Answer: Hope This Helps!

Explanation:

1: Newton’s first law of motion can explain how a magician pulls a tablecloth from underneath the dishes. A negligible horizontal force is applied during the process. As per Newton’s first law of motion, the dishes and glasses remain in their state of motion (rest); as a result, they remain undisturbed.

2: Newton's First Law of Motion is defined as "An object at rest and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force."In soccer, when the soccer ball is in the soccer field and it is not moving, that means that it is at rest and there is no force acting upon it. When there is a person that is ready to play soccer and wants to kick the ball and play, then the unbalanced force would be the power from the person's foot.

3: Newtons third law can explain, as the cannonball is pushed forwards by the expanding high-pressure gases created by the exploding gunpowder, it pushes back on these gases. The gases push back on the cannon itself, causing it to roll backwards. Alternative answer: the cannon pushes forward on the cannonball. the reaction force is the cannonball pushing backwards on the cannon.

marishachu [46]
Newton's second law of motion states the following:

F=ma

In which F is the force, m is the mass, and a is the acceleration of the object.

So, the answer is B.

7. A double-slit experiment uses coherent light of wavelength 633 nm with a slit separation of 0.100 mm and a screen placed 2.0
Illusion [34]

Answer:

The distance between first-order and second-order bright fringes is 12.66mm.

Explanation:

The physicist Thomas Young establishes through its double slit experiment a relationship between the interference (constructive or destructive) of a wave, the separation between the slits, the distance between the two slits to the screen and the wavelength.

\Lambda x = L\frac{\lambda}{d}  (1)

Where \Lambda x is the distance between two adjacent maxima, L is the distance of the screen from the slits, \lambda is the wavelength and d is the separation between the slits.  

The values for this particular case are:

L = 2.0m

\lambda = 633nm

d = 0.100mm

Notice that is necessary to express L and \lambda in units of milimeters.

L = 2.0m \cdot \frac{1000mm}{1m} ⇒ 2000mm

\lambda = 633nm \cdot \frac{1mm}{1x10^{6}nm} ⇒ 6.33x10^{-4}mm

Finally, equation 1 can be used:

\Lambda x = (2000mm)\frac{(6.33x10^{-4}mm)}{(0.100mm)}

\Lambda x = 12.66mm

Hence, the distance between first-order and second-order bright fringes is 12.66mm.
