Mass is measured using _____.scales
a triple beam balance
a mass meter
all of the above

Answers

Answer 1

Answer:

Answer;

-A triple beam balance

Explanation;

-Mass is the amount of matter in an object. Move to a different planet and an object's weight will change, but its mass will be the same. There are a couple of ways to measure mass. The Mass of an object doesn't change when an object's location changes. Weight, on the other hand does change with location.

-Mass is measured by using a balance comparing a known amount of matter to an unknown amount of matter. Weight is measured on a scale.

Answer 2

Answer:

Mass is measured using scales, a triple beam balance, or a mass meter.

What are scales used for?

Scales are commonly used for everyday measurements, where an object's weight is indirectly measured by the force it exerts on a spring or load cell.

A triple beam balance is a type of mechanical balance that uses a combination of sliding weights to determine mass.

Calculate surface tension of an enlarged radius of 4cm to 6cm and amount of work necessary for enlargement was 1.5×10^-4 joules

Answers

Answer:

$T=7.5*10^(-5)$

Explanation:

From the question we are told that:

Radius $r=2cm$

Work done $W=1.5×10^-4 joules$

Generally the equation for Work done is mathematically given by

$W=T.dA$

Therefore

$T=(W)/(dr)$

$T=(1.5*10^(-4))/(2)$

$T=7.5*10^(-5)$

Which of these is the most likely impact of solar prominence on Earth? A) rerouting of aircraft
B) increase in severity of hurricanes
C) long-term electrical power generation
D) improvement in satellite communication

Answers

Solar prominences themselves are of no concern because they are visible in the Hydrogen Alpha wavelength. They are anchored in place by magnetic fields. When these fields break or reconnect, it can send the plasma that makes up the prominence away from the sun. If one of these clouds impacts Earth, they are called CMEs or coronal mass ejections. Depending on the magnetic orientation of the cloud with respect to Earth's the CME can break down our magnetic field resulting in geomagnetic storms, aurorae, power grid fluctuations, and particle radiation near the poles, satellite single upset events, and radio blackouts.

Thus, letter a is the answer.

Answer:

A) rerouting of aircraft

Explanation:

An electron travels with speed 6.0 106m/s between the two parallel charged plates shown in the figure. The plates are separated by 1.0 cm and are charged by a200 V battery.What magnetic field strength will allow the electron to pass between the plates without being deflected?

Answers

The magnetic field strength will allow the electron to pass between the plates without being deflected is 0.0033 T.

Electric field strength

The electric field strength of the electron is calculated as follows;

E = V/d

E = 200/(0.01)

E = 20,000 V/m

Magnetic field strength

The magnetic field strength is related to electric field in the following formula;

qvB = qE

vB = E

B = E/v

B = (20,000)/(6 x 10⁶)

B = 0.0033 T

Thus, the magnetic field strength will allow the electron to pass between the plates without being deflected is 0.0033 T.

Answer:

3.3 mT

Explanation:

First of all, we need to find the strength of the electric field between the two parallel plates.

We have:

$\Delta V=200 V$ (potential difference between the two plates)

$d=1.0 cm=0.01 m$ (distance between the plates)

So, the electric field is given by

$E=(\Delta V)/(d)=(200 V)/(0.01 m)=2\cdot 10^4 V/m$

Now we want the electron to pass between the plates without being deflected; this means that the electric force and the magnetic force on the electron must be equal:

$F_E = F_B\nqE=qvB$

where

q is the electron charge

E is the electric field strength

v is the electron's speed

B is the magnetic field strength

In this case, we know the speed of the electron: $v=6.0\cdot 10^6 m/s$ , so we can solve the formula to find B, the magnetic field strength:

$B=(E)/(v)=(2\cdot 10^4 V/m)/(6.0\cdot 10^6 m/s)=0.0033 T=3.3 mT$

how far can a person run in 15 minutes if he or she runs a at an average speed of 16 km/hr? what is the runners distance traveled in miles

Answers

To find this, we would divide 60 by 15 because there is 60 minutes in an hour and we're trying to find how much of 16 km he can run in 15 minutes. When we divide 60 by 15 we get 4. Now we divide 16 by 4 to get 4. So he can run 4 km in 15 minutes.
