Answer:
The y-component of the electric force on this charge is 
Explanation:
<u>Given:</u>
- Electric field in the region,
- Charge placed into the region,
where, 
are the unit vectors along the positive x and y axes respectively.
The electric field at a point is defined as the electrostatic force experienced per unit positive test charge, placed at that point, such that,
Thus, the y-component of the electric force on this charge is
The time it takes for a point to reach 0 displacement from maximum displacement is
of a cycle. Thus, one period (
) will take
.
The frequency is simply
.
The speed is given by:
Answer;
= 4.49 g/cm³
Explanation;
Density = Mass / Volume
mass = 1.41 kg,
volume = 0.314 L
but; 1 kg = 1000 g and 1 L = 1000 mL
Thus;
Density = 1.41 kg/0.314L
Density = 4.49 kg/L (1000g/ 1kg)(1L/1000cm^3)
Density = 4.49 g/cm^3
Answer:
I need an image, but if you're talking about Potential and Kinetic energy, I will determine for you:
Explanation:
Potential Energy: stored energy that depends upon the relative position of various parts of a system.
Kinetic Energy: the form of energy that an object or a particle has by reason of its motion.
Therefore, if the skier is on top of the mountain, they would have potential energy since their energy from the ground to the top of the surface is stored. But, if the skier is in motion/mid-air from the top of a mountain, their energy is kinetic (in motion) because their stored energy (potential) is released as they step off of the surface.
Well, wind can change landforms by storms, and hurricains, or other things that contain air...
~~~~~~~~~~~~~
Like, over a period of time... Wind can make landforms decrease in size, by weathering.

Hope this helps! :)
