A tiltmeter is an object to measure small movements.
The answer is no. The formula for density is <span>p=m/V. Everything about the lemonade stays the same except the container it was in. And because the lemonade itself did not change in any way the density of it stays the same.</span>
Answer:
Only there will be a change in density of sun.
Explanation:
As your question says only the radius of sun is decreased and there is no change in the mass. So it means that the center of gravity will be the same and as a result the gravitational force remains the same. Only the density of sun changes as it shrinks.
a) gia tốc = vf-vi / t
a = 14-10 / 20
a = 0,2ms⁻²
b) dưới dạng a = Δv / t
v = lúc
v = 0,2 × 40
v = 8ms⁻¹
như v = d / t
do đó d = vt
d = 8 × 40
d = 320m
