Variables in physics often include a subscript. What are subscripts used for in physics?

Physics

Answer:

C.) To indicate different versions of the same variable.

Explanation:

Variables in physics often include a subscript. These subscripts are used for indicating different versions of the same variable in physics.

Basically, subscripts are used to represent the beginning (initial) and ending (final) position or point of a variable in physics.

For example, we would look at Gay Lussac' Law of gases.

Gay Lussac law states that when the volume of an ideal gas is kept constant, the pressure of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Gay Lussac's law is given by;

PT = K

\frac{P1}{T1} = \frac{P_{2}}{T_{2}}

Where;

T_{1} represents the initial temperature.

T_{2} represents the initial temperature.

P_{1} represents the initial pressure.

P_{2} represents the initial pressure.

Note: 1 and 2 are the subscript while T and P are the variables.

A 4-kilogram cat is resting on top of a bookshelf that is 3 meters high. What is the cat’s gravitational potential energy relati
hichkok12 [17]
The answer is 117.6 J

The potential energy of the object is actually its stored energy:

<span>E = m · g · h
E - the potential energy of the object,
m - the mass of the object,
g - acceleration due to gravity,
h - the height of the object.

m = 4 kg
g = 9.8 m/s</span>²
h = 3 m

E = 4 * 9.8 * 3 = 117.6 J

Derive a general formula for projectile motion with the object launched at an angle
vagabundo [1.1K]

Answer:

  y = x tan θ - (g / 2v₀² cos² θ) x²

Explanation:

An equation is called a general formula that relates the position on the x-axis and the height on the body's axis.

Let's write the position on each axis

X axis. No acceleration

         x = v₀ₓ t

Y Axis.  There is the acceleration of gravity

        y = v_{oy} t - ½ g t²

Let's clear the time in the first equation and substitute in the second

       y = v₀ sin θ  (x / v₀ₓ) - ½ g (x / v₀ₓ)²

       y = v₀ sin θ / v₀ cos θ x - ½ g x² / v₀² cos² θ

       y = x tan θ - (g / 2v₀² cos² θ) x²

This is the trajectory equation in projectile launching

A 1 500-kg car rounds an unbanked curve with a radius of 52 m at a speed of 12.0 m/s. What minimum coefficient of friction must
Sergio039 [100]

Explanation:

The centripetal force F_c on the car must equal the frictional force f in order to avoid slipping off the road. Let's apply Newton's 2nd law to the y- and x-axes.

y:\:\:\:\:N - mg = 0

x:\:\:F_c = f \Rightarrow \:\:\:m \dfrac{v^2}{r} = \mu N

or

m \dfrac{v^2}{r} = \mu mg

Solving for \mu,

\mu = \dfrac{v^2}{gr} = \dfrac{(12.0\:\frac{m}{s})^2}{(9.8\:\frac{m}{s^2})(52\:m)} = 0.28
