TRUE or FALSE: An object's mass changes depending on which planet it is located.

Physics
1 answer:
Vedmedyk [2.9K]3 years ago
7 0

Answer:

Fales

Explanation:

That's why scientists and engineers often measure an object's mass—how much matter the object contains—rather than its weight. Mass stays the same regardless of location and gravity. You would have the same mass on Mars or Jupiter as you do here on Earth. Your weight is different on other planets due to gravity.

In a mass spectrometer, a compound is first vaporized and converted into ions, which are then separated based on a difference in
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.

Two electric motors drive two elevators of equal mass in a three-story building 10 meters tall. Each elevator has a mass of 1,00
vaieri [72.5K]

Answer:

(C) Work=9.8×10⁴J

Explanation:

Given data

mass m=1000 kg

building height=10 m

To

Find work

Solution

As we know that:

Work=mass*gravity*height\\W=mgh\\W=(1000kg)*(9.8m/s^{2} )*(10m)\\W=9.8*10^{4}J

So option (C) is correct one

A ship can carry more load than aeroplane of same size. why?​
stepladder [879]

Answer:

density of water is much greater than density of air

Explanation:

when body is in fluid it carries weight which is always equal to upthrust

upthrust is given as

upthrust= density of fluid ×strength of gravitational field g × volume of body in fluid

as volume of ship and aeroplane is same and strength of gravitational field or acceleration due to gravity is same hence upthrust depens upon density of fluid .

density of air is about 1.2 kg/m^3  and density of water is 1000kg/m^3 hence ship carries more load

a car accelerates from 2 m/s to 28m/s at a constant rate of 3 m/s^2. How far does it travel while accelerating?
xxTIMURxx [149]

Answer:

Distance, S = 130m

Explanation:

Given the following data;

Initial velocity = 2m/s

Final velocity = 28m/s

Acceleration = 3m/s²

To find the distance, we would use the third equation of motion.

V² = U² + 2aS

Substituting into the equation, we have;

28² = 2² + 2*3*S

784 = 4 + 6S

6S = 784 - 4

6S = 780

S = 780/6

Distance, S = 130m

One difference between mechanical and sound waves is
Gennadij [26K]

Light waves are different from mechanical waves, however, because they can travel through a vacuum. Light waves are just one type of electromagnetic wave. ... A polarized wave vibrates in a single plane in space. Since sound waves vibrate along their direction of propagation, they cannot be polarized.
