Crazy boy [7]

The correct answer is  their difference in the charge to  mass ratio  a mass spectrometer, a compound is first vaporized and converted into ions .

Mass spectrometry is a technique for determining the mass-to-charge ratio (m/z) of one or more molecules in a sample. These measurements are frequently used to calculate the precise molecular weight of the sample components.

The speed at which positively charged ions move through a vacuum chamber toward a negatively charged plate is measured by mass spectrometers. ToF, magnetic sector, and quadrupole mass spectrometers are all commonly used in SIMS instrumentation.The MS/MS has three major advantages: the ability to study numerous molecules regardless of whether they are from the same structural family or not; the ability to highlight the specific metabolites of a disease; and it is an automated technique that allows for large-scale analysis.

A building is being knocked down with a wrecking ball, which is a big metal sphere that swings on a 15-m-long cable. You are (un
Charra [1.4K]

Answer:

1.9 s

Explanation:

We are given that

Length of cable=l=15 m

We have to find the time you have to move out of the way.

We know that

Time period,T=2\pi\sqrt{\frac{l}{g}}

Where g=9.8m/s^2

By using the formula

T=2\pi\sqrt{\frac{15}{9.8}}

T=2\times 3.14\times \sqrt{\frac{15}{9.8}}=7.77 s

Time you have to move out

t=\frac{T}{4}=\frac{7.77}{4}=1.9 s

Hence,time you have to move out of the way=7.77 s

A ball is thrown straight down with a speed of Va2.00 from a building 40.00 meters high. How much S time passes before the ball
-Dominant- [34]

Answer:

Option C is the correct answer.

Explanation:

Considering vertical motion of ball:-

Initial velocity, u =  2 m/s

Acceleration , a = 9.81 m/s²

Displacement, s = 40 m

We have equation of motion s= ut + 0.5 at²

Substituting

   s= ut + 0.5 at²

    40 = 2 x t + 0.5 x 9.81 x t²

   4.9t²  + 2t - 40 = 0

   t = 2.66 s   or t = -3.06 s

So, time is 2.66 s.

Option C is the correct answer.

What is the potential energy of a 2kg object placed 6m above<br> the surface of the Earth?
zalisa [80]

Answer:117.6joules

Explanation:

Mass(m)=2kg

Height(h)=6m

Acceleration due to gravity(g)=9.8m/s^2

Potential energy(PE)=?

PE=m x g x h

PE=2 x 9.8 x 6

PE=117.6joules
