Answer:

heliocentric is when the earth and the other planets revolves around the sun.

Explanation:

I'm not sure about which one but I do know what heliocentric is.

Answer:

The mass of the object does not change by moving it to another place. ... At the center of the earth the net gravitational force is zero, so the weight will be zero, but its masses will remain same. Hence the mass at the centre of earth will be equl to 50 kg.

Explanation:

It's because the mass of the object doesn't change by moving it to next place.

3rd diagram

Explanation:

From the laws of reflection, we understood that the angle of incidence in equal to the angle of reflection.

For example, if a ray of light strikes a mirror at 60°, it reflected at the same angle (i.e 60°)

Considering the diagram given in the question above,

The ray of light strikes the mirror at 40°. Therefore, the light will be reflected with the same angle (i.e 40°)

Thus, the 3rd diagram gives the correct answer to the question.

Answer:

Just a little bit. You should not be on electronics all the time. I know some people that are so addicted to there electronics that they won't even hang out with people. If you are at the point where you think about things other than school, friends, and family...you should think about getting off of your electronics and go play with a neighborhood friend outside, or have a sleepover! Your whole life should not count on your phone, iPad, or your laptop.

Answer:

[tex]16.25^{\circ}[/tex]

Explanation:

R = Horizontal range of projectile = 75 m

v = Velocity of projectile = 37 m/s

g = Acceleration due to gravity = [tex]9.81\ \text{m/s}^2[/tex]

Horizontal range is given by

[tex]R=\dfrac{v^2\sin2\theta}{g}\\\Rightarrow \theta=\dfrac{\sin^{-1}\dfrac{Rg}{v^2}}{2}\\\Rightarrow \theta=\dfrac{\sin^{-1}\dfrac{75\times 9.81}{37^2}}{2}\\\Rightarrow \theta=16.25^{\circ}[/tex]

The angle at which the arrow is to be released is [tex]16.25^{\circ}[/tex].

Answer:

100 joules (J).

Explanation:

Converting Units - 36 km/h = 10 m/s

                               72 km/h = 20 m/s ( 1 km/h =  5/18 m/s)

Change in speed = 20 - 10 = 10 m/s

Applying the Work-Energy theorem,

[tex]Work done = \frac{1}{2} 2 (10)^2[/tex]

                 = 100 J.

Answer:

The acceleration of the runner is 0.25 m/s²

Explanation:

Given;

distance covered by the runner, d = 200 m

time of motion, t = 10 s

initial velocity of the runner, u = 0 (he started standing still)

final velocity of the runner, v = 36 km/h = 10 m/s

Therefore, to achieve the final speed of the runner, his acceleration is calculated as follows;

v² = u² + 2as

10² = 0 + (2 x 200)a

100 = 400a

a = 100/400

a = 0.25 m/s²

The acceleration of the runner is 0.25 m/s²

Answer:

Answer:

50 W

Explanation:

Power

For calculating power, we first need to know about the work done.

[tex] \bf \boxed{Work = Force \times displacement} [/tex]

Now, substituting values in the above formula;

Work = 100 × 5

= 500 Nm or 500 J

We know that,

[tex]\bf \boxed{Power=\dfrac{Work\:done}{Time\: taken}}[/tex]

Substituting values in above formula;

Power = 500/ 10

= 50 Nm/s or 50 W

Hence, power = 50 W .

Both nuclear fission and nuclear fusion produce energy from

matter

:D

Both nuclear fission and nuclear fusion produce energy from matter is the statement correctly comparing nuclear fission with nuclear fusion.

The process by which two or more tiny nuclei unite to generate a bigger nucleus is known as a nuclear fusion reaction.

The more energy it takes to liberate an electron from a smaller atom. This is referred to as binding energy.

As a result, when two little nuclei fuse together, there is more binding energy than when two big nuclei fuse together.

For example, the fusion of two hydrogen atoms produces more energy than the fusion of one helium atom, and surplus energy is expelled into space upon binding.

Both nuclear fission and nuclear fusion produce energy from matter is the statement correctly comparing nuclear fission with nuclear fusion.

Hence option D is correct.

Jupiter because of its strong gravitational force

Explanation:

Jupiter planet has the most important role in changing the direction of a comet's path. The correct option is C.

Gravity is a fundamental force in the universe that causes objects with mass or energy to attract one another. It is a force of attraction between any two objects in the universe that have mass. The force of gravity is directly proportional to the masses of the objects and inversely proportional to the distance between them.

Mathematically,

F=G×m1×m2/r²

The gravitational force is the force of attraction between two objects due to their masses. It is the force that causes objects to be drawn toward one another.

The strength of the gravitational force between two objects is determined by the mass of each object and the distance between them. The larger the mass of an object, the greater its gravitational force, and the closer two objects are, the greater their gravitational force.

Gravitational force is responsible for keeping the planets in orbit around the sun, for the tides on Earth, and for many other natural phenomena. The gravitational force is one of the four fundamental forces of nature, along with the strong nuclear force, the weak nuclear force, and the electromagnetic force.

Here in the question

Jupiter's strong gravitational force can significantly influence the trajectory of a comet, causing it to change direction or even collide with the planet. This is due to Jupiter's massive size, which creates a powerful gravitational pull that can affect objects within its vicinity. In fact, Jupiter is often referred to as the "vacuum cleaner of the solar system" because it has such a strong gravitational pull that it can attract and capture comets and asteroids.

Hence C. Jupiter because of its strong gravitational force, plays a most important role in changing the direction of a comet's path.
