The formula that links voltage (V), resistance (R) and current intensity (I) is

V=RI

Solve this formula for I to get

I=\dfrac{V}{R}

Plug your values for V and R and you'll get the current.

If vector y = 21cm and vector Z=75 cm, what is vector x ?
pychu [463]
That depends on how 'x' is related to 'y' and 'z' ... like the angles between all of them, and whether they're all on the same planet. A drawing would sure help.

A particle leaves the origin with a speed of 2.1 times 106 m/s at 30 degrees to the positive x axis. It moves in a uniform elect
Verizon [17]

Answer:

-1449.69404 N/C

Explanation:

u = Velocity of particle = 2.1\times 10^6\ m/s

\theta = Angle = 30°

x = Distance = 1.5 cm

m = Mass of electron = 9.11\times 10^{-31}\ kg

q = Charge of electron = -1.6\times 10^{-19}\ C

In the case of projectile motion

x=utcosA\\\Rightarrow t=\dfrac{x}{ucosA}

The force of on the particle will balance the Electric force

ma=qE\\\Rightarrow a=\dfrac{qE}{m}

Now

y=utsin\theta-\dfrac{1}{2}at^2\\\Rightarrow y=utsin\theta-\dfrac{1}{2}\dfrac{qE}{m}t^2

If y = 0

0=utsin\theta-\dfrac{1}{2}\dfrac{qE}{m}t^2\\\Rightarrow utsin\theta=\dfrac{1}{2}\dfrac{qE}{m}t^2\\\Rightarrow t=\dfrac{2musin\theta}{qE}

\dfrac{x}{ucosA}=\dfrac{2musin\theta}{qE}\\\Rightarrow E=\dfrac{2mu^2sin\theta cos\theta}{xq}\\\Rightarrow E=\dfrac{2\times 9.11\times 10^{-31}\times (2.1\times 10^6)^2\times sin30\times cos30}{1.5\times 10^{-2}\times (-1.6\times 10^{-19})}\\\Rightarrow E=-1449.69404\ N/C

The electric field is -1449.69404 N/C

What is the coldest part of the cat’s body?
Nina [5.8K]

Answer:

It Depends Cat is indoor or outdoor But As per the body part concern that  i will Considered around the neck but Temperature Remain the same which i Analyzed too

Explanation:

A cat's normal body temperature can range from 100.5 to 102.5 degrees. Because 101.5 degrees is right in the middle, it's often referred to as a “normal” body temperature. Being that their body temperature is higher than ours, they can also tolerate higher temperatures (provided they have access to water).
