into place so that these trips can be made without unduly impacting the future. The animals that are killed are ones that have already been identified as doomed. For example, the T rex in question was going to be killed by a falling tree anyway. The safari leaders also built a path for visitors to step on so that no element of the past setting is tampered with. Even the slightest misstep could have implications for the future.

Answer:

10 m/s²

Explanation:

Force is the product of mass of an object and its acceleration

The formula is : F= m*a  -----where m is mass and a is acceleration

Use the values given in the equation as;

F= m*a

1000 = 100 * a

1000/100 = a

10 = a

10 m/s² = a

Answer:

1.5 m/s^2

Explanation:

a = velocity/time

27/18 = 1.5 m/s^2

Answer:

s = t⁴/108+6t+24

v = t³/27 + 6

Explanation:

Given the equation of acceleration expressed as a = kt²

t is in seconds

To get the velocity, we will integrate the acceleration function

a = kt²

Integrate both sides

a = kt²

v = ∫kt² dt

v = k ∫t² dt

v = kt³/3 + C1..... *

s = ∫kt³/3 dt+ ∫C1 dt

s = kt⁴/12+C1t + C2

At t = 0, S= 24

24 = k(0)⁴/12 + C1(0)+ C2

24 = C2

s = kt⁴/12+C1t + 24

If at t = 6 seconds, s = 96m

Substitute;

96 = k6⁴/12+6C1+ 24 .... **

Also at t = 6, v = 18m/s

Substitute into *

v = kt³/3 + C1..

18 = k6³/3 + C1..... ***

Solve ** and *** simultaneously and get k and C1

96 = k6⁴/12+6C1+ 24

k6⁴/12+6C1+ = 72 × 1

k6³/3 + C1 = 18 × 6

---------------------------

k6⁴/12+6C1+ = 72

k6⁴/3 + 6C1 = 108

Subtract

[(6⁴k)-4(6⁴k)]/12 = 72-108

-3(6⁴k)/12 = -36

6⁴k/12 = 12

6⁴k = 144

k = 144/1296

k = 1/9

Substitute k = 1/6 into k6³/3 + C1 = 18 and get C1

1/6(216/3) + C1 = 18

12+ C1= 18

C1 = 18-12

C1 = 6

Write s in terms of t;

s = kt⁴/12+C1t + 24

s = 1/9t⁴/12+6t+24

s = t⁴/108 + 6t + 24

Write v in terms of t;

v = kt³/3 + C1

v = 1/9(t³/3)+6

v = t³/27 + 6

Given parameters:

Speed of the dog  = 3.8m/s

Kinetic energy  = 231.04J

Unknown:

Mass of Mr.Plamer's dog = ?

Solution:

Kinetic energy is the energy due to the motion of a body;

Mathematically, it is represented as;

      K.E  = [tex]\frac{1}{2}[/tex] m v²

  m is the mass

  v is the velocity

Insert the parameters and solve;

        231.04  = [tex]\frac{1}{2}[/tex]  x m x 3.8²

        231.04 x 2  = 2 x  [tex]\frac{1}{2}[/tex]  x m x 3.8²

           462.08  = 14.44m

               m  = 32kg

Answer:

268N

Explanation:

The upward force acting on the block are the reaction and the hooked table..

The total normal force acting = normal reaction + 24N

Note that the normal reaction is always equal the weight of the table

Hence the normal force acting in the block is 244.0+24 = 268.0N

Answer:

hello your question lacks some data and required diagram

G = 77 GPa,  т all = 80 MPa

answer : required diameter = 252.65 * 10-^3 m

Explanation:

Given data :

force ( P )  = 660 -N force

displacement = 15 mm

G = 77 GPa

т all = 80 MPa

i) Determine the required diameter of shaft BC

considering the vertical displacement ( looking at handle DC from free body diagram )

D' = 0.3 sin∅  ,   where D = 0.015

hence ∅ = 2.8659°

calculate the torque acting at angle ∅  of  CD on the shaft BC

Torque = 660 * 0.3 cos∅

             = 660 * 0.3 * cos 2.8659 = 198 * -0.9622 = 190.5156 N

hello attached is the remaining part of the solution

The required diameter of shaft BC will be 252.65 ×10⁻³A shaft's diameter is the line that goes through its center and splits it into two equal halves.

