Answer:

"0.758315 sec" is the appropriate choice.

Explanation:

The given values are:

Angular speed,

= 29 rad/s

or,

= [tex]\frac{29}{2 \pi} \ rps[/tex]

Tire rotates,

= 3.5 times

Now,

The time interval will be:

⇒  [tex]\Delta t=\frac{3.5}{\frac{29}{2 \pi} }[/tex]

⇒       [tex]=\frac{2 \pi\times 3.5}{29}[/tex]

⇒       [tex]=\frac{21.99}{29}[/tex]

⇒       [tex]=0.758315 \ sec[/tex]

Answer:

Bromine is heavier than air in terms of its atomic weight. Look at the periodic table bromine is lower than oxygen, nitrogen, etc. bromine in its gaseous phase will still float in air. This is due to the fact that gaseous bromine takes up a wide volume of space while having little mass.

The carbon cycle refers to the processes by which carbon in the biosphere is recycled. Photosynthesis sucks carbon dioxide out of the atmosphere, while cellular respiration releases it into the environment. Photosynthesis is the process by which solar energy reaches a plant and is converted into glucose.

How photosynthesis and cellular respiration are similar:

Photosynthesis is a method by which plants and other organisms transform light energy into chemical energy, which is then released to fuel the organism's metabolic activities through cellular respiration.

Answer:

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:

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 .

Answer:

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.

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

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.

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

Answer:

Forces, Gravity, Friction, Direction, Acceleration.

The answers for the fill-in-the-blanks would be  Force, gravity friction

direction and acceleration respectively.

It can be defined as the force by which a body attracts another body towards its center as the result of the gravitational pull of one body and another,

There are a few ways that moving objects are impacted. Pushes and pulls, or force, have an impact on how an object moves.

The force of gravity drags items toward the Earth.

Friction is a force that causes objects to move more slowly or even come to a stop.

It also applies to an item that is reversing course or slowing down. Since acceleration is a change in velocity, it can also be a change in speed or direction.

Thus, Force, gravity friction direction, and acceleration are the answers respectively.

Answer:

A)    I_total = 16 m, B)   I_total = 8 m,  C)   I_total = 8 m, D)  I_total = 8 m

Explanation:

The moment of inertia is a scalar quantity, therefore the total moment of inertia

          I_total = I₁ + I₂ + I₃ + I₄

the moment of inertia of a point mass with respect to an axis of rotation

         I = m r²

Let's apply this to our case

A) Rotation axis at the origin

     I₁ = m 0 = 0

for the second masses, we find the distance using the Pythagorean theorem

     r = [tex]\sqrt{2^2 + 2^2}[/tex]

     r = 2 √2

     I₂ = m (2 √2) ²

     I₂ = 8 m  

     I₃ = m 2² = 4 m

     I₄ = m 2² = 4 m

we substitute

     I_total = 0 + 8m + 4m + 4m

     I_total = 16 m

B) axis of rotation in the center of the square

let's find the distance to any mass

     r = [tex]\sqrt{1^2+ 1^2}[/tex]

     r = √2

     I₁ = m 2

     I₂ = m 2

     i₃ = m 3

     I₄ = m 4

we substitute

    I_total = 4 (2m)

    I_total = 8 m

C) axis of rotation is the x axis

       I₁ = 0

       I₂ = m 2² = 4 m

       I₃ = m 2² = 4 m

       I₄ = 0

       I_total = 8 m

D) axis of rotation is the y-axis

       I₁ = 0

       I₂ = 4m

       I₃ = 0

       I₄ = 4 m

       I_total = 8 m
