Answer:
D.
Explanation:
In nuclear reaction very small amount of matter is converted into significant amount of energy.
Answer:
The maximum height will be 7408.8 meters
Explanation:
final velocity = initial velocity + acceleration × time
final velocity = 0 m/s + 58.8 m/s^2 ×6 s
Final velocity = 352.8 m/s
final velocity ^2 = initial velocity ^2 + 2 × acceleration × displacement
(352.8)^2 = (0)^2 + 2×58.8 ×displacement
Solving for displacement,
height = 1058.4 meters.
After this, the rocket is in free fall, we can use the same equation.
final velocity ^2 = initial velocity ^2 + 2 ×acceleration×displacement
final velocity = 0
0^2 = 352.8^2 + 2×(-9.8)×displacement
displacement = 6350.4 meters
the maximum height will be 7408.8 meters
Answer:
F = M a is a vector equation
F has the same sign as A and is in the same direction as the vector a
If a is positive then F must also be positive
Any change in speed or direction of motion is acceleration.
Constant acceleration can mean ...
-- speeding up at a constant rate . . . gaining the same amount
of speed each second.
-- slowing down at a constant rate . . . losing the same amount
of speed each second.
-- changing direction at a constant rate . . . for example, going
around a circular path at a constant speed.
Answer:
d' = d /2
Explanation:
Given that
Distance = d
Voltage =V
We know that energy in capacitor given as
If energy become double U' = 2 U then d'
2 d ' = d
d' = d /2
So the distance between plates will be half on initial distance.