A diameter is a line that travels through the center of a sphere and intersects the circumference at opposing ends. It measures twice as long as the sphere's radius

The given data in the problem is;

P is the force = 660 N

d is the displacement = 15 mm

G is the constant= 77 GPa

τ is the shear stress= 80 MPa

From the torsional equation;

[tex]\frac{\tau}{R} =\frac{T}{j} \\\\ \frac{\pi}{32} \times d^4=\\\\ \tau =\frac{T \times R}{J} \\\\\ \tau =\frac{T \times (\frac{d}{2} )}{J} \\\\ 80= \frac{32 \times 190 \times \frac{d}{2} }{\pi} \\\\\\d=252.65 \times 10^{-3}[/tex]

Hence the required diameter of shaft BC will be 252.65 ×10⁻³.

b. A steel paper clip near a magnet

Explanation:

A steel paper clip near a magnet is an object that most likely has magnetic domains because of its inner composition.

A magnetic domain is a part or region within a magnetic substance in which the magnetization is present in a uniform direction.

So we can conclude that a steel paper clip near a magnet is an object that most likely has magnetic domains because of its inner composition.

Answer:

9m/s²

Explanation:

Given parameters:

Initial velocity  = 30m/s

Final velocity  = 0m/s

Distance traveled  = 50m

Unknown:

Deceleration  = ?

Solution:

To solve this problem, we apply the proper motion equation;

          V²   = U²   +  2aS

V is the final velocity

U is the initial velocity

a is the acceleration

S is the distance

  Insert the parameters and solve;

          0²  = 30²  + 2(a)50

          -900  = 100a  

              a = -9m/s²

The negative value indicates deceleration.

The motorcycle decelerates at a rate of 9m/s²

Answer:

[tex]\boxed {\boxed {\sf 80 \ Newtons}}[/tex]

Explanation:

Force can be found by multiplying the mass by the acceleration.

[tex]F=m*a[/tex]

The mass of the pumpkin is 40 kilograms.

The acceleration of the pumpkin is 2 meters per second squared.

[tex]m= 40 \ kg \\a= 2 \ m/s^2[/tex]

Substitute the values into the formula.

[tex]F= 40 \ kg *2 \ m/s^2[/tex]

Multiply.

[tex]F= 80 \ kg*m/s^2[/tex]

A kilogram meter per second squared is equal to 1 Newton. Therefore, our answer of 80 kg*m/s² is also equal to 80 Newtons (N).

[tex]F=80 \ N[/tex]

The force is 80 Newtons.

This question is incomplete

Explanation:

This question is incomplete because of the absence of options. However, Astronauts working in space do not have any external force acting upward or downward on them; meaning there is no contact force pushing or pulling there body and thus experience/feel weightlessness. This causes them to be in a state of constant free fall when they are orbiting the earth. This free fall is similar to what is experienced in elevators and roller coasters in amusement parks.

Now the best way to communicate and show her new discovery and results on gravity with the other scientist is to publish her findings in a famous science journal so that other scientist can work on it and make some test to find the same results.

By doing this, other scientist can work on her idea and she can tell and communicate her discovery with the other scientist and physicists.  

Answer:

Increase gas pressure and decrease gas temperature

Explanation:

To Create a lab simulation whereby the changes in pressure exerted on the gas will affect the volume of the gas volume negatively ( decrease in gas volume ) the changes that Juana should program is to increase the pressure on the gas molecules because increase in gas pressure  = decrease in gas volume while increase in temperature will lead to increase in gas

Hence in order to effectively achieve the decrease in gas volume with the lab simulation; she should increase gas pressure and decrease gas temperature

Answer:

Answer:

his is an example of the transformation of gravitational potential energy into kinetic energy

Explanation:

The game of juggling bowling is a clear example of the conservation of mechanical energy,

when the bolus is in the upper part of the path mechanical energy is potential energy; As this energy descends, it becomes kinetic energy where the lowest part of the trajectory, just before touching the hand, is totally kinetic.

At the moment of touching the hand, a relationship is applied that reverses the value of the speed, that is, now it is ascending and the cycle repeats.

Therefore this is an example of the transformation of gravitational potential energy into kinetic energy
