A car travels 40 miles in 2 hours. If the car travels another 60 moles how long will it take to travel
Kisachek [45]

Answer:

<u><em>3 hours</em></u>

Explanation:

If the car takes 2 hours to go 40 miles, then the car can go 20 miles in 1 hour. Since the car is going 60 miles, it will take 3 hours.

Hope that makes sense :)

You name binary ionic compounds by naming the first element or the ___ first,
Nuetrik [128]

Answer:

cation, anion

Explanation:

Binary Ionic Compounds- Binary means 2, ionic relates to charges. Therefore binary ionic compounds have TWO elements, with charges that cancel eachother out. The cation (or positive charge) goes before the anion (or negative charge)

example:

NaCl

Na^+1

Cl^-1

Sodium Chloride

A proton initially at rest is accelerated by a uniform electric field. The proton moves 4.76 cm in 1.10 x 10^-6 s. Find the volt
iVinArrow [24]

Answer:

The voltage drop through which the proton moves is 39.1 V.

Explanation:

Given that,

Distance = 4.76 cm

Time t=1.10\times10^{-6}\ s

We need to calculate the acceleration

Using equation of motion

s = ut+\dfrac{1}{2}at^2

Where, s = distance

a = acceleration

t = time

Put the value in the equation

4.76\times10^{-2}=\dfrac{1}{2}\times a \times(1.10\times10^{-6})^2

a=\dfrac{2\times 4.76\times10^{-2}}{(1.10\times10^{-6})^2}

a=7.87\times10^{10}\ m/s^2

We need to calculate the voltage drop

Using formula of electric field

F=qE

F = q\dfrac{V}{d}....(I)

Using newton's second law

F = ma....(II)

Put the value of F in equation (I) from equation (II)

ma=\dfrac{qV}{d}

V=\dfrac{mad}{q}

Where, q = charge

a = acceleration

d = distance

m= mass of proton

Put the value into the formula

V=\dfrac{1.67\times10^{-27}\times7.87\times10^{10}\times4.76\times10^{-2}}{1.6\times10^{-19}}

V=39.1\ V

Hence, The voltage drop through which the proton moves is 39.1 V.

Two resistors, R1 = 25.0 ohms and
Leni [432]

Answer: 0.078

Explanation:

Given variables:

R1 = 25.0 , R2 = 64.0 , I1 = 0.200

Step 1: find V

0.200 = v/25

0.200 * 25 = v

5 = v

Step 2: Solve for I2

I = V/R

I = 5/64

I = 0.078125

Hope this helps!
