<span>It is the lowest velocity which a body must have in order to escape the gravitational attraction of a particular planet or other object.
Every planet has their own corresponding escape velocities. Example - Earth has escape velocity of 11.2 Km/s. It means, if you want to leave the Earth's gravitational field then it's the lowest speed which you need to acquire otherwise you wouldn't do that!
Hope this helps!</span>
Answer:
Your answer will be A
Explanation:
The Pacific Ocean is very cold, and a cup of hot chocolate is very hot (hence the name). More thermal energy entails a higher temperature, therefore the cup of hot chocolate has more thermal energy and a higher temperature.
The answer is true I think I had this question too
The emf power supply should be used for a 0.75 A recharging current is 2.25 V.
<h3>What is current?</h3>
The current is the stream of charges which flow inside the conductors when connected across the end of voltage.
Given is the battery having 1.5 V open circuit potential and internal resistance of 1 ohm.
From the Ohm's law, V =IR
R = V/I
Here, R is the proportionality constant.
To charge current I = 0.75 A
Voltage V = 0.75A x 1 ohm = 0.75 V
Total potential required is
= 1.5 +0.75
= 2.25 V
Thus, the emf power supply should be used for a 0.75 A recharging current is 2.25V.
