Answer:
Explanation:
They are called "fictitious" because the physical forces leading to motion are accounted for in the construction of the non-inertial frame rather than being included as a "real force" term in the equation of motion. Instead, the terms are built into the equation of motion itself in a non-inertial frame.

im very con fused on what you mean by this
Explanation:
Answer:
Angular velocity = 0.105 rads⁻¹
speed of tip = 0.00105 ms⁻¹
Explanation:
A second hand turns 2π rad each 60 sec
Thus: it has an angular speed given by
ω = 2π/T = 2π/60 = π/30 = 0.105 rad s⁻¹
The speed of the tip is given by
V= rω = 0.01 m × (0.105 rads⁻¹)
= 0.00105 ms⁻¹
Answer:
Explanation:
For convenience, let's represent the thermal expansion coefficient by , i.e. .
Given that, for steel °,
initial length, , initial temperature, °, and the final temperature, °.
Let the length of the rod at ° be .
Now, change in length,
Hence, the length of the rod at ° be .
