Answer:
Δx = 1.2 m
Explanation:
The CHANGE of spring length) (Δx) can be found using PS = ½kΔx²
Δx = √(2PS/k) = √(2(450)/650) = 1.17669... ≈ 1.2 m
The actual length of the spring is unknown as it varies with material type, construction method, extension or compression, and other variables we have no clue about.
The sun was shining on the sand heating it up causing ot to become hot
Answer:
it increases-
Explanation:
When the mass of a rocket decreases as it burns through its fuel and the force ( thrust) is constant then by newtons second law of motion
F= ma here F is constant this means that ma= constant
⇒ m= F /a this implies that mass is inversely proportional to acceleration.
its means when the mass decreases the acceleration must increase. hence the acceleration increases
Answer:
I = 0.451 amp
Explanation:
given,
C = 8.0 µF
V = 2 V
resistor connected between two terminal = 6 Ω
current flowing through resistor = 13 µsec
Q = CV
Q = 8 x 2
Q = 16 µC
for an RC discharge circuit
V = V_0e^{-\dfrac{t}{RC}}
I = \dfrac{-Q_0}{RC}e^{-\dfrac{t}{RC}}
t = 13 µsec
I = \dfrac{-16}{6\times 2}e^{-\dfrac{13}{6\times 2}}
I = 0.451 amp
neglecting -ve sign just to show direction.
Answer:
A typical white dwarf is about as massive as the Sun, yet only slightly bigger than the Earth.
Explanation:
A typical white dwarf is about as massive as the Sun, yet only slightly bigger than the Earth.
White dwarfs are one of the densest elements in the universe, surpassed only by neutron stars and black holes. They can be considered as medium mass stars that fuses hydrogen into helium
