A cotton garment cannot keep us warm in winter as a woolen sweater can. Give
reason.
Answer:
Cotton clothes are thin and do not have space in which air can be trapped. Thus, cotton clothes do not prevent heat coming out of our body. Woollen clothes keep us warm during winter because wool is a poor conductor of heat and it has air trapped in between the fibres.
Explanation:
Answer:
woolen clothes in winter because woolen clothes gives us warmth. ... We should wear light colored clothes in summer because light coloured clothes keeps us cool as they insulate the heat. And cotton clothes makes us comfortable in summers and cotton clothes absorb the sweat which we get mostly in summers

1.Automatic out
2.Force out
3.Tag up
4.Ground out
Answer:4
Explanation:
A thin spherical shell with radius R1 = 4.00 cm is concentric with a larger thin spherical shell with radius R2 = 6.00 cm . Both shells are made of insulating material. The smaller shell has charge q1=+6.00nC distributed uniformly over its surface, and the larger shell has charge q2=−9.00nC distributed uniformly over its surface. Take the electric potential to be zero at an infinite distance from both shells.
Answer:
The right response will be "450 volts".
Explanation:
The given values are:
R1 = 4.00 cm
R2 = 6.00 cm
q1 = +6.00 nC
q2 = −9.00 nC
As we know,
The potential difference between the two shell's difference will be:
⇒ [tex]\Delta V=K[(\frac{q1}{R1}+\frac{q2}{R2})-(\frac{q1}{R1} +(\frac{q2}{R2}))][/tex]
[tex]=K[\frac{q1}{R2}-\frac{q1}{R1} ][/tex]
On substituting the values, we get
[tex]=(9\times 10^9)[\frac{6\times 10^{-9}}{0.04}-\frac{6\times 10^{-9}}{0.06}][/tex]
Δ [tex]=450 \ volts[/tex]

What evidence shows galaxies are moving away from us?
speed
blue shift
red shift
changes in light
Answer:
Redshift and blueshift describe how light shifts toward shorter or longer wavelengths as objects in space (such as stars or galaxies) move closer or farther away from us. The concept is key to charting the universe's expansion.
Visible light is a spectrum of colors, which is clear to anyone who has looked at a rainbow. When an object moves away from us, the light is shifted to the red end of the spectrum, as its wavelengths get longer. If an object moves closer, the light moves to the blue end of the spectrum, as its wavelengths get shorter hope this helps.

What are assessments?The phrase "assessment" refers to the broad range of techniques or instruments that educators employ to assess, gauge, and record pupils' academic preparedness, learning progress, skill development, or educational requirements.
Education professionals use a wide range of assessment tools and methods to gauge everything from a four-year-readiness old's for kindergarten to a twelfth-grade student's comprehension of advanced physics.
Despite the fact that assessments are frequently mistaken for traditional tests, particularly the standardized tests created by testing companies and given to large populations of students, educators use a variety of assessment tools and methods.
Therefore, A. They can provide an accurate picture of someone’s personality and C. They can be used to target employee training, E. They may lead to lower turnover rates.

Since kinetic energy depends on mass and speed, will a 300-pound baseball player hit the ball farther than a 100-pound baseball player? EXPLAIN
Assume the following conditions in this scenario:
1. The bat is identical in mass and weight for both players
2. both players swing the bat with the same velocity
3. The weather conditions are identical for both players (wind, climate etc..)
4. both players meet the ball squarly so as to hit the ball in the same place for the best outcome
It's definitely a Physics question !
Here's how I would look at it:
The player doesn't hit the ball. The bat does.
You said that the two bats are identical, and both players swing the bat with the same speed.
So at the point where the bat meets the ball, the conditions are the same both times.
The ball can't tell the difference.
Its history will unfold identically after both hits.

According to the kinetic theory, all matter is composed of _______.
Answer:
According to the kinetic theory, all matter is composed of _______.
Explanation:
The Kinetic Theory of Matter states that matter is composed of a large number of small particles, individual atoms or molecules, that are in constant motion. Matter is made up of particles that are constantly moving. All particles have energy, but the energy depending on the temperature of which matter is in.
According to the kinetic theory, all matter is composed of large number of identical small molecules.
What is kinetic theory of gases?
A lot of the fundamental ideas of thermodynamics were established with the help of the kinetic theory of gases, a straightforward yet historically significant classical model of the thermodynamic behavior of gases.
According to the model, a gas is made up of numerous identical submicroscopic particles (atoms or molecules) that are all moving rapidly and randomly.
It is considered that they are substantially smaller in size than the particle spacing on average. Random elastic collisions between the particles and with the container's walls occur between the particles. The simplest form of the model only takes into account the interactions within the ideal gas.

Explanation:
how is the friction force produced
Explanation:
Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.

Х
D)
46.0 N
Answer:
The answer is 46.0089 N of weight
Explanation:
The answer is in the question
F=mg
reverse the question, mg=F
Plug in the values of mass (4.69) and gravity (9.81)
4.69(9.81)=F
F = 46.0089 (or D)

Explanation:
A bowling ball rolls off the edge of a flat roof at a velocity of 16 m/s. What is the actual speed of the ball one second later?
Answer:
The horizontal velocity is constant at 16 m/s.
After 1 sec since v = a t then 9.8 m/s^2 * 1 sec = 9.8 m/s for the vertical velocity
V = (Vx^2 + Vy^2)^1/2 = (16^2 + 9.8^2)^1/2 = 18.8 m/s

Answer:
Take a Buzzfeed quiz
Explanation:
I doubt finding your spirit animal is easy, so you must consult the infamous website known for random personality quizes, Buzzfeed.
I'm sure there will be many quizes focused on the exploration of spirit animals, and finding yours with accuracy is something Buzzfeed takes pride in, (despite the fact that this is a comercial buisness with the only intent of making money off of your personality quiz exploits) so your spirit animal should be found with ease.
If Buzzfeed turns out to be unsucsessful, I recomend just searching up your question online to find countless other resources dedicated to your spirit animal journey.
You could also consult your local witch to see if they know anything about spirit animals.
Answer:
i will tell you how to do it because i've done it before
Explanation:
So to find your spirit animal you don't choose it. It chooses you. To find yours it can be in your dreams, daydreams. Look into your concious. In your dreams look at the animals to see if there is anything unusal about them that is out of the ordinary. It will show itself to you in ways you might not realize. If you do see an animal out of the ordinary, inspect it, try asking it something, because if it shows itself to you that means it is willing to guide you. Thats what your spirit animal is for.
