Answer:
The angular velocity of a person standing on the equator is approximately radians per second.
Explanation:
The Earth rotates at constant speed. From Rotational Physics, the angular velocity (), measured in radians per second, is defined by the following formula:
(1)
Where is the period of rotation of the Earth, measured in seconds.
If we know that , then the angular velocity of a person standing on the equator is:
The angular velocity of a person standing on the equator is approximately radians per second.
Answer:
2 x 10⁻¹²F
Explanation:
Capacitance is defined as the ration of charge (q) on either plates to the potential difference V between them.
C =
Where q is the charge on the plates
V is the potential difference
From the given parameters:
Charge on plate, q = 2.0 x 10⁻¹⁰C
Potential difference across the plate = 100V
Unknown parameter:
Capacitance of the system = ? = C
Solution
Capacitance = 2.0 x 10⁻¹⁰/100 = 2 x 10⁻¹²F
To get the speed of light in this class glass, used the following equation
v= c/n ; where c is the speed of light in a vacuum and n where the index of refraction
Based on my research the index of refraction of the class glass is 1.59
Given
c= 3.00 x 10^8 m/s
n= 1.59
Solution
we will use 3.00 for c to get the speed of light in class glass cause 10^8 m/s is fixed
v= 3.00 / 1.59
v= 1.886
So the speed of light in this class glass is 1.89 x 10^8 m/s
Answer:
Explanation:
Voltage of the car battery = 12.0 V
Voltage drop in the battery = 3.4 V
The remainder of the voltage is the starter voltage, that is:
Starter voltage = Initial battery voltage - voltage drop
Starter voltage = 12.0 - 3.4
Starter voltage, = 8.6 V
Current drawn by starter, = 93 A
According to Ohm's law:
Starter Resistance, =
