A. Discovering a quick way to handle a new problem
Answer:
28.81 m
Explanation:
Ff = -123
m * a = -123
(29.8+10.3) * a = -123
a = -123/40.1 = -3.07
We know,
v^2 = u^2 + 2as
0^2 = 13.3^2 + 2*(-3.07)*s
s = 176.89/6.14 = 28.81

Answer:
0.0000109261200583 s
0.0109261200583
Explanation:
= Distance from right ear = 3 m
s = Distance between ears = 15 cm
v = Speed of sound in air = 343 m/s
Distance between the left ear and the bird

Time

Time difference would be

The time difference is 0.0000109261200583 s
Time period is given by

The ratio is

The ratio is 0.0109261200583
When an object absorbs an amount of energy equal to Q, its temperature raises by

following the formula

where m is the mass of the object and

is the specific heat capacity of the material.
In our problem, we have

,

and

, so we can re-arrange the formula and substitute the numbers to find the specific heat capacity of the metal:
