Power = work/time
1000/8 = 125
Answer: 125 watts
Atomic Nuclear's significance is that it proves the idea of quantum tunneling in the branch of quantum physics. The barriers that keep nuclear energy together are very high. Quantum mechanics sometimes tells us that particles can sometimes tunnel through the walls over they cannot climb and it happens at random intervals and unpredictably.

The chemical senses are the senses of smell (olfaction) and taste (gustation).
Answer:
B. False
Explanation:
An acceleration of 9.8 m/s² means the velocity increases by 9.8 m/s every second.
Answer:
32 m and -2.4 m/s
Explanation:
Given:
v₀ = 25 m/s
t = 2.8 s
a = -9.8 m/s²
Find: Δy, v
Δy = v₀ t + ½ at²
Δy = (25 m/s) (2.8 s) + ½ (-9.8 m/s²) (2.8 s)²
Δy = 31.6 m
v = at + v₀
v = (-9.8 m/s²) (2.8 s) + 25 m/s
v = -2.44 m/s
Rounded to two significant figures, the bullet reaches a height of 32 m and a velocity of -2.4 m/s.
