Answer:The reasons for the squirrels to fluoresce pink is still under investigation, but communication and camouflage are two top contenders for why this might be happening, the team has hypothesized. “They could be communicating with members of their own species by showing off their fluorescence to each other, or it might be a sort of mating display,”

Explanation:

I'm assuming that you are asking what is the elastic potential energy stored in the spring at the position stretched by 16.5 cm...

Since you know the spring constant k, 144 N/m and the spring stretch from the equilibrium position x, is 16.5 cm, or 0.165, you find the spring's potential energy from the equation PE = 12kx2, which equals 1.96 Joules, or kg * m2/s2 if you want SI units.

Answer:

Explanation:

1.) Students are going to conduct an experiment to study the effect of a net force applied to an object on the object’s motion. In each trial of the experiment, the students will apply a net force on the object. They also need to take two other measurements. What are the other quantities they should measure in each trial of the experiment?

ANSWER: mass and acceleration

2.) Use the data table to answer the question. It shows the acceleration of a body when a net force is applied to it.

An object has a starting position of 2 m, a starting velocity of 15 m/s, and is moving at a constant speed. Which option shows the final position of the object after 1 s?

ANSWER: 17 m

5.) The graph of an object's position over time is a horizontal line and y is not equal to 0. What must be true about the object's motion?

ANSWER: The velocity is zero.

hope this helps <3

As the graph shows, position over time is a horizontal line and y is not equal to 0 then the velocity is zero. Hence, option A is correct.

Acceleration is the rate at which the speed and orientation of a moving object change over time. When a spot or object moves faster or slower along a straight line, it is said to be accelerated. Even though the speed is constant, motion on a circle accelerates so because the direction is always shifting. Both by and to acceleration for all other types of motion.

It is a vector quantity because it has both magnitude and direction.

If the graph of an object's position over time is a horizontal line also y is not equal to 0 then it means that the velocity is zero, it cannot be constant or non-zero.

Therefore, it concludes that the velocity is zero and option A is correct.

The angular speed of the ball as it swings through its lowest point is 1.8 rad/s.

The given parameters;

radius of the circular path, r = 2.5 m

angle with the vertical, θ = 35⁰

The angular speed of the ball, as it swings through its lowest point is calculated as follows;

[tex]Tcos \theta = m\omega ^2 r\\\\mgcos \theta = m \omega ^2 r\\\\gcos \theta = \omega ^2 r\\\\\omega ^2 = \frac{gcos \theta }{r} \\\\\omega = \sqrt{\frac{gcos \theta }{r} } \\\\\omega = \sqrt{\frac{9.8 \times cos (35) }{2.5} } \\\\\omega = 1.8 \ rad/s[/tex]

Thus, the angular speed of the ball as it swings through its lowest point is 1.8 rad/s.

How is hydrogen obtained and separated from other nearby substances?

photoelectrolysis, a photoelectrochemical cell submerged in water uses sunlight to separate the water into hydrogen and oxygen bubbles. In the thermochemical cycle, water is heated to 800 to 1,000 °C, with the molecule. splitting to release hydrogen. The main drawback of this method is that it requires nuclear power

How is Hydrogen used?

Hydrogen can be used in fuel cells to generate electricity, or power and heat. Today, hydrogen is most commonly used in petroleum refining and fertilizer production, while transportation and utilities are emerging markets

What products are made from Hydrogen?

Hydrogen is a very useful element. It is used to make ammonia for fertilizers, refining metals, and methanol for making artificial material like plastics. Hydrogen is also used as a rocket fuel where liquid hydrogen is combined with liquid oxygen to produce a powerful explosion.

Any environmental concerns about the use of Hydrogen?

Emissions of hydrogen lead to increased burdens of methane and ozone and hence to an increase in global warming. Therefore, hydrogen can be considered as an indirect greenhouse gas with the potential to increase global warming.

Explanation:

The bullet travels for a time of

180 m/800 m/s = 0.225 s

Assuming the original velocity was horizontal

h = ½(-9.8)0.225² = 0.25 m

The bullet will accelerate as it descends at the same rate  that it slowed down as it rose, since gravity is constant (i.e., it doesn't vary). It will therefore be travelling at the same speed as when it was first fired from the gun when it reaches the bottom.

As soon as the gun is discharged, the propellant in the barrel expands, speeding up the bullet. The bullet is no longer propelled once it exits the muzzle since the gasses can now escape outside and the bullet is now encountering air resistance. Therefore, the muzzle velocity at the barrel's exit is the highest it can be.

A bullet thrown straight up on Earth would be able to reach a maximum height of around three kilometres (about 10,000 feet (ca. 3 km)), assuming there is no wind, before falling back to Earth.

Therefore, The bullet travels for a time of 180 m/800 m/s = 0.225 s assuming the original velocity was horizontal h = ½(-9.8)0.225² = 0.25 m.

By applying Newton's Second Law of Motion, the force acting on the mass is 45.0 Newton.

Given the following data:

To determine the force acting on the mass in Newton, we would apply Newton's Second Law of Motion:

Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on the physical object or body, and inversely proportional to its mass.

Mathematically, Newton's Second Law of Motion is given by this formula;

[tex]Force = mass \times acceleration[/tex]

Substituting the given parameters into the formula, we have;

[tex]Force = 15.0 \times 3.0[/tex]

Force = 45.0 Newton
