U dont have full and complete questions so i cant answer im sry, if u can give more details i can help u.
C) An unbalanced force is acting on the car in the direction east
Explanation:
The new volume of water = 25 ml
The old volume of water = 15 ml
The difference = 25 - 15 but what are the units?
Since the question asks for force, the units must start out as 10 mL
In water 1 mL has a mass of 1 gram, so the answer is 10 grams.
Grams are units of mass, not weight. You should convert this into newtons.
10 grams = 1/1000 = 0.01 kg
1 kg has a weight of 9.81 Newtons
0.01 kg has a weight 0.081 Newtons
If you have never seen a Newton before, then the answer is 10 grams
Answer:
(A)
(B) s = 146.664 m
Explanation:
We have given car starts from the rest so initial velocity u = 0 m /sec
Final velocity v = 88 km/hr
We know that 1 km = 1000 m
And 1 hour = 3600 sec
So
Time is given t = 12 sec
(A) From first equation of motion v = u+at
So
So acceleration of the car will be
(b) From third equation of motion
So
s = 146.664 m
Distance traveled by the car in this interval will be 146.664 m
