Analyze how friction can be both a positive and negative aspect In our every day lives

Answers

Answer 1

Answer: Friction-Now a positive part of friction could be that it helps us from falling while we move about,friction also creates energy
A negative part could be that it produces heat that could damage different forms of machinery and also causes tear in the machinery

What is the wavelength of a 147-g baseball traveling at 91.0 mph?

Answers

The formula to determine the wavelength is, De-Broglie wavelength formula:

$\lambda =(h)/(mv)$ -(1)

where, $\lambda$ is wavelength, m is mass, v is velocity and h is Planck's constant = $6.63* 10^(-34) Js$ = $6.63* 10^(-34) kgm^(2)s^(-1)$

mass, m = 147 g (given)

Since, 1 g = 0.001 kg

So, 147 g = 0.147 kg

v = 91.0 mph (given)

Converting mph to mps:

Since, $1 mph = (1.609* 10^(3) ms^(-1))/(60* 60)$

So, $90 mph = (91* 1.609* 10^(3) ms^(-1))/(60* 60)$ = $40.67 ms^(-1)$

Substituting the values in formula 1:

$\lambda =(6.63* 10^(-34) kgm^(2)s^(-1))/(0.147 kg* 40.67 ms^(-1))$

$\lambda =1.11* 10^(-34) m$

Hence, the wavelength wavelength of a 147-g baseball traveling at 91.0 mph is

$1.11* 10^(-34) m$ .

Explanation:

The concentration (M) of a methanol solution produced when 0.400 L of a 2.00 M solution was diluted to 0.800 L is __________ M.

Answers

Answer: 1.00 M

Explanation: The problem can be solved using the formula of dilution which is the product of Molarity and volume M1V1= M2V2.

Derive for M2, so the formula will be M2 = M1V1 / M2

M2 = 2.00 M ( 0.400 L ) / 0.800 L

= 1.00 M

Answer:

1.00 M

Help me!!! Several small craters lie in the floor and on the walls of crater 2. Which is older,crater 2 or the smaller craters inside it?

Answers

Well, think of it this way. If you put a big paper circle on the ground, and then you put smaller circles on top of the big circle, which one would have been there longer? The big circle, of course. So the same logic applies here: if the smaller craters had been older than the big crater, then when the big crater was formed, the smaller ones would've been buried. Therefore, crater 2 is older than the smaller craters inside it.
Hope that helped! =)
