A one dimensional array data is declared as follows: char data[4]; the base address is 2222 and each value takes up one location
andrezito [222]

The correct answer for the address of the fourth element will be 2225.

The fourth element will be data -.

So if the data[0] element starts at 2222, and each char element takes 1 byte, then

data[0] starts at 2222

data[1] starts at 2223

data[2] starts at 2224

data[3] starts at 2225

Answer: 2225

A linear data structure that collects elements of the same data type and stores them in contiguous and adjacent memory locations is known as an array. Arrays use an index system that ranges from 0 to (n-1), where n is the array's size.

The array data type is a compound data type represented in the database dictionary by the number 8. Arrays are collections of elements of the same data type that are accessed via an index (attribute) number. The terms array, list, vector, and sequence are all synonymous

If a 60 W light bulb and a 75 W light bulb operate from 150 V source, which bulb has a greater current in it?
Monica [59]

Answer:

Since it us the resistance that causes the power output, it might be intuitive to think that more resistance produces more power but as P=I^2 * R one actually needs high current and low resistqnce. That means 75 W has lower resistance and higher current.

Now you may think that making the resistance very low, one gets the most power. Not so, as the circuit has wires, power source etc. All the have their resistance. In theory one gets the maximum power over a resistor when the resistor is half of the total resistance of the circuit. This in practice would be inefficient as one would lose half of the total power elsewhere. In practice circuits have fuses that limit the current and one gets the maximum power at the current the fuse is rated to. So if there is 20 A fuse, the maximum power is 2400 W and the corresponding resistance 6 ohm.

A small metal sphere has a mass of 0.14 g and a charge of -26.0 nC. It is 10.0 cm directly above an identical sphere that has th
Tju [1.3M]

Answer:

A)

608.4\times10^{-6} N

B)

5.5 ms^{-2}

Explanation:

A)

q = magnitude of charge on each sphere = 26\times10^{-9} C

r = Distance between the two spheres = 10 cm = 0.10 m

F = magnitude of force between the two spheres

Using Coulomb's law, magnitude of the force between two charged sphere

F = \frac{kq^{2}}{r^{2}}\\F = \frac{(9\times10^{9})(26\times10^{-9})^{2}}{(0.1)^{2}}\\F = 608.4\times10^{-6} N

B)

m = mass of the sphere = 0.14\times10^{-3} kg

F_{g} = Force of gravity in down direction = mg = (0.14\times10^{-3})(9.8) = 1.372\times10^{-3} N

F = Electrostatic force of repulsion in upward direction = 608.4\times10^{-6} N

a = acceleration of the sphere

Force equation for the motion of the sphere is given as

F_{g} - F = ma \\1.372\times10^{-3} - 608.4\times10^{-6} = (0.14\times10^{-3}) a\\a = 5.5 ms^{-2}

Since this object is traveling at terminal velocity, what must be the value of Fd? (HINT: how to the lengths of both arrows comp
Juli2301 [7.4K]

The magnitude of the air drag when the object is traveling at terminal velocity is C. 850 Newtons

Explanation:

There are only two forces acting on the object here:

- The force of gravity, of magnitude F_g = 850 N, acting downward

- The air drag, F_d, acting upward

Therefore, the equation of motion for the object is

F_g - F_d = ma

where m is the mass of the object and a its acceleration.

The object in this problem is traveling at terminal velocity: this means that the acceleration is zero, so

a = 0

Therefore the equation becomes

F_d = F_g

which means that the magnitude of the air resistance is equal to the magnitude of the force of gravity:

F_d = 850 N
