Answer:
The number of electrons is 
(D) is correct option.
Explanation:
Given that,
Battery capacity = 750 mA-h
Time t= 8 hours
Time t'=3 hours
We need to calculate the battery capacity
We need to calculate the number of electrons in 1 C Li
Using formula for number of electron
We need to calculate the number of electron in 2700 C
The total number of electrons battery can deliver in 8 hours
We need to calculate the number of electron in 3 hours
Using formula of number of electrons
Put the value into the formula
Hence, The number of electrons is
Mar 28, 2011 · The Hoover Dam generates
electricity using hydropower. Hydropower is the power generated by
moving water. Dams are often built on a large river, so the water falls
down from the top of the dam. At the bottom of the dam, the water
rotates a large turbine
Hope this helps :p
Answer:
at the highest point of the path the acceleration of ball is same as acceleration due to gravity
Explanation:
At the highest point of the path of the ball the speed of the ball becomes zero as the acceleration due to gravity will decelerate the motion of ball due to which the speed of ball will keep on decreasing and finally it comes to rest
So here we will say that at the highest point of the path the speed of the ball comes to zero
now by the force diagram we can say that net force on the ball due to gravity is given by
now the acceleration of ball is given as
so at the highest point of the path the acceleration of ball is same as acceleration due to gravity
Answer:
The density of the mercury is 13.2 g/cm³
Explanation:
Density is a measurement that compares the amount of matter an object
has to its volume
Density is equal to mass divided by volume
We need to find the density of mercury if 500 cm³ has a mass of
6.60 kg in g/cm
We must to change The kilogram to grams
The mass of mercury is 6.60 kilograms
1 kilogram = 1000 grams
6.60 kilograms = 6.60 × 1000 = 6600 grams
Density = mass ÷ volume
The volume of the mercury is 500 cm³
The density = 6600 ÷ 500
The density = 13.2 g/cm³
<em>The density of the mercury is 13.2 g/cm³ </em>
Answer:
D. Speed up the assembly line transfer mechanism
Explanation:
All of the options are logic and very intelligent ways to reduce the longest task time, but if you just speed up the assembly line transfer you will end up with two possible outcomes, frustrated workers cause they always have to be rushing up to finish their task and thus a lower quality in the product you are producing, or that the workers on that specific part of the assembly line definetely can´t perform the task and endu up not doing their job and you end up with incomplete products.
