A man pulls on his dog's leash to keep him from running after a bicycle. Which term best describes this example?

We know the answer doesn't have to do with force because we have not identified a positive or negative axis.

Depending on what the system we are evaluating is, the sign of the work can change.

If work is done on the system, it is negative, but if work is done by the system, it is positive.

If the system we are evaluating is the leash, the work is being done by the leash, and therefore, the work is positive.

If the system we are evaluating is the dog, the work is being done on the dog, and therefore, the work is negative.

In a light wave, which properties tell you the color of light?

Alenkasestr [34]

Answer :-  In a light wave the property of wave which tells about the color of light is it's Wavelength . 

Wavelength is the distance between one crest and one through , also it is the distance after which the wave repeat itself !

It's SI unit is meter !

It is scalar quantity !!

Different Wavelength of light have different color !!

<h2>• VIBGYOR </h2>

i.e, Violent , Indigo , Blue , Green , Yellow Orange, and Red along with their shades are the colors which we can see !!

• They almost range from 400nm to 700nm ( visible range of light )

the deepest point in the sea is 100m below sea level .what arr the water pressure at this depth and the total pressure due to wa

fomenos

The water pressure at this depth and the total pressure due to water and atmosphere are 10.3 x 10⁵ Pa and 11.31× 10⁵ Pa.

<h3>What is pressure?</h3>

The pressure is the amount of force applied per unit area.

Atmospheric pressure, Patm =1.01×10⁵ Pa

Density of water, ρ=1030 kg/m³

Depth, h=100 m

Pressure =ρgh

P = 1030×10×100

P = 10.3 x 10⁵ Pa.

Total pressure, P=Po +ρgh

P=1.01×10⁵ + 1030×10×100

P=11.31× 10⁵ Pa

Hence, total pressure is 11.31× 10⁵ Pa.

In deep space, sphere A of mass MA is located at the origin of an x axis and sphere B of mass MB is located on the axis at a poi

Nookie1986 [14]

Answer:

The gravitational potential energy of the two-sphere system just as B is released is

U = -[(G)(MA)(MB)/x₁]

where G = Gravitational constant

G = (6.7 × 10⁻¹¹) Nm²/kg²

Explanation:

The gravitational potential energy of two masses (m and M), separated by a distance, d, is given as

U = -(GMm/d)

For our question,

Mass of object 1 = MA

Mass of object 2 = MB

Distance between them = x₁

U = -[(G)(MA)(MB)/x₁]

where G = Gravitational constant

G = (6.7 × 10⁻¹¹) Nm²/kg²

Hope this Helps!!!
