Answer:

Answer is B. counting the number of heartbeats for 6 seconds. :)

Explanation:

To quote the text, "You must make a fist with one hand before using the index and middle fingers of your other hand to press down on the artery to find it. Once you have found the artery, locate your pulse and count how many heartbeats you can feel for 10 seconds. Multiply the number by 6 to get the approximate number of heartbeats in 60 seconds, or bpm."

A 40.0 kg wagon is towed up a hill inclined at 18.5 degrees with respect to the horizontal. The tow rope is parallel to the incl

sp2606 [1]

Answer:

7.9m/s

Explanation:

We are given that

Mass of wagon=40 kg

$\theta=18.5^{\circ}$

Tension= $140 N$

Initial velocity of wagon= $u=0$

Displacement=s=80 m

Net force applied on wagon= $F=T-mgsin\theta=140-40(9.8)sin18.5=15.7 N$

By using $g=9.8m/s^2$

$a=\frac{F}{a}=\frac{15.7}{40}=0.39m/s^2$

We know that

$v^2-u^2=2as$

Using the formula

$v^2=2\times 0.39\times 80$

$v=\sqrt{2\times 0.39\times 80}=7.9m/s$

What is the best description of the end result of chemical bonding for most

forsale [732]

A. Getting a full set of valence electrons

Explanation:

The best description of the end result of chemical bonding for most atoms is the getting of a full set of valence electrons.

Atoms reacts with one another in order to complete valence electronic shell.

The valence electron shell is the outermost energy level of an atom.
It is from this energy level that electrons are lost or gained to form bonds.
All atoms wants to be like the noble gases whose valence electronic shell is completely filled up
This is the crux of chemical bonding
The attraction that is produced from the interaction leads to bond formation

Un casquillo de cobre de 8 kilogramos tiene que calentarse de 25 a 140 grados Celsius con el fin de expandirlo pata que se ajust

uranmaximum [27]

Answer:

354200J

Explanation:

Given parameters:

Mass of copper bushing = 8kg

Initial temperature = 25°C

Final temperature = 140°C

Unknown:

Quantity of heat required to heat this mass = ?

Solution:

The amount of heat required to heat mass from one temperature to another is given by;

H = m c Δt

where m is the mass

c is the specific heat

Δt is the change in temperature

C is a constant and for copper, its value is 385J/kg°C

Input the parameters;

H = 8 x 385 x (140 - 25) = 354200J
