Answer:

Colors!

Explanation:

"Visible light waves are the only electromagnetic waves we can see. We see these waves as the colours of the rainbow. Each colour has a different wavelength. Red has the longest wavelength, and violet has the shortest wavelength."

Answer:liquid

Explanation:

[Questoin 1] Volume

     "Charles's law is an experimental gas law that describes how gases tend to expand when heated." Expand = volume, so this answer is correct

[Question 2] b) move faster

     An increase in heat is an increase in energy, which is an increase in particle movement. This means that b is correct, because the particles will be moving faster

[Question 3] a) Celsius

     Charles' Law uses Celsius, so when doing Charles' Law problems you should use Celsius, aka °C

Weight loss for a fat body does not make a sense of healthy habits. The scale should just be one method of monitoring her overall health.

Healthy habits include good food habits, regular exercising, personal hygiene and positive mind. These all factors affecting our health and it not just our weight.

Body weight can be controlled up to a limit by healthy habits and and controlled food. However, the some people might have a nature of fatty body or skelt irrespective of their habits. In such cases people no need to worry on their health by just looking on their weight.

Weight scale should just be one method of monitoring  the overall health. By losing weight or gaining weight we cant said to be in good health. Therefore, option A be the best response to Shondra.

Hi there!

(A)

We can solve for acceleration using the following equation:

Δd = vit + 1/2at²

The shuttle lifts-off from rest, so:

Δd = 1/2at²

Rearrange to solve for 'd':

2Δd/t² = a

2(350)/(3.5²) = 57.14 m/s²

(B)

Now, we can use this equation to solve for final velocity:

vf = vi + at

vf = at

vf = 57.14 × 3.5 = 200 m/s

(C)

Now, we can use the following equation to solve for displacement:

Δd = vt

Δd/v = t

350/200 = 1.75 sec

Answer:

A. Energy

Explanation:

In general, the word energy refers to a concept that can be paraphrased as "the potential for causing changes", and therefore one can say that energy is the cause of any change. The most common definition of energy is the work that a certain force (gravitational, electromagnetic, etc) can do..I really hope this helps.

The angular speed of the passenger in radians per second is 0.126 rad/s.

The given parameters;

The angular speed of the passenger in radians per second is calculated as follows;

[tex]\omega = \frac{2\pi N}{T} \\\\\omega = \frac{2\pi \times 12 \ rad}{600 \ s} \\\\\omega = 0.126 \ rad/s[/tex]

Thus, the angular speed of the passenger in radians per second is 0.126 rad/s.

Answer: 17 m/s,

Explanation:

Emily throws the ball at 30 degree below the horizontal

so here the speed is 14 m/s and hence we will find its horizontal and vertical components

v_x = 14 cos30 = 12.12 m/sv

x

=14cos30=12.12m/s

v_y = 14 sin30 = 7 m/sv

y

=14sin30=7m/s

vertical distance between them

\delta y = 4 mδy=4m

now we will use kinematics in order to find the time taken by the ball to reach at Allison

\delat y = v_y *t + \frac{1}{2} at^2\delaty=v

y

∗t+

at

here acceleration is due to gravity

a = 9.8 m/s^2a=9.8m/s

now we will have

4 = 7 * t + \frac{1}{2}*9.8 * t^24=7∗t+

∗9.8∗t

now solving above quadratic equation we have

t = 0.44 st=0.44s

now in order to find the horizontal distance where ball will fall is given as

d = v_x * td=v

x

∗t

here it shows that horizontal motion is uniform motion and it is not accelerated so we can use distance = speed * time

d = 12.12 * 0.44 = 5.33 md=12.12∗0.44=5.33m

The total energy could then be written as;  Etotal = ME + Ethermal

The term energy is the refers to the ability to do work. We know that according to the first law of thermodynamics, energy is neither created nor destroyed but can be converted from one form to another.

The total energy of the system must then be the sum of all the energies that are in the system. In this case, the system has both mechanical and thermal energy.

The total energy could then be written as;  Etotal = ME + Ethermal

Explanation:

Hope this helped, nya~ :3

Answer:

S1 = V1 t + 1/2 g t^2      distance traveled by ball dropped

S1 = 1/2 g t^2        since ball is dropped and V1 = zero

S2 = -1/2 g t^2 + V2 t        height to which ball 2 rises in time t

S1 + S2 = V2 t     both balls at same height after time t

t = S / V2 = 21.3 / 31.2 = .683 sec

Check:

S1 = 1/2 g t^2 = 9.8 / 2 * .683^2 = 2.29 m

S2 = 31.2 * .683 - 9.8/2 * .683^2 = 19 m

Total distance traveled = 2.29 + 19 = 21.3 m

Okay so, You have 3 numbers in this equation, 170, 2, and 70.

Divide 170 by 2= 85

Add 85 + 70= 155

Now divide 155 by 2= 77, R1 = 77 1/2. You can turn 77 1/2 to 77.5

Find the acceleration:

v² - u² = 2ax

(v = final velocity, u = initial velocity, a = acceleration, x = displacement)

(82.0 m/s)² - 0² = 2 a (0.400 m)

a = (82.0 m/s)² / (2 (0.400 m))

a = 8405 m/s²

Find the time:

x = ut + 1/2 at²

(t = time)

0.400 m = 0 + 1/2 (8405 m/s²) t²

t² = (0.400 m) / (1/2 (8405 m/s²))

t = √((0.400 m) / (1/2 (8405 m/s²)))

t ≈ 0.00976 s
