Magnetic field strength decreases as you get farther from the poles of the magnet.
ExplanationThere are three ways to change the magnetic flux across a loop: Change the strength of the magnetic field across the surface (raise, reduce).
It doesn’t matter whether you move the coil while keeping the magnet fixed or the other way around if you want to change the surface area of the loop (raise by expanding the loop, decrease by reducing the loop).
The way they move in respect to one another determines how the magnetic flux across the coil changes. The direction in which the galvanometer needle deflects depends on which side of the coil confronts the magnet when you move it. The coil ends are labelled to show which goes to the red wire and which goes to the black wire.

b. moving with constant velocity.
c. having no acceleration.
d. all of these
An object in mechanical equilibrium is an object: a. at rest.
A system is at rest or equilibrium when the sum of all the forces acting on the body or the resultant force of the system is equal to zero (0), therefore, there is an equilibrium between them.
The general formula for calculating the resultant force on an object and determined if it is in mechanical equilibrium is the following:
Fr = ∑F

Action and reaction forces comprise the parts of select one:
a. a single interaction.
b. two interactions.
Action and reaction forces comprise the parts of a. a single interaction.
For every action, there is an equal and opposite reaction. According to Newton's third law there is an equal (in size) and opposite (in direction) reaction force for every action force. That means that forces result from interactions.
The force exerted on an object is the action, and the force experienced by the object is the reaction.
Some forces result from contact interactions like frictional, tensional and other forces are results of actions at a distance interaction like gravitational, electrical, magnetic.

If the releases 39.4 kj of energy, how many kilocalories does it release? (1 cal = 4.184 j) (round off answer to 2 decimal place
By using unit conversion, the energy released in kilocalories is 9.42 kcal.
We need to know about unit conversion to solve this problem. There are several energy units which able to explain how much the energy is such as calories and joule. The energy unit can be converted to another unit by unit conversion. The unit conversion of calorie to joule is
1 cal = 4.184 joule
From the question above, we know that
E = 39.4 kJ
By using the unit conversion, we can convert the energy into calorie
E = 39.4 kJ
E = 39.4 x 10³ J
E = 39.4 x 10³ / 4.184 cal
E = 9.42 x 10³ cal
E = 9.42 x 10³ /10³ kcal

A certain reaction has an activation energy of 43.41 kj/mol. at what kelvin temperature will the reaction proceed 7.50 times faster than it did at 317 k?
The temperature required to increase the reaction rate by 7.50 times will be 332.63 K .
The speed at which a chemical reaction proceeds is known as the reaction rate.
We are given that ,
The activation energy = E = 43.41 kj/mol
Initial temperature = T₁ = 317 k
Therefore we can write as, the temperature at which reaction has 7.50 times faster than at 317 K be T₂ . Then the rate of a reaction increases because the rate constant increases with temperature.
The relation between temperatures, rate constants, and activation energy is given as,
(k₁/k₂) = E/R [(1/T₁ ) - (1/T₂)]
Where, k₁ is rate constant at temperature T₁ and k₂ is rate constant at temperature T₂ & R is gas constant having value 8.314 j/kmol .
Thus putting all the given values in above equation then we get,
7.50k/k = (434100 j/mol)/(8.314j/kmol)[(1/317k) - (1/T₂)]
7.50 = 52213.1344 k [ 0.00315 k⁻¹ - 1/T₂]
1/T₂ = 0.00315 K⁻¹ - (7.50/52213.1344)
T₂ = 332.63 K
Therefore the temperature required to increase the reaction rate by 7.50 times is given as T₂ = 332.63 K
