Answer:
h = 13.06 m
Explanation:
Given:
- Specific gravity of gasoline S.G = 0.739
- Density of water p_w = 997 kg/m^3
- The atmosphere pressure P_o = 101.325 KPa
- The change in height of the liquid is h m
Find:
How high would the level be in a gasoline barometer at normal atmospheric pressure?
Solution:
- When we consider a barometer setup. We dip the open mouth of an inverted test tube into a pool of fluid. Due to the pressure acting on the free surface of the pool, the fluid starts to rise into the test-tube to a height h.
- The relation with the pressure acting on the free surface and the height to which the fluid travels depends on the density of the fluid and gravitational acceleration as follows:
P = S.G*p_w*g*h
Where, h = P / S.G*p_w*g
- Input the values given:
h = 101.325 KPa / 0.739*9.81*997
h = 13.06 m
- Hence, the gasoline will rise up to the height of 13.06 m under normal atmospheric conditions at sea level.
While sliding down a hill in a sled, the force of gravity causes the sled to accelerate down the hill. The force of friction eventually causes the sled to stop. the friction force partly cancels some of the gravity force pulling the sled down. These two forces affect many motions on Earth.
True I’m not sure how to explain sorry
The number of outcomes in the compliment of the event are 0.54
<h3>Concept and calculation</h3>
No of strawberry plants in the field = 259259
No of plants that are ready for picking = 142142
so no of outcomes = 142142/ 259259 = 0.54 outcomes
<h3>Understanding of probability</h3>
The area of mathematics that deals with probability is called probability theory.
Probability is a concept that can be interpreted in a variety of ways, but probability theory tackles the idea in a rigorous mathematical way by expressing it through a series of axioms.
Typically, these axioms formalize probability in terms of a probability space, which links a collection of outcomes known as the sample space to a measure taking values between 0 and 1. An event is any defined subset of the sample space.

<span>Gvn that,
Radius r = 1.65cm
then the Diameter d = 3.3 cm
Volume V = 4/3pi*(D/3)^3
= 4/3*3.14*(3.3)^3/8
= 4/3*3.14*35.937/8
= 4/3*3.14*4.492125
= 4/3*14.1052725
= 56.421.9/3
= 18.80703 dm^3
We know that gravity g=9.806m/s^2
p pt = 2.14 * 104 kg/m^3 = 21.4
p hg = 1.36 * 104 kg/m^3 = 13.6
Real Weight Wr = V*p pt*g
= 18.80703*21.4*9.806
= 3946.625 N
Buoyant force Fb= V*p hg*g
= 18.80703*13.6*9.806
= 2508.136 N
Apparent weight = Wr-Fb
= 3946.625-2508.136
= 1438.489 N
Therefore Apparent weight is 1438.489 N</span>
