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.

A brick is resting on a smooth wooden board that is at a 30° angle. What is one way to overcome the static friction that is hold

nata0808 [166]

Answer:

We apply force to move the brick.

Explanation:

Let me first of define a force .

A force is something applied to an object or thing to change it's internal or external state.

Now if a brick is resting on smooth wood inclined at 30° to the horizontal for us to overcome the friction which is also a force we have to apply a force greater than the gravity force acting on the body and then depending on the direction of the applied force the angle to apply it also.

Halley's comet moves about the Sun in an elliptical orbit, with its closest approach to the Sun being 0.59 A.U. and its greatest

Mrrafil [7]

Answer:

Explanation:

Given

Halley's closest distance from sun is $r_1=0.59\ A.U.$

Greatest distance is $r_2=35\ A.U.$

Comet's speed at closest approach is $v_1=47\ km/s$

As there is no external torque so angular momentum of comet about the sun is conserved

$L_1=L_2$

$mr_1^2\times \omega _1=mr_2^2\times \omega _2$

where $\omega =angular\ velocity$

This can be written as $\omega =\frac{v}{r}$

Therefore

$mr_1^2\times \frac{v_1}{r_1}=mr_2^2\times \frac{v_2}{r_2}$

$r_1\times v_1=r_2\times v_2$

$0.59\times 47=35\times v_2$

$v_2=0.79\ km/s$

consider a perfectly inelastic head-on collision between a small car and a large truck traveling at the same speed. Which vehicl

sergeinik [125]

Answer: The truck has a greater kinetic energy

Explanation:

The initial velocities of both the truck and car are the same. Likewise, the final velocity is the same. The change in kinetic energy is dependent only on mass. The truck has a greater mass, therefore, the change in its kinetic energy is greater.

What is the value of V^1?

Neporo4naja [7]

$\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}$

Actually Welcome to the Concept of the Current Electricity.

Since here, A potential divider is setup with two resisters in series, that is 3 ohm and 6 ohm.

As the voltage is always in directly proportional to the resistance,by ohm law,

V = IR, so the increase in Voltage will lead to increase in the resistance too.

hence,

for 6 ohm the voltage is 4 V, then for the 3 ohm it would be ,

V1 = (4/6)*3

==> V1 = 2 Volts,

==> hence the potential V1 = 2V
