Answer:
366 m
Explanation:
u = 90 km/h = 25 m/s,
theta = 5 degree
acceleration, a = g Sin theta = 9.8 x Sin 5 = 0.854 m/s^2
The final velocity os zero and let the braking distance be s.
Use third equation of motion
v^2 = u^2 - 2 a s
0 = 25 x 25 - 2 x 0.854 x s
s = 366 m
Answer:
Amorphous solids are composed of atoms or molecules that are in no particular order. Each particle is in a particular spot, but the particles are in no organized pattern. Examples include rubber and wax. Crystalline solids have a very orderly, three-dimensional arrangement of atoms or molecules
Explanation:
Answer:
60 m
Explanation:
The boat has two separate motions:
1- A motion due north, with constant speed of 10 m/s
1- A motion due east, due to the current, at speed of 2 m/s
We know that the river is 300 m wide, so we can consider first motion 1) to find how much does it take for the boat to cross the river:
Now we can find how far downstream the boat moved by calculating the distance that the boat covered moving east during this time interval:
Answer:
or the other answer is venn diagram if your on another question
Explanation:
I can't give you the actual number of turns, because it's the RATIO
that counts.
However many turns the primary has, the secondary should have
about TEN TIMES that number. Then the transformer will multiply
the primary voltage by 10 ... 120 volts of AC at the primary will
become 1,200 volts of AC at the secondary.
Note that it HAS TO be AC. If the transformer is supplied with DC,
then 120 volts at the primary becomes zero volts at the secondary
and a big cloud of stinky smoke in the room.
