Answer:
The specific gravity of the unkown liquid is 15.
Explanation:
Gauge pressure, at the bottom of the tank in this case, can be calculated from
where and
are the height of the column of oil and the unkown liquid, respectively. Writing for
, we have
Relative to water, the unknow liquid specific weight is 15 times bigger, therefore this is its specific gravity as well.
Answer:
The value of tangential acceleration 40
The value of radial acceleration
Explanation:
Angular acceleration = 50
Radius of the disk = 0.8 m
Angular velocity = 10
We know that tangential acceleration is given by the formula
Where r = radius of the disk
= angular acceleration
⇒ 0.8 × 50
⇒ 40
This is the value of tangential acceleration.
Radial acceleration is given by
Where V = velocity of the disk = r
⇒ V = 0.8 × 10
⇒ V = 8
Radial acceleration
This is the value of radial acceleration.
