Answer:

5 kilometers

Explanation:

Velocity= 15km/h

Time= 20 minutes = 1/3 hours

Displacement= Velocity x Time

= 15 x 1/3

= 15/3

= 5km

Answer:

Answer:

The bowling ball did not change size or shape- the only thing that changed was the amount of gravity that pulls on it. But the mass of the bowling ball would never change. A bowling ball with a mass of 12 pounds on earth will have the mass of 12 pounds on the moon! Mass is the amount of atoms that a space fills.

Answer:

The answer is SYMBOL B.

Explanation:

The correct schematic is the one that shows three groups of long and short lines. A schematic with one long and one short (one group) would be a one cell; a schematic with a long, a short, a long, a short (two group), would be a two cell; and a schematic with a long, a short, a long, a short, a long and a short (three group), would be a three cell- hence why the answer is symbol B.

Answer:

When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another. This is similar to electric charges. Like charges repel, and unlike charges attract.

Answer:

650 N / 0.10 m2 = 6500 Pa

Explanation:

The pressure that could be exerted on the ground with each top should be 6,500 Pa

Given that,

We need to determine the pressure.

So, the following formula should be used.

[tex]= \frac{Mass}{area}\\\\= \frac{650}{0.10} \\\\[/tex]

= 6,500 Pa

Therefore we can conclude that the pressure that could be exerted on the ground with each top should be 6,500 Pa.

Anxiety disorders are not completely curable.

An anxiety disorder is a disorder in which an individual easily develops feelings of anxiety even in situations which do not warrant such feeling.

The individual feels excessively anxious that it becomes a disability and does not allow the individual to live a  normal life.

There are five main types of anxiety disorders and they are as follows:

Anxiety disorders are not completely curable since they are purely psychological problems.

However, therapy and psychological assistance can lessen symptoms.

Answer:

The correct answer is - Regular soda can would sink and diet soda can will float.

Explanation:

The correct answer is - Regular soda can would sink and diet soda can will float.

Reason - As diet soda cans contains artificial sweetener so, the weight of the diet soda can is less the the eight of the regular soda so. Due to this reason , diet soda can will float and another one sinks in water.

Answer:

By decreasing the resistance

Answer:

0.50 A

Explanation:

According to the formula, V = IR

9 = I×18

I = 9/18

I = 0.50

If the battery is a 9-volt battery and the resistance in the circuit is 18 ohm's then the current is flowing through the circuit would be 0.5 Ampere.

Resistance is the obstruction of electrons in an electrically conducting material.The mathematical relation for resistance can be understood with the help of the empirical relation provided by Ohm's law.

V=IR

Where V is the voltage
Where I is the current
Where R is the resistance used in the circuit

As for the given problem  if the battery is a 9-volt battery and the resistance in the circuit is 18 ohm

By using the ohms

V=IR

By substituting the respective value of voltage and resistance
Voltage is 9 volt in the resistance is 18 ohm

9V = 18*I

I= 0.5 Ampere

Thus, the current flowing through the 9 V battery and a 18 Ohm resistor is 0.5 Ampere.

Explanation:looked it up for ya

Answer:

The correct option is;

The assertion is correct, but reason wrong

Explanation:

The question is with regards to the relationship between work, energy, power, and velocity

The mass of each of the persons running up the staircase = Different

The time it takes each person to run up the stairs = Equal time

Let, 'm₁' and 'm₂' represent the mass of each of the persons that ran up the stairs and m₁ > m₂

Let 't' represent the equal time it takes then to run up the stairs

Let 'h' represent the height of the stairs

The energy, 'E', it takes to run up the stairs is equal to the potential energy, P.E., obtained at the top of the stairs

P.E. = m·g·h

Where;

m = The mass of the person at an elevated height

g = The acceleration due to gravity = Constant

h = The height reached above ground level

Given that the height reached is the same for both of the persons, we have

For m₁, P.E.₁ = m₁·g·h and for m₂, P.E.₂ = m₂·g·h

Therefore, where, m₁ > m₂, we have;

P.E.₁ > P.E.₂

∴ E₁ > E₂

Power, 'P', is the rate at which energy is expended

∴ Power, P = E/t

∴ P₁ = E₁/t  > P₂ = E₂/t

Therefore, the person with the greater mass, 'm₁', uses more power than the person of mass 'm₂', in running up the stairs

Therefore, the assertion is correct

The average velocity, vₐ = (Total distance traveled, d)/(Total time taken, t)

Given that the distance, 'd', covered in running up the stairs by both persons is the same, and the time it takes them to complete the distance, 't', is also the same, we have;

The average velocity of the person with the greater mass m₁ is the same as the average velocity of the person with mass, m₂

Therefore, the reason is wrong

The answer is that the assertion is correct, but reason wrong

Answer:

yes

Explanation:

there are other quantities that are dimensionless, but have a unit.

For example, radian is the unit for an angle. But it is dimensionless because it is defined to be the ratio of two lengths.,

a dimensionless quantity will always be independent of the base units — meter, second, kilograms, kelvin, candela, moles, ampere.

Other examples:

1. Mass fraction

2.Mole fraction

both have unit (kg/kg)

Answer:

A quantity that has dimensions must have units. Yes a quantity have units but still be dimensionless for example,unit of angle is radian ,but it is a dimensionless quantity. A dimensionless quantity may have unit. ... A unitless quantity never has a non-zero dimension.

Answer:

1.4765 Hz

Explanation:

right on acellus

The frequency of an event is the inverse of time period.The frequency of the kid on bouncing the pogo stick is 1.47 Hz.

Frequency of an event is is the number of occurance of that event in unit time. It is the inverse of time period of that event. Hence frequency has the unit of s⁻¹ which is equivalent to Hz.

The frequency of a wave is the number of wave cycles per unit time. Frequency is directly related to the energy of the vibration or wave. Hence, as the frequency increases, energy increases.

Given that, the number of oscillations from the bouncing of the pogo stick is 22 times in 14.9 seconds. Thus , number of oscillations in 1 second is:

22 /14.9 s = 1.47 Hz.

Therefore, the frequency of the event created by the kid is 1.47 Hz.
