Answer:
Because water mixes with the dirt when it rains to make that mud when the mud is left in the sun, the sun <em>Evaporates</em><em> </em>that water, and eventualy it will turn into sand.
Answer:
a = 16 m/s²
Explanation:
The mass of the object, m = 200 kg
The radius of the circular motion, r = 4 m
The speed of the object, v = 18 m/s
The centripetal acceleration is given by the relation,
a = v²/r
Substituting the given values,
a = 18 / 4
= 16 m/s²
Hence, the centripetal acceleration of the object is, a = 16 m/s²
Out of the choices provided I would choose B, this is because A is wrong due to simple machines making our work easier and require less energy, C is wrong due to the work actually being done faster due to simple machines. Now D and B felt like they were both correct but D just doesn't make much since when you apply it to the topic of Simple machines so I found B.
Answer:
Electric potential, E = 2100 volts
Explanation:
Given that,
Electric field, E = 3000 N/C
We need to find the electric potential at a point 0.7 m above the surface, d = 0.7 m
The electric potential is given by :
V = 2100 volts
So, the electric potential at a point 0.7 m above the surface is 2100 volts. Hence, this is the required solution.
Answer:
Combustion chamber
Expalnation
Gasoline engine,
Gasoline engine is a type of internal-combustion engines in this engine when in the combustion chamber air and fuel mixture is burned with ignition initiated by an electric spark that time power is generated.
