Answer:
The answer is 20727w
Explanation:
The formula is below;
P = d r^2 v^3 *efficiency
In the question, it is stated that the registration ignores efficiency so we are going to ignore efficiency in the equation and use it this way;
P = d r^2 * v^3
d =4.3, r = 1.59, v =n 12.4
Therefore, P = 4.3 X 1.59^2 X 12.4^3 = 20727W
The force on one end of the trough is 5.4 X 10⁵ N
<u>Explanation:</u>
The triangle is equilateral which means all the interior angles are 60° and the sides are 6m long.
According to the figure,
AI / 8 = sin (60) = √3/2
AI = 4√3
The depth of the water is AI = 4√3
The interval becomes, | 0 , 4√3|
w = 2JK
(the hydrostatic force acting on the strip is the product of the pressure and the area)
where.
ρ = 875 kg/m³
g = 9.8m/s²
d = depth ( d = y')
limit is 0 → 4√3
On solving the equation, we get the value of limit as 32√3
Therefore, the force on one end of the trough is 5.4 X 10⁵ N
Explanation:
Power output of the bulb:
0.021 × 60 W = 1.26 W
Energy produced by the bulb in 1 second:
E = Pt
E = (1.26 W) (1 s)
E = 1.26 J
Round as needed.
Answer:
Explanation:
An electric current is caused by the motion of electric charge. It is defined as the rate of flow of electric charges through any cross-section. If a net charge of Δq passes through any cross-section in Δt time, then electric current I has been established.Its unit is Ampere.
As it is time rate of change of charges, So
Answer:D) the charge on the positive plates.
Explanation:A capacitor is a passive Electric device that store Electric energy,capacitors are a little similar to batteries but they are not the same and they work in different ways.
A capacitor, contains two terminals which are connected to two metal plates separated by a non-conducting substance,the capacitance of a capacitor is the capacity of the capacitor to store Electric charge in it.
Of all the options only the charge on the positive plate will be different between both capacitors.
