Answer:
The force is -1620.73 N.
Explanation:
Given that,
Mass of car = 1000 kg
Velocity = 1 m/s
Distance = 2 m
Angle = 30°
We need to calculate the force
Using formula of work done





Put the value into the formula


Hence, The force is -1620.73 N.
You need to move the decimal point between the six and nine. 6.9 X 10^-4
If the same atoms appear on both sides, then it's balanced.
In this reaction, there are 4 Oxygens, 2 Carbons, and 2 Nitrogens on each side. So numerically, <em>it's balanced</em>. But I don't know enough chemistry to say whether the reaction is possible.
Answer: 83.3 W
Explanation: I think, I’m not sure. If I’m wrong correct me ;)
