Answer:
The best reason for the increased risk of cardiovascular diseases in women after menopause is the significant decrease in the levels of Estrogen in the body.
Detailed answer:
- Due to the approach of menopause the estrogen levels in the blood decrease drastically.
- Estrogen helps in relaxing the vessels and keeping them in their natural diameter.
- But due to a drastic decrease in its level due to menopause, there is a high chance of cholesterol building up on the walls of the artery in the heart, which can cause many cardiovascular diseases.
Answer:
1.3 m/s
Explanation:
(300N of Fa + 100N' of Fa) - 140N of Ff /200Kg
400N of Fa - 140N* of Ff
260 of ∑F/ 200kg = acceleration
a of piano = 1.3 m/s²
Answer: 1666J
Explanation:
Given that,
Mass of box (m) = 10kg
Total distance covered by box (h)
= (5m + 12m)
= 17m
work done on the box = ?
Work is done when force is applied on an object over a distance. Hence, the magnitude of work done on the box depends on its mass (m), distance covered (h), and acceleration due to gravity (g)
(g has a value of 9.8m/s²
i.e Work = mgh
Work = 10kg x 9.8m/s² x 17m
Work = 1666J
Thus, 1666 joules of work was done by the woman on the box.
