Answer

1.negative work

2. kinetic energy and motion of ball

3. ball lost energy

4. kinetic energy

Explanation:

1:when you catch a ball that time their are two forces involved

a. force exerted by ball on your hand

b. Force exerted by you on ball  to stop it. Here the direction of force applied by you on the ball is in opposite direction to the motion of ball. it means direction of applied force and displacement of ball are in opposite direction it means work done by you on baseball is negative a.

2.When we catch a baseball that time we change its kinetic energy, force and its motion. A moving ball has kinetic energy and to stop the ball we have to change kinetic energy of ball. When we catch a baseball the kinetic energy of ball is transferred to our hand. When we catch a ball our hand moves in backward direction with ball because our hand gain energy.

3. Baseball lost energy and this energy is transferred to our hand.

4. Baseball has kinetic energy

Expand (2x + y) (2x - y).​
KiRa [710]

Answer: 4x²-y²

Explanation:

FORMULA

a²-b²=(a+b)(a-b)

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

(a+b)(a-b)=a²-b²

(2x+y)(2x-y)=(2x)²-(y)²

                  =4x²-y²

How does an acid–base indicator react when placed in an acidic solution?
s344n2d4d5 [400]
It depends on the indicator, and the pH range over which it will experience a colour change. Some indicators will change colour<span> in an acidic solution, others will not. For example, blue litmus paper will turn red in an acidic solution, but red litmus paper will not change colour. The test would be inconclusive with red litmus paper, since it does not change colour in an acid and in a neutral solution.</span>
