Answer:
0.119 s
Explanation:
Given that
Lets take final speed of the softball after covering 4.8 m = V
We know that
Also We know that
Putting the value of V ,U and a in the previous equation We get
Therefore slide time will be 0.119 s
Fire is it that lives if it is fed, and dies if you give it a drink.
<h3><u>
Explanation:</u></h3>
Fire is very essential part of human life. It is used for cooking food and for other important activities. Without fire we cannot not survive. Something or the other should be heated before consumption and this can be achieved only with fir. It is also used in the darker places for viewing many things around us.
Thus, fire can survive if we give fuel or any wooden pieces and when water is poured on it it will turn off. Hence Fire is the one that survives when it is fed and dies when water is given as a drink to it.
Answer:
B
Explanation:
F = ma , a = F/m
a1 = F/10 and a2 = F/4
Since Force is constant, a2 will we greater than a1
Answer:
the greater the height of an object the *greater* its gravitational potential energy
greater
Answer and Explanation:
Internal Energy:
Internal energy associated to a system is the total amount of energy of a system excluding both the kinetic and potential energies as a whole for any external effects and is only accountable for any change in the energies of the system due to the internal order or states. It can be considered as that energy of the system essential to make it ready for any provided state.
Specific heat:
It is the specific amount of heat that is contained in a unit mass of any substance needed to bring about [tex]1^{\circ} rise in its temperature.
Entropy:
It can be defined as the degree of disorientation of the molecules or the extent of disorder of the system. It is the lack in thermal energy of the system to get converted into work (mechanical).
Temperature:
The measure of the heat intensity of a substance on a given standard scale.
