Answer:For a perfectly elastic collision, the final velocities of the carts will each be 1/2 the velocity of the initial velocity of the moving cart. For a perfectly inelastic collision, the final velocity of the cart system will be 1/2 the initial velocity of the moving cart.
Explanation:
Answer with Explanation:
We are given that
Resistance of solenoid,R=4.3 ohm
Magnetic field,B=
Current,I=4.6 A
Diameter of wire,d=0.5 mm=
Radius of wire,r=
Radius of solenoid,r'=1 cm=
Resistivity of copper,
We know that
Where 
Using the formula
Number of turns of wire=
Number of turns of wire=
Hence, the number of turns of the solenoid,N=799
Magnetic field in solenoid,B=
Length of solenoid=12.5 cm
1m=100 cm
The various contributions involved till the chapati is made is given below.
<h3>What is food?</h3>
The substance that we intake for the body to charge up by giving nutrients is called the food.
Wheat is a staple food. We make chapati from flour obtained from the wheat grains.
The various contributions involved till the chapati is made is given below.

Answer:
<u>400</u> J work is done BY the engine.
The internal energy of the gas is <u>620</u> J
Explanation:
The given information are;
The heat added to the cylinder = 620 J
The force applied by the piston of the engine = 8.0 kN = 8,000 N
The distance over which the force moves (the piston) = 5.0 cm = 0.05 m
The work done (by the engine) = Force × Distance = 8,000 N × 0.05 m = 400 J
The internal energy is the sum of the kinetic and potential energy of the system
Therefore, given that the internal energy, U, is the sum total of the energy in the system
∴ U = The heat supplied to the system = 620 J
Which gives;
<u>400</u> J work is done BY the engine.
The internal energy of the gas is <u>620</u> J.
Answer:
Explanation:
According to heisenberg uncertainty Principle
Δx Δp ≥ h / 4π , where Δx is uncertainty in position , Δp is uncertainty in momentum .
Given
Δx = 1 nm
Δp ≥ h /1nm x 4π
≥ 6.6 x 10⁻³⁴ / 10⁻⁹ x 4 π
≥ . 5254 x ⁻²⁵
h / λ ≥ . 5254 x ⁻²⁵
6.6 x 10⁻³⁴ /. 5254 x ⁻²⁵ ≥ λ
12.56 x 10⁻⁹ ≥ λ
longest wave length = 12.56 n m
