It's short for magnetic levitation technology; it uses the opposite attraction of magnets to keep something in the air; e.g. a train with magnets on the bottom facing south and the tracks that also have south facing magnets.
Answer:
Explanation:
a )
If it is totally absorbed pressure is calculated as follows .
Pressure = I / c where I is intensity of light falling .
= 1000 / 3 x 10⁸
= 3.33 x 10⁻⁶ N / m²
b ) weight of tritium atom
= 3 x 1.67 x 10⁻²⁷ kg
acceleration = force / mass
= 3.33x 10⁻⁶ / 3 x 1.67 x 10⁻²⁷
= .6646 x 10²¹ m /s²
= 66.46 x 10¹⁹ m / s²
Answer: 750Kg
Explanation:
Recall that force is the product of the mass M, of an object moving at a uniform acceleration.
i.e Force = Mass x Acceleration
In this case, Mass = ?
Force = 3.00 x 10^3 N = (3.00 x 1000N)
= 3000N
Uniform acceleration = 4.00m/s^2
Force = Mass x Acceleration
3000N = Mass x 4.00m/s^2
Mass = (3000N/4.00m/s^2)
Mass = 750Kg (The SI unit of mass is kilograms)
Thus, the mass of the car is 750Kg
Answer:
Time = 2.6 minutes
Explanation:
Given the following data;
Speed = 0.65 m/s
Distance = 15 meters
To find the time to get to the canteen;
Mathematically, time is given by the formula;
Time = distance/speed
Substituting into the formula, we have;
Time = 15/0.65
Time = 23.08 seconds
To minutes = 60/23.08 = 2.6 minutes
