While going 60 mph, how many feet will it take you to stop?

P waves are produced by all earthquakes. They are compression waves that form when rocks break due to pressure in the Earth. S waves are secondary waves that are also created during an earthquake. They travel at a slower speed than the p-waves.

S waves are the waves that come after the earthquake and P waves

Technician A says the counter gear is actually several gears machined out of a single piece of steel. Technician B says the coun

dexar [7]

Answer:

Option c. (Both Technician A and B are correct)

Explanation:

A transmission system consists of 3 shafts. The input shaft, the counter shaft, and the main shaft. The clutch gear always rotates with input shaft and is a crucial element of the input shaft.

The counter shaft is actually several gears machined out of a single piece of steel. The counter shaft may also be called counter gear or cluster gear. It is a secondary shaft that runs parallel to the mainshaft in a gearbox and is used to provide powers to machine components such as the drive axle.

The main gears (also called the speed gears) on main shaft (also known as the output shaft) are used to transfer rotation from counter shaft to the output shaft.

Hence in the light of above description, both technician A and B are correct.

Answer:

family They don't want them . There was a lady from there neighborhood can't bearer she said I can Take care of them . She was multi Millionaire she changed their names and she brought for them bed rooms ، bathroom and thire on toy's And a special clothing . they lived with her only 5 years then she said for the oldest daughter

step mom :mickey be careful with your siblings

Mikinzy : what will happen

Step mom: only I am telling you

After 2 weeks the step mother gaved the maid and told her.

Step mother: this is 3 millions for the kids and take care of them and don't tell them that I am traveling .

Maid : and if they asked me

step mother : she went to her family 5 months only .

Maid: but where you are going madame

Step mother: actually I am going to do a surgery in london

Maid : but why

Step mother: because I can't beCome

Pregnant

Maid: but you have mikinzy kareem and natalie

Step mother: it's not your problem so go away from my face

After 2 weeks mikinzy asked the maid where is my mother the maid told her everything mikinzy started to cry the maid went to her room

Maid mikinzy open the door I want to tell you something but I don't want natalie and kareem hear us

Mikinzy opened the door

Maid : I want to tell you something I love you and I hope to have only one daughter like You

Mikinzy : can you be my mother

Then the maid sell everything was at the castle and She said to mikinzy I will buy another castle to live there and buy our furniture mikinzy liked her idea after that mikinzy got bigger and studied medicine and became a doctor and her sister natalie studied special needs education and kareem became Engineer and they stayed with their maid actually there mom .

Aconstant current of 3 Afor 4 hours is required to charge an automotive battery. If the terminal voltage is V, where t is in hou

kirza4 [7]

Answer:

(a) 43.2 kC

(b) 0.012V kWh

(c) 0.108V cents

Explanation:

Given:

i = current flow = 3 A
t = time interval for which the current flow = $4\ h = 4\times 3600\ s = 14400\ s$
V = terminal voltage of the battery
R = rate of energy = 9 cents/kWh

Assume:

Q = charge transported as a result of charging
E = energy expended
C = cost of charging

Part (a):

We know that the charge flow rate is the electric current flow through a wire.

$\therefore i = \dfrac{Q}{t}\\\Rightarrow Q =it\\\Rightarrow Q = 3\times 14400\\\Rightarrow Q = 43200\ C\\\Rightarrow Q = 43.200\ kC\\$

Hence, 43.2 kC of charge is transported as a result of charging.

Part (b):

We know the electrical energy dissipated due to current flow across a voltage drop for a time interval is given by:

$E = Vit\\\Rightarrow E = V\times 3\times 4\\\Rightarrow E = 12V\ Wh\\\Rightarrow E = 0.012V\ kWh\\$

Hence, 0.012V kWh is expended in charging the battery.

Part (c):

We know that the energy cost is equal to the product of energy expended and the rate of energy.

$\therefore \textrm{Cost}=\textrm{Energy}\times \textrm{Rate}\\\Rightarrow C = ER\\\Rightarrow C = 0.012V\times 9\\\Rightarrow C =0.108V\ cents$

Hence, 0.108V cents is the charging cost of the battery.
