Which characteristic should a good scientific question have?

Answers

Answer 1

Answer:

Answer:

explained

Explanation:

A Good scientific question must lead to a hypothesis and must help in answering the reason for any observation. It should be testable, meaning it can be performed as an experiment. At the same time the formed hypothesis can be falsifiable, that is it can fail. For example, the sound generated by a moving car. The question can be is there any correlation between speed of car and the noise it generate. It can result in a hypothesis that at higher speed more noise occur. It can very easily tested.

Answer 2

Answer: A good scientific question should be pre-determined and also have a meaning or relation to science.

What is the acceleration of a 10 kg object if a force of a 3 N is applied?

Answers

The acceleration of the object is 0.3 m/s² when the force applied on the object.

What is force?

Physics defines force as the push or pull that modifies the velocity of a massed object. An external force is a force that can change a body's resting or moving condition. There is a magnitude and a direction to it.

You may measure the Force using a spring balance. The unit of force in the SI is the Newton.

According to Newton's second law of motion: force applied on any object is equal to the change in momentum of the object per unit time.

Hence, F = dP/dt

F = m dv/dt = ma

So, force = mass × acceleration

Given force applied on the object = 3 N

Mass of the object = 10 kg

Hence, the acceleration of the object is = Force ÷ mass

= ( 3 ÷ 10) m/s²

= 0.3 m/s²

How many gallons are in a cubic gallon?

Answers

There's no such thing as a "cubic gallon". A 'gallon' is already a unit of volume,
only without the word 'cubic' in it.

If you like to play with different units of measure, here are a few conversions:

1 gallon = 231 cubic inches
1 cubic foot = 1,728 cubic inches = about 7.4805 gallons

1 cubic meter = 1,000 liters = 1 million cubic centimeters = about 264.17 gallons

What is the speed of a wave yhat has a frequency of 2.0Hz

Answers

You can't tell the speed of a wave from only its frequency.

You also need to know either the wavelength, or what substance
the wave is traveling through.

-- If you know the frequency AND wavelength, you can
calculate the speed.

-- If you know what substance the wave is traveling in, you can
probably determine its speed without knowing anything else about it.

A lamp can work on 50V mains taking 2 amps. What value of resistance must be connected in series with it, so that it can be operated from 200V mains giving the same power?

Answers

The resistance of the lamp is apparently 50V/2A = 25 ohms.

When the circuit is fed with more than 50V, we want to add
another resistor in series with the 25-ohm lamp so that the
current through the combination will be 2A.

In order for 200V to cause 2A of current, the total resistance
must be 200V/2A = 100 ohms.

The lamp provides 25 ohms, so we want to add another 75 ohms
in series with the lamp. Then the total resistance of the circuit is
(75 + 25) = 100 ohms, and the current is 200V/100 ohms = 2 Amps.

The power delivered by the 200V mains is (200V) x (2A) = 400 watts.

The lamp dissipates ( I² · R ) = (2² · 25 ohms) = 100 watts.

The extra resistor dissipates ( I² · R) = (2² · 75 ohms) = 300 watts.

Together, they add up to the 400 watts delivered by the mains.

CAUTION:
300 watts is an awful lot of power for a resistor to dissipate !
Those little striped jobbies can't do it.
It has to be a special 'power resistor'.
300 watts is even an unusually big power resistor.
If this story actually happened, it would be cheaper, easier,
and safer to get three more of the same kind of lamp, and
connect THOSE in series for 100 ohms. Then at least the
power would all be going to provide some light, and not just
wasted to heat the room with a big moose resistor that's too
hot to touch.
