Answer:

the branch of science concerned with the nature and properties of matter and energy. The subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms.

physics, science that deals with the structure of matter and the interactions between the fundamental constituents of the observable universe. In the broadest sense, physics (from the Greek physikos) is concerned with all aspects of nature on both the macroscopic and submicroscopic levels.

Answer:

Physics is a natural discipline that examines matter, its mobility and behavior in space and time, as well as energy and force, which are related phenomena. Physics is one of the most basic scientific fields, with the objective of understanding how the universe works.

Many liberal arts fields include physics, which adds to society's understanding of topics such as energy, meteorology, medical science, and space exploration. A challenging major will equip students with the necessary preparation for graduate studies in physics.

3. The largest asteroid in the solar system is 1 Ceres. It has a mass of 9.3835

Ira Lisetskai [31]

Answer:

2.8351×10^7 N/kg

Explanation:

We know that,

W = mg -------(1)

where W = weight, m = mass, g = gravitational acceleration

Also from Newton's law of gravitation we know that,

F = GMm/r²

Where,

F = gravitational force,

G = universal gravitational constant

M,m = masses of object under gravitational influence

r = distance between the two center of masses.

Here we get

F = (Gm/r²)M -------(2)

From 1 and 2

The acceleration due to gravity = gravitational field intensity

So if you consider the gravitational field intensity at the surface of the asteroid,it is equal to the acceleration due to gravity at the same place.

So we get,

g = (6.67×10^-11)×9.3835×10^20/(47²) = 2.8351×10^7 N/kg

I'm a little bit unsure about this question.

slava [35]

Answer:

Option C. 4 Hz

Explanation:

To know the correct answer to the question given above, it is important we know the definition of frequency.

Frequency can simply be defined as the number of complete oscillations or circles made in one second.

Considering the diagram given above, the wave passes through the medium over a period of one second.

Thus, we can obtain the frequency by simply counting the numbers of complete circles made during the period.

From the diagram given above,

The number of circles = 4

Thus,

The frequency is 4 Hz

enyata [817]

Answer:

The maximum frequency of revolution is 3.6 Hz.

Explanation:

Given that,

Mass = 8 kg

Distance = 400 mm

Tension = 800 N

We need to calculate the velocity

Using centripetal force

$F=\dfrac{mv^2}{r}$

Where, F= tension

m = mass

v= velocity

r = radius of circle

Put the value into the formula

$800=\dfrac{8\times v^2}{200\times10^{-3}}$

$v^2=\sqrt{\dfrac{800\times200\times10^{-3}}{8}}$

$v=4.47\ m/s$

We need to calculate the maximum frequency of revolution

Using formula of frequency

$f=\dfrac{v}{2\pi r}$

Put the value into the formula

$f=\dfrac{4.47}{2\pi\times200\times10^{-3}}$

$f=3.6\ Hz$

Hence, The maximum frequency of revolution is 3.6 Hz.

The velocity versus time graph of particle A is tangent to the velocity versus time graph for particle B at point O. What is the

lara [203]

As velocities are tangent, the value of both Particle A and Particle B would be same for that point O (Intersecting point)

a = v / t
Here, v = 7, t = 6
So, a = 7/6
a = 1.17
As the graph is decreasing, value of acceleration would be negative.
So, a = -1.17 m/s²

In short, Your Answer would be Option C

Hope this helps!
