Answer:
Explanation:Advatages
1..Its takes precise reading accurate
2. it is moveable because of its small weight
3.It is easy to read and can be kept inside water
Disadvantages
1. It breaks easily because of its small size
2. If broken there can be risk of exposure to mercury chemicals.
Hope it helped you.

Today this question is about science,or chemistry.
A. Acceleration is a correct answer. Acceleration is a rate of change in velocity.
It change in velocity/change in time. Next, to slope will be indicated by the acceleration.
B Change in position is a incorrect answer.
C. Velocity is a incorrect answer. Velocity is a displacement of an object during a specific unit of time. It can used two measurements are needed to determine velocity. It displacement or by the time. Displacement it includes a direction, so the velocity will also includes a direction. It can used speed with direction. Velocity it can be average velocity or an instantaneous velocity.

Have a great day!
Thanks!
Speed. units m/s
Because you want to know how fast he can run without involving any direction thus the best is speed
speed = distance / time
Answer:
-6.34 degrees.
Explanation:
Because this is a collision we can use the formula of linear momentum conservation.
The pin has an angle so it has two components of velocity, so:
applying the first formula:
The angle is given by:
the angle is -6.34 degrees.
Answer:
17.284 rad/s^2
Explanation:
F = 337 N
R = 0.398 m
M = 98 kg
let the angular acceleration is α
torque = I x α = F x R
Where I is the moment of inertia
I = 1/2 MR^2 = 0.5 x 98 x 0.398 x 0.398 = 7.76 kg m^2
So,
7.76 x α = 337 x 0.398
α = 17.284 rad/s^2
