(i) I avoided drought by closing the window

(ii) I avoided error due to parallax when reading the meter rule

Tabulate.

Period-

(i)is the time taken on complete one oscillation/circle or to.

(ii)unit is second (s)

(iii)it is Oscillation motion

(iv)it is when a body moves in a to and fro manner

-Frequency of oscillation-

(i)is the number of complete oscillation in one second

(ii) frequency; unit Hertz (Hz)

(iii)it is Rotation motion

(iv)it is when a body turns about an axis through the body

(1bii)

E= 25J

Extension= 6.7×10-²m

Force constant (k) = ?

E= 1/2ke²

2E = ke²

k = 2E/e²

k = 2x 25/(0.067)²

k = 50/0.00449

k = 11135.9Nm-¹

(i)I ensured tight connections on all terminals

(ii) I avoided error due to parallax on the ammeter

(3bi)Period refers to the amount of time it takes a wave to complete one full cycle of oscillation or vibration. Frequency, on the contrary, refers to the number of complete cycles or oscillations occur per second. Period is a quantity related to time, whereas frequency is related to rate. Period simply refers to the time for something to occur periodically, whereas frequency means how often that happens.

1. Thermodynamics, science of the relationship between heat, work, temperature, and energy. In broad terms, thermodynamics deals with the transfer of energy from one place to another and from one form to another.

2. THERMODYNAMIC SYSTEM: A system is defined as a region in space containing a quantity of matter whose behaviour is being investigated. This quantity of matter is separated from its surroundings by boundary, such as the walls of a vessel.
