At low wind speed, more blades will be better and the blades should be long and wide. The blade pitch should be large. At high wind speed, the blades should be short and thin. The blade pitch should be small then.
Answer
given,
mass of an object = 5 Kg
mass of the other object = 5.98 x 10²⁴ Kg
radius of earth = 6371 Km = 6.371 x 10⁶ m
comparison between gravitational force between two object and weight of the object.
gravitational force between two objects
F = 49.134 N
weight of the object on the earth surface
F = m g
F = 5 x 9.81
F = 49.05 N
From the above two calculation we can conclude that gravitational force is approximately equal to weight of the body.
Explanation:
<u>Ionized gases are found in very high - temperature environment -
</u>
In order to ionize a gas , i.e. to pull out an electron from a neutral atom , to form an ion .
The process of ionization require high amount of energy to remove the electron from the outer most shell of the atom .
The amount of energy for the process of ionization is only possible in high - temperature regions .
Answer:
Please see the direction of force in the attachment
Explanation:
As the particle enters the capacitor, it experiences electric. In order to move in the same direction as the electron was moving before entering the capacitor, the force due to the electric field of capacitor must be balanced by the magnetic field.
The direction of particle is shown in the attachment.
As we know,
Force = q (v *B)
Yea, im pretty sure they mean the same.
