Answer:
L
D
Explanation:
At Y, horizontal force is greater than downward force so E or L. However L seems to be more appropriate since horizontal force in L is less than E
At Z, horizontal force is less than downward force so D
Answer:
s = 27 m
Explanation:
given,
acceleration of the car, a = 6 m/s²
time of the travel, t = 3 s
final speed of the car, v = 0 m/s
using equation of motion
v = u + a t
0 = u - 6 x 3
u = 18 m/s
initial speed of the car = 18 m/s
Again using equation of motion
v² = u² + 2 a s
0 = 18² - 2 x 6 x s
12 s = 324
s = 27 m
Distance travel by the car is equal to 27 m.
Because gravity accelerates all objects the same regardless of their mass
The correct answer is option 2. Systems, by
nature, tend to undergo changes toward higher entropy and lower energy since
this is the state where they are most stable. Entropy is the degree of
disorderliness of a substance. Systems tend to go to higher disorder since
systems always tend to change which can be linked to disorder and is
inevitable.
Answer:
2 meters
Explanation:
time is directly proportional to temperarure where distance is the constant k
therefore
T = t x 2a
28=7 x 2a
28= 14a
a=2m
