describe the motion represented by a horizontal line on a distance ?

Once the engine has fired, the rocket's final speed is 29.16 m/s whose impulse is of 3.5 kgm/s and mass is 120g.

We match the momentum data to the amount of movement using the momentum and amount of movement concept to determine the speed.

Given the mass of rocket (m) = 120g = 0.12kg

Impulse of engine (I) = 3.5kg-m/s

Let the final speed of rocket = v

We know that Impulse is equal force multiplied by time. I = F x t

Then, impulse can also be calculated mass multiplied by velocity according to momentum of rocket. So, I = m x v

Then, m x v = I

Here we neglect the weight force during the brief engine firing as well as the change in mass that occurs.

v = 3.5/0.12 = 29.16m/s

Hence once the engine has fired, the rocket's final speed is 29.16 m/s.

The organism represented below is a multicellular, heterotrophic and completely aquatic organism which carries out photosynthesis and needs oxygen. Thus, the correct option is C.

Hydra belongs to the phylum Cnidaria of the Animal kingdom, it is a fresh water form. These organisms are sessile, free swimming invertebrates. Cnidarians exhibit a blind sac body plan and these are radially symmetrical. These organisms are more advanced than that of sponges in having true tissues in their body. They are, however, also acoelomate.

The organism which is shown here lives in water and is completely aquatic which means it does goes on the land for a while. It is a heterotrophic organism as it does not make its food through the help of the process known as photosynthesis.

In this case, this organism is not a plant. This organism is a multicellular organism, which feeds on the plants or other organism present in water. This organism reproduces through asexual mode of reproduction and is therefore definitely a consumer.

Therefore, the correct option is C.

The ball moving for 3.4m distance for 8.5 secs time has greater velocity than the fish moving for 6.2m distance for 36 secs time.

Kinematics is the branch of physics dealing with the motion of an object, without regard to the cause of this motion. It includes distance and displacement, speed and velocity, time, and acceleration. The same quantities are used in linear as well as angular or rotational motion.

We have two objects given to us, a ball and a fish. First, the ball, the displacement,d₁ the ball travels=3.4m, the time t₁ taken by the ball =8.5s.

Its velocity, v₁=d₁/t₁ , v₁=3.4m/8.5s, v₁=0.4m/s. Secondly, for the fish, the displacement that the fish travels, d₂ =6.2 m, the time taken by the fish,t₂ =0.6 minutes =0.6×60=36 seconds.

 The time taken by the fish is converted from minutes to seconds, as  1 minute = 60 seconds. The velocity of the fish is v₂=d₂/t₂, v₂=6.2m/36s=0.172m/s.

So we can conclude that the ball has greater velocity(v₁=0.4m/s) than the fish ( v₂=0.172m/s).

One possible combination of the new planet's mass and radius, in terms of the mass of Earth and its radius, is three times Earth's mass and twice its radius.

The design of the rotating spacecraft described in the question utilizes the principle of centrifugal force to mimic the surface gravity of different planets. The outer ring, with a radius of 30 meters, is designed to mimic the surface gravity of Earth (approximately 9.80 m/s²). The inner ring, on the other hand, is designed to help the astronauts become accustomed to the surface gravity of a new planet (7.35 m/s²).

In order to achieve this, the new planet must have a mass that is 3 times that of Earth and a radius that is twice that of Earth. This is because centrifugal force is proportional to the mass of the object and the square of its radius, so a larger mass and larger radius would be required to create the desired surface gravity.

All physical things with mass are attracted by the gravitational force, which can be thought of as an attractive force. It is by far the weakest known natural force.

Objects with mass are drawn toward one another by gravity, also known as the gravitational force. Gravitational pull from Earth is a topic that we frequently consider. Your body is held firmly in place by this force. However, every mass-bearing item pulls everything else with mass toward it through gravity.

It is possible to think of the gravitational force as an attracting force that pulls all mass-containing physical objects together. It is the known natural force with the lowest strength.

The force of attraction between any two bodies is directly inversely correlated to the square of the distance between them and is directly inversely correlated to the product of their masses, according to Newton's universal law of gravitation.

Explanation: the force of the door on your hand is not the same as just the force of your hand

The frictional force if greater than the applied force, then the movement of the block gets resisted against the applied force and the block does not undergo any displacement.

Force is an external agent actin on an object to change its motion or to deform it. There are various kinds of forces such as frictional force, gravitational force, magnetic force etc.

If two or more same or different forces acting on an object from the same side they will add up in magnitude. If two forces with same magnitude are acting from opposite direction of the object, then they will cancel each other and the net force will become zero. This situation is called the balanced force.

If two unequal force acts from opposite direction, the net force is the substracted value of their magnitudes and the situation is called unbalanced force.

Here, the frictional force if greater than the applied force, then the movement of the block gets resisted against the applied force and the block does not undergo any displacement.

Astronomy differs from lab sciences like chemistry or biology in that it is an observational science.

This means that astronomers primarily gather data through the use of telescopes and other instruments to observe objects in space, rather than performing experiments in a laboratory setting.

One of the main challenges in astronomy is that the objects being studied are often extremely distant and difficult to observe directly.

However, astronomers have developed a variety of techniques to study these objects, such as analyzing the electromagnetic radiation they emit, studying their motions and positions, and using computer simulations to model their behavior.

Astronomers can be confident in their understanding of remote objects by using multiple methods to study them and by comparing their results to existing theories and models.

They also use statistical analysis to quantify the uncertainty of their measurements and observations.

In conclusion, while astronomy shares some similarities with lab sciences, it differs in that it is an observational science and the objects being studied are remote.

Astronomers overcome these challenges by using a variety of techniques and by cross-checking their results with existing theories and models.

The total momentum is 300,000 kg·m/s.

Momentum is a concept of physics that states that an object in motion will remain in motion unless it is acted on by an outside force. It is often used to describe the speed and direction of an object's movement. Momentum is also used in the field of finance to refer to the speed and direction of an asset's price movement. The concept is based on the idea that an asset that has been moving in one direction will tend to continue in that direction unless something changes. Momentum investing is a strategy that attempts to capitalize on this phenomenon by buying assets that are rising in price, and selling assets that are declining in price.

The total momentum after the collision is the sum of the momentum of Train A and Train B before the collision. The momentum of each train is calculated by multiplying its mass (30,000 kg) by its velocity (10 m/s for Train A and 5 m/s for Train B). Therefore, the total momentum is (30,000 kg x 10 m/s) + (30,000 kg x 5 m/s) = 300,000 kg·m/s.

When it is maximum, acceleration is zero. The rate at which velocity changes is called acceleration. Acceleration often indicates a change in speed, but not necessarily.

The rate at which an object's velocity with respect to time changes is referred to as acceleration in mechanics. It is a vector quantity to accelerate (in that they have magnitude and direction). The direction of the net force applied on an item determines the direction of its acceleration. According to Newton's Second Law, an object's acceleration is the result of two factors working together: the object's mass, which varies depending on the materials it is made of, and the net balance of all external forces acting on it. The magnitude of an object's acceleration is inversely proportional to the object's mass.
