You can accelerate by changing direction, even though you don't speed up/down. Remember that acceleration is a vector so, it has a direction and a magnitude. That's why this works! Hope it helps.

Which sequence shows electromagnetic waves arranged from shorter to longer wavelengths?. A. visible light, infrared radiation, m

joja [24]

Answer: D.ultraviolet rays, visible light, infrared radiation, microwaves.

Explanation:

Shorter wavelength means higher frequency and higher energy.

Thus, the correct sequence of electromagnetic waves from shorter wavelength to longer wavelength is:

D.ultraviolet rays, visible light, infrared radiation, microwaves.

Ultraviolet rays have shorter wavelength (about 380 nm) and high energy.

Visible light has wavelength: 380 nm to 700 nm

Infrared wavelength: 700 nm to 1 mm

Microwave wavelength: 1 mm to 1 m

A car travels at a constant rate for 100 miles going due west for one hour. Then it travels at a constant rate for another 75 mi

nirvana33 [79]

Answer:

C. 100 mph west

Explanation:

Average velocity is total displacement over total time. During the first hour, the average velocity is:

v_avg = 100 mi / 1 hr

v_avg = 100 mph west

Since the velocity is constant, the instantaneous velocity at any time equals the average velocity.

v = v_avg

v = 100 mph west

Un movil pasa por el punto A en direccion hacia B (350cm más adelante) y, luego, sigue hasta el punto C. Sabiendo que pasa por B

xeze [42]

Explanation:

PRIMERO HACES EL RECUENTO DEL TIEMPO Y LO CONVIERTES EN

SEGUNDOS Y ENTONCES

t = 227 s $t_{AB}$ = 227 S - 38 s = 189 s

$t_{BC}$ = 38 s

LUEGO USANDO LA ECUACIÓN DE GALILEO GALILEI SSUPONIENDO

QUE EL MOVIL VIAJA A VELOCIDAD CONSTANTE

v = 3.50 m/189 s = 0.0185 m/s

PARA LA DISTANCIA NTRE B Y C

$x_{BC}$ = 0.0185 m/S( 38 s) = 0.703 m

LA HORA EN QUE EL MOVIL PASA POR A ES

11:43:15 - 38 s - 189 s = 11:39:29

A 9800-N automobile is pushed along a level road by four students who apply a total forward force of 600 N. Neglecting friction,

Alexandra [31]

Answer:

c). $a = 0.60 m/s^2$

Explanation:

As we know that weight of the automobile is given here

so weight = mass times gravity

$W = mg$

$9800 = m(9.8)$

$m = 1000 kg$

now from Newton's law

$F = ma$

$600 = 1000 a$

$a = \frac{600}{1000}$

$a = 0.60 m/s^2$
