Answer:

Mechanical advantage = 15

Explanation:

Given the following data;

Output force = 3000N

Input force = 200N

To find the mechanical advantage;

Mechanical advantage = output force/input force

Substituting into the equation, we have

Mechanical advantage = 3000/200

Mechanical advantage = 15

Lillle is running. She increases her initial speed of 30 km/h to 40 km/h so she
Alex777 [14]

Answer

200km {h}^{ - 2}

Explanation

Acceleration =  \frac{final \:  \:  \: velocity - initial \:  \: velocity }{time}  \\  =  \frac{(40 - 30)km {h}^{ - 1} }{0.05h}  \\  =  \frac{10}{0.05}  \\  = 200km {h}^{ - 2}

Hope this helps you.

Let me know if you have any other questions :-):-)

PROBLEM 5 (Problem 4-145 in 7th edition) Consider a well-insulated horizontal rigid cylinder that is divided into two compartmen
kari74 [83]

Answer:

The answer is "\bold{83.8^{\circ} \ C}".

Explanation:

Formula for calculating the mass in He:

\to m = \frac{PV}{RT}\\

        = \frac{500 \times 1}{ 2.0769 \times (40 + 273)}\\\\ = \frac{500 }{ 2.0769 \times 313}\\\\ = \frac{500 }{ 650.0697}\\\\= 0.76914 \ Kg

Formula for calculating the mass in N_2:

\to m = \frac{PV}{RT}\\

        = \frac{500 \times 1}{ 0.2968 \times (120+ 273)}\\\\ = \frac{500 }{ 0.2968 \times 393}\\\\ = \frac{500 }{ 116.6424}\\\\= 4.2866\ Kg

by using the temperature balancing the equation:

T' = \frac{mcT (He) + mcT ( N_2 )}{ mc (He) + mc ( N_2)}

    = \frac{0.76914 \times 3.1156 \times 313 + 4.2866 \times 0.743 \times393}{  0.76914 \times 3.1156 + 4.2866 \times 0.743} \\\\ = 357  \ \ K \approx  83.8^{\circ} \ C

I don’t understand this question
hichkok12 [17]

It's Z.

Without any force acting on it an object travels in a straight line.

In order to bend away from a straight line the object needs a force acting on it.

In order to move along a circle, the force on the object points toward the center of the circle. It's called the centripetal force.

Since the object's direction is changing it has acceleration.

The acceleration points toward the center of the circle.

Pierce conducts an experiment in which waves collide in a way that the energy increases. What has occurred? refraction reflectio
Vitek1552 [10]

Answer:

constructive interference.

Explanation:

Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver.

Generally, the most commonly used electromagnetic wave technology in telecommunications is radio waves.

Radio waves can be defined as an electromagnetic wave that has its frequency ranging from 30 GHz to 300 GHz and its wavelength between 1mm and 3000m.

In this scenario, an experiment is conducted by Pierce in which waves collide in a way that the energy increases. Thus, this is an example of constructive interference i.e constructive interference has occurred.

An interference occurs when two pair of waves such as sound and light waves pass through each other i.e crossing each other's path while traveling through the same medium or space.
