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.

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.

what is relative velocity explain with example
Perfect question! So to start,
⇒ Concepts: Relative, Velocity
(Relative: - adjective- existing or having its specific nature only by relation to something else; not absolute or independent. -noun- something having, or standing in, some relation or connection to something else).
Velocity:
(1) Rapidity of motion or operation; swiftness; speed.
(2) The time rate of change of position of a body in a specified direction
(3) The rate of speed which something happens; rapidity of action or reaction.
Now, let's get onto relative velocity.
Assume you are operating a vehicle and pass another vehicle from behind. Actually, what happens is that the driver of the car behind you notices the one approaching from behind and ultimately turns around. Although the driver in front perceives it that way, the person on the ground does not see the automobile as driving backward. Relative velocity is what it is.
When riding in a car, bus, or train, you may see that numerous exterior objects are moving backward, including trees, buildings, and other objects. But are they actually regressing? No, you're very sure that the only thing moving while the trees are still on the ground is your car. What gives, therefore, that the trees seem to be going backward? Also, even if your fellow passengers are moving, they will look immovable to you since they are moving.
It's because you and your other passengers are moving in unison within your frame. It follows that you and the passengers are moving at the same speed. The trees are still, but you are moving. Trees are therefore moving relative to you and the other passenger at a certain speed. The velocity differential between you and the tree is that relative velocity.

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.

The total work done of 0.018 joules is needed to move the charges apart and double the distance between them.
We have two electric charges q(A) = 1μc and q(B) = -2μc kept at a distance 0.5 meter apart.
We have to calculate much work is needed to move the charges apart and double the distance between them.
What s the formula to calculate the Potential Energy of a system of two charges (say 'q' and 'Q') separated by a distance 'r' ?The potential energy of the system of two charges separated by a distance is given by -
[tex]U = \frac{1}{4\pi\epsilon_{o} } \frac{qQ}{r}[/tex]
In order to solve this question, it is important to remember the work - energy theorem which states -
"The change in the energy of the body is equal to work done on it"
Hence, using this work -energy theorem in the question given to us we get -
[tex]U_{f} -U_{i} =W_{net}[/tex]
In our case -
[tex]U_{f} = \frac{1}{4\pi\epsilon_{o} } \frac{qQ}{2r}\\\\U_{i} = \frac{1}{4\pi\epsilon_{o} } \frac{qQ}{r}\\\\W=\frac{1}{4\pi\epsilon_{o} } \frac{qQ}{2r} - \frac{1}{4\pi\epsilon_{o} } \frac{qQ}{r}\\\\W = \frac{qQ}{4\pi\epsilon_{o}r} (\frac{1}{2} -1)\\\\W = 9\times 10^{9}\times \frac{1 \times 10^{-6} \times 2\times10^{-6} }{0.5} \times \frac{-1}{2}[/tex]
W = 0.018 joules
Hence, the total work done should be 0.018 joules.

The weight of air in a column 1-m2 in cross section that extends from sea level to the top of the atmosphere is?
From sea level to the top of the atmosphere, a column of air with a 1-m2 cross section weighs 101,000 N.
To find the answer we have to know about the pressure.
What is Pressure?The pressure at a point on a surface is the thrust acting per unit area around that point.[tex]Pressure, P=\frac{Thrust}{Area}=\frac{F}{A}[/tex]
A particular mass of air is contained in a column that rises from the ocean to the top of the atmosphere. Then,[tex]P=P_a=1.013*10^5 pascal[/tex]
Pa is the atmospheric pressure at the sea level.
By combining both the equations, we get the weight of air,[tex]\frac{F}{A}=P_a[/tex]
[tex]F=W=P_a*A=1.013*10^5*1=101300N[/tex]
Thus, we can conclude that, the weight of air in a column 1-m2 in cross section that extends from sea level to the top of the atmosphere is 101300N.

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.
