Which statement describes a difference between insulators and conductors?(1 point)
Insulators have high conductivity, while conductors have low conductivity.
Insulators can transmit electric current, while conductors cannot.
Insulators are made of metallic materials, while conductors are not.
Insulators have high resistance, while conductors have low resistance.
Answer:
The "Insulators have high resistance, while conducters have low resistance".
The difference between insulators and conductors is insulators have high resistance, while conductors have low resistance.
What is insulator?An insulator is a material that does not allow easy passage of electric current through it. In other words, these materials have high resistance to the flow of current.
What is conductor?A conductor is a material that allows easy passage of electric current through it. In other words, these materials have low resistance to the flow of current.
Thus, the difference between insulators and conductors is insulators have high resistance, while conductors have low resistance.

Can an object have both kinetic energy and gravitational potential energy? Explain.
Answer:
Yes
Explanation:
An object can be moving (have kinetic energy) and be elevated above the ground at the same time (and also have potential energy).
Yes an object can be moving have kinetic energy and be elevated above the ground at the same time and also have potential energy.
What is energy?Energy is the ability or capability to do tasks, such as the ability to move an item (of a certain mass) by exerting force. Energy can exist in many different forms, including electrical, mechanical, chemical, thermal, or nuclear, and it can change its form.
The energy an object has as a result of motion is known as kinetic energy. A force must be applied to an object in order to accelerate it. We must put in effort in order to apply a force. Following work, energy is transmitted to the item, which causes it to move at a new, constant speed. An object can store energy as the result of its position is potential energy.
An object can be moving have kinetic energy and be elevated above the ground at the same time and also have potential energy.

The diagram below shows a 1.0 x 105newton truck at rest on a hill that makes an angle of 8.0° with the
horizontal. What is the component of the truck's weight parallel to the hill? (hint: the weight was already
calculated, also you can use the work area to help you solve this.]
Answer:
[tex]it \: is \: mg \sin(8.0 \degree) \\ = 1.0 \times 10 {}^{5} \times \sin(8.0 \degree) \\ = 9.9 \times 10 {}^{4} newtons[/tex]
The component of the truck's weight parallel to the hill is 13,917.31 N.
The given parameters:
Weight of the truck, W = 1.0 x 10⁵ NInclination of the hill, θ = 8⁰The component of the truck's weight parallel to the hill is calculated as follows;
[tex]W_x = mg \times sin(\theta)\\\\W_x = W \times sin(\theta)\\\\W_x = 1\times 10^5 \times sin(8)\\\\W_x = 13,917.31 \ N[/tex]
Thus, the component of the truck's weight parallel to the hill is 13,917.31 N.

Q: Is the direction important when calculating speed? Explain.
Answer:
Depends.
Explanation:
Whether the object is going left or right, the speed will stay the same until friction eventually stops it. However, if, for example, we're talking about an object going straight before veering right, then yes, speed does matter. An object will normally have to speed up or slow down momentarily when changing direction to keep itself sustained on the ground.
So, honestly? It really depends on what we're talking about!

A skier waits at the top of a 11.7m hill. He then skis down the slope at an angle of 27 degrees above horizontal. What will his velocity be at the bottom of the hill? Show work
Answer:
v = 3.89 m / s
Explanation:
For this exercise let's use the concept of conservation of mechanical energy
starting point. In the highest part of the mountain
Em₀ = U = m g h
final point. In the lower part
Em_f = K = ½ m v²
how energy is conserved
Em₀ = Em_f
mgh = ½ m v²
v = [tex]\sqrt{ 2gh}[/tex]
let's use trigonometry to find the height
sin θ = h / L
h = L sin θ
we substitute
v = [tex]\sqrt{ 2g L \ sin tea}[/tex]
let's calculate
v = [tex]\sqrt{2 \ 9.8 \ 1.7 \ sin 27}[/tex]
v = 3.89 m / s
How does the Coriolis effect influence the direction of the Trade Winds in the Northern Hemisphere? Does it have the same effect in the Southern Hemisphere?
Answer:
Part A
Coriolis effect is used to describe how objects which are not fixed to the ground are deflected as they travel over long distances due to the rotation of the Earth relative to the 'linear' motion of the objects
Due to the Coriolis effect the wind flowing towards the Equator from high pressure belts in the subtropical regions in both the Northern and Southern Hemispheres are deflected towards the western direction because the Earth rotates on its axis towards the east
Part B
In the Northern Hemispheres, the winds are known as northeasterly trade winds and in the Southern Hemisphere, they are known as the southeasterly trade wind. Therefore, Coriolis effect has the same effect on the direction of the Trade Winds in the Southern Hemisphere as it does in the Northern Hemisphere

Singly charged uranium-238 ions are accelerated through a potential difference of 2.20 kV and enter a uniform magnetic field of 1.90 T directed perpendicular to their velocities. Determine the radius of their circular path.
Answer:
r = 0.0548 m
Explanation:
Given that,
Singly charged uranium-238 ions are accelerated through a potential difference of 2.20 kV and enter a uniform magnetic field of 1.90 T directed perpendicular to their velocities.
We need to find the radius of their circular path. The formula for the radius of path is given by :
[tex]r=\dfrac{1}{B}\sqrt{\dfrac{2mV}{q}}[/tex]
m is mass of Singly charged uranium-238 ion, [tex]m=3.95\times 10^{-25}\ kg[/tex]
q is charge
So,
[tex]r=\dfrac{1}{1.9}\times \sqrt{\dfrac{2\times 3.95\times 10^{-25}\times 2.2\times 10^3}{1.6\times 10^{-19}}}\\\\r=0.0548\ m[/tex]
So, the radius of their circular path is equal to 0.0548 m.
