B: formed by an active volcano
The relation between Power, Current and Voltage is given as:
P = V i
where P is Power in Watts,
V is Voltage in Volts,
and i is Current in Ampere.
We are given:
Power = 150 milliwatts = 0.15 Watts
(as 1 milliwatt = 0.001 Watts)
Voltage = 1.5 volts
and we need to find the current.
Hence using above equation:
P = V i
i = 
i = 
i= 0.1 Ampere
Answer:
The current used is 0.1 Ampere
Answer:
(i) The rotation speed must stay the same.
(ii) The rotation speed must increase.
(iii) The rotation speed must decrease.
Explanation:
According to Equation
10.10, the angular speed must therefore vary as the laser–lens system moves
radially along the disc. In a typical CD player, the constant speed of the surface at
the point of the laser–lens system is 1.3 m/s.
Consider the following array: Dim numbers(,) As Integer = {{1,2},{3,4},{4,5},{6,7},{8,9}} What row index value would be required
Kipish [7]
Answer:
The answer is "4"
Explanation:
The two-dimensional array or 2D array is the simplest form of the multilateral array. This array can be written as a table, in forms of rows and columns. It also known as an array chart.
declaration of two-dimensional array:
Dim a(,) As Integer = {{4, 0}, {0, 4}, {0, 4}, {4, 0}}//declaring of multi-dimensional array
In the given 2D array code, there we need 4-row index value, as we known array indexing always starts with 0, and in this array, 5 rows is equal to 0 to 4, that's why 4-row index value is the correct answer.
This is an artist who uses a printing method based on the principle that grease and water do not mix. The lithographer earlier used to draw on stone. This printing method allows for a full range of grayscale tone and finely articulated washes to be printed at once.
