Answer:
C. 0 N
Explanation:
In the absence of external forces, a body in motion will stay in motion.
F = ma
F = 6.0(0) = 0
D, electron, the nucleus is not a single particle to begin with, the proton has a positive charge, a neutron has a neutral charge or no charge, and an electron has a negative charge
To solve this problem we will apply Ohm's law. The law establishes that the potential difference V that we apply between the ends of a given conductor is proportional to the intensity of the current I flowing through the said conductor. Ohm completed the law by introducing the notion of electrical resistance R. Mathematically it can be described as
![V = IR \rightarrow R = \frac{V}{I}](https://tex.z-dn.net/?f=V%20%3D%20IR%20%5Crightarrow%20R%20%3D%20%5Cfrac%7BV%7D%7BI%7D)
Our values are
![I = 500mA = 0.5A](https://tex.z-dn.net/?f=I%20%3D%20500mA%20%3D%200.5A)
![V = 37V](https://tex.z-dn.net/?f=V%20%3D%2037V)
Replacing,
![R = \frac{V}{I}](https://tex.z-dn.net/?f=R%20%3D%20%5Cfrac%7BV%7D%7BI%7D)
![R = \frac{37}{0.5}](https://tex.z-dn.net/?f=R%20%3D%20%5Cfrac%7B37%7D%7B0.5%7D)
![R = 74 \Omega](https://tex.z-dn.net/?f=R%20%3D%2074%20%5COmega)
Therefore the smallest resistance you can measure is ![74 \Omega](https://tex.z-dn.net/?f=74%20%5COmega)
Answer:
6.1328 kg
60.16284 N
Explanation:
r = Radius of ball = 0.11 m
= Density of fluid =
(Assumed)
g = Acceleration due to gravity = 9.81 m/s²
m = Mass of ball
V = Volume of ball = ![\frac{4}{3}\pi r^3](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3)
The weight of the bowling ball will balance the buouyant force
![W=F_b\\\Rightarrow mg=V\rho g\\\Rightarrow m=\frac{V\rho g}{g}\\\Rightarrow m=V\rho\\\Rightarrow m=\frac{4}{3}\pi 0.11^3\times 1.1\times 10^3\\\Rightarrow m=6.1328\ kg](https://tex.z-dn.net/?f=W%3DF_b%5C%5C%5CRightarrow%20mg%3DV%5Crho%20g%5C%5C%5CRightarrow%20m%3D%5Cfrac%7BV%5Crho%20g%7D%7Bg%7D%5C%5C%5CRightarrow%20m%3DV%5Crho%5C%5C%5CRightarrow%20m%3D%5Cfrac%7B4%7D%7B3%7D%5Cpi%200.11%5E3%5Ctimes%201.1%5Ctimes%2010%5E3%5C%5C%5CRightarrow%20m%3D6.1328%5C%20kg)
The mass of the bowling ball will be 6.1328 kg
Weight will be ![6.1328\times 9.81=60.16284\ N](https://tex.z-dn.net/?f=6.1328%5Ctimes%209.81%3D60.16284%5C%20N)
Sound waves move through molecules. When there are no molecules in a certain space, sound cannot travel - whether in a vacuum or in space.
