Western coast is frequented by the cold californian current which reduces the temperature.
Southern Alaskan coast is frequented by Warm Alaskan current which increases the temeprature of the coast.
Eastern coast is frequented by Warm Gulf Stream which increases the temperature of the coast.
Explanation:
Oceanic current (Gulf stream) increases the temperature of the coastal region along the Eastern Coast of the US mainland. Gulf stream represents the system of warm oceanic current. This current causes excessive hot conditions in the US mainland.
West Coast of the US is frequented by Cold Californian current and warm Alaskan current. Hence, the Californian current decreases the temperature of the western coast of the US and cause atmospheric stability in the region.
Southern Alaska is frequented by the warm Alaskan current which raises the temperature of the southern Alaskan coast.
Answer:
Explanation:
The mass of vented out in one day is:
Answer 1: minimum required flow rate of fresh air is 0.57 m^3/ses
Explanation: since the minimum requirement per person is 30 L/sec
Converting to m^3 it becomes
30/1000 = 0.03 m^3/sec
For 19 heavy smoker we will require
19 * 0.03 = 0.57m^3/sec
Answer 2: diameter of the duct will be 0.3m
Explanation: since flow rate is
Q =0.57m^3/sec
Also
Q = AV (continuity equation)
Where A is the duct area and V is the velocity of air flow in m/sec
0.57m^3/sec = A * 8m/sec
A = 0.57/8 = 0.071m^2
Area of the duct is that of a circle
A = 3.142 *(d^2 ÷4)
d^2 = (0.017 * 4)/3.142 = 0.09
d is square root of 0.09
d = 0.3m
Answer:
False
Explanation:
In electric heater electric energy is converted into heat energy. In heater wires are present which have resistance and current is flow in heater when we connect the heater to supply.
And we know that whenever current is flow in any resistance then heat is produced so in electric heaters electric energy is converted into heat energy
So this is a false statement
