Calculate The Mass Marvin The Martian If His Weight On Mars Is 340 N. Acceleration Due To Gravity On (2024)

Newton's third law we find that the correct statement for the forces that push the pencil on the table is:

c) Normal friction

Newton's third law establishes that the force acts in pairs one of them is called action and the other reaction, one on each interacting body, the two are of the same magnitude and of opposite direction.

In the attached diagram we have a free-body diagram of the force on the pencil on the table. Let's analyze the statements to find the force that pushes the pencil up.

a) False. Gravity is directed towards the center of the earth, therefore it acts downwards.

b) False. Friction is the one that opposes the displacement of the pencil tip is horizontally.

c) True. The Normal Force is the reaction of the Earth by the support of the pencil on the surface, acts in a vertical direction upwards.

d) False. The sliding friction in the friction force that is put to the displacement of the entire pencil, is in the horizontal direction.

In conclusion using Newton's third law we find that the correct statement is:

c) Normal friction

Answer:

27.5μC

Explanation:

Given:

m=8.5*10^-3

E=1750N/C

Fg=9.8m/s^2

θ to vertical = 30°

Find:

Q

Fg=mg=8.5*10^-3 * 9.8 = 0.0833N

Tcos(30)=mg -> T=(mg)/cos(30) = 0.096N

Fe(force of electric field on charge) = Tsin(30) = 0.096sin(30) = 0.048N

E=F/Q -> Q=Fe/E = 0.048/1750 = 27.5μC

(see attachment)

We have that the the magnitude of charge Q is mathematically given as

Q=27.5uC

Magnitude of charge

Question Parameters:

a point charge q of mass 8.50 g hangs from the horizontal ceiling by a light 25.0-cm thread.

when a horizontal electric field of magnitude 1750 n/c is turned on

Generally the equation for the Tension is mathematically given as

For Horizontal Direction

[tex]Tsin \tTsin \theta=Q\theta=QE[/tex]

For Vertical Direction

[tex]Tcos\theta=mg[/tex]

[tex]tan\theta=\frac{QE}{mg}[/tex]

Hence

[tex]Sin \theta=\frac{r}{e}\\\\\theta=sin^{-1}(12.5/25)=30\\\\And\\\\tan \theta=\frac{QE}{mg}\\\\[/tex]

[tex]Q=\frac{mg+tan\theta}{E}\\\\Q=\frac{8.5e-3*9.8*tan \theta 30}{1750}[/tex]

Q=27.5uC

Time period=7.1s

[tex]\boxed{\sf Frequency=\dfrac{1}{Time\:Period}}[/tex]

[tex]\\ \tt\longmapsto Frequency=\dfrac{1}{7.1}[/tex]

[tex]\\ \tt\longmapsto Frequency=0.14Hz[/tex]

A lighthouse flashes every 7.1 seconds then the frequency would be 0.1408 hertz.

What is the frequency?

It can be defined as the number of cycles completed per second. It is represented in hertz and inversely proportional to the wavelength.

C=λν

As given in the problem, if a lighthouse flashes every 7.1 seconds we have to find out its frequency,

The time interval between the flashing of the light from the lighthouse = 7.1 seconds

The frequency of the flashing of light from the lighthouse = 1/ 7.1 seconds

=0.14084

Thus, if a lighthouse flashes every 7.1 seconds then the frequency would be 0.1408 hertz.

Answer:

3.65

Explanation:

730/200=3.65

it could also be 200/730=0.273

The time taken will be "3.65 hours".

Given values are:

Speed,

200 km/hr

Distance,

730 km

As we know the formula,

→ [tex]Speed = \frac{Distance}{Time}[/tex]

or,

→ [tex]Time = \frac{Distance}{Speed}[/tex]

By putting the values, we get

[tex]= \frac{730}{200}[/tex]

they both are relative terms

Answer:

100.1 days / (14.3 days/half-life) = 7 half-lives

(1/2)^7 = .00781 amount left after 7 half-lives

1200 kg ^ .00781 = 9.38 kg

At the end of this period, phosphorus-32 remains 9.375 grams.

What is half-life of radio-active material?

A radionuclide's half-life is the amount of time it takes for half of its radioactive atoms to decay. A good rule of thumb is that you will have less radiation than 1% of the original amount after seven half-lives.

Given parameters:

Initial mass of the phosphorus-32 block = 1.200 kg.

Half-life of phosphorus-32 = 14.3 days.

Given time = 100.1 days

100.1 days = (100.1/14.3) half-life of phosphorus-32

= 7 half-life of phosphorus-32.

Hence, at the end of this period, phosphorus-32 remains = initial mass × (1/2)⁷

= 1.20 × (1/2)⁷ kg.

= 0.009375 kg

= 9.375 grams.

Answer:

scalars have a magnitude and a direction, vectors have only magnitude

In the study of physics, scalar quantities are the quantities which can be fully defined by magnitude only whereas vector quantities are the quantities which require both direction and magnitude to define.

What are scalar and vector quantities?

Physical quantities like mass and electric charge are examples of scalar quantities because they only have magnitudes. In contrast, a vector quantity is a physical quantity like force or weight that has both magnitudes and directions.

Physical quantities with merely magnitude and no direction are referred to as scalar quantities. These physical quantities can be explained just by their numerical value without any further guidance. These physical values can be added according to the basic algebraic rules.

A physical quantity that has both directions and magnitude is referred to as a vector quantity. A vector with a magnitude of one is referred to as a unit vector.
