Answer:
P.E = 25.48 Joule
Explanation:
Here,
mass (m) = 2kg
height (h) = 1.3m
g = 9.8m/s^2
P.E = mgh
= (2) (9.8) (1.3)
P.E = 25.48 Joule
Thus, the potential energy of a 2kg plant that is on a windowsill 1.3m high is 25.48 Joule

Answer: The answer is C.) 25 m/s^2.
Explanation: If you input 5 as s, you would have to use the exponent 2. This means that you have to multiply 5 by 5. 5 x 5= 25.
Edit: Also, because the surface is frictionless, it will make the object go faster too. Nothing can really slow it down unless something blocks it.
Hot body will lose heat from it, and that heat will goes out from it through radiation, so it's temperature will decrease after some time.
In same manner, cold body will take the heat, and it's temperature will increase
Hope this helps!
Answer:
The acidic or the basic nature of a substance can be determined using a pH indicator. If the pH indicator , shows a pH value less than 7 , the substance is acidic. Lower the pH , high is the acidic nature.
