Question 1 (1 point)Select all solutions to the equation.
3x – y=10
Only (4,-2)
Only (3, 1)
Both (4, -2) and (3, 1)
Neither

Answer:

Option B is correct.

Step-by-step explanation:

4x+3y-z= -6     eq(1)

6x-y+3z= 12     eq(2)

8x+2y+4z=6    eq(3)

We need to solve these equations and find the value of x, y and z.

Multiply equation 2 with 3 and then add equation 1 and 2

18x -3y +9z = 36

4x +3y -z = -6

_____________

22x + 8z = 30    eq(3)

Multiply equation 2 with 2 and add with equation 3

12x -2y + 6z = 24

8x +2y +4z = 6

____________

20x + 10 z = 30  eq(4)

Multiply equation 3 with 10 and equation 4 with 8 and then subtract

220x + 80z = 300

160x + 80z = 240

-        -            -

_________________

60x = 60

x= 60/60

x= 1

Putting value of x in equation 3

22x + 8z = 30

22(1) + 8z = 30

8z = 30 - 22

8z = 8

z = 8/8

z=1

Putting value of x and z in equation 1

4(1)+3y-(1)=-6

4 + 3y -1 = -6

3 + 3y = -6

3y = -6 -3

3y = -9

y = -3

so, Option B x=1, y=3 and z=1 is correct

Final answer:

The physics of batting in a softball game involves concepts such as impulse, momentum, centre of mass, and contact forces. Players must properly judge these factors to successfully hit the ball without breaking the bat.

Explanation:

The subject of the question is related to the physics of batting in a game of softball. When a player is batting, concepts such as impulse, momentum, and centre of mass play a crucial role in determining the outcome. For example, a player needs to properly judge these quantities while hitting the ball to avoid breaking the bat and to ensure they either get on base or hit a home run.

Impulse can be thought of as the force applied on the ball over the duration of the contact between the bat and the ball, which ultimately changes the ball's momentum. The centre of mass refers to a point where if a force is applied, it moves in the direction of the force without rotating. The player's skill lies in applying the right amount of force at the correct angle to ensure the ball goes where he wants it to.

Moreover, if contact forces between the bat and softball are analysed, they could be explained by the interaction of charges in atoms and molecules of the bat and ball. These forces include the Coulomb force. Understanding these physical properties can give the player a beneficial scientific perspective on their game.
