Answer:

Radio waves: have a longer wavelength

X-rays: have a higher frequency

Both: they travel at the same speed

Explanation:

Missing part of the question:

"Isla made a diagram to compare x-rays and radio waves. what should isla write in the areas marked a, b, and c?"

X-rays and radio waves are both types of electromagnetic waves.

Electromagnetic waves consist of oscillations of the electric and the magnetic fields in a plane perpendicular to the direction of propagation the wave.

All electromagnetic waves travel in a vacuum always at the same speed, the speed of light:

$c=3.0\cdot 10^8 m/s$

Electromagnetic waves are also classified into 7 different types, according to their wavelength/frequency. From longest to shortest wavelength (and from lowest to highest frequency, since frequency is inversely proportional to wavelength), they are:

Radio waves (>1 m)

Microwaves (1 mm - 1 m)

Infrared (750 nm - 1 mm)

Visible light (380 nm - 750 nm)

Ultraviolet (10 nm - 380 nm)

X-rays (0.01 nm - 10 nm)

Gamma rays (<0.01 nm)

Therefore, the correct matches are:

Radio waves: have a longer wavelength

X-rays: have a higher frequency

Both: they travel at the same speed

Explanation:

u=166m/s, v=0(at it's highest point final velocity is zero), a=9.8m/s², t=8.6s

by the formula, S=ut+½at².

S=[166×8.6+½.×9.8×(8.6)²]. ...by calculation

S = 1427.6+362.404

S=1790.004m

If 10. joules of work must be done to move 2.0 coulombs of charge from point A to point B in an electric field, the potential di

masya89 [10]

The equation for work (W) done by an electric field is:

W = qΔV

where q is the magnitude of the charge and ΔV is the potential difference. The question gives you W and q, so plug n' play to find ΔV:

10 = 2ΔV
ΔV = 5

You and some friends decide to take a canoe trip down the Wood River. The stretch of river you are traveling flows at a roughly

Anna35 [415]

Answer:

t= 1.2 hours

Explanation:

Define first di distance between the points, so

$\bar{x}_{canoe}=2*(2+3)=10$

$\bar{x}_{water}=2*2=4$

The distance is

$d= \bar{x}_{canoe}- \bar{x}_{water}$

$d= 10-4 = 6miles$

$t = \frac{x}{v} = \frac{6}{2+3}$

$t= 1.2 hours$

What is the passenger's apparent weight at t=1.0s?

Fittoniya [83]

Answer:

For the complete question provided in explanation, if the elevator moves upward, then the apparent weight will be 1035 N. While for downward motion the apparent weight will be 435 N.

Explanation:

The question is incomplete. The complete question contains a velocity graph provided in the attachment. This is the velocity graph for an elevator having a passenger of 75 kg.

From the slope of graph it is clear that acceleration at t = 1 sec is given as:

Acceleration = a = (4-0)m/s / (1-0)s = 4 m/s^2

Now, there are two cases:

1- Elevator moving up

2- Elevator moving down

For upward motion:

Apparent Weight = m(g + a)

Apparent Weight = (75 kg)(9.8 + 4)m/s^2

<u>Apparent Weight = 1035 N</u>

For downward motion:

Apparent Weight = m(g - a)

Apparent Weight = (75 kg)(9.8 - 4)m/s^2

<u>Apparent Weight = 435 N</u>

1hp is written in electric motor what does it mean

Angelina_Jolie [31]

Explanation:

The horsepower (hp) is a unit in the foot-pound-second ( fps ) or English system, sometimes used to express the rate at which mechanical energy is expended. It was originally defined as 550 foot-pounds per second (ft-lb/s). A power level of 1 hp is approximately equivalent to 746 watt s (W) or 0.746 kilowatt s (kW).
