Explanation:
Given that,
An ideal horizontal spring-mass system oscillates with a period of 0.60 seconds.
Mass is 3 kg but the spring constant is not known. We need to find the frequency of oscillations when this same spring and mass are arranged to hang vertically. We know that the relation between frequency and time period is inverse. Frequency is given by :
Hence, the correct option is (d) "none of the above".
Answer:
The Questions are
a. Calculate the x-component of the electric field, in newtons per coulomb
b. Calculate the y-component of the electric field, in newtons per coulomb
c. Calculate the z-component of the electric field, in newtons per coulomb
d. Calculate the magnitude of the electric field, in newtons per coulomb.
Explanation:
Given that,
Φx= 85 N•m2/C. X direction
Φy= -85 N•m2/C. Y direction
Φz = 0. Z direction
Radius of loop =3cm=0.03m
Surface area of the circle is πr²
A=22/7×0.03²
A=0.00283m²
Flux is given as Φ=EA
a. Φx=ExA
Ex=Φx/A
Ex=85/0.00283
Ex=30035.33N/C
b. Ey=Φy/A
Ey=-85/0.00283
Ey=-30035.33N/C.
c. Ez=Φz/A
Ez, =0/A
Ez=0N/C
d. Magnitude of E.
E=√Ex²+Ey²+Ez²
E=√(30035.33)²+(-30035.33)²
E=42476.38N/C.
Answer:
Explanation:
Data given
represent the applied force by the wheel
represent the radius for the wheel
represent the rotational speed given
represent the kinetic friction coeffcient given.
Solution to the problem
For this case we need to find first the spped with the usual units in m/s like this:
And we can replace the values given and we got:
Now we can calculate the friction force, for this case we assume that the normal force is the force exerted by the wheel and from the definition:
Now we can calculate the power assuming that all the energy is converted to kinetic energy from the motor with the following formula:
And we can replace with the values that we found:
And that would be the energytransferred from the motor driving the wheel to the thermal energy of the wheel and tool and to the kinetic energy of the material thrown from the tool.
The safety contract will include basic lab safety guidelines such as:
- Remove all flammable materials from the work station.
- Avoid leaving the heating set-up unattended.
- Fold long sleeves, tie back long hair, remove all accessories that may catch on fire.
- Wear proper lab attire.
- Avoid horse-playing in the lab.
- Report any injuries to the teacher, no matter how minor, as soon as possible.
- Avoid working alone inside the lab.
- Make sure you are aware of the location of the safety equipment and features of the lab especially the first aid kit, fire exit, fire blanket, and fire extinguisher.
- Follow instructions carefully.
- Dispose materials properly.
- Report any faulty equipment as soon as possible.
- Avoid touching hot surfaces with bare hands.
- Wash all used glassware.
- Keep workstation clean and tidy to avoid accidents.
- Avoid eating and drinking inside the lab.
- Put away unnecessary things. Only materials needed for the investigation must be on the workstation.
Further Explanation:
In his safety contract, Chris will find statements that has him agreeing that he will behave appropriately inside the lab especially since they will be working with an open fire (Bunsen burner) or a heating equipment (hot plate) to change the temperature of the water. Proper behavior and basic expectation inside a lab are in the items listed above.
