A baseball is thrown high into the air. As it travels upwards it loses speed and slowly comes to a stop high above the grove wha
Aleks [24]

Answer:

Potential energy

Explanation:

The thrown baseball is converting from kinetic energy into potential energy. When it finally stops at a particular height, it attains its maximum potential energy at the position or point.

  • Potential energy is the energy at rest of body.
  • Kinetic energy is the energy due to the motion of body.

The more a body speeds, the higher its kinetic energy attained.

As a body comes to rest, at a height, it attains potential energy.

The body during flight decreases in kinetic energy but increases its potential energy due to gravity pulling it to rest.

Which bond will each pair of elements form?
jok3333 [9.3K]

Explanation: Sodium is a metal with a low electronegativity it will form an ionic bond with a non metal with a high electronegativity.

Both Florine and Sulfur are non metals with high electronegativity.

Neon is a noble gas family VIII A and normally doesn't form any bonds at all.

How many ml of 0.5M of HNO3 would be needed to react with 85ml of 0.75M of KOH
olganol [36]

Answer: 127.5ml

Explanation:

To calculate the volume of acid, we use the equation given by neutralization reaction:

n_1M_1V_1=n_2M_2V_2

where,

n_1,M_1\text{ and }V_1 are the n-factor, molarity and volume of acid which is HNO_3

n_2,M_2\text{ and }V_2 are the n-factor, molarity and volume of base which is KOH.

We are given:

n_1=1\\M_1=0.5M\\V_1=?mL\\n_2=1\\M_2=0.75M\\V_2=85mL

Putting values in above equation, we get:

1\times 0.5\times V_1=1\times 0.75\times 85\\\\V_1=127.5mL

Thus 127.5 ml of 0.5M of HNO3 would be needed to react with 85ml of 0.75M of KOH
