Brown Bears Can Weigh Half A Ton (500 Kilograms). The Piston On The Left Has A Cross-sectionalarea Of

Answers

Answer 1

In order to lift the Bear, a force of 1226.25 N has to be exerted on the left piston,

What is pressure is on the piston carrying the Bear?

The pressure on the piston carrying the Bear is calculated as follows:

Pressure = force/area

Force of the Bear = 500 kg * 9.81 m/s² = 4905 N

Pressure on the right piston = 4905 N / 4 m² = 1226.25 N/m²

To lift the Bear, the pressure on  both sides must be equal.

Force to be applied on the left piston = pressure * area

Force = 1226.25 N/m² * 1 m² = 1226.25 N

Therefore, a force of 1226.25 N has to be exerted on the left piston to lift the bear.

​

Answers

Answer:

mark me brailinist

Explanation:

Dowry is a social evil in the society, that has caused unimaginable tortures and crimes towards women. The evil has taken lives of women from all stratas of society - be it poor, middle class or the rich. However it is the poor who succumb and fall prey to it, more due to their lack of awareness and education.

It is because of the dowry system, that daughters are not valued as much as the sons. In the society, many a times it has been seen that they are seen as a liability and are often subjected to subjugation and are given second hand treatment may it be in education or other amenities.

Today the government has come up with many laws and reforms, not only to eradicate the dowry system, but also to uplift the status of the girl child by bringing in many schemes.

It is now for the society at large to become aware and understand the situation. It up to all of us to take active steps in bringing about the necessary change and stop either giving or taking dowry. We must all know that we should start valuing our daughters first, so that others know their value once they grow up.
