6 0

The correct answer to the question is Fusion i.e the process of combining two small nuclei into one nucleus of larger mass is called fusion.

EXPLANATION:

Before answering this question, first we have to understand nuclear fission and nuclear fusion.

Nuclear fission is the thermo nuclear process in which a heavy unstable nucleus will split into two light stable nuclei with the release of energy.

For instance, the splitting of Uranium-235 to Krypton-92 and Barium-141.

Nuclear fusion is just the opposite process of nuclear fission. It is the thermo nuclear process in which two light unstable nuclei will combine with each other at a high temperature equal to the temperature of sun to form a large stable nuclei with the release of energy.

For instance, we may take hydrogen bomb i.e the energy formation in stars. Here, four hydrogen nuclei will combine with each other form a helium nuclei with the release of huge amount of energy.

Hence, the correct answer to the question is nuclear fusion.

An object of mass m travels along the parabola yequalsx squared with a constant speed of 5 units/sec. What is the force on the

Dmitriy789 [7]

Explanation:

The object is moving along the parabola y = x² and is at the point (√2, 2). Because the object is changing directions, it has a centripetal acceleration towards the center of the circle of curvature.

First, we need to find the radius of curvature. This is given by the equation:

R = [1 + (y')²]^(³/₂) / |y"|

y' = 2x and y" = 2:

R = [1 + (2x)²]^(³/₂) / |2|

R = (1 + 4x²)^(³/₂) / 2

At x = √2:

R = (1 + 4(√2)²)^(³/₂) / 2

R = (9)^(³/₂) / 2

R = 27 / 2

R = 13.5

So the centripetal force is:

F = m v² / r

F = m (5)² / 13.5

F = 1.85 m

Select all the correct answers. a leaf falls through the air, floating as it falls. air resistance is visibly affecting the leaf

musickatia [10]

Surface area and Mass

When a leaf falls, it is being accelerated by gravity to the ground but opposed by air resistance also the drag. The net force on a leaf will therefore be calculated by subtracting its weight of the leaf from its drag.

<h3>What is Air resistance ?</h3>

Air exerts a force known as air resistance. When an object is travelling through the air, the force works in the opposite direction.

While a sports vehicle with a streamlined design will encounter reduced air resistance and experience less drag, the automobile will be able to move more quickly than a truck with a flat front.
The speed, area, and shape of the object passing through the air all affect air resistance. Air density and resistance are affected by altitude, temperature, and humidity. The resistance increases with speed and area, respectively.

The equations below show the total amount of water in gallons, y, that has flowed through two different types of shower heads af

Dennis_Churaev [7]

Answer:

The correct option is option (B)

Explanation:

Given that,

The equation below show the total amount of water in gallons, y that has flowed through two different types of showers heads after x minute.

Type A: y =1.25 x

Type B: y= 2.50 x

So,

The amount of water per minute is $=\frac{\textrm{The amount of water}}{\textrm{Time}}$

For type A

y =1.25 x

$\Rightarrow \frac{y}{x}=1.25$

For type B

y =2.50 x

$\Rightarrow \frac{y}{x}=2.50$

$\Rightarrow \frac{y}{x}=2\times 1.25$

The amount of water flowed through Type B is twice that flowed trough type A per minute.

An elevator filled with passengers has a mass of 1603 kg. (a) The elevator accelerates upward from rest at a rate of 1.20 m/s2 f

Galina-37 [17]

Answer:

T = 17649.03 N = 17.65 KN

Explanation:

The tension in the cable must be equal to the apparent weight of the passenger. For upward acceleration:

$T = W_A = m(g+a)\\$

where,

T = Tension in cable = ?

$W_A$ = Apparent weight

m = mass = 1603 kg

g = acceleration due to gravity = 9.81 m/s²

a = acceleration of elevator = 1.2 m/s²

Therefore,

$T = (1603\ kg)(9.81\ m/s^2+1.2\ m/s^2)\\\\$

Late one night on a highway, a car speeds by you and fadesinto the distance. Under these conditions the pupils of your eyes(aver

Andrews [41]

Answer:

10432.19076 m

Explanation:

$\lambda$ = Wavelength = 660 nm

d = Diameter of pupils = 6 mm

s = Distance between lights = 1.4 m

L = Distance from observer

From Rayleigh's criteria we have

$1.22\lambda=dsin\theta$

As $\theta$ is small $sin\theta=\dfrac{s}{L}$

So, the equation becomes

$1.22\lambda=d\dfrac{s}{L}\\\Rightarrow L=\dfrac{ds}{1.22\lambda}\\\Rightarrow L=\dfrac{6\times 10^{-3}\times 1.4}{1.22\times 660\times 10^{-9}}\\\Rightarrow L=10432.19076\ m$

The car is 10432.19076 m from me
