A negatively charged particle is moving to the right, directly above a wire having a current flowing to the right, as shown belo

w. In which direction is the magnetic force exerted on the particle?Answera. out of the pageb. into the pagec. upwardd. downwarde. The magnetic force is zero since the velocity is parallel to the current.

Answer:

Explanation:

As the current in the ire is towards right and the charge particle is above the wire, the direction of magnetic field due to the current carrying wire is perpendicularly outwards to the plane of paper. It is calculated by the Maxwell's right hand thumb rule. Now by using the Fleming's left hand rule, the direction of force is upwards.

A fluid flows along the x axis with a velocity given by V = ( x / t ) ˆ i , where x is in feet and t in seconds. (a) Plot the sp
umka21 [38]

Answer:

c)

 V_local = -x/t^2

 V_convec = x/t^2

d)

a =  V_local +  V_convec = 0

e) When a particle moves towards postive x direction its convective velocity increases, but at the same time the local velocity deacreases (at the same rate) when time increases

Explanation:

Hi!

You can see plots for a) and b) attached on this document

c)

The local acceleration is just teh aprtial derivative of the velocity with respect to t:

\frac{dV}{dt} = \frac{d}{dt} \frac{x}{t}=- \frac{x}{t^2}

And the convective acceleration is given by the product of the velocity times the gradient of the velocity, that is:

\vec{v} \cdot \nabla \vec{v} = v ( \frac{dv}{dx} ) =\frac{x}{t} \frac{1}{t} = \frac{x}{t^2}

d)

Since the acceleration of any fluid particle is the sum of the local and convective accelerations, we can easily see that it is equal to zero, since they are equal but with opposit sign

e)

This is because of teh particular form of the velocity. A particle will move towards areas of higher velocities (convectice acceleration), but as time increases,  the velocity is also decreasing (local acceleration), and the sum of these quantities adds up to zero

Be sure you understand why a pendulum in equilibrium hanging in a car that is accelerating forward tilts backward, and then cons
Gnesinka [82]

Answer:

A helium filled balloon floats forwards in a accelerating car because of the pressure difference between the front and the back of the car. When the car is accelerating, the air moves relitive to the car and the consequence is that the pressure in the back is slightly higher than in the front; which results in net force in forward direction.

What is the difference between obtaining knowledge from a controlled experiment versus other forms of scientific investigation?
solong [7]

Answer:

Any scientific investigation in its simplest form involves collecting information, while a controlled experiment is a tightly controlled investigation that tests a hypothesis.

Explanation:

All the scientific investigations start with a particular question. The question decides what type of investigation should research take. A controlled experiment is an investigation which allows a particular variable to change and all other variable controlled to remain constant to see the effect on dependent variable to test a particular hypothesis while other types of investigations are used to increase the knowledge or information about the particular research subject.
