Answer:
The x component of this vector is (-1î) unit
Explanation:
Vector position of point 1 = x₁ = 5 (cos (-π/3)î + sin (-π/3)j) = (2.5î - 4.33j)
Vector position of point 2 = x₂ =3(cos 60°î + sin 60°j) = (1.5î + 2.598j)
Vector joining the two point, x₁₂ = x₂ - x₁ = (1.5î + 2.598j) - (2.5î - 4.33j) = - 1.0 î + 6.928j
The x component of this vector is -1î unit.
Since fundamental units are elementary in nature and cannot be reduced further, so it can not be reduced further, so it cannot be expressed in other units
The repeated rising and sinking of water during boiling is due to convection. It <span>is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it. Hope this answers the question.</span>
Power = current x voltage
So the power is 7 x 110 = 770 W = 0.77kW
0.77 x 13 = 10.01 kWh
10.01 x 10 cents = 100.1 cents (is this 1 dollar? Idk I use a different currency)
Answer:
0.5 mph in the opposite direction
Explanation:
= Mass of Cadillac = 1000 kg
= Velocity of Cadillac = 1 mph
= Mass of Volkswagen = 2000 kg
= Velocity of Volkswagen
In order to know the speed the system must have the momentum exchange
As the linear momentum of the system is conserved
The speed of the impact is given by 0.5 mph in the opposite direction
