Answer:
5123.79 kg
Explaination:
I did 5,123,788 divided by 1000 and got 5123.788
Then I rounded to the nearest 10th place.
Hope this helps, have a great day!
Answer:
1. D
2. D
3. A
The reason why your body goes right and the car car goes left is because your body tries to stay where it was, which is on the right. Your upper body doesn't feel a force and because of that continues in the same direction. Your lower half is pulled out from under you by seat friction to the left, leaving you leaning to the right.
a. chlorofluorocarbons
Explanation:
The chemical reaction describes the combination of chlorofluorocarbons with ozone.
Reaction 1: ClO + BrO ⇒ Cl + Br + O₂
Reaction 2: Cl + O₃ ⇒ ClO + O₂
Reaction 3: Br + O₃ ⇒ BrO + O₂
O₃ is the ozone molecule, the Cl, and Br are the chlorofluorocarbons.
- In this reaction, ozone is converted into oxygen gas. This reaction takes place in the stratosphere.
- This leads to the penetration and creation of a hole in the atmosphere which allows for ultraviolet rays to reach the earth surface.
- The chlorofluorocarbons are produced on the earth surface in component gases used for making refrigerants, car sprays, air conditioners etc.
- When the reach the ozone layer, they react with it and produce oxygen gas.

Explanation:
Given mass of the object is 1200kg and it's placed at a height of 45m above the ground. As we know that potential energy is ,
where,
- m is the mass of the body .
- g is acceleration due to gravity.
- h is the height above the ground .
Substituting the respective values ,
Multiply ,
<u>Hence</u><u> the</u><u> </u><u>potential</u><u> energy</u><u> is</u><u> </u><u>5</u><u>4</u><u>0</u><u>0</u><u>0</u><u>0</u><u>J</u><u> </u><u>.</u>

Answer:
POSITIVE
Explanation:
The acceleration of an object is given by the rate of change of velocity.
u and v are initial and final velocities
If the final velocity is more than that of the initial velocity, the acceleration of the object is positive. It means positive acceleration occurs when an object speeds up. Hence, the correct option is (a) "positive".
