Answer:

Explanation:
Given,
Width of rectangular tank, b = 1 m
Length of the tank, l = 2 m
height of the tank, d = 1.5 m
Depth of gasoline on the tank, h = 1 m


The differential form with the acceleration


acceleration in z-direction = 0 m/s²
g = 9.8 m/s²
a_y is the horizontal acceleration of the gasoline.



Hence, Horizontal acceleration of the gasoline before gasoline would spill is equal to 4.9 m/s²
Answer:
t is time in s For example, a car accelerates in 5 s from 25 m/s to 3 5m/s. Its velocity changes by 35 - 25 = 10 m/s. Therefore its acceleration is 10 ÷ 5 = 2 m/s2

Explanation:
Given:
- no. of moles of oxygen in the cylinder,

- initial pressure in the cylinder,

- initial temperature of the gas in the cylinder,

<em>According to the question the final volume becomes twice of the initial volume.</em>
<u>Using ideal gas law:</u>



A.
<u>Work done by the gas during the initial isobaric expansion:</u>




C.
<u>we have the specific heat capacity of oxygen at constant pressure as:</u>

Now we apply Charles Law:



<u>Now change in internal energy:</u>



B.
<u>Now heat added to the system:</u>



D.
Since during final cooling the process is isochoric (i.e. the volume does not changes). So,
Answer:
W = 112.58 N-unit
Explanation:
Given:
- Force F = 10 N
- Angle Q of force with x axis: 30 degrees
- distance to be moved d = 13 units along + x axis
Find:
Work Done by the force F:
Solution:
The work by force in positive x direction can only be done if the both the direction of distance traveled and direction of force are parallel vectors. Hence we compute the component of Force F in x direction F_x:
F_x = F*cos(Q)
F_x = 10*cos(30)
F_x = 8.66 N
Hence,
Work Done by force
W = F_x * d
W = 8.66 * 13
W = 112.58 N-unit
