Force = mass x acceleration
25N = 0.40kg x acceleration
25N/0.40kg = acceleration
acceleration = 62.5 N/kg
N/kg is the equivalent of m/s²
So your acceleration is 62.5 meters per second squared
Answer: UH- What do you mean- I can answer a question if you like-
(´・ω・`)?
Explanation:
...Is this a fill in the blank question? If you wanted the time to travel a distance and knew velocity, you could divide said distance by velocity to get the time.
Time = Distance/Velocity
Answer:
Therefore the ratio of diameter of the copper to that of the tungsten is
Explanation:
Resistance: Resistance is defined to the ratio of voltage to the electricity.
The resistance of a wire is
- directly proportional to its length i.e
- inversely proportional to its cross section area i.e
Therefore
ρ is the resistivity.
The unit of resistance is ohm (Ω).
The resistivity of copper(ρ₁) is 1.68×10⁻⁸ ohm-m
The resistivity of tungsten(ρ₂) is 5.6×10⁻⁸ ohm-m
For copper:
......(1)
Again for tungsten:
........(2)
Given that and
Dividing the equation (1) and (2)
[since and ]
Therefore the ratio of diameter of the copper to that of the tungsten is
