The law of conservation of energy asserts that although energy can change its form, it cannot be created or destroyed. Energy is a conserved quantity. The International System of Units (SI) uses the joule as the unit of measurement for energy, which is defined as "the energy transferred to an object by the work of moving it a distance of one metre against a force of one newton."

A wooden block contains some nails so that its density is exactly equal to that of water. if it is placed in a tank of water and released from rest when it is completely submerged, it will?
A wooden block contains some nails so that its density is exactly equal to that of water. if it is placed in a tank of water and released from rest when it is completely submerged, it will remain where it is released.
The concept of density seeks to measure the weight of an object in relation to its size. It is the measure of how packed together the particles of that object are. An object placed in a liquid displaces a certain volume of the liquid, based on the relative density of the object and the liquid.
If an object is less dense than a liquid in which it is placed, it displaces a smaller volume of the liquid than its volume, hence only some part of the object will be seen to be under the liquid, the other part will float.
If an object is denser than the liquid in which it is placed, it displaces a larger volume of the liquid than its own volume, making the object to sink and is submerged, sometimes to the bottom of the liquid, but mostly below the point at which it was released.
Finally, if the density of an object and the liquid into which it is submerged is the same. the object's mass per unit volume is the same as the liquid's mass per unit volume, hence the weight and force created due to density will balance and cancel each other out hence making the object to remain where it was submerged.

Which group of theorists believe that we should study only what we can directly observe and measure?
Learning Through Observation
Albert Bandura believed that associations and direct reinforcements simply could not account for all learning. "Learning would be exceedingly laborious, not to mention hazardous if people had to rely solely on the effects of their own actions to inform them what to do," he famously wrote in his 1977 book Social Learning Theory.
Instead, he proposed that much of learning takes place through observation. Children observe the actions of those around them, particularly caregivers and siblings, and then imitate these behaviors. In his well-known Bobo doll experiment, Bandura revealed just how easily children could be led to imitate even negative actions. Children who watched a video of an adult beating up a large inflatable doll were then much more likely to copy those same actions when given a chance.
Perhaps most importantly, Bandura noted that learning something does not necessarily result in a change in behavior. Children frequently learning new things through observation, but might not engage in such behaviors themselves until there is actually a need or motivation to utilize the information.

A stretched string is observed to have four equal segments in a standing wave driven at a frequency of 480 hz. what driving frequency will set up a standing wave with five equal segments?
600Hz is the driving frequency needed to create a standing wave with five equal segments.
To find the answer, we have to know about the fundamental frequency.
How to find the driving frequency?The following expression can be used to relate the fundamental frequency to the driving frequency;f(n) = n * f (1)
where, f(1) denotes the fundamental frequency and the driving frequency f(n).
The standing wave has four equal segments, hence with n=4 and f(n)=4, we may calculate the fundamental frequency.f(4) = 4× f (1)
480 = 4× f(1)
f(1) = 480/4 =120Hz.
So, 120Hz is the fundamental frequency.
To determine the driving frequency necessary to create a standing wave with five equally spaced peaks? For, n = 5,f(n) = n 120Hz,
f(5) = 5×120Hz=600Hz.
Consequently, 600Hz is the driving frequency needed to create a standing wave with five equal segments.

Let 'T' be the initial temperature.
Substitute all the value in formula to get the equation.
509000 = 3090 × 4.186 × (100 - T)
100 - T = 39.35
T = 100 - 39.35
T = 60.64
Therefore, the initial temperature of the water was 60.64 degree Celsius.

A cardiac pacemaker can be affected by a static magnetic field as small as 1. 7 mt. how close can a pacemaker wearer come to a long, straight wire carrying 28 a?
A cardiac pacemaker can be affected by a static magnetic field as small as 1. 7 mt. pacemaker wearer comes to a long, straight wire carrying 28 amperes.
A pacemaker is a device that regulates an unsteady heartbeat. A pacemaker is inserted into one or more cardiac chambers using flexible, insulated wires called leads. The electrical pulses needed to change the heart rate are delivered by these lines. Some of the most recent pacemakers don't need leads.
The risk of problems is often quite low while having a pacemaker put. The primary worry is that the pacemaker will no longer be able to regulate the heartbeat due to a malfunction or a wire that has moved out of place. The average patient lived 101.9 months (or 8.5 years) after having a pacemaker implanted; at 5, 10, 15, and 20 years later, 65.6%, 44.8%, 30.8%, and 21.4% of patients were still living, respectively.

The closest distance peacemaker come to is r=3mm.
How to find closest distance?Given data:-
B=1.7mt.
I=28A.
by using the equation B=(μ₀I)/2πr
r=μ₀I/2πB
r=[tex]\frac{4\pi *10^{-7} Tm/A *28A}{2\pi (0.0017T)}[/tex]
r=32*[tex]10^{-4}[/tex]m
r=3.2mm.
thus from the above conclusion we can say that when magnetic field is 1.7mt and current =28A then pacemaker can come close r=3.2mm.
