Hi there!
Recall the conservation of momentum:

For this type of inelastic collision:

Thus, the initial momentum equal the final momentum if there are no external forces.
We can begin by writing out this problem:


Answer:
B
Explanation:
It will give the of 6 which is least of all the other forces.
4.0²+4.0² = c²

6 = c
<h2>Answer:</h2>
The correct answer is water vapor.
<h3>Explanation:</h3>
- In evaporation of water, particles with high kinetic energy tend to leave the water surface.
- Because high kinetic energy molecules move faster than others breaking bonds with other molecules.
- And escape the water to air in form of vapors.
- While the ice water contain molecules with low kinetic energy.
Answer:
0.714 m
Explanation:
From the question,
v = λf......................... Equation 1
Where v = velocity of visible light, f = frequency of visible light, λ = wave length of visible light.
make λ the subject of the equation
λ = v/f.................. Equation 2
Given: f = 4.2×10⁸ Hz
Note: Light is an electromagnetic wave, and all electromagnetic waves travels with the same speed (3×10⁸ m/s)
Constant: v = 3×10⁸ m/s
Substitute these values into equation 2
λ = 3×10⁸/4.2×10⁸
λ = 0.714 m
Answer:
The force is
Explanation:
From the question we are told that
The tangential resistive force is 
The mass of the wheel is m = 1.80 kg
The diameter of the wheel is 
The diameter of the sprocket is 
The angular acceleration considered is 
Generally the radius of the wheel is

=> 
=> 
Generally the radius of the sprocket is

=> 
=> 
Generally the moment of inertia of the wheel is mathematically represented as

=> 
=> 
Generally the torque experienced by the wheel due to the forces acting on it is mathematically represented as

Here
is the force acting on the sprocket
So


Generally the torques that will cause the wheel to move with
is mathematically represented as

So
