Answer from: hartzpeyton136

1. B. Increase

2. A. Decrease

Explanation:

To understand this issue, we need to put some values and using the ohm's law we can corroborate the two situations.

Ohm's law:

V = I*R\\where:\\I = current[A] ampers\\R = resistance [ohms]\\V = voltage [volts]\\

Now for the voltage we will use V = 110 [V], for resistance R = 10 [ohms]

Replacing the values we have:

I = \frac{V}{R} \\\\I = \frac{110}{10}\\I= 11 [amp]

Now let's double the voltage 220 [V]:

I = \frac{220}{10} \\I = 22 [amp]\\

Therefore the current will be increased.

Let's do the same for the resistance if originally we have R = 10 [ohms]

I = \frac{V}{R}\\I = \frac{110}{10} \\I = 11 [amp]\\

Now let's double the resistance 20 [ohms]:

I=\frac{110}{20}\\I = 5.5 [amp]

Therefore the current will be decreased.

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.

Antireflective coatings on solar cells are often made by applying a thin film of silicon nitride (sinx), which has an index of refractive of 1.2, on the top of the silicon solar cell, which has a refractive index of about 3.5. however, the sun emits radiation of various wavelengths which the solar cell absorbs, and the antireflective coating can only absolutely minimize the reflection of one of these wavelengths. the coating thickness is chosen to reduce the reflection of green/yellow light (e = 2.2 ev), which is the most intense color in the solar spectrum (shown below). which of the following coatings would minimize reflection of green/yellow light? the answer is 820 nm how? what is the angular width of the central maximum of an electron traveling at 2 x 108 m/s going through a single slit of width 1 mm.

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.
