Answer:
Vectors have both magnitude and direction
Explanation:
Vectors show how strong the force in because the bigger the arrow, the stronger the force. Also, it obviously shows direction because its an arrow.
When light hits the boundary between two different materials, it can undergo both reflection and refraction.
Reflection is the change in the direction of the
wave that strikes the boundary between two materials.<span> It involves a change in the direction of waves when they clash with an obstacle.
Refraction involves the change in the direction of waves as they move from one medium to </span><span><span>another followed</span></span><span> by a change in speed and wavelength (this second medium should have different permitivity for the light to change its initial properties.)</span>
Answer: t-trees?
i couldn't find anything on this topic but the only thing i could think of was trees, maybe if you go to a history website you can find a answer there :)
hope i helped a little :)
Answer:
the answer is B
Explanation: this was actually an ap exam question a few years back. the reason for answer B is that the only force being applied to the kitten is the force of gravity after being pushed.
Answer:
The value of developed electric force is 
Solution:
As per the question:
Mass of the droplet = 1.8 mg = 
Charge on droplet, Q = 
Distance between the 2 droplets, D = 0.40 cm = 0.004 m
Now, the Electrostatic force given by Coulomb:




The magnitude of force is too low to be noticed.
