There are no choices available, however through my research this could be the choices for your question:

a) the speed of light
b) the dimensions of the earth´s orbit
c) the number of Saturn´s moons
<span>d) the use of the telescope
</span>
The most probable answer would be his miscalculations about the dimensions of the Earth's orbit which is why his experiment ultimately failed.

Does the galvanometer deflect to the left or the right when:________

igomit [66]

Complete question is;

Does the galvanometer deflect to the left or the right when

a) the magnet is being pushed in

b) the magnet is being pulled out

c) the magnet is being held steady?

Answer:

Option A - when the magnet is being pulled out

Explanation:

Faraday’s law of electromagnetic induction states that: “Voltage is induced in a circuit whenever relative motion exists between the conductor and the magnetic field, and the magnitude of the voltage will be proportional to the rate of change of the flux”.

Now, applying it to the question, When the magnet is moved towards the sensitive center of the galvanometer and then pulled out, the needle of the galvanometer will deflect away from its center position in one direction only but when it is held steady, the needle of the galvanometer will return back to zero.

A racecar is equipped with a computer that records the reading on its speedometer every second during a race. If you graph this

Westkost [7]

Since the device is a speedometer, the data it read is the speed of the racecar. Data recording involving time usually uses time as the independent variable. It was also said in the problem that it records the speed every second which shows that the time interval is constant. This means that only other data, the car's speed, is the dependent variable.

The henry's law constant for n2 is 6. 2×10−4matm at 25∘c. what pressure of nitrogen is needed to maintain a n2 concentration of

hodyreva [135]

The pressure of nitrogen which is needed to maintain a N2 concentration of 0. 53 m is 3.2 × 10^(4).

<h3>What is pressure? </h3>

It is defined as the continuous physical force applied on or against an object by something which is in contact with it.

It is also defined as the force per unit area.

<h3>What is henry's law? </h3>

The henry law constant is thr ratio of the partial pressure of compound in air to the concentration of compound in water at given temperature.

C= kp

where,

C is the concentration of compound = 0.53m

k is the henry constant = 6. 2×10−4matm

p is the pressure of compound

By substituting all the value we get,

C = 6. 2×10−4 × p

0.53 = 6. 2×10−4 × p

p = 0.53/6. 2×10−4

p = 3.2 × 10^(4)

Thus we find that the pressure needed to maintain a N2 concentration of 0. 53 m is 3.2 × 10^(4).
