Answer:

W and Z

Explanation:

Work done is the force applied to move a body through a distance in a specific direction.

 Work done  = Force x distance

Now let's use this formula to solve for work done;

Scenario W: A force of 75 N moves a box 15 m.

      Work done  = 75 x 15  = 1125J

Scenario X: A force of 100 N moves a box 12 m.

       Work done  = 100 x 12   = 1200J

Scenario Y: A force of 50 N moves a box 20 m.

      Work done  = 50 x 20  = 1000J

Scenario Z: A force of 25 N moves a box 45 m.

      Work done  = 25  x 45  = 1125J

Choices W and Z is the right option in which the same amount of work is done on the box.

Sonia's grandfather was not able to see clearly after returning from his walk on a bright sunny day. He was about to hit a chair
Vinil7 [7]

Answer:

Sonia's grandfather was not able to see clearly after returning from his walk on a bright sunny day. He was about to hit a chair when Sonia held him and guided him to the nearby sofa, in sunny environment grandfather's eye is set according to high brightness, his pupils become small to lower the number of light rays entering his eye, when he returned from sunny environment to his house which was having low brightness so the pupils should enlarge to absorb more light to see clearly but due to old age his Ciliary muscle of the eye would have worn out and due to this poor coordination the image was not clear.

Through which type of media do mechanical waves, such as sound, move the fastest?
monitta

 Mechanical waves travel the fastest in solids and liquids because the molecules are more closely packed together than gases, so energy is transferred from one particle to another particle faster<span>.</span>

A toy rocket is launched with an initial velocity of 12.0 m/s in the horizontal direction from the roof of a 30.0-m-tall buildin
OlgaM077 [116]

Solution :

The motion in the y direction.

The time taken by the toy rocket to hit the ground,

$S=ut+\frac{1}{2}at^2$

S = distance travelled = 30 m

u = 0 m/s

a = $9.8 \ m/sec^2$

t= time in seconds

Therefore, $30 =\frac{1}{2}9.8 t^2$

t = 2.47 sec

Now motion in the x direction,

u = 12 m/sec

$a=1.6 t \ m/sec^3$

Upon integration 'v' with respect to 't'

$v=\frac{1.6t^2}{2}+12$

Once again integrating with respect to t,

$s=\frac{1.6t^3}{6}+12 t$

$s=\frac{1.6(2.47)^3}{6}+12 (2.47)$

  = 0.0176+29.64

   = 29.65 m

Therefore, the toy rocket will hit the ground at 29.65 m from the building.
