Eating eggs for breakfast increases grades. What is the constant?
Feliz [49]

Answer and Explanation:

The answer would be: <u>Breakfast</u>

<u></u>

Breakfast would be the constant of this scenario because this doesn't change. The time of day (for eating eggs) will always be in the morning, so that wouldn't change.

Eating eggs would be the independent variable because you can change this value. This could be a different food or an amount of the food that is being eaten.

The grades would be the dependent variable because the score <em>depends</em> on the eating of eggs.

What is surface tension? How does surface tension result from intermolecular forces? How is it related to the strength of interm
Bond [772]

Answer:

Surface tension is the tendency of liquid surfaces to shrink into the minimum surface area possible.

Surface tension is caused by effects of intermolecular forces at liquid interface.

Surface tension increases as intermolecular forces increases.

Explanation:

  • Surface tension is the tendency of liquid surfaces to shrink into the minimum surface area possible. It can also be seen as the energy required to increase the surface of a liquid by a unit amount.
  • Surface tension is caused by the mediating effects of intermolecular forces at the liquid interfaces. Example in water, surface tension is caused by the mediating effect of the force between hydrogen and oxygen molecules. Liquids tends to reduce their surface area because of inward attarction of the liquid molecules.
  • Surface tension increases as intermolecular forces increases. Also, surface tension decreases as intermolecular forces decreases.

A 0.150-kg ball traveling horizontally on a frictionless surface approaches a very massive stone at 20.0 m/s perpendicular to wa
Hitman42 [59]

Answer:

The magnitude of the change in momentum of the stone is 5.51kg*m/s.

Explanation:

the final kinetic energy = 1/2(0.15)v^2

                1/2(0.15)v^2  = 70%*1/2(0.15)(20)^2

                              v^2 = 21/0.075

                              v^2 = 280

                                 v = 16.73 m.s

if u is the initial speed and v is the final speed, then:

u = 20 m/s and v = - 16.73m/s

change in momentum = m(v-u)

                                     = 0.15(- 16.73-20)

                                    = -5.51 kg*m.s

Therefore, The magnitude of the change in momentum of the stone is 5.51kg*m/s.

A car tire is filled with air at pressure 325000 pa at 303 K. When the tire cools,its pressure reduces to 299000 Pa. What is the
max2010maxim [7]

Answer:

new temperature of the tire will be 278.76 K

Explanation:

when the temperature increases, the particles will have greater kinetic energy and also the pressure will be increase for the gas particles.

so when the temperature increases, pressure  will also increase  and vice versa

 T is directly proportional to P

T1  = initial temperature= 303 k

P1= Initial pressure =  325000 pa

T2= Final temperature=  ?

P2= Final pressure =   299000 pa

mathematically

P1/T1= P2/T2

T2= P2 x T1/P1

T2 = 299000 x 303/ 325000=  278.76 k
