Answer:

-0.038 N

Explanation:

F=K Q1 Q2/r^2 by COULOMB'S LAW

F= 9×10^9×1×10^-5×-1.5×10^-5/(6)^2

F= -0.038 N

Does the sun always shine directly overhead at the equator at noon
Nikitich [7]
The sun always shines directly overhead at noon. This is because the equator always gets the equivalent amount of sunlight. The area always get 12 hours of sunlight, because it's 0 degrees north and south and it's at the center of the Earth.

A dog barks to alert his owner. What is the medium for the sound waves produced by the dog barking?
777dan777 [17]

Answer:

The medium for the sound waves produced by the dog barking is the air

Explanation:

Sound waves are a form of mechanical waves such that it moves from one point to another by the vibration, back and forth of the medium particles from one layer to the next, thereby the particles of the medium remain in the same location and only the wave energy is propagated

The medium which has particles that vibrate back and forth in order to transmit the barking of the dog is the air.

In which process will the internal energy of the system NOT change? a. An adiabatic expansion of an ideal gas.
marusya05 [52]

Answer:

B. An isothermal compression of an ideal gas.

Explanation:

The internal energy of an ideal gas is just function of the temperature; it does not matter what other thermodynamic property changes, if the temperature does not change, the internal energy neither does. That is just for ideal gases; real gases behaviour is not like that. All of the other options bring with them an increase or decrease of the temperature:

For A, the temperature will decrease because the gas will do work as it expands, converting part of his internal energy to work.

For C, the temperature will increase, because given PV=nRT, if the volume increases (expansion) and the pressure is constant, the temperature must increase to satisfy the equation.

9. What is the total kinetic energy (KEtran + KErot) of a solid cylinder with mass M = 2.50 kg and radius R = 0.5 m that rolls w
GarryVolchara [31]

Answer:

110.25 J

Explanation:

We are given that

Mass,M=2.5 kg

Radius,R=0.5 m

Distance,d=4.5 m

Initial speed,u=0

We have to find the total kinetic energy

According to law of conservation of energy

Total kinetic energy=Potential energy=mgh

Where g=9.8m/s^2

Using the formula

Total kinetic energy=2.5\times 9.8\times 4.5

Total kinetic energy=110.25 J
