Answer:
Nuclear Power Plant
Explanation:
Heat produced during nuclear fission to heat water. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy. Fission takes place inside the reactor of a nuclear power plant. At the center of the reactor is the core, which contains uranium fuel.
2. A digital camera records each image as 8 megapixels, with each pixel transferring 14 bits of information. What is the minimum capacity for a memory card which could hold 120 images?
Given what we know, we can confirm that due to its relatively low image quality, any memory card with at least one MB will be sufficient to hold the 120 images taken.
Why is one MB enough?The photos are taken at 8 megapixels, with each one occupying 14 bits of information. A megabit consists of one million bits of potential storage. Therefore, the 120 pictures will occupy roughly 1% of the available storage of a 1 MB memory card.
Therefore, we can confirm that due to its relatively low image quality, any memory card with at least one MB will be sufficient to hold the 120 images taken.

FIGURE 4.1 shows a rectangular wire loop 0.3 m x 0.2 m moving horizontally to the right at 12 ms -1 in a uniform magnetic field of 0.8 T. The induced current in the wire is 3 A.
(i) Determine the resistance of the wire loop
(ii) Determine the direction of the induced current. Explain how you determine the direction of the induced current.
[tex]\underline{\underline{\large\bf{Solution:-}}}\\[/tex]
(I) Emf developed,E in the loop is given as:
[tex]\begin{gathered}\\\implies\quad \sf E = BLv \\\end{gathered} [/tex]
[tex]\begin{gathered}\\\implies\quad \sf E = 0.8 \times 0.3 \times 12 \\\end{gathered} [/tex]

where
R = resistanceE = Induced EMFI = Current[tex]\begin{gathered}\\\implies\quad \sf R = \frac{2.88}{3} \\\end{gathered} [/tex]

(ii) The direction of current induced is from P to Q which is given by B × V vector . It may also be explained by Lenz law. Since magnetic field is from S to N . The fingers of the right hand are placed around the wire so that the curling of fingers will show the direction of the magnetic field produced by the wire then the thumb points in the direction of current flow which is from P to Q.
In a footrace between two runners, is it possible for the second-place finisher have a greater speed
at the finish line than the winner?
Answer:
no
Explanation:
this may be wrong, but i would assume no because they have to cover the same distance therefore the faster runner would cross the finish line first.
A 4-kg box is pushed against a flat 1 point
surface with a force of 100 N for 5
meters. The work done on the box is
Answer:
wd = F * D
wd = 100 * 5
wd = 500
The work done on the box is 500 Joules.
What is work?
When an object is moved over a distance by an external force, at least a portion of which is applied in the direction of the displacement, it is said to have done "work" in physics. By multiplying the length of the path by the component of the force acting along the path, work can be calculated if the force is constant.
As work is a scalar quantity, it can be defined only by magnitude, it has no direction. SI unit of work is Joule and CGS unit of work is erg.
Given parameters:
Mass of the box: m = 4 kg.
Force applied on the box: F = 100 N.
Displacement of the box: d = 5 meters.
Hence, the work done on the box is = applied force × displacement
= 100 N × 5 meters
= 500 Joules.

Answer:
Twice as much
Explanation:
D 5-7 Be the only person I know of is the Book with all men and men and people experience the first of the wisdom and
The acceleration produced will be one-half as much.
What is acceleration?Acceleration is rate of change of velocity with time. Due to having both direction and magnitude, it is a vector quantity. SI unit of acceleration is meter/second² (m/s²).
From Newton's 2nd law of motion; it can be written that:
Force = mass × acceleration
acceleration = force/mass.
Now, according to the question, an unbalanced force of 2 newtons applied to a given mass produces an acceleration.
So, when an unbalanced force of 1 newton is applied to the same mass, the force applied on the object becomes half.
Hence, from the equation, the acceleration produced will be one-half as much.

A spring has a natural length of 28.0 cm. If a 23.0-N force is required to keep it stretched to a length of 36.0 cm, how much work W is required to stretch it from 28.0 cm to 32.0 cm
Answer:
0.23 J
Explanation:
k*(36 - 28) = 23
so k = 23/8 N/cm
W = k(32 - 28)²/2 = 23/8 * 4²/2 = 23 N-cm = 0.23 J
