For a reaction to occur what must happen to the energy in order to break the chemical bond

Answer:

Frequency and wavelength are inversely related.

Explanation:

Frequency and wavelength have an inverse relationship because if one thing goes up another goes down. For example, if frequency goes up, the wavelength goes down and vice versa.

Answer:

The relationship between wavelength and frequency is that the frequency of a wave multiplied by its wavelength gives the speed of the wave.

Explanation:

Frequency and wavelength are related terms also, used to describe electromagnetic radiation or light. One simple equation is used to convert between them: frequency x wavelength = speed of light. λ v = c, when λ is wavelength, v is frequency, and c is the speed of light.

Answer:

Choice C is not equivalent to 2.50 miles.

Explanation:

The given data is now converted into feet, inches, kilometers, yards and centimeters:

mi - ft

[tex]x = (2.50\,mi)\cdot \left(5280\,\frac{ft}{mi} \right)[/tex]

[tex]x = 13200\,ft[/tex]

[tex]x = 1.320\times 10^{4}\,ft[/tex] (Choice A)

mi - in

[tex]x = (2.50\,mi)\cdot \left(5280\,\frac{ft}{mi} \right)\cdot \left(12\,\frac{in}{ft} \right)[/tex]

[tex]x = 158400\,in[/tex]

[tex]x = 1.584\times 10^{5}[/tex] (Choice B)

mi - km

[tex]x = (2.50\,mi)\cdot \left(1.61\,\frac{km}{mi} \right)[/tex]

[tex]x = 4.025\,km[/tex] (Different from Choice C)

mi - yd

[tex]x = (2.50\,mi)\cdot \left(5280\,\frac{ft}{mi}\right) \cdot \left(\frac{1}{3}\,\frac{yd}{ft} \right)[/tex]

[tex]x = 4400\,yd[/tex]

[tex]x = 4.40\times 10^{3}\,yd[/tex] (Choice D)

mi - cm

[tex]x = (2.50\,mi)\cdot \left(1.61\,\frac{km}{mi} \right)\cdot \left(100000\,\frac{cm}{km}\right)[/tex]

[tex]x = 402500\,cm[/tex]

[tex]x = 4.025\times 10^{5}\,cm[/tex] (Choice E)

Choice C is not equivalent to 2.50 miles.

Answer:

1.) Time t = 3.1 seconds

2.) Height h = 46 metres

Explanation:

given that the initial velocity U = 30 m/s

At the top of the trajectory, the final velocity V = 0

Using first equation of motion

V = U - gt

g is negative 9.81m/^2 as the object is going against the gravity.

Substitute all the parameters into the formula

0 = 30 - 9.81t

9.81t = 30

Make t the subject of formula

t = 30/9.81

t = 3.058 seconds

t = 3.1 seconds approximately

Therefore, it will take 3.1 seconds to reach to reach the top of its trajectory.

2.) The height it will go can be calculated by using second equation of motion

h = ut - 1/2gt^2

Substitutes U, g and t into the formula

h = 30(3.1) - 1/2 × 9.8 × 3.1^2

h = 93 - 47.089

h = 45.911 m

It will go 46 metres approximately high.

Answer:

19.1°C

Explanation:

If A and B mix to give 16°C, A has risen by 4°C and B has fallen by 3°C;

If B and C mix to give 23°C, B has risen by 3°C and C has fallen by 5°C;

This means the energy transfered to cause a change of 3°C in B causes a change of 4°C in A and 5°C in C;

We can use this as a ratio (4:5);

The temperature difference between A and C is 16°C;

we add the two parts of the ratio (4+5) to get 9 and divide the temperature difference to get 16/9;

Next we multiply this by one of the parts of the ratio, so with 4, you get 64/9;

This number is the proportional temperature change in A upon mixing;

We then add this to the original temperature of A to get the resultant temperature of the mix like so:

64/9 + 12 = 19.1111...

You can do this alternatively using the other part of the ratio;

We would multiply the 16/9 by the 5 instead of the 4 to get 80/9;

This number is the proportional change in temperature in C upon mixing

Then subtract this from this from the original temperature of C and you should get the same answer:

28 - 80/9 = 19.1111...

The second one is best.  Gravity is an attractive force that acts between all objects, whether they're in contact or not.

Gravity is an attractive force that acts between all objects, whether they're in contact or not.

Gravity, also called gravitation, in mechanics, is the universal force of attraction acting between all matter. It is by far the weakest known force in nature and thus plays no role in determining the internal properties of everyday matter.

On the other hand, through its long reach and universal action, it controls the trajectories of bodies in the solar system and elsewhere in the universe and the structures and evolution of stars, galaxies, and the whole cosmos.

On Earth, all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth’s mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects. At Earth’s surface, the acceleration of gravity is about 9.8 metres (32 feet) per second per second.

Thus, for every second an object is in free fall, its speed increases by about 9.8 metres per second. At the surface of the Moon, the acceleration of a freely falling body is about 1.6 metres per second per second.

Hence Gravity is an attractive force that acts between all objects, whether they're in contact or not.

Explanation:

The wave energy is related to its amplitude and frequency.

The wave energy is proportional to the amplitude of the wave. So, wave with the most energy will have high amplitude.

Also, frequency is related to wave energy. The larger the frequency, the more the energy of the wave.

Therefore, The waves with the MOST energy have high amplitudes and large

Answer: M.A = 3

Explanation:

A ramp is an example of an inclined plain. Where the

Height H = 1.5 m

Length L = 4.5 m

Mechanical advantage of a machine is the ratio of the load to effort. While mechanical advantage M.A of an inclined plain is the ratio of the length of the plain to the height of the plain.

M.A = L/H

Substitute the values of L and H into the formula

M.A = 4.5/1.5 = 3

The mechanical advantage of the ramp is 3

Average speed = distance / time

The total distance traveled is 60 km + 84 km + 68 km = 212 km.

The total time is 2 hr + 1 hr + 8.9 hr = 11.9 hr.

The average speed is 212 km / 11.9 hr = 17.8 km/hr

Kinetic energy is greatest at the lowest point of a roller coaster and least at the highest point.

Potential energy will be greatest at the points A and G, and kinetic energy will be greatest at the point D.  

• The energy possessed by an object due to its motion is termed as the kinetic energy. On the other hand, the energy stored within an object because of its position relative to some zero position is known as the potential energy of the object.  

• Kinetic energy is highest when the velocity is the highest, in the case of pendulum, this takes place at the bottom. In the given case, that is, at point D.  

• If kinetic energy is highest at point D, then at the same point potential energy will be the lowest.  

• Therefore, potential energy would be highest at its highest point on each of the side of its motion where it remains stationary for some time, that is, at point G and A.  

Thus, kinetic energy would be highest at point D, and potential energy would be highest at the points A and G.

Explanation:

Answer: 1.81m

Explanation:

Given the following:

Horizontal speed = 4m/s

Height of table = 1m

Taking the vertical component of the motion:

Using:

S = ut + 0.5 at^2

Where, S = height of table, a = acceleration due to gravity (9.8m/s^2), t = time and u = Initial Velocity in vertical direction = 0

1 = 0(t) + 0.5(9.8)t^2

1 = 4.9t^2

t^2 = 1 / 4.9

t^2 = 0.204081

t = sqrt(0.204081)

t = 0.452s

For Horizontal :

Gravitational acceleration is absent, therefore distance can be calculated using:

Distance = Velocity × time

Distance = 4m/s × 0.452s

Distance = 1.808 m

Distance = 1.81m
