The answer is (a) because movement is acceleration
Answer:
book speed is 3.99 m/s
Explanation:
given data
mass m = 490 g = 0.490 kg
compressing x = 7.10 cm = 0.0710 m
spring constant k = 1550 N/m
to find out
book speed
solution
we know energy is conserve so
we can say
loss in spring energy is equal to gain in kinetic energy
so
..................1
put here value
v = 3.99 m/s
so book speed is 3.99 m/s
Answer:
But the Sun isn't actually yellow; it's just an illusion caused by the Earth's atmosphere. The powerful processes happening inside the Sun are so robust that it emits every color of light imaginable. Together, these colors form a pure white light, which is precisely what you'd see from space.

The Biggest star in our universe is the sun. Although the largest in the galaxy is the <span>VY Canis Majoris which is about 3,900 to 5000 light years away from us.</span>
P₁V₁ / T₁ = P₂V₂ / T₂
1.6 × 168 /255 = 1.3 × V₂ / 285
V₂ = 1.6 × 168 × 285 / (1.3 × 255)
V₂ = 231.095
The final volume = 231 cm³
