What's the answer to this question?​

First find the diameter of each.

Jupiter’s diameter is 86,881 mi.

Earth’s diameter is 7,917.5 mi.

Then divide those two.

Rounded, Jupiter is 11 times larger.

unrounded: 10.9732870224186927691821913482791285127

Finding out how large something is compared to something can be done by dividing.

For example I have two dogs. One dog is 3 feet tall. The other is 2 feet tall. How much taller is dog one? Dog one is 1.5 times larger because 3/2 = 1.5 AND 2 x 1.5 = 3.

So for this case multiplying Earth’s diameter by 10.9732870224186927691821913482791285127 will give you Jupiter’s diameter.

Answer:

the ant

Explanation:

because work is done when there will be involvement of displacement in the direction of the force.

Answer:

The ant is doing work but the elephant is not

Explanation:

Work done = Force × Displacement

In case of ant and housefly,

Ants are dragging the housefly , so they are displacing the housefly from one point to the other by applying certain force , so we can say that they are doing work

In case of elephant and tree,

When the elephant is pushing the tree( applying force) , the tree is not moving which means that there is no Displacement, so work done will be

Work done = Force × Displacement

= Force × 0

= 0

Core samples are small portions of a formation taken from an existing well and used for geologic analysis. The sample is analyzed to determine porosity, permeability, fluid content, geologic age, and probable productivity of oil from the site. ... Core samples reveal the physical and chemical nature of the rock.

Explanation:

If transformations from stabilization are minimal, a double pendulum performs basic geometric motion. The highly nonlinear system, furthermore, becomes radically unstable in its motion as significant displacements are introduced, showing that deterministic processes are not inherently predictable

True I guess

because if the force is balanced and there is no net force, the object will not accelerate and the velocity will remain constant...

The value in m/s [tex]v_{a} = 111 \ m/s [/tex]

The value in km/h [tex]v_{a} = 400\ km/h [/tex]

Explanation:

Generally the average velocity of the helicopter is mathematically represented as

[tex]v_{a} = \frac{\Delta D}{ t}[/tex]

substituting [tex]3.33 km = 33.3*10^3\ for\  \Delta D[/tex] and  30.0 s for  t

We have

         [tex]v_{a} =  \frac{33.3 *10^{3}}{ 30}[/tex]

=>     [tex]v_{a} =  111 \  m/s [/tex]

Now converting to km/h

      [tex]v_{a} =  111  *  \frac{3600  *\frac{s}{h} }{1*10^{-3} *\frac{km}{m}} [/tex]

=>  [tex]v_{a} = 400\  km/h [/tex]

Answer:

Voltage is a measure of how much energy is delivered to charge. At its most basic, an electron (basic charge) is imparted 1.602×10^−19 joules when moved through an electric potential difference of one volt. An electron is then said to have an energy of 1 electronvolt. So, voltage is energy divided by charge.

60 - 45 = A. 15

Explanation:

Subtracted because the plane mirror at an angle is incidence of 60°, so then in order to find the value it would be 60-45 and not adding it or dividing and multiplying to find the value thus the answer is 15.

60 - 45 = A. 15. Subtracted because the plane mirror at an angle is incidence of 60°, so then in order to find the value it would be 60-45 and not adding it or dividing and multiplying to find the value thus the answer is 15.

A flat or highly polished surface called a plane mirror reflects light or waves to create an image. It is a polished, smooth surface that creates a virtual representation of the actual object.

A plane mirror is a surface on which an image can only be produced by at least two light beams. The intersection of these two beams can occur inside the mirror or appear to occur somewhere behind the mirror.

The image that follows illustrates how an object appears when viewed via a plane mirror.

Therefore, 60 - 45 = A. 15. Subtracted because the plane mirror at an angle is incidence of 60°, so then in order to find the value it would be 60-45 and not adding it or dividing and multiplying to find the value thus the answer is 15.

Answer:

controlled variable

Explanation:

here you go

A control variable refers to a variable that is not allowed to change during an experiment​.

A control variable or scientific constant can be described as an experimental element that is constant and unchanged throughout the course of the investigation in scientific experimentation.

Control variables can strongly affect experimental results where they are not held constant during the experiment in order to test the relative relationship between the dependent and independent variables.

A variable is held constant in order to assess the relationship between multiple variables in an experiment and is a control variable. A control variable is not changed throughout an experiment because its constant state allows the relationship between the other variables. A control variable is what is kept constant throughout the entire experiment.

Therefore,  a variable that is not allowed to change during an experiment​ is a controlled variable or scientific constant.

Answer:

Compasses are mainly used in navigation to find direction on the earth. This works because the Earth itself has a magnetic field which is similar to that of a bar magnet. The compass needle aligns with the Earth's magnetic field direction and points north-south. Also, In a magnet all the domains are oriented in the same direction. In the case of a nail, the domains can be aligned in the same direction causing the nail to become magnetic. That is because if you hang a bar magnet from a thread, the north pole will point to magnetic north. When you bring one north pole close to another north pole they repel each other. You can feel the two magnets pushing each other apart.

Answer: Answer is D

Answer:

(A) Original speed= 9.22 m/s

(B) Acceleration= -1.0099 m\s^2

Explanation:

A truck covers 40m in 7.10 secs

The truck slows down at a uniform velocity of 2.05 m/s

(A) The original speed can be calculated as follows

Vo= 2(40)/7.10 - 2.05

= 80/7.10 - 2.05

= 11.2676 - 2.05

= 9.22m/s

(B) The acceleration can be calculated as follows

a= Vf-Vo/t

= 2.05-9.22/7.10

= -7.17/7.10

= -1.0099m/s^2

Explanation:

Given that,

A student covered a distance of 210 meters in 35 seconds.

We need to find the student's speed in meters/second and also in meters/minute.

Speed, v = distance (d)/time (t)

So,

[tex]v=\dfrac{210\ m}{35\ s}\\\\=6\ m/s[/tex]

We know that, 1 minute = 60 seconds

[tex]6\dfrac{m}{s}=6\times \dfrac{m}{(\dfrac{1}{60})\ \text{minutes}}\\\\=360\ \text{meters/minutes}[/tex]

Hence, the student's speed is 6 m/s or 360 meters/minute.
