Answer:
The answer is E) 20kPa
Explanation:
Here we use the definition of Pressure: Pressure is a physical quantity that measures the projection of force in the perpendicular direction per unit area. In this case, wehave a 200N Force over a 100cm^2 Area
In order to have the pressure in international units we need to convert those cm^2 to m^2 this way:
We know 100cm is equal to 1m
In this case, the area will be equal to 0,01m^2
With this information we use the Pressure equation, which based on the definition will be:
Solving:
Then P is the same as 20kPa
Answer:
9833333.33 years
Explanation:
Speed of the land = 6 cm/y = v
Convert the speed to km/y
1 km = 10000 m
⇒1 m = 1/10000 km
⇒1 m = 10⁻⁵ cm
So,
6 cm/y = 6×10⁻⁵ km/y
Distance the land will travel = 590 km = s
Time taken
∴ Time taken by the land to move 590 km is 9833333.33 years.
Answer:
It takes 11.20 ms for the sphere to increase in potential by 1260 V
Explanation:
Using the formula q = It where I is current in Ampere, and t is in seconds
q = ( 1.000002 - 1.0000000) t
q = 0.000002t
Voltage on the surface of the sphere V = Kq / r
where K is 9.0 × 10⁹ N².m² / c² and
R = 16 cm = 16 /100 = 0.16m
V = Kq /r
substitute the value into q
V = K(0.000002t) / r
cross multiply
rV = K × 0.000002t
make t subject of the formula
t = 0.16 × 1260 / ( 9×10⁹ × 0.000002)
t = 201.6 / ( 18 × 10³)
t = 0.0112 s
= 11.20 ms
It takes 11.20 ms for the sphere to increase in potential by 1260 V
