Answer:
4000J
Explanation:
Given parameters:
Weight of the man = 800N
Height of ladder = 5m
Unknown:
Gravitational potential energy gained = ?
Solution:
The gravitational potential energy is due to the position of a body.
Gravitational potential energy = weight x height
Now insert the parameters;
Gravitational potential energy = 800 x 5 = 4000J
Answer:
you should divide 1700 by the gravity on the space staion
Explanation:
This molecule is formed between a not very electronegative metal and a very electronegative nonmetal which means it should be an ionic compound which would mean that it would have the name of potassium oxide.
look up the naming rules for ionic compounds. I would explain it here but I don't know how to explain naming the anion part of the molecule other than it ends in ide since it is a monoatomic anion which is why oxide is in the name instead of oxygen.
I hope this helps. Let me know if anything is unclear or needs more explanation.
The kinetic energy of the car is
Explanation:
The kinetic energy of an object is the energy possessed by the object due to its motion.
Mathematically, the kinetic energy is
where
m is the mass of the object
v is its speed
For the car in this problem,
m = 740 kg
v = 33.5 m/s
Therefore, the kinetic energy of the car is
