What is one key physical difference between transition metals and poor metals?

Answers

Answer 1

Answer:

HARDNESS

Explanation:

One key physical difference between transition metals and poor metals is their "" Hardness"" which is

the ability of a material to resist deformation. The test for hardness can be determined by a standard test which is the measurement of surface resistance to indentation. hardness tests are defined the shape and also type of indent.

The poor metals are also referred to as post transition metals. They are elements that are found at the right of the transition metals,they are located in the p-block,Their properties is as a result of their low melting and boiling point compare to other metals.They have high electronegativity and conductivity but softer texture compare to other metals.They are very soft more than the transition metals, but they cannot be cannot be classified as metalloids.

Poor metals includes elements in the periodic table such as; aluminium, gallium, indium, thallium, tin, lead, bismuth, and polonium.

When you approach a light source, the wavelength of emitted light appears _____.a. shorter
b. the same
c. longer

Answers

When you approach a light source, or when the light source
approaches you, the wavelength of the light you see is shorter
than the wavelength of the light that's actually emitted by the source.

Similarly, when you approach a sound source, or when the sound
source approaches you, the wavelength of the sound you hear is
shorter than the wavelength of the sound that's actually emitted by
the source.

Answer:

A. shorter

1. Sometimes in very cold places water pipes burst. Give reason why.

Answers

Water is the only known substance that gets BIGGER when it freezes.
That's why ice cubes float in liquid water, and the reason that pipes
or cans of soda spring leaks when the liquid water that they're full of
freezes and gets bigger.

When is very cold, water freezes in pipes expanding and turns into ice. This frozen water is expanding and bursting pipe.

SPEAR is a storage ring at the Stanford Linear Accelerator which has a circulating beam of electrons that are moving at nearly the speed of light (2.998 108 m/s). If a similar ring is about 92.0 m in diameter and has a 0.40 A beam, how many electrons are in the beam

Answers

Answer:

$2.4* 10^(12)$

Explanation:

We are given that

Speed of light,v= $2.998* 10^8 m/s$

Diameter of ring,d=92 m

Radius,r= $(d)/(2)=(92)/(2)=46 m$

Current, I=0.40 A

We have to find the number of electrons in the beam.

We know that

Current,I= $(q)/(t)$

Where q= ne

$e=1.6* 10^(-19) C$

Using the formula

$0.40=(1.6* 10^(-19)n)/((2\pi r)/(v))$

$0.40=(1.6* 10^(-19)n* v)/(2\pi r)$

$0.40=(1.6* 10^(-19)n* 2.998* 10^8)/(2\pi* 46)$

$n=(0.40* 2\pi* 46)/(1.6* 10^(-19)* 2.998* 10^8)=2.4* 10^(12)$

Answers

Answer:

It is easier

Explanation:

when riding a bicycle on a straight path you need to do more of the control and paddling to keep the bicycle on right motion, but round a bend, the wheels and tyres are already aligned to the bending path and you need not to do much work by controlling the wheels

Think about multiplying each speed by a factor to calculate kinetic energy at that speed.Is there a common factor that works for every speed? If so, what’s this factor?

Answers

Answer:

To calculate kinetic energy, you use the formula KE = 0.5 * m * v^2, where "m" is the mass and "v" is the speed. There isn't a common factor that works for every speed; the factor you use is 0.5. This formula is derived from the principles of classical mechanics and doesn't change with speed; it's a fundamental equation for calculating kinetic energy.
