A object has a mass of 13 Kg . - 17 Calculate the mass of this object on the surface of Jupiter . ( The gravity of Jupiter is 26

N / kg ) ​
Physics
1 answer:
Nonamiya [84]3 years ago
7 0

Explanation:

It is given that,

Mass of an object is 13 kg

We need to find the mass of this object on the surface of Jupiter.

The mass of an object is the amount present in it. It it independent of location. It mass remains the same at Jupiter as well. Its does not depend on the gravity on that surface.

Hence, its mass will remain 13 kg on the surface of Jupiter.

A strong magnetic field surrounds Earth. How does Earth’s magnetic field help humans?
elena-14-01-66 [18.8K]

A strong magnetic field surrounds Earth and (C) It keeps the solar wind from reaching Earth. If all the particles of the solar wind contact the earth, they would make the ozone layer disappear. The ozone layer is the one in charge of protecting the earth from the ultraviolet radiation.

An Airbus A320 jetliner has a takeoff mass of 75,000 kg. It reaches its takeoff speed of 82 m/s (180 mph) in 35 s. What is the t
timofeeve [1]

Answer:

175.5 kN

Explanation:

We find the acceleration of the Airbus A320 jetliner from,

a = (v - u)/t where u = initial velocity of jetliner = 0 m/s (since it starts from rest), v = final velocity of jetliner = 82 m/s and t = time for velocity change = 35 s

So a = (v - u)/t = (82 m/s - 0 m/s)/35 s = 82 m/s ÷ 35 s = 2.34 m/s²

Now, the thrust of the engines on the jetliner T = ma where m = mass of jetliner = 75,000 kg and a = acceleration of jetliner = 2.34 m/s²

T = ma

= 75,000 kg × 2.34 m/s²

= 175500 N

= 175.5 kN

Weber theorized that we would eventually get stuck in ______, where we move from one formalized structure to the next, unable to
dsp73

Answer:

The correct answer is

d. An iron cage

Max Weber is well known for developing the theoretical concept of the iron cage

Explanation:

The theory of the iron was first presented by the sociologist Max Weber in the work  The Protestant Ethic and the Spirit of Capitalism.

Here Weber clarified that with the diminishing effect of Protestantism within our social life the capitalist system remained as well as the bureaucratic principles and social structures that came about along with came along with it, such the worldviews and values becomes major controlling factors in socil life which is tantamount to living in a strong house maade of steel

How is wave movement affected by the various mediums it may travel through?
Juliette [100K]

Answer:

speed is affected by the medium in wich the wave travels.

Explanation:

The speed of a wave is affected when traveling in different medium, depending on the medium in which the wave travels it can go faster or slower, or not even be able to travel in that medium.

For light waves, the denser the medium through which the wave travels, the slower it will go through it, as there is more resistance to the light particles.

And in waves like sound, which instead of particles is a vibration or disturbance in the medium, they travel faster in denser mediums such as metal, because the disturbance is transmitted more efficiently thanks to how close together that the particles are in the metal, This is why sound does not travel in a vacuum; there are not even particles to transmit the vibration.

A 62.6-kg skateboarder starts out with a speed of 2.18 m/s. He does 113 J of work on himself by pushing with his feet against th
n200080 [17]

Answer:

a. Wgra=786.09J

b. 1.28m

Explanation:

The change in the potential energy is the work done by the gravitational force.

For this problem you have to take into account that the total work done is given by the change in the kinetic energy

W_{tot}=\Delta E_k=\frac{m}{2}(v_f^2-v_0^2)\\W_{tot}=\frac{62.6kg}{2}((6.55\frac{m}{s})^2-(2.18\frac{m}{s})^2)=1194.09J

Furthermore the total work is the contribution of the work done by the skater, the gravitational force and the friction

W_{tot}=W_{ska}+W_{fric}+W_{gra}

(a) by separating Wfric you have

W_{gra}=W_{tot}-W_{fric}-W_{ska}=1194.09J-295J-113J=786.09J

(b) It is only necessary to use the expression for the work done by gravitational force

W_{grav}=mgh\\h=\frac{W_{grav}}{mg}=\frac{786.09J}{(62.6kg)(9.8\frac{m}{s^2})}=1.28m

HOPE THIS HELPS!!
