In physics, acceleration describes how an object's velocity changes over time. Whenever the speed of an object shifts, it's considered to be accelerating. To calculate acceleration here:
acceleration = (8.2 - 3.5) / 1.5 = 3.1 m/s²
I trust this answers your question.
Answer:
The wire length is 32 inches.
Explanation:
According to the question,
The pipe's length = 60 inches
The pipe's circumference = 4 inches
Now,
The wire wraps around the pipe for 8 complete turns.
Now, with 2πr = 4, we find that
r = 2/π
Thus,
The radius, r = 2/π
The wire's length can be calculated as,
Length = Number of turns x Circumference of the pipe
So, length of wire = 8 x 4 = 32 inches.
Consequently, the wire length is 32 inches.
Answer:

Explanation:
Data provided
initial velocity v₀=20 cm/s at time t=3s
final velocity vf=0 at time t=8 s
Required
Average Acceleration for the interval from 3s to 8s
Solution
Acceleration can be defined as the first derivative of velocity concerning time
Answer:
The required energy remains identical in both scenarios since the specific heat capacity (Cp) does not change with varying pressure.
Explanation:
Given;
initial temperature, t₁ = 50 °C
final temperature, t₂ = 80 °C
Temperature change, ΔT = 80 °C - 50 °C = 30 °C
Pressure for scenario one = 1 atm
Pressure for scenario two = 3 atm
The energy needed in both scenarios is expressed as;

Where;
Cp denotes specific heat capacity, which only varies with temperature and remains unaffected by pressure.
Hence, the energy required remains the same for both scenarios since specific heat capacity (Cp) is pressure-independent.
The total duration from the stone's drop to the echo being heard is 8.9 seconds. The sound takes 0.9 seconds to reach the listener, meaning it takes the stone 8 seconds to descend to the well's bottom. Using gravitational acceleration, the well's depth calculates to be approximately 313.6 meters.
