F= ma; a= F/m
a = 26.4 N/60 kg= 0.44 m/s^2
Answer:
a) Pb= 200 PA
b).work done= -3600 joules
c).3600joules
D).the system works under isothermal condition so no heat was transferred
Explanation:
2.0 moles of a monatomic ideal gas expands isothermally from state a to state b, Pa = 600 Pa, Va = 3.0 m3, and Vb = 9.0 m3.
a). PbVb= PaVa
Pb= (PaVa)/VB
Pb= (600*3)/9
Pb= 1800/9
Pb= 200 PA
b). work done= n(Pb-Pa)(Vb-Va)
Work done= 2*(200-600)(9-3)
Work done= -600(6)
Work done=- 3600 Pam³
work done= -3600 joules
C). Change in internal energy I the work done on the system
= 3600joules
D).the system works under isothermal condition so no heat was transferred
Individuals have different traits because they are not twins so they should not be alike also because people have different genes witch would give them different traits. For example not every individual has blonde hair and blue eyes because they did not inherit those traits.
Explanation:
It is given that,
Mass of the box, m = 100 kg
Left rope makes an angle of 20 degrees with the vertical, and the right rope makes an angle of 40 degrees.
From the attached figure, the x and y component of forces is given by :
![T_{1x} =-T_1 cos (20)](https://tex.z-dn.net/?f=T_%7B1x%7D%20%3D-T_1%20cos%20%2820%29)
![T_{2x} = T_2 cos (40)](https://tex.z-dn.net/?f=T_%7B2x%7D%20%3D%20T_2%20cos%20%2840%29)
![mg_x = 0](https://tex.z-dn.net/?f=mg_x%20%3D%200)
![T_{1y} = T_1 sin (20)](https://tex.z-dn.net/?f=T_%7B1y%7D%20%3D%20T_1%20sin%20%2820%29)
![T_{2y} = T_2 sin (40)](https://tex.z-dn.net/?f=T_%7B2y%7D%20%3D%20T_2%20sin%20%2840%29)
![mg_y= -mg](https://tex.z-dn.net/?f=mg_y%3D%20-mg)
Let
and
is the resultant in x and y direction.
![R_x=-T_1 cos (20)+T_2 cos (40)+0](https://tex.z-dn.net/?f=R_x%3D-T_1%20cos%20%2820%29%2BT_2%20cos%20%2840%29%2B0)
![R_y=T_1 sin(20)+T_2 sin(40)-mg](https://tex.z-dn.net/?f=R_y%3DT_1%20sin%2820%29%2BT_2%20sin%2840%29-mg)
As the system is balanced the net force acting on it is 0. So,
.............(1)
..................(2)
On solving equation (1) and (2) we get:
(tension on the left rope)
(tension on the right rope)
So, the tension on the right rope is 1063.36 N. Hence, this is the required solution.
