Answer:
C. Adding some of the unknown liquid to red litmus paper.
Explanation:
Since the student doesn't know what the liquid is, it is not safe to experiment with it by boiling, cooling, or adding water to it. The safest option would be to add a small bit of the liquid to the litmus paper, which will identify the liquid as neutral, basic, or acidic.

Answer:
From what I know they postponed the movies that were suppose to come out.
Option (ii) B is the correct option. The object on the moon has greater mass.
To resolve this, utilize the formulas Force = Mass * Acceleration.
The equation can be used to find the mass given the force in Newtons, using 9.8 m/s² for the acceleration of gravity of the earth and 1.6 m/s² for the moon.
Calculating the mass on earth:
30 N = 9.8 m/s² * mass
This results in a mass of 3.0 kg for the object on Earth.
Calculating the mass of the moon:
30 N = 1.6 m/s²2 * mass
Thus, the moon's object has a mass of 19. kg.
This can be explained by the fact that the earth has a stronger gravitational pull than the moon, producing more force per kilogram of mass. As a result, the moon's mass must be bigger to produce the same amount of force at a lower acceleration from gravity (1.6 m/s² vs. 9.8 m/s²).

The charge transported as a result of charging is 43200C .
we can note the following data from the statement :
Current (i) = 3A
Time interval (t) = 4 hrs = 14400secs
As we know ,
Current is defined as the rate of flow of the charges between two points when a potential difference is applied between them.
Mathematically , it can be written as
Current(i) = charge (q)/ time(t)
Q = i × t
= 3 × 14400
= 43200 C
By dividing the value of the current passed through the circuit by the time for which the charge is passed gives out the value of the charge passed .
