Explanation:
V=u+at
where,
v=final speed
u=initial speed,(starting speed)
a=acceleration
t=time
- v=u+at = 6=2+a*2
6=2+2a
2a=6-2
2a=4
a=4/2 = 2
a =2
2. to find time taken
v=u+at
25=5*2t
2t=25-5
2t=20
t=20/2
t=10sec
3. finding final speed
v=u+at
v=4+10*2
=4+20
v=24m/sec
5.v=u+at
=5+8*10
=5+80
V=85m/sev
6. v=u+at
8=u+4*2
8=u+8
U=8/8
u=1
these are your missing values
Answer:
Independent variable: amount of sugar
Dependent variable: size of the loaf of bread
Explanation:
The amount of sugar the mother adds is completely up to her, and the size of the loaf changes according to that, which is why the loaf size is the dependent variable
Answer:
<h3>0.42s</h3>
Explanation:
Velocity = Displacement/time
Displacement of the horse is the distance covered in a specified direction
Total distance of the horse towards the right = 15m + 20m = 35m
Total distance of the horse towards the left = 4m
Displacement = Distance towards the right - Distance towards the left
Displacement = 35m-4m
Displacement = 31m
Time taken = 74seconds
substitute the values gotten into the velocity formula
average velocity = 31m/74s
average velocity = 0.42m/s
Hence the magnitude of its average velocity is 0.42s
-- On Earth, 1 kg of anything weighs 9.81 Newtons (2.205 pounds). It doesn't matter what substance comprises the kilogram.
-- Although their weights are identical, any mass of feathers occupies more volume than the same mass of iron, no matter where they happen to be located.
-- Iron is more dense than feathers, and more dense than a lot of other substances as well, too.
I believe the answer is valcanos because they release sulfur in to the air and other chemicals so it willl affect the anispher
