Which type of electromagnetic wave has more energy than ultraviolet waves
have?
O A. Visible light
B. Infrared
O C. X-rays
O D. Microwaves

Answer:

After refraction at two parallel faces of a glass slab, a ray of light emerges in a direction parallel to the direction of incidence of white light on the slab. As rays of all colours emerge in the same direction (of incidence of white light), hence there is no dispersion, but only lateral displacement.

Answer:

When water freezes to form ice, the molecules would be vibrating in place rather than moving round. It is a result of a decrease in the kinetic energy of the molecules of water. It is said that the temperature and the kinetic energy of the molecules is directly proportional which means that when temperature is increased, the kinetic energy of the molecules would increase as well making the molecules move around. However for this case, when we day the system is cooled then it means the temperature is decreased which would result to the decrease of the kinetic energy of the molecules.

Rita runs faster

Explanation:

To obtain the answer to the question given, we determine the speed of Rita. This can be obtained as follow:

Distance = 1.6 km

Time = 15 mins

Speed =?

Next, we shall convert 15 mins to hour. This can be obtained as follow:

60 mins = 1 h

Therefore,

15 mins = 15 mins × 1 h / 60 mins

15 mins = 0.25 h

Thus, 15 mins is equivalent to 0.25 h.

Finally, we shall determine speed of Rita as follow:

Distance = 1.6 km

Time = 0.25 h

Speed =?

Speed = distance / time

Speed = 1.6 / 0.25

Speed = 6.4 Km/h

Thus Rita's speed is 6.4 Km/h

Comparing the speed of Rahul and Rita

Rahul's speed = 4.5 km/h

Rita's speed = 6.4 Km/h

We can see that Rita's speed is greater than Rahul's speed. This simply indicates that Rita runs faster than Rahul.

Explanation:

Location A represents the Caribbean region which is known for tourist attractions such as nice beaches. It is also known however, for devastating hurricanes.

Apart from mostly being islands, which puts them at risk of being in Hurricane paths, the Caribbean is warm and the air is moist. Hurricanes derive energy from these two things which is why Hurricanes attack the Caribbean rather frequently.

3. Large butterfly in flight, flying through the air?

Explanation:

Momentum is simply defined as the quantity of motion a body possess. It is mathematically given as;

 Momentum  = mass x velocity

The larger the mass, the larger the momentum and also the velocity

Since the large butterfly is in flight, it has the largest velocity.

A sleeping bear and resting caterpillar have no momentum because their velocity is 0

c. Developing new technologies designed to see farther into space

than before

The universe is everything including all of space, and all the matter and energy that space contains. Also it includes time itself and, of course, it includes us.

What began as a sequence one-upmanship in space-related technological advancements between the U.S. and the Soviet Union would spawn incredible progress observed in innovation to this day. The battle for dominance not only as a global superpower, but a space power, led the United States and the Soviet Union to race to put men in space and eventually on the moon.

The launch of the Soviet satellite Sputnik on Oct. 4, 1957, would place pressure on the U.S. to design technologies crafted for space exploration. This, in turn, spurred a series of innovations in technology that would have far reaching impacts beyond space.

These technologies can be seen as developments in modern healthcare, construction, and transportation. Relevant examples include medical imaging techniques,  artificial limbs, water filtration systems, solar panels, firefighting equipment, shock absorbers, air purifiers, home insulation, weather resistant airplanes, infrared thermometers, and countless other vital inventions.

While all these creations help sustain essential aspects of modern life, we carry one of the largest technological advancements from the space race in our pockets today.

Therefore, Developing new technologies designed to see farther into space than before lead scientists to develop new explanations about the universe.

Answer:

W = 9.8 J

Explanation:

Given that,

Mass of the book, m = 2kg

A student lifts it from the floor to a desk that is 0.5 meters high.

We need to find work done by the student. The work done in lifting the book is given by :

W = mgh

Put all the values,

W = 2 kg × 9.8 m/s² × 0.5 m

W = 9.8 J

So, the required work done is 9.8 J.

Answer:

In physics, equations of motion are equations that describe the behavior of a physical system in terms of its motion as a function of time.[1] More specifically, the equations of motion describe the behaviour of a physical system as a set of mathematical functions in terms of dynamic variables. These variables are usually spatial coordinates and time, but may include momentum components. The most general choice are generalized coordinates which can be any convenient variables characteristic of the physical system.[2] The functions are defined in a Euclidean space in classical mechanics, but are replaced by curved spaces in relativity. If the dynamics of a system is known, the equations are the solutions for the differential equations describing the motion of the dynamics.

Answer:

the buckets mass is 346g if im not mistaken

Explanation:

Mass of the bucket is 1.48kg

Centripetal force f=25N

Radius r=1.2m

speed v=4.5m/s

By the formula of centripetal force,

Centripetal force = mass x velocity2 / radius on putting the values

25= {m*4.5*4.5}{1.2}

m={250*12}{45*45}

  ={40}{27}

  =1.48kg

The mass of the bucket is 1.48kg.

Answer:

Acceleration = 5m/s² Southeast

Explanation:

Given the following data;

Final velocity = 10 m/s

Time = 2secs

To find acceleration;

In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.

This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.

Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.

Mathematically, acceleration is given by the equation;

[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]

[tex]a = \frac{v - u}{t}[/tex]

Where,

a is acceleration measured in [tex]ms^{-2}[/tex]

v and u is final and initial velocity respectively, measured in [tex]ms^{-1}[/tex]

t is time measured in seconds.

We know that Initial velocity = 0m/s

Substituting into the equation, we have;

[tex]a = \frac{10 - 0}{2}[/tex]

[tex]a = \frac{10}{2}[/tex]

Acceleration = 5m/s² Southeast.
