Two ions with masses of 5.29×10−27 kg move out of the slit of a mass spectrometer and into a region where the magnetic field is

riadik2000 [5.3K]

Answer:

0.132 m

Explanation:

$m$ = mass of the ion = 5.29 x 10⁻²⁷ kg

$q$ = magnitude of charge on singly charged ion = 1.6 x 10⁻¹⁹ C

$r$ = radius of circular path followed by singly charged ion

$v$ = speed of the ion = 1.13 x 10⁶ m/s

$B$ = magnitude of the magnetic field = 0.283 T

Radius of the circular path is given as

$r = \frac{mv}{qB}$

$r = \frac{(5.29\times 10^{-27})(1.13\times 10^{6})}{(1.6\times 10^{-19})(0.283)}$

$r$ = 0.132 m

A 296-kg motorcycle is accelerating up along a ramp that is inclined 26.2° above the horizontal. The propulsion force pushing th

Alexeev081 [22]

Answer:

The magnitude of the motorcycle's acceleration is 5.20 m/s².

Explanation:

Given that,

Mass of motorcycle = 296 kg

Angle = 26.2°

Force on motorcycle= 3106 N

Force = 286 N

We need to calculate the magnitude of the motorcycle's acceleration

The net force acting on the motorcycle

Using newton's second law

$ma=F_{p}-F_{air}-F_{g}$

$ma=F_{p}-F_{air}-mg\sin\theta$

Put the value into the formula

$296a=3106-286-296\times9.8\times\sin26.2$

$a=\dfrac{3106-286-296\times9.8\times\sin26.2}{296}$

$a=5.20\ m/s^2$

Hence, The magnitude of the motorcycle's acceleration is 5.20 m/s².

Equations to use: v= λ ∙ f v=d/t

Margarita [4]

b. 460.8 m/s

Explanation:

The relationship between the speed of the wave along the string, the length of the string and the frequency of the note is

$f=\frac{v}{2L}$

where v is the speed of the wave, L is the length of the string and f is the frequency. Re-arranging the equation and substituting the data of the problem (L=0.90 m and f=256 Hz), we can find v:

$v=2Lf=2(0.90 m)(256 Hz)=460.8 m/s$

c. 18,000 m

Explanation:

The relationship between speed of the wave, distance travelled and time taken is

$v=\frac{d}{t}$

where

v = 6,000 m/s is the speed of the wave

d = ? is the distance travelled

t = 3 s is the time taken

Re-arranging the formula and substituting the numbers into it, we find:

$d=vt=(6,000 m/s)(3 s)=18,000 m$

When an apple is cut, it often turns brown. What does the color change indicate?

IrinaK [193]

When an apple is cut (or bruised), oxygen is introduced into the injured plant tissue. When oxygen is present in cells, polyphenol oxidase (PPO) enzymes in the chloroplasts rapidly oxidize phenolic compounds naturally present in the apple tissues to o-quinones, colorless precursors to brown-colored secondary products. so it will be c
