The magnetic force is [tex]F_{B}[/tex] = B ( B.L.v/R). L = [tex]\\\frac{B^{2} L^{2}v^{} }{R}[/tex]and the terminal velocity is 0.6487 m/s.

One of the four fundamental forces of nature, the electromagnetic force, results in the magnetic force, which is brought about by the motion of charges. When two charge-containing objects move in the same direction, a magnetic attraction pulls them together.

Calculation:

(a) Magnetic force, on the slide wire is Fb = B.I.L

the magnitude of induced emf from faradays law ε = dΦ/dt

= d ×( B.A)/ dt

= B × (dA/dt)

= B × (d(Lx)/dt)

=B × L × (d (x)/dt)

= B × L×v

But the induced current is I = ε/R

= BLv/R

Now, the magnetic force is [tex]F_{B}[/tex] = B ( B.L.v/R).L

= [tex]\\\frac{B^{2} L^{2}v^{} }{R}[/tex]

if the magnetic force is equal to the weight of the wire.

v = (mg. R)/ B² × L²

(b) terminal velocity = 9 *[tex]10^{-3}[/tex]* 9.8 * 0.10 / [tex]0.53^{2}[/tex] * [tex]0.22^{2}[/tex] = 0.6487 m/s.

Hence, the magnetic force is [tex]F_{B}[/tex] = B ( B.L.v/R). L = [tex]\\\frac{B^{2} L^{2}v^{} }{R}[/tex]and the terminal velocity is 0.6487 m/s.

The space probe must be at a distance of 258774.9441 m from the earth.

Let us assume, x is the distance of probe from the earth

y is the distance of probe from the sun

Distance between the earth and the sun = x + y = 149.6 * 10⁶ m

G = Gravitational constant

Ms = Mass of the sun = 1.989* 10³⁰ kg

Me = Mass of the earth = 5.972 * 10²⁴ kg

Now, let us put the values in the below equation

(G * Ms * m)/ x² = (G * Me * m)/ y²

Ms / x² = Me / y²

x = √(Ms * y²/ Me) = √( 1.989* 10³⁰y²/ 5.972 * 10²⁴ ) = 577.10852y

x + y = 149.6 * 10⁶

577.10852 y + y = 149.6 * 10⁶

578.10852 y = 149.6 * 10⁶

y = (149.6 * 10⁶ )/ 578.10852 = 258774.9441 m

The amount of work which Sam does need to stop the boat is 784Joule  if boat mass  is 800kg and boat drift in 1.4m/sec.

We know that according to work-energy theorem, change in kinetic energy of the body from one speed to another is equivalent to amount of work done by all forces acting on the body.

So, here we can see that final speed of boat is =0m/sec since Sam need to stop it.

Initial speed of boat is 1.4m/sec.

Also, we know that kinetic energy is given by the below formula:

Kinetic energy=(1/2)mv²

where m is the mass of the body

and v is the speed of the body

Now, from work energy theorem, we get

=>W=(1/2)m[tex]v^2_2[/tex] - (1/2)m[tex]v^2_1[/tex]

=>W=0-(1/2)×800×(1.4)²

=>W= - 400× 1.4 × 1.4

=>W = -400×1.96

=>W= -784Joule

Here negative sign denotes work has to done against the original motion of boat.

Hence, amount of work needs to be done by Sam is 784Joule.

Explanation:

The structure of a typical vertebra includes Pedicle, body, vertebral arch, etc. These are discussed in the section below.

Pedicle: The sides of the vertebral arch are formed by a pair of short, thick bony structures that protrude from the back of the vertebral body.

The thick, anterior section of the vertebra known as the "body" is what supports and supports the weight of the vertebral column.

Lamina: A pair of flat plates that combine to create the back of the vertebral arch and extend posteriorly from the pedicles.

The vertebral arch, which is made up of the pedicles and laminae, forms the posterior opening of the vertebra and surrounds and shields the spinal cord.

Articular facet: The superior and inferior portions of the vertebral arch's smooth, flat surfaces that form the facet joints when they articulate with the surrounding vertebrae.

The spinal cord goes through the vertebral foramen, which is the vertebral arch's main aperture.

Transverse process: Laterally extending bony projections from the sides of the vertebral arch that act as points of attachment for ligaments and muscles.

Both are reverse square regulations, where power is conversely relative to the square of the distance between the bodies.

When a vehicle travels around a corner or curve,  the outside wheel must travel the greatest distance, it is based on the car differential.

When a car turns a corner, one wheel is on the "inside" of a turning arc, and the other wheel is on the "exterior." Thus, the exterior wheel has got to turn speedier than the interior one in order to cover the greater separation within the same sum of time. In this way, since the two wheels are not driven at the same speed, a differential is essential. A car differential is set midway between the driving wheels, on either the front, raise, or both axes, depending on the wheel-drive car. In rear-wheel drive cars, the differential changes over the rotational movement of the transmission shaft which lies parallel to the car’s movement to the rotational movement of the half-shafts (on the closes of which are the wheels), which lie opposite to the car’s movement.

Answer: It reduces the activation energy.

Explanation:

A catalyst is a material that, without being consumed by the process, speeds up a chemical reaction or decreases the temperature or pressure required to initiate one. The addition of a catalyst to a reaction is known as catalysis.

The bonds holding together the atoms in molecules are ruptured, altered, and repaired during a chemical reaction, recombining the atoms to form new molecules. By decreasing the activation energy, the energy hurdle that must be cleared for a chemical reaction to take place, catalysts improve the efficiency of this process. As a result, catalysts facilitate the formation of chemical bonds between atoms to create novel combinations and new compounds. Chemical processes are accelerated and become more energy-efficient when catalysts are used.
