5) Match the following.

The wavelength and the frequency of the light are inversely proportional to each other, the multiplication of the wavelength and the frequency of the light is equal to the speed of the light.

It can be understood in terms of the distance between any two similar successive points across any wave for example wavelength can be calculated by measuring the distance between any two successive crests.

C = λν

As given in the problem we have to find out how are wavelength, frequency, and energy-related to photons of light,

The relationship between the wavelength and the frequency of light is inverse, and the product of the wavelength and the frequency equals the speed of light.

Answer:

A. It moved from 3 cm to 10 cm at a constant speed of 2 cm/s.

Explanation:

Just took the quiz.

It moved from 3 cm to 6 cm at a constant speed of 3 cm/s.​ This  statement accurately describes the motion of the object in the graph above

An object is said to be in motion , if its position changes with respect to its surroundings and time.

A. Object's motion is from 3 cm to 10 cm at a constant speed of 2 cm/s

let us check

time = 7 sec

distance = 10 - 3 = 7 sec

speed = distance / time = 7/7 = 1 m/s

wrong option

B. Object's motion is from 0 cm to 6 cm at an average speed of 1 cm/s.

distance = 6 cm

time = 7.5 sec

speed = 6/7.5 = 0.8 m/s

wrong option

C. Object's motion is from 0 cm to 10 cm at an average speed of 2 cm/s.

distance = 10 cm

time = 9 sec

speed = 10 / 9 = 1.11 m/s

wrong option

D.  Object's motion  is from 3 cm to 6 cm at a constant speed of 3 cm/s.​

distance = 6-3 = 3 cm

time = 7.5 - 6.5 = 1 sec

speed = 3 /1 = 3 m/s

correct option  D. It moved from 3 cm to 6 cm at a constant speed of 3 cm/s.​

Answer:

There is absolutely No relationship between the weight of an object (which is constant) and the frictional force. If a block is sliding on a surface, that surface will be exerting a force on the block. That force can be resolved into a component parallel to the surface (which we call the frictional component), and a component perpendicular to the surface (called the normal component). For many situations, we find experimentally that the frictional component is approximately proportional to the normal component. The frictional component divided by the normal component is defined to be a quantity called the coefficient of kinetic or sliding friction. The coefficient of kinetic friction obviously depends on the nature of the surfaces involved. The normal component on an object can be decreased if you pull in the direction of the normal component (the weight does not change). However pulling this way on the object not only decreases the normal component, but it also decreases the frictional component since they are proportional. This is why it is easier to slide something if you pull up on it while you push it. If you push down, the normal and frictional components increase so it is harder to slide the object. The weight of an object is the downward force exerted by Earth’s gravity on that object, and it does not change no matter how you push or pull on the object.

Mass of football = 20 grams

Volume of football = 100[tex]cm^{3}[/tex]

To find the density of the football;

Density is simply mass per unit volume of an object such as a football.

Mathematically, the density of an object is given by the formula;

Density=[tex]\frac{Mass}{Volume}[/tex]

Substituting the assumed values into the above formula;

Density=[tex]\frac{20}{100}[/tex]

Density= 0.2g/[tex]cm^{3}[/tex]

Therefore, the density of the football is     0.2g/[tex]cm^{3}[/tex] .

For you: You can substitute the appropriate parameters into the formula to get the exact density of the ball.

The motorized toy boat experiences a net force of 0 N between 4 s and 8 s.

The motorized toy boat moves at 8 m/s (u) at 4 s and at 8 m/s (v) at 8 s. We can calculate the acceleration (a) in that period using the following kinematic expression.

[tex]a = \frac{v-u}{\Delta t} = \frac{8m/s-8m/s}{8s-4s} = 0 m/s^{2}[/tex]

The object with a mass (m) of 2.0 kg experiences an acceleration of 0 m/s². We can calculate the net force (F) in that period using Newton's second law of motion.

[tex]F = m \times a = 2.0 kg \times 0 m/s^{2} = 0 N[/tex]

Answer:

1 / 3 or 0.33

that is if you meant that the object accelerates at 3 m / s² not 3 m / s

for the unit of acceleration is m / s²

Explanation:

m = ?

a = 3

f = 1N

where;

m = mass ( kg )

a = acceleration ( m / s² )

f = force ( N )

from all the parameters we are given, we can use Newton's second law of motion to solve it

that is;

a = f / m

to make m the subject of the formula, we have to cross multiply to give us;

m( a ) = f

divide through by a to give us;

m ( a ) / a = f / a

therefore,

m = f / a

so, we substitute our values to give us;

m = 1 / 3

therefore. m = 1 / 3 or 0. 33

hope this helps
