To solve this problem we will apply the concepts related to the Magnetic Force, this is given by the product between the current, the body length, the magnetic field and the angle between the force and the magnetic field, mathematically that is,
Here,
I = Current
L = Length
B = Magnetic Field
= Angle between Force and Magnetic Field
But
Rearranging to find the Magnetic Field,
Here the force per unit length,
Replacing with our values,
Therefore the magnitude of the magnetic field in the region through which the current passes is 0.0078T
Answer:
= 3768 m/ms
Explanation:
For this exercise we will use the relationships of the moment
I = ∫ F dt = Δp
The expression for strength is
F = at - bt3
Let's replace and calculate the momentum
I = ∫ (at - bt3) dt
I = a t2 / 2 - b t4 / 4
We evaluate between the initial time of zero and the final time of 2.74 ms
I = ½ a (2.74)² - ¼ b (2.74)⁴
I = ½ 1500 7.51 - ¼ 20 56.36
I = 5632.5-281.8
I = 5350.7 N ms
Now we use the momentum relationship with the moment
I = Δp
I = m - m v₀
I = m - 0
= I / m
= 5350.7 / 1.42
= 3768 m / ms
= 3768 m / ms (1000 ms / 1 s) = 3.768 106 m / s
Answer:
The value is
Explanation:
From the question we are told that
The mass of bullet is
The mass of the block is
The spring constant is
The amplitude is
Generally according to the conservation of momentum is
given that the block was at rest we have that
Now the angular velocity of the both bodies is mathematically represented as
Given that the system after collision set into oscillation
The maximum linear velocity of the system after impact is mathematically represented as
From above equation

Answer: The hierarchical formation model suggests that galaxies may have been formed by subsequent mergers of smaller galaxies and that today each galaxy houses at least a supermassive black hole.
Explanation: During a fusion of galaxies, the stars that composes it suffer the tidal force, intensifying your action as the galaxies approaching. When two galaxies merges themselves, the astronomers believes that they loss a huge part of their mass, forming the supremassive black hole, that stays in the middle of the galaxie.
The supermassive black holes are originated from the evolution of high mass stars. They were formed by huge clouds of gas or clusters of millions of stars that collapsed on their own gravity when the universe was still much younger and denser.
