Answer:
mass
Explanation:
As this is directly related to inertia. Inertia is the property of unit which resists the change of state of rest or motion
Answer:
the speed acquired by the man is: ![0.00308\,\,\frac{m}{s}](https://tex.z-dn.net/?f=0.00308%5C%2C%5C%2C%5Cfrac%7Bm%7D%7Bs%7D)
Explanation:
Use conservation of linear momentum to solve this problem, and make sure you start by converting the 63 g stone mass into kilograms = 0.063 kg.
Now from conservation of linear momentum, the momentum imparted to the stone (which is the product of the stone's mass time its speed) must equal in magnitude that of the 90 kg man. Then we need to find the unknown speed of the man:
![m_1\.v_1=m_2\,v_2\\0.063\,(4.4)\,\frac{kg\,m}{s} =v_2\,(90\,\,kg)\\0.2772\,\frac{kg\,m}{s}=v_2\,(90\,\,kg)\\v_2=\frac{0.2772}{90} \,\frac{m}{s} \\v_2=0.00308\,\,\frac{m}{s}](https://tex.z-dn.net/?f=m_1%5C.v_1%3Dm_2%5C%2Cv_2%5C%5C0.063%5C%2C%284.4%29%5C%2C%5Cfrac%7Bkg%5C%2Cm%7D%7Bs%7D%20%3Dv_2%5C%2C%2890%5C%2C%5C%2Ckg%29%5C%5C0.2772%5C%2C%5Cfrac%7Bkg%5C%2Cm%7D%7Bs%7D%3Dv_2%5C%2C%2890%5C%2C%5C%2Ckg%29%5C%5Cv_2%3D%5Cfrac%7B0.2772%7D%7B90%7D%20%5C%2C%5Cfrac%7Bm%7D%7Bs%7D%20%5C%5Cv_2%3D0.00308%5C%2C%5C%2C%5Cfrac%7Bm%7D%7Bs%7D)
therefore the speed acquired by the man is: ![0.00308\,\,\frac{m}{s}](https://tex.z-dn.net/?f=0.00308%5C%2C%5C%2C%5Cfrac%7Bm%7D%7Bs%7D)
Answer:
The potential between the plates will decrease.
Explanation:
An insulator is usually placed between the parallel plates and is also called a dielectric because it makes the amount of charge a capacitor can accommodate to increase at a particular potential difference.
Furthermore, the dielectric effect will make the electric field of the charged capacitor which is not connected to a source of supply to decrease.
Now, when the battery is removed, the charge Q remains constant and Capacity C will increase.
Formula for the potential difference is here;
V = Q/C
Since the numerator Q is constant and the denominator C increases, it means the potential difference V will decrease
The right answer is true because particles are allowed to freely move in gases but in liquids the particles can not leave the other particles, they may move freely but with other particles but gas particles can be found individually roaming around
