B.) Venus and Uranus
All of the planets move in an eastward direction except Venus and Urunus
Answer:
75457.54816 N
Explanation:
= Initial force
= Weight of car = 11547.83 N
= Smaller radius = 5 cm
= Larger radius = 19.56 cm
From Pascal's law we have
![\dfrac{F_1}{A_1}=\dfrac{F_2}{A_2}\\\Rightarrow F_1=F_2\dfrac{A_1}{A_2}\\\Rightarrow F_1=11547.83\dfrac{\pi r_1^2}{\pi r_2^2}\\\Rightarrow F_1=11547.83\dfrac{5^2}{19.56^2}\\\Rightarrow F_1=754.57548\ N](https://tex.z-dn.net/?f=%5Cdfrac%7BF_1%7D%7BA_1%7D%3D%5Cdfrac%7BF_2%7D%7BA_2%7D%5C%5C%5CRightarrow%20F_1%3DF_2%5Cdfrac%7BA_1%7D%7BA_2%7D%5C%5C%5CRightarrow%20F_1%3D11547.83%5Cdfrac%7B%5Cpi%20r_1%5E2%7D%7B%5Cpi%20r_2%5E2%7D%5C%5C%5CRightarrow%20F_1%3D11547.83%5Cdfrac%7B5%5E2%7D%7B19.56%5E2%7D%5C%5C%5CRightarrow%20F_1%3D754.57548%5C%20N)
The force is 754.57548 N
<u>Answer;</u>
<em>D. The object’s weight changes, but its mass stays the same.</em>
<u>Explanation;</u>
- Mass is the amount of matter in a object, which is measured in kilograms. Mass of an object is measured using a beam balance. It is important to note that the mass of an object or a body remains constant, and does not vary from one place to another. For instance the mass of a person on the moon will be the same as when the person is on the earth surface.
- Weight on the other hand is the measurement of gravitational pull of an object. weight is measured using a spring balance and measured in Newtons. Weight varies from one place to another depending on the gravitational pull of a given surface.
Sensors in the muscles and joints send messages back through peripheral nerves to tell the cerebellum and other parts of the brain where and how the arm or leg is moving and what position it's in
