What should a voltmeter that is attached to three batteries, each measuring 1.5 volts read:

Physics
1 answer:
Pie4 years ago
4 0

Answer:

The answer depends on the arrangement of the batteries either parallel or series.

If the three batteries are connected in parallel, the voltmeter will read the same voltage as the individual battery (I.e, the combine voltage will remain 1.5 Bolts)

While

If the batteries are connected in series, and are correctly connected together from positive to negative, the combine voltages will increase by adding individual battery voltage together. So for three 1.5 Volts batteries, the total voltages will be 4.5 Volts.

Explanation:

Parallel connected

Vp = 1.5 Volts

Series connection

Vs = 1.5 + 1.5 + 1.5 = 4.5Volts

The Hubble Space Telescope has a mass of 1.16*10^ 4 kg and orbits the Earth at an altitude of 5.68 * 10 ^ 5 above Earth's surfac
andrezito [222]

Answer:

E=8.13\times 10^{12}\ J

Explanation:

Given that,

The mass of a Hubble Space Telescope, m_1=1.16\times 10^4\ kg

It orbits the Earth at an altitude of 5.68\times 10^5\ m

We need to find the potential energy the telescope at this location. The formula for potential energy is given by :

E=\dfrac{Gm_1m_e}{r}

Where

m_e is the mass of Earth

Put all the values,

E=\dfrac{6.67\times 10^{-11}\times 1.16\times 10^4\times 5.97\times 10^{24}}{5.68\times 10^5}\\\\E=8.13\times 10^{12}\ J

So, the potential energy of the telescope is 8.13\times 10^{12}\ J.

Productivity increases when A. inputs increase while outputs remain the same. B. inputs decrease while outputs remain the same.
Blizzard [7]

Answer: Productivity increases when inputs and outputs increase proportionately.

Explanation:

Productivity increases when inputs and outputs increase proportionately. Input has to be directly proportional to output to be productive. This means increase in input to a system must leads to drastic increase in the output. When the output is not balanced with the amount of input, it leads to unproductivity.

Being productive can be business wise or in terms if personal growth and development.

10 N pushes a 10 kg crate to the right. Determine the acceleration of the crate.
oksano4ka [1.4K]
The rate of acceleration of the crate would be 1 m/s^2 because the equation for force is F=ma and when you plug in your numbers you get 10=10a so a=1
