Resistance = (voltage) / (current)

Resistance = (52 V) / (2 A)

<em>Resistance = 26 ohms</em>

At some airports there are speed ramps to help passengers get from one place to another. A speed ramp is a moving conveyor belt
Harrizon [31]

Answer:

It will take you 30.8 s to travel the 120 m of the ramp.

Explanation:

Hi there!

The equation for the position of an object moving in a straight line is:

x = x0 + v * t

Where:

x = position at time t

x0 = initial position

v = velocity

t = time

In this case, we will consider the start of the ramp as the origin of our reference system so that x0 = 0.

Now, let´s calculate the speed of the person walking on the ground:

x = v * t

120 m = v * 72 s

v = 120 m / 72 s

v = 1.7 m/s

If you walk on the ramp with that speed, your total speed will be your walking speed plus the speed of the ramp because both are in the same direction. Then, using the equation for the position:

x = v * t

In this case, v = speed of the ramp + walking speed

v = 2.2 m/s + 1.7 m/s = 3.9 m/s

120 m = 3.9 m/s * t

t = 120 m / 3.9 m/s = 30.8 s

It will take you 30.8 s to travel the 120 m

A conveyor belt is used to send burgers through a grill- ing machine. If the grilling machine is 1.2m long and the burgers requi
puteri [66]

Answer:

Rate = 1.71 burger/min

Explanation:

Length of the conveyor belt is given as

L = 1.2 m

time taken to cook one burger is given as

t = 2.8 min = 168 s

now we can find the speed of the belt as

v = \frac{distance}{speed}

v = \frac{1.2}{168}

v = 7.14 \times 10^{-3} m/s

Now we know that the distance between two burgers is given as 25 cm

d = 0.25 m/burger

now the production rate of burgers is given as

Rate = \frac{v}{d}

Rate = \frac{7.14 \times 10^{-3} m/s}{0.25 m/burger}

Rate = 0.0286\frac{burger}{sec}

Rate = 0.0286\times 60\frac{burger}{min}

Rate = 1.71 burger/min

Which class of organic molecules includes those whose main purpose is long-term energy storage?
omeli [17]

Answer:

Fats.

Explanation:

A fat molecule which is called a Triglyceride consists of two main components which are glycerol and 3 fatty acids. Fats are solids and oils are liquids at room temperature. They also include saturated and unsaturated fats.

Cells store energy for long-term use in the form of lipids called fats which provides insulation from the environment for plants and animals.
