Answer:
28852 J
Explanation:
When a force applied in a body produces a displacement in it, the force realized a work. The force that moves Karen is contrary to her weight and must be equal to it.
The work (W) is:
W = F.d.cos(θ), where F is the force, d is the displacement, and θ is the angle.
Knowing that cos(26°) = 0.899, and F = m*g
W = 51.9*9.8*63.1*0.899
W = 28852 J
Work is the ability to cause life change??
All the inhabitants of a particular place or town, area or country
Answer:
Measuring cup and graduated cylinder
Explanation:
These tools measure the volume of liquid matter. Measuring cups are used frequently in cooking and provide measurements generally in ounces and grams. A graduated cylinder is used in laboratories and in research and allows for a greater degree of precision in measuring the volume.
energetic electrically charged particles (mostly electrons) accelerate along the magnetic field lines into the upper atmosphere, where they collide with gas atoms, causing the atoms to give off light.
