A wire is 4m long and has a mass 0.2kg. The wire is kept horizontally....
Given:
Length of wire (L) = 4m
Mass of wire (m) = 0.2kg
Time taken for four trips (T) = 0.8s

To find:
Tension in the wire

Analysis:
When a pulse is generated in a taut wire, it travels back and forth along the wire. The speed at which the pulse travels is given by the formula:

v = √(T/μ)

Where:
v is the velocity of the pulse,
T is the tension in the wire, and
μ is the linear mass density of the wire.

The linear mass density (μ) is given by the formula:

μ = m/L

Where:
m is the mass of the wire, and
L is the length of the wire.

The time taken for the pulse to travel back and forth along the wire is given by the formula:

T = 2L/v

Where:
T is the time taken,
L is the length of the wire, and
v is the velocity of the pulse.

In this case, we are given the values of L, m, and T. We can use these formulas to find the tension in the wire.

Solution:

Step 1: Calculate the linear mass density (μ)
μ = m/L
= 0.2kg / 4m
= 0.05 kg/m

Step 2: Calculate the velocity of the pulse (v)
v = √(T/μ)
= √(0.8s / 0.05 kg/m)
= √(16 m²/s²)
= 4 m/s

Step 3: Calculate the tension in the wire (T)
T = 2L/v
= 2 * 4m / 4 m/s
= 8 N

Therefore, the tension in the wire is 8 N.
