Answer:
The force F is created by the reaction of the Earth to the thrust of the rods, whereby the thrust is created by a force of action and reaction.
Explanation:
To answer this question, let's write Newton's second law of the two axes
Y Axis
Fy + N - W = 0
Fy + N = W
X axis
Fx - fr = 0
Fx = fr
The force F is created by the reaction of the Earth to the thrust of the rods, whereby the thrust is created by a force of action and reaction.
The direction of this force is along the length of the rods that are in an Angle, where the x and y components of the force come from
In general this force is small because the rubbing of the skis is small
Answer:
Yes
Explanation:
Kinetic energy is K.E1/2mv2 so that means it is directly proportional to mass and velocity.
Can you include an image of the object and it’s dimensions?
Answer:
V = IR
Explanation:
Voltage is denoted by V, current is denoted by I and resistance is denoted by R. Voltage is the difference of electric potential between two points. Current is the measure of the rate of flow of electric charge. Resistance is a measure how a device reduces the current flow through itself.
The three properties are related to each other as per the Ohm's law which states that voltage and current are directly proportional to each other, it can be denoted as
Voltage (V) = Current(I) X Resistance(R).

1. Single dental x-rays: 
The energy of the photon is

Using the conversion factor

we can convert it into Joules:

The relationship between photon energy and wavelength is

where
is the Planck constant
is the speed of light
E is the energy
Substituting into the formula, we find

2. Microtomography: 
The energy of these photons is 2.5 times greater, so

And by applying the same formula used at point 1, we find the corresponding wavelength:
