Answer:
V(car) = V(truck) at t = Dt/2
acceleration = v(car) = D/t^2
Explanation:
acceleration = v(car) = D/t^2
Since the average velocities must be the same, the car's final velocity must be twice the trunk velocity assuming the car start with zero velocity, since acceleration remain the same throughout the journey velocities at half-time point must be equal.
Daguerreotype is defined as the
first practical photographic process which was introduced in Paris on January
7, 1839. To make the image permanent, Daguerre used salt solution. The result
of his introduced process is a finely defined image with surface which is
delicate. The major benefit of daguerreotype is if the images are correctly
preserved, the pictures could last forever. Aside from this, since it produces superior
quality of outline, it is thus suitable for portraitures.
Answer:

Explanation:
As we know that the equation of SHM is given as

now we have

now at t = 2.3 s we have


Answer:0.2mm
Explanation:
The length of one VSD=8/10=0.8mm
The least count of the instrument is the difference between the length of one MSD and length of one VSD
The length of inebriated MSD=1mm
Therefore,
The least count=1-0.8=0.2mm
