B) B. is the point where it has maximum potential energy.
Explanation:
- This an example of projectile motion.
- In projectile motion, the path of an object is illustrated in the picture given. In the given picture, the minimum kinetic energy and the maximum potential energy is at B
- B is the point where the object, for example, the ball is reaching its point of minimum kinetic energy which means that after this point the object's downward motion starts.
- Hence, the transition from the upward motion to the downward motion is the point where it has the maximum potential energy.
Answer:
Explanation:
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t
is the initial concentration
Given:
75 % is decomposed which means that 0.75 of is decomposed. So,
= 1 - 0.75 = 0.25
t = 60 min
k = 0.023 min⁻¹
Considering the expression for half life as:-
Where, k is rate constant
So,
Answer:
The answer is A
Explanation:
That is the only answer that even remotely resembles an ultrasound hope this answered your question.
Answer:
true
Explanation:
H2O : 2 covalent bonds are established between O atom and 2 H atom (H--O--H) by mutual shearing of their valence electrons.
It offers a route to reducing sodium intake.
