Which statement best defines the relationship between work and energy?
alexdok [17]

The relationship between work and energy is that work can transfer energy between objects and cause a change in the form of energy.

<h3>What is energy?</h3>

Energy is simply defined as the ability to do work.

Energy possessed by any object or matter enables it to do work of various forms.

Energy can be transferred from one object to another. Also, energy can be transformed into various forms.

Therefore, the relationship between work and energy is that work can transfer energy between objects and cause a change in the form of energy.

centimeter or millimeter.

Explanation:

The unit of length most suitable for measuring the thickness of a cell phone is centimeter or millimeter.

Length refers to how long a material is.

  • There are different units of length.
  • Smaller units that are microscopic are used to measure length dimensions that are very small
  • For example, nanometre is used to express microscopic length values.
  • Centimeters and millimeters are used for small dimensions that we can easily see.
  • Longer lengths can take the order of a yard, kilometer, miles e.t.c

Darya [45]

Given that,

Mass of object, m = 55 kg

Mechanical energy of the object, M = 4306 J    

Potential energy, P = 2940 J

We know that the mechanical energy is the sum of kinetic and potential energy such that,

Mechanical energy = kinetic energy + potential energy

K=M-P\\\\K=4306-2940\\\\K=1366\ J

Kinetic energy is given by :

K=\dfrac{1}{2}mv^2v is velocity of object

v=\sqrt{\dfrac{2K}{m}} \\\\v=\sqrt{\dfrac{2\times 1366}{55}} \\\\v=7.04\ m/s

So, the velocity of object is 7.04 m/s.

ivanzaharov [21]

Solution: C. Pangea

The hypothesis of Continental drift suggests that in past, there was only one landmass on the Earth -Pangaea which drifted apart due to movement of plate tectonics causing earthquake. This hypothesis is supported by many evidences which includes presence of similar fossils on different landmasses, common land features such as widespread presence of glacial sediments etc.
