Explanation:
Hey there!!
Here,
Weighs = 65n
Gravity = 10n
We know that,
weighs = mass × gravity.
65 = m × 10
![m = \frac{65}{10}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B65%7D%7B10%7D%20)
Therefore the mass is 6.5 kg.

a) 32.3 N
The force of gravity (also called weight) on an object is given by
W = mg
where
m is the mass of the object
g is the acceleration of gravity
For the ball in the problem,
m = 3.3 kg
g = 9.8 m/s^2
Substituting, we find the force of gravity on the ball:
![W=(3.3)(9.8)=32.3 N](https://tex.z-dn.net/?f=W%3D%283.3%29%289.8%29%3D32.3%20N)
b) 48.3 N
The force applied
![F_{app} = 36 N](https://tex.z-dn.net/?f=F_%7Bapp%7D%20%3D%2036%20N)
The ball is kicked with this force, so we can assume that the kick is horizontal.
This means that the applied force and the weight are perpendicular to each other. Therefore, we can find the net force by using Pythagorean's theorem:
![F=\sqrt{W^2+F_{app}^2}](https://tex.z-dn.net/?f=F%3D%5Csqrt%7BW%5E2%2BF_%7Bapp%7D%5E2%7D)
And substituting
W = 32.3 N
Fapp = 36 N
We find
![F=\sqrt{32.3^2+36^2}=48.3 N](https://tex.z-dn.net/?f=F%3D%5Csqrt%7B32.3%5E2%2B36%5E2%7D%3D48.3%20N)
c) ![14.6 m/s^2](https://tex.z-dn.net/?f=14.6%20m%2Fs%5E2)
The ball's acceleration can be found by using Newton's second law, which states that
F = ma
where
F is the net force on an object
m is its mass
a is its acceleration
For the ball in this problem,
m = 3.3 kg
F = 48.3 N
Solving the equation for a, we find
![a=\frac{F}{m}=\frac{48.3}{3.3}=14.6 m/s^2](https://tex.z-dn.net/?f=a%3D%5Cfrac%7BF%7D%7Bm%7D%3D%5Cfrac%7B48.3%7D%7B3.3%7D%3D14.6%20m%2Fs%5E2)

Explanation:
Color of third band of a coded resistor is Brown.
What is Resistance:
- Resistance is a measure of the opposition to current flow in an electrical circuit.
- Resistance is measured in ohms, omega (Ω)
The color code specify the resistance value, the tolerance, and sometimes the reliability or failure rate.
How to identify resistor's color codes:
- Look at the resistor so the group of 3 or 4 color bands are on the left side
- Read the color bands from left to right.
- Read the color on the last color band, which is farthest right.
- compare the colors to the resistance code table
Here,
the value of resistance is 2.3x10^2 Ω
R = 23x10^1 Ω
here power of 10 is 1
so, the color of third band of a color coded resistor will be related to number 1
Hence,
color of third band of a coded resistor is Brown.
