Explanation:
From the question we are told that
The diameter of solenoid 1 is 
The length of solenoid 1 is 
The number of turns of solenoid is 
The diameter of solenoid 2 is 
The length of solenoid 2 is 
The number of turns of solenoid 2 is 
Generally the magnetic in a solenoid is mathematically represented as
From this equation we see that
Here C stands for constant

The protons and electrons are held in place on the x axis.
The proton is at x = -d and the electron is at x = +d. They are released at the same time and the only force that affects movement is the electrostatic force that is applied on both subatomic particles. According to Newton's third law, the force Fpe exerted on protons by the electron is opposite in magnitude and direction to the force Fep exerted on the electron by the proton. That is, Fpe = - Fep. According to Newton's second law, this equation can be written as
Mp * ap = -Me * ae
where Mp and Me are the masses, and ap and ae are the accelerations of the proton and the electron, respectively. Since the mass of the electron is much smaller than the mass of the proton, in order for the equation above to hold, the acceleration of the electron at that moment must be considerably larger than the acceleration of the proton at that moment. Since electrons have much greater acceleration than protons, they achieve a faster rate than protons and therefore first reach the origin.
Answer: 
Explanation:
According to the described situation we have the following data:
Horizontal distance between lily pads: 
Ferdinand's initial velocity: 
Time it takes a jump: 
We need to find the angle 
at which Ferdinand jumps.
In order to do this, we first have to find the <u>horizontal component (or x-component)</u> of this initial velocity. Since we are dealing with parabolic movement, where velocity has x-component and y-component, and in this case we will choose the x-component to find the angle:
(1)
(2)
(3)
On the other hand, the x-component of the velocity is expressed as:
(4)
Substituting (3) in (4):
(5)
Clearing :
This is the angle at which Ferdinand the frog jumps between lily pads
Fat-soluble DDT accumulates in the fats of milk and from there can be transferred to children.
Answer:
The expression of gravitational field due to mass 
at a distance 
Explanation:
We have given mass is 
Distance of the point where we have to find the gravitational field is
Gravitational constant G
We have to find the gravitational filed
Gravitational field is given by 
This will be the expression of gravitational field due to mass at a distance
