Match the half life and time information to the percentage of radioactive isotope left.

A bicycle has a momentum of 36 kg* m/s and a very!I city of 4 m/s.What is the mass of the bicycle?

Strike441 [17]

p = 36 kgm/s

v = 4m/s

we know that,

p = mv

so,

$m = \frac{p}{v}$

$m = \frac{36}{4}$

$m = 9kg$

Vehicles equipped with disc brakes incorporate a mechanically operated drum-style parking brake in the center of the rear disc brake rotors, commonly called a top hat parking brake.

<h3>What is top hat parking brake?</h3>

The top hat drum style of parking brake system is called the top hat rotors because of how big the middle part is compared to regular rotors.

In this type of parking brake system, the vehicle is equipped with disc brakes which incorporate a mechanically operated drum-style parking brake in the center of the rear disc brake rotors.

Thus, vehicles equipped with disc brakes incorporate a mechanically operated drum-style parking brake in the center of the rear disc brake rotors, commonly called a top hat parking brake.

The electric field strength between the plates of a simple air Capacitor is equal to the voltage across the plates divided by th

exis [7]

Answer:

$d=\frac{112\,V}{1100\,\frac{V}{cm}} \\d=\frac{28}{75} \,cm=0.101818.. \,cm$

Explanation:

Recall that the equation for the electric field intensity between the plates of a capacitor is given by:

$E=\frac{\Delta V}{d}$

where E is the electric field, $\Delta V$ is the voltage across the plate of the capacitor, and "d" is the separation (distance) between the capacitor's plates.

So we need to solve for the distance in the equation above, but also make sure that the units for electric field and potential difference are in agreement. We then write the electric field strength in V/cm :

1.1kV/cm = 1100 V/cm

Now in the equation:

$E=\frac{\Delta V}{d}\\1100\,\frac{V}{cm} =\frac{112\,V}{d\\}\\d=\frac{112\,V}{1100\,\frac{V}{cm}} \\d=\frac{112}{1100} \,cm\\d=\frac{28}{75} \,cm=0.101818.. \,cm$

A manufacturer sells two goods, one at a price of $1000 a unit and the other at a price of $16,500 a unit. A quantity q1 of the

vaieri [72.5K]

Answer:

manufacturing cost = $16.5 q₂ + $1 q₁ - $ 5

Explanation:

given,

one unit price of first good is = $ 1000

one unit price of second good is = $ 16500

quantity of the first good = q₁

quantity of the second good = q₂

total cost to the manufacturer = $ 5000

revenue from good one = $1000 q₁

revenue from second good = $16500 q₂

manufacturing cost = total revenue - total manufacturing cost

manufacturing cost = $16500 q₂ + $1000 q₁ - $ 5000

but in the question we have to answer in thousands of dollar

so, divide the result by 1000

manufacturing cost = $16.5 q₂ + $1 q₁ - $ 5
