natulia [17]

Answer:

B.The slinky descriptions of motion are switched.

Explanation:

First of all, let's define the two types of wave:

- Transverse wave: in a transverse wave, the oscillation of the wave occurs in a direction perpendicular to the direction of propagation of the wave. An example of transverse wave are electromagnetic waves.

- Longitudinal wave: in a longitudinal wave, the oscillation of the wave occurs in a direction parallel to the direction of propagation of the wave. An example of longitudinal wave are sound waves.

According to these definitions, we notice that the following descriptions of motion must be switched:

- "Like moving a spring up and down" --> this better describes a transverse wave, because the motion up/down is perpendicular to the direction of the spring

- "Like moving a spring back and forth" --> this better describes a longitudinal wave, because the back/forth motion is parallel to the direction of the spring

What will be the weight of a box, mass 10Kg on the surface of a hypothetical planet having mass double of Earth and the radius i
vlada-n [284]

Answer:

           W ’= 21.78 kg

Explanation:

The expression for weight is

          W = m g

let's look for the acceleration of gravity with the universal law of gravitation

          F = G m M / r2

          F = m (G M / r2)

without comparing the two equations

          g’= G M / r2

in that case M = 2 Mo and r = 3 ro

where mo and ro are the mass and radius of the earth

         we substitute

         g ’= G 2Mo / (3r₀) 2

         G ’= 2/9 G Mo / r₀²

         g ’= 2/9 g

the weight of the body on this planet is

         W ’= m g’

          W ’= m 2/9 g

let's calculate

          W ’= 2/9 10 9.8

           W ’= 21.78 kg

Yor older sister drove 500 miles to college one way in ten hours. what is her average velocity?
Lubov Fominskaja [6]
Average velocity is calculated as the division of displacement and change in time so the answer would be 804 km/36000 s=0.02 m/s

When a hot and cold object are placed in contact, the hot one loses energy. Does this violate energy conservation? Why or why no
blsea [12.9K]

Answer:

This does not violate the conservation of energy.

Explanation:

This does not violate the conservation of energy because the hot body gives energy in the form of heat to the colder body, this second absorbs energy. This will be the case until both bodies reach the same temperature, reaching thermal equilibrium and reducing the transfer of thermal energy. In this way the energy was only transferred from one body to another but the total energy of the system (body 1 plus body 2) will be the same as in the beginning, respecting the principle of conservation of energy or also called the first principle of thermodynamics .

The part of physics that studies these processes is in turn called heat transfer or heat transfer or thermal transfer. Heat transfer occurs whenever there is a thermal gradient or when two systems with different temperatures come into contact. The process persists until thermal equilibrium is reached, that is, until temperatures are equalized. When there is a temperature difference between two objects or regions close enough, the heat transfer cannot be stopped, it can only be slowed down.
