How can we transfer a table of motion data into a line graph?

Answer:

The age trend of the volcanoes is thought to be due to the way in which the islands are built on the moving sea floor of the North Pacific Ocean: the Pacific Ocean is mostly floored by a single tectonic plate (known as the "Pacific Plate") that is moving over the layer in the Earth known as the Asthenosphere

Answer:

D. Newton's second law

Explanation:

Newton's second law of motion states that force of an object is a product of its mass and its acceleration.

Mathematically, F= ma where  m is mass and a is acceleration

So from the statement above : The acceleration of an object is proportional to the force applied to it and  inversely proportional to its mass , it can be seen from the formula variation as;

F= ma -----making a the subject of the formula

a= F/ m

a= 1/m * F --------- a  is inversely related to m  as you can see from 1/m but directly related to F  hence;

Increase in mass with the same force applied causes the body to accelerate slower where as when force increases, the body accelerates faster.

Answer:

b

Explanation:

The amount of work done to move an electron from the positive plate to the negative plate is :  7.2 * [tex]10^{-19}[/tex] J

Step 1: Given data

magnitude of two parallel plate ( E ) = 180 N/C

Distance between plates ( d ) = 2.5 cm

magnitude of charge on electron  ( e ) = [tex]1.602 * 10^{-19}[/tex]  C

Step 2 :  determine the work done

Work done = qV = еEd

                           = [tex]1.602 * 10^{-19}[/tex]  *  180 * 2.5

                           = 720 * [tex]10^{-22}[/tex] J  ≈   7.2 * [tex]10^{-19}[/tex] J

Hence the amount of work done to move an electron from the positive plate to the negative plate  =  7.2 * [tex]10^{-19}[/tex] J

Friction of the road on the motorcycle in the opposite direction

Explanation:

khan academy

Answer:

The relative velocity of the motorcycle to a passenger in the car is 30 km/h

Explanation:

The question relates to the principle of relative velocity and reference frames

The given parameters are;

The velocity of the motorcycle, v₁ = 120 km/h

The velocity of the car, v₂ = 90 km/h

The relative velocity of an object X with regards to another object Y is the velocity the object X will seem to be moving with to an observer in the rest frame of object Y written as [tex]\underset{v}{\rightarrow}_{X|Y}[/tex] = [tex]\underset{v}{\rightarrow}_{X}[/tex] - [tex]\underset{v}{\rightarrow}_{Y}[/tex]

Therefore, the relative velocity of the motorcycle to the car is [tex]v_{1|2}[/tex] = v₁ -  v₂, which give;

[tex]v_{1|2}[/tex]  = 120 km/h - 90 km/h = 30 km/h

The relative velocity of the motorcycle to a passenger in the car = 30 km/h.

Its b increased risk of disease

Answer: 2490 J

Explanation:

The formula to calculate kinetic energy is 1/2mv² where,

m = mass = 62.4

v = velocity = 8.94

Kinetic energy = 1/2mv²

= 1/2 × 62.4 × 8.94²

= 1/2 × 62.4 × 79.9236

= 2493.6J

Answer:

105 g.m/s

Explanation:

The law of conservation of momemtum states that initial momemtum is equal to final momentum.

initial momentum of orange ball = 165 g.m/s

initial momentum of green ball = 0 g.m/s

final momentum of orange ball = 60 g.m/s

final momentum of green ball = x

165+0=60+x

⇒x = 165-60= 105 g.m/s

the momentum of the green ball right after the collision =105 g.m/s

d: gas

e: gas

f:  liquid

Explanation:

According to the forces of attraction, the states of matter in each case serially are as follows: solid, liquid,liquid,gas,gas and liquid respectively.

Matter in chemistry, is defined as any kind of substance that has mass and occupies space that means it has volume .Matter is composed up of atoms which may or not be of same type.

Atoms are further made up of sub atomic particles which are the protons ,neutrons and the electrons .The matter can exist in various states such as solids, liquids and gases depending on the conditions of temperature and pressure.

The states of matter are inter convertible into each other by changing the parameters of temperature and pressure.Matter can neither be created nor destroyed rather is conserved at end of chemical change.

When a wire with a current is placed in a magnetic field, electrical energy is transformed into mechanical energy. The transformation happens when the magnetic field produced by the current causes the wire to move.

Answer: Wind follows a pattern because the Earth is spinning in one motion. If we were spinning in one way then another we would have one day go by then the spinning cycle would change and we would have to go through that day all over again, it would not be logical because then we would be in the same season as well, we would be in one season for the rest of our lives until we died.

The kinetic energy is expressed as

KE= 1/2m(v)²

Given data

Mass of cell phone m= 80g--to kg=80/1000= 0.08kg

Velocity of cell phone v= 15m/s

Substituting our given data we have

KE= 1/2*0.08(15)²

KE= (0.08*225)/2

KE=18/2

KE= 9J

Explanation:

because its cold

soup is hot

Answer:

(a) (i) 1) The mass of the water is 1.8 × 10⁹ kg

2) The gravitational potential energy is 6.174 × 10¹² J

4) The energy given to the turbine by the falling water is 6.174 × 10¹² J

5) The maximum possible average output power is 245 MW

Explanation:

In the question we are required to convert the total initial potential energy, P.E., of the water to power

The given parameters are;

The height of the reservoir above the turbine, h = 350 m

The time duration the volume of water takes to flow, t= 7.0 hours

The volume of water that flows down from the reservoir, V = 1.8 × 10⁶ m³

The density of the water, ρ = 1000 kg/m³

(a) (i) Density = Mass/Volume

∴ Mass = Density × Volume

The mass of the water that flows down from the reservoir = m = V × ρ

By substituting the known values, we have

The mass of the water, m = 1.8 × 10⁶ m³ × 1000 kg/m³ = 1.8 × 10⁹ kg

2) The gravitational potential energy, P.E. = m × g × h

where;

m = The mass of the water = 1.8 × 10⁹ kg

g = The acceleration due to gravity = 9.8 m/s²

h = The height from which the water falls = 350 m

Which gives;

The gravitational potential energy,

P.E. = 1.8 × 10⁹ kg × 9.8 m/s² × 350 m = 6.174 × 10¹² J

The gravitational potential energy = 6.174 × 10¹² J

4) The energy given to the turbine by the falling water, E = The gravitational potential energy = 6.174 × 10¹² J

5) The maximum possible average output power, P = (Energy given to the turbine, E)/(Time taken to produce the energy = The time duration the water takes to flow, t)

The time duration the water takes to flow, t = 7.0 hours = 7 × 60 × 60 seconds =  25,200 seconds

∴ P = 6.174 × 10¹² J/(25,200 s) = 245,000,000 watts = 245 MW

Answer:

1626.4 N

Explanation:

Given that a 82 kg man, at rest, drops from a diving board 3.0 m above the surface of the water and comes to rest 0.55 s after reaching the water. What force does the water exert on him?

The parameters to be considered are:

Distance S = 3m

Time t = 0.55s

Since the man started from rest, initial velocity u = 0

Using second equation of motion

S = Ut + 1/2at^2

3 = 1/2 × a × 0.55^2

3 = 1/2 × a × 0.3025

a = 3/ 0.15125

a = 19.83 m/s^2

Force = mass × acceleration

Force = 82 × 19.83

Force = 1626.4 N

Therefore, the force that water exerted on him is 1626.4 N

Explanation:

Hooke's Law: Fe = kx

x = Fe / k = (22.0N) / (4.00N/cm) = 5.50cm.

10.00cm + 5.50cm = 15.50cm

The new length of the spring is 15.50cm.
