The magnitude of the electric current is inversely proportional to the _____ of the circuits in R2D2.

nika2105 [10]

According to Ohm's Law, the voltage is equal to the current multiplied by resistance. Presenting the law in equation form:

V = IR

This law still applies in an R2-D2 droid circuit. Rearranging the equation:

I = V/R

Hence, the current is inversely proportional to the resistance.

We wish to obtain a equal sized inverted image of a candel flame on a screen kept at a distance of 4m from the candle flame a) n

soldier1979 [14.2K]

A) To obtain an inverted image of an object of same size a convex lens is used.

In this question we have given

Distance between candle flame and screen=4

it means distance between candle flame and lens +distance between lens and screen =4m

u+v= 4m

u= v

therefore, 2u= 4m

or, u=-2m ( u is taken negative because it lies on left side of the lens)

and v=2m

we have to find the focal length of convex lens

$\frac{1}{f} = \frac{1}{v} - \frac{1}{u}$ $\frac{1}{f} = \frac{1}{2} - ( - \frac{1}{2} ) \\ \frac{1}{f} = \frac{1}{1}\\ f = 1m$

Hence, Focal length of the lens is 1m

and lens should be placed at a distance of 2m from the flame

What would be the necessary to use the accelerometer to measure in the units of m/s2

Nookie1986 [14]

M/s2 is the SI of an acceleration.

a couple of things that are necessary to measure this :
- use the timing resources to measure the duty cycle
- performing a computationally intensive division operation

A car with a mass of 600 kg is traveling at a velocity of 10 m/s. How much kinetic energy does it have? The car has J of kinetic

konstantin123 [22]

The kinetic energy of an object is given by:
$K= \frac{1}{2}mv^2$
where m is the mass of the object and v its velocity.

The car in this problem has a mass of m=600 kg and a velocity of v=10 m/s, therefore if we put these numbers into the equation, we find the kinetic energy of the car:
$K= \frac{1}{2}mv^2= \frac{1}{2}(600 kg)(10 m/s)^2=30000 J$

50. a kangaroo can jump over an object 2.50 m high. (a) calculate its vertical speed when it leaves the ground. (b) how long is

Ira Lisetskai [31]

Answer:

The easiest way to do this is to realize that the time to fall is the same as the rise time (conservation of energy can easily verify this)

S = 1/2 g t^2 time to fall 2.5 m

t = (5 / 9.8)^1.2 = .714 sec time in air

v = a t = 9.8 * .714 = 7 m/s initial vertical speed

Check:

S = v t - 1/2 g t^2 where v is the initial vertical speed

S = 7 * .714 - 4.9 * .714^2 = 2.5 m total vertical distance traveled
