Answer:
Rotational inertia of the object is given as
Explanation:
As we know that the acceleration of the object on inclined plane is given as
now we know that velocity at any instant of time is given as
now we know that if the graph between velocity and time is given then the slope of the graph will be same as acceleration
so here we have
now from the graph slope of the graph is given as
now rotational inertia is given as
Explanation:
Gravitational potential energy = mgh = (5)(9.81)(7) = 343.35J.
Answer:
The temperature rises by 0.52K
Explanation:
Detailed explanation and calculation is shown in the image below
Answer:
16.2 s
Explanation:
Given:
Δx = 525 m
v₀ = 0 m/s
a = 4.00 m/s²
Find: t
Δx = v₀ t + ½ at²
525 m = (0 m/s) t + ½ (4.00 m/s²) t²
t = 16.2 s
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:
