Answer:

W=-251096.465\ J negativesign denotes thatthe work is consumed by the system.

Explanation:

Given:

Isothermal process.

initial temperature, T_1=300\ K

initial pressure, P_1=150kPa

initial volume, V_1=0.2\ m^3

final pressure, P_2=800\ kPa

<u>The work done during an isothermal process is given by:</u>

W=P_1.V_1\times ln(\frac{P_1}{P_2} )

W=150\times 1000\times \ln\frac{150}{800}

W=-251096.465\ J negativesign denotes thatthe work is consumed by the system.

A 1.80-kg object is attached to a spring and placed on frictionless, horizontal surface. A horizontal force of 15.0 N is require
kirill [66]

Answer:

Explanation:

(a) Force constant = force/displacement = 15/0.2

=75 N/m

(b) For SHM with spring, the angular frequency = sqrt ( force constant / mass )

= sqrt ( 75 / 1.8 )

= 6.455

Frequency = Angular frequency / 2pi

= 1.03Hz

(c) Maximum speed is when object's potential energy is at minimum.

1/2*mass*speed^2 = 1/2*force constant*displacement^2

speed^2 = 75*0.2^2/1.8 = 1.67

speed = sqrt (1.67)

= 1.29 m/s

(d) It occurs at x=0

(e) Maximum acceleration = Force / m = 15/1.8

= 8.33 m/s^2

(f) It occurs at x=0.2m

1. The potential difference between the terminals a cell in open circuit is 2.2volt. With resistance of 5ohm across the terminal
nadya68 [22]

Explanation:  

10 /9 Ω

potential difference across the cell in open circuit is the emf of the cell.

Hence, emf E=2.2V

when, circuit is closed, potential difference across cell is given by V=E−Ir

And,

I= E/ R+r

Hence, V= E− Er/ R+r

⟹ V= ER/ R+r

⟹ 1.8= 2.2×5 /5+r

⟹9+1.8r=11

⟹ r= 2/  1.8  Ω

⟹ r= 10/9  Ω
