Answer:
46 m and 159 m
Explanation:
first find initial x and y component of velocity and take final y component of velocity as zero at maximum point and follow steps as i have solved
I believe its E.
Traveling through metal, electrons can not go the speed of light
Answer:
A.
B.
C.
Explanation:
The capacitance of a capacitor is its ability to store charges. For parallel-plate capacitors, this ability depends the material between the plates, the common plate area and the plate separation. The relationship is
is the capacitance, is the common plate area, is the plate separation and is the permittivity of the material between the plates.
For air or free space, is called the permittivity of free space. In general, where is the relative permittivity or dielectric constant of the material between the plates. It is a factor that determines the strength of the material compared to air. In fact, for air or vacuum, .
The energy stored in a capacitor is the average of the product of its charge and voltage.
Its charge, , is related to its capacitance by (this is the electrical definition of capacitance, a ratio of the charge to its voltage; the previous formula is the geometric definition). Substituting this in the formula for ,
A. Substituting for in ,
B. When the distance is ,
C. When the distance is restored but with a dielectric material of dielectric constant, , inserted, we have
Homes with multiple bathrooms have outlets connected in series with a red reset button in the system. The reason for this circuit design is to prevent electrocution.
<h3>What is red reset button?</h3>
The water heater's reset switch provided on the upper thermostat of an electric water heater. If the button is on, the switch would have tripped and the reset is required.
To prevent any kind of injury or killing of a person by electric shock is called as the electrocution. This can be prevented only by outlets connected in series with a red reset button.
Thus, the reason for this circuit design is to prevent electrocution.

Answer:
3317.44401 kg/m³
Explanation:
= Actual density of cube = 1800 kg/m³
= Density change due to motion
v = Velocity of cube = 0.84c
c = Speed of light =
Relativistic density is given by
The cube's density as measured by an experimenter in the laboratory is 3317.44401 kg/m³
