What is the control group

Physics
2 answers:
otez555 [7]3 years ago
8 0

A control group in a scientific experiment is a group separated from the rest of the experiment, where the independent variable being tested cannot influence the results. This isolates the independent variable 's effects on the experiment and can help rule out alternative explanations of the experimental results.

1.15) What distance will 650 joules of work move a box weighing 50 newtons?​
son4ous [18]

Answer:

The answer is 13 however make sure if they ask for a certain measurement like meter answer it by saying 13 meters.

Explanation:

This basically turns into basic algebra if you know the formula for work. The formula for work is W=F*d  

Here are the variables that you know 650J=50N*d so you need d.

All you do is divide 650J by 50N and you get a total of 13 (meters since I don't know what they want you to put it in).

A wire carries a current in the x-direction. a positively charged particle moves in the –x-direction near the current-carrying w
Maslowich

A magnetic field is experienced by the charged particle in the +y direction.

Discussion:

  • The right thumb rule states that the magnetic field lines will be perpendicular in the area to the conductive wire's left in which the electric potential is traveling.
  • The direction of the current may be determined by looking at the positive charge's (X direction) motion. According to Fleming's left-hand rule, the force on a positive charge will be in the +y direction because the positive charge is moving in a leftward direction, which will also be the direction of the current.

Fleming's left-hand rule:

In accordance with Fleming's Left Hand Rule, the thumb, forefinger, and middle finger of the left hand should be positioned perpendicular to one another. The thumb should point in the path of the power exerted by the conductors, the forefinger should point in the magnetic field direction, and the middle finger should point in the path of the electric current.

How many coulombs of positive charge are there in 3.60 kg of plutonium, given its atomic mass is 244 and that each plutonium ato
PtichkaEL [24]

1 mole of plutonium = 244 gm

3.6 kg of plutonium = 3.6 × 1000 = 3600 gm

Number of moles = 3600 ÷ 244 = 14.754 moles

One moles of plutonium contains protons = \( 6.023 \times {10}^{23} \times 94 \)

Total number of protons in 14.754 moles = \( 6.023 \times {10}^{23} \times 94 \times 14.754 \)

Total number of protons in 14.754 moles = \(8353.15 \times {10}^{23}\)

Total Positive charge = \(8353.15 \times {10}^{23} \times 1.6 \times {10}^{-19}\)

Total positive charge = \(13365.04 \times {10}^{4}\) C
