Answer:
The value of change in internal energy of the gas = + 1850 J
Explanation:
Work done on the gas (W) =  - 1850 J
Negative sign is due to work done on the system.
From the first law  we know that Q = Δ U + W ------------- (1)
Where Q = Heat transfer to the gas
Δ U = Change in internal energy of the gas
W = work done on the gas
Since it is adiabatic compression of the gas so heat transfer to the gas is zero.
⇒ Q = 0
So from equation (1)
⇒ Δ U = - W ----------------- (2)
⇒ W = - 1850 J (Given)
⇒ Δ U = - (- 1850)
⇒ Δ U = + 1850 J 
This is the value of change in internal energy of the gas.
 
        
             
        
        
        
Answer:
Here the circuit in which a 4Ω resistor resistor is connected in series and two 8Ω resistor resistors are connected in parallel. Also, ammeter and voltmeter connected in series and parallel circuit respectively.
 Now,
 The maximum power of each resistance is 16 W
 The 4Ω resistor is linked in series with the circuit.
 so, P o w e r = I
 two
 R, here i is the current through the resistor resistor R
 1 6 = I
 two
 ∗ 4 Ω
 i = 2A
 Now 2A passes through parallel resistors of 8Ω resistance.
 we know that, in parallel, the potential difference must be constant,
 the current is divided into two parts, because the same resistance current in each resistance will be half. then the current through each resistor in parallel is
 2 A
 two
 .
 = 1 A
 So finally the current through the 4Ω resistor = 2 A
 current through each 8Ω resistor = 1 A

Answer:
the box has vertical force on the table
Explanation:
There can be no single isolated force, for every action there must be a force of reaction of ingual magnitude and direction, but in the opposite direction
