Use F=ma to solve for a=0.25m/s^2. Now to get distance you need to integrate this twice to get
x=(1/2)at^2. Plug in a and t to get
x=2m
I believe the correct answer from the choices listed above is the last option. The advances in food production that were attributed to the Green Revolution of the 1960s and 1970s are drought-resistant varieties of crop plants.
Hope this answers the question. Have a nice day.
The answer to 9-(-9) is 18.
Answer:
0.4752 oz.
Explanation:
Length = 1000 ft
Converting ft to inches,
12 in = 1 ft
1000 ft = 1000 * 12
= 12000 in
0.05082 in = 0.12908 cm
Mass = 19.8 lb
Converting lb to oz,
1 ounce = 0.0625 lb
1 lb = 1/0.0625 oz
19.8 lb = 1/0.0625 * 19.8
= 316.8 ounce
Since, 12000 in of copper wire weighs 316.8 ounces.
Therefore, 1 in will weigh = 316.8/12000
= 0.0264 oz
18 in = 0.0264 * 18
= 0.4752 oz.
Answer:
Explanation:
<u>The total momentum of a system is defined by:</u>
Where,
is the total momentum or it could be expressed also as 
.
and 
represents the masses of the objects interacting in the system.
and 
are the velocities of the objects of the system.
<em>Remember: </em><em>The momentum is a fundamental physical magnitude of vector type.</em>
We have:
We are going to take the east side as positive, and the west side as negative. Then the velocity of the car B, has to be <u>negative</u>. It goes in a different direction from car A.
Then the total momentum of the system is:
