Answer:
3.192 m/s
Explanation:
t = Time taken = 0.900 seconds
u = Initial velocity
v = Final velocity
s = Displacement = 1.1 meters
a = Acceleration due to gravity = 9.81 m/s²
Velocity of the elevator when it snapped is 3.192 m/s
Answer:
mass consumed by 235U each day = 2 kg
Explanation:
electrical power produced = 1 GW = 1 × 10⁹ × (6.24151 × 10¹⁸ ) eV
= 6.24151× 10²¹ MeV/s
thermal energy = 0.420 * 250 = 105 MeV
= 5.94 × 10¹⁹ fission/second
=5.94 × 10¹⁹× 24 × 60 ×60)
= 5.13 × 10²⁴ fission/day
mu = 235.04393 × 1.660× 10 ⁻²⁷ = 390.1729× 10⁻²⁷ Kg
M = mu ×5.13 × 10²⁴
= 390.1729× 10⁻²⁷ ×5.13 × 10²⁴
M = 2 kg(approx.)
mass consumed by 235U each day = 2 kg
Answer:
At (approximately
.)
Explanation:
Note that the acceleration of the car between and
(
) is constant. Initial velocity of the car was
, whereas
at
. Hence, at
, this car would have travelled a distance of:
.
At , the truck would have travelled a distance of
.
In other words, at , the truck was
ahead of the car. The velocity of the car is greater than that of the truck by
. It would take another
before the car catches up with the truck.
Hence, the car would catch up with the truck at .
