<h2>Answer: electrostatic and gravitational force </h2><h2 />

Mechanical energy remains constant (conserved) if only <u>conservative forces</u> act on the particles.  

In this sense, the following forces are conservative:  

-Gravitational  

-Elastic

-Electrostatics  

While the Friction Force and the Magnetic Force are not conservative.

According to this, mechanical energy is conserved in the presence of electrostatic and gravitational forces.

USPshnik [31]

Answer;

= 90600 m/s...

Explanation;

velocity of ball = 96 mi/hr = 42.916 m/s...  

velocity of bat = -56mi/hr = -25.034m/s.. ( note the negativity here..)  

time = 0.75 millisec = 0.75 * 10^-3 sec  

acceleration = (velball - velbat) / time

                     = (42.916 - (-25.034)) / (0.75 * 10^-3)

                     =90600 m/s

What type of path does a moving object follow in the absence of a force?.
Amanda [17]

Answer:

When there is no force acting on a body then a moving object move in a straight line with constant velocity and an object in rest stays in rest.

The same amount of substance was added to four beakers of water. The treatments were placed in the chart.
denis-greek [22]

Answer:

C: Solutions W and Y have greater solubility than solutions X and Z.

Explanation:

Temperature and pressure affect the solubility of a solution as follows:

- the higher the pressure, the greater the solubility (because more pressure means more collisions between the molecules, so this improves the solubility)

- the higher the temperature, the greater the solubility (because higher temperature means higher kinetic energy of the molecules, so more collisions, and so this improves the solubility)

Therefore, considering these two factors, the solutions with greater solubility must be W (which has high pressure) and Y (which has high temperature).

What are the characteristics of Parallel circuit??<br>​
NikAS [45]

Answer:

A parallel circuit has two or more paths for current to flow through.

Voltage is the same across each component of the parallel circuit.

The sum of the currents through each path is equal to the total current that flows from the source.

A soccer ball is released from rest at the top of a grassy incline. After 8.6 seconds, the ball travels 87 meters and 1.0 s afte
Arturiano [62]

Answer:

a) a = 2.35 m/s^2

Explanation:

(a) In order to calculate the magnitude of the acceleration of the ball, you use the following formula, for the position of the ball:

x=v_ot+\frac{1}{2}at^2     (1)

x: position of the ball after t seconds = 87 m

t: time  = 8.6 s

a: acceleration of the ball = ?

vo: initial velocity of the ball = 0 m/s

You solve the equation (1) for a:

x=0+\frac{1}{2}at^2\\\\a=\frac{2x}{t^2}

You replace the values of the parameters in the previous equation:

a=\frac{2(87m)}{(8.6s)^2}=2.35\frac{m}{s^2}

The acceleration of the ball is 2.35 m/s^2
