Kinetic energy of the horse and rider = 1/2 (mass) (speed)²
At 4.0 m/s : KE = 1/2 (55kg) (4 m/s)² = 440 joules
At 6.0 m/s : KE = 1/2 (55kg) (6 m/s)² = 990 joules
She increased the kinetic energy of herself and her vehicle by 550 joules,
so she must have put at least that much work into it.
Hey, unfortunately it’s impossible for me to draw one for you here, but you should be able to draw it yourself pretty easily!
Answer:
An atom is built with a combination of three distinct particles: electrons, protons, and neutrons. Each atom has a center nucleus, where the protons and neutrons are densely packed together. Surrounding the nucleus are a group of orbiting electrons. And here is a picture that may assist your further :

Answer:
The difference between the Electrolyte and Non-Electrolyte are given in the explanation part.
Explanation:
- ELECTROLYTES are salts or molecules which ionize in solution fully.
- Electrolyte solutions thus conduct electricity readily.
whereas
- NON ELECTROLYTES in water do not dissociate from ions,
- non-electrolyte solutions do not conduct electricity.
Answer:
The answer is C, a thermometer reads 0.1 degree higher than it should.
1) 487 miles / 65 miles per hour = 7.5h at max speed
2) 9.8h - 7.5h = 2.3h rest time avaliable
