Answer: Both A and B
Explanation:
The objects are in contact so it would depend on the amount of force that is pressing them as to the amount of friction and it would depend on the smoothness as too the amount of friction that is added
Move the decimal point to:
Left : (if the exponent of ten is a negative number -) ... OUR CASE HERE (-2)
or to
Right : (if the exponent is positive +).
You should move the point as many times as the exponent indicates.
Do not write the power of ten anymore.
So, standard form is:
Two points to the left {Exponent of Ten is Negative (-2)}
0.059 ... (without the 10)
Explanation:
Question 1
1.The wires are made of conducting materials e.g copper
2. A light bulb is made of filament material e.g tungsten with gases enclosed in a glass material
3.The lens is made of transparent glass material
4 The reflector is made of plastic with silver lining
5. The exterior casing of most flash lights are made of plastic
Question 2.
1.Copper is used to conduct electric current from the battery to the bulb
2.The tungsten filament ignite the gases and causes it to glow
3. The lens covers the lamp on your flashlight so that the glass on the lamp
/bulbs does not get broken.
4.The reflector redirects the light rays from the lamp, creating a steady beam of light, which is the light you see emitting from the flashlight.
5. The exterior cases houses the entire assembly and makes the flash light handy for use
Acceleration of car is 4m/s²
Acceleration of truck is 2m/s²
Explanation:
Given parameters:
Force on the car and truck = 12000N
Mass of car = 3000kg
Mass of truck = 6000kg
Unknown:
Acceleration of car = ?
Acceleration of truck = ?
Solution:
Force is product of mass and acceleration. It is a push or a pull exerted on a body.
Force = mass x acceleration
Make acceleration the subject of the formula;
Acceleration = 
Acceleration of car = 
= 4m/s²
Acceleration of truck = 
= 2m/s²
