Answer 1

Answer:

Seconds/Division

An oscilloscope measures time-varying waveform. Electrical input signal is concerted into detectable trace on a screen by converting electricity into light. Time period is plotted along the x -axis as the horizontal component. The center vertical line (y-axis) represents the voltage.

How could you keep an objects acceleration the same if the force acting on the object were double?

Answers

You can keep an object's acceleration constant if the force acting on it is double by adding another force going in the opposite direction of the first force. The second force will have to be as strong as the first force was originally in order for the acceleration to be the same. This is the same concept as if you have 2 of something, double it to get 4, and subtract 2 again. You'll end up with the same value you started with.

What instrument is used to measure relative humidity and how does it work?

Answers

The measurement of humidity may be done directly by a hygrometer.

But the usual instrument is called a psychrometer, which uses two thermometers to obtain temperatures that indicate the relative humidity.

A psychrometer is an instrument that uses the difference in readings between two thermometers, one having a wet bulb and the other having a dry bulb, to measure the moisture content or relative humidity of air. When air is saturated, the bulbs have the same temperature. When it is less than saturated, the moisture around the wet bulb evaporates, cooling the wet bulb until it is cooled to the temperature where the concentration of water vapor in the air would saturate air at that temperature.

psychrometer

Relative humidity is a measure of water vapor in the air compared with the maximum amount of water vapor the air can hold at that temperature. It can be measured by using a variety of instruments, such as a thin polymer film, a psychrometer, a dew cell, and a hair hygrometer.

A hygrometer.

Thermo-hygrograph. It uses two thermometers, one gives dry temperature is is hung in the air, while the second one is dipped in water with the help of a wick. As the evaporation of water depends on the relative humidity in the air, when there is a big difference in dry and wet temperatures it means that humidity is low and vice versa. The exact humidity is found out with the help of a table Relative humidity can be measured by a psychrometer .

The slope on a distance-time graph shows a ball moving from 20 m to 40 m in 1 s and from 40 m to 80 m in the next second

Answers

Slope in the first second: 20 m/s

Slope in the next second: 40 m/s

Average slope: 30 m/s

Explanation:

On a distance-time graph, the slope of the curve represents the speed of the object.

In fact, we have:

The distance covered is the change in the y-variable, so $\Delta y$
The time elapsed is the change in the x-variable, so $\Delta x$

Speed is the ratio between distance and time, therefore

$speed = (distance)/(time)=(\Delta y)/(\Delta x)$

which corresponds to the slope of the line.

In this problem, we have a ball moving from 20 m to 40 m in 1 s, so

$distance = 40-20 = 20 m = \Delta y$

$time = 1 s = \Delta x$

So the slope in the first second is

$(\Delta y)/(\Delta x)=(20)/(1)=20 m/s$

In the next second, the ball moves from 40 m to 80 m, so

$distance = 80-40 = 40 m = \Delta y$

$time = 1 s = \Delta x$

So the slope in the next second is

$(\Delta y)/(\Delta x)=(40)/(1)=40 m/s$

While if we consider the overall graph in the 2 seconds, we have

$distance = 80-20 = 60 m = \Delta y$

$time = 2 s = \Delta x$

So the average slope is

$(\Delta y)/(\Delta x)=(60)/(2)=30 m/s$

A weatherman reports, "The storm waves are about 2 meters high and about 35 meters apart." What properties of waves is the reporter describing?

Answers

Answer:

Amplitud = 2 m

wavelength = 35 m

Explanation:

The waves are described by an equation of the form

Y = A sin (kx -wt)

With k = 2 π/λ

With A is the amplitude of the wave, λ the wavelength and w the velocity

If we analyze the reporter's data, the maximum height of the value from zero to the highest, which corresponds to the amplitude of the wave

The other value 35 m between each wave corresponds to the distance between the ridges that is equivalent to the wavelength

2 meters high = Amplitude (height at the maximum)
35 meters apart makes gives frequency (how many per meter, or how many per 100 meters etc...)
