Answer:
Dipole
Explanation:
A pair of opposite electric charges of equal magnitude is called a(n)
The alarm is going off because the alarm has already been set to activate.
The car, because logically, a car is faster and if you do the math, 300 meters per minutes is about 17 kilometers per hour, and that is lower than the car’s 36 kilometers per hour. I would show you my work but im tired man, please mark me brainliest
The universal law of gravitation says that the gravitational force between the two masses is
<em>F</em>₁ = <em>G</em> <em>m</em>₁ <em>m</em>₂ / <em>r</em> ² = 6.0 × 10⁻⁶ N
where <em>r</em> = 12 m. When the distance between the two masses is reduced to <em>R</em> = 4 m, i.e. 1/3 of the original distance <em>r</em>, we have
<em>F</em>₂ = <em>G</em> <em>m</em>₁ <em>m</em>₂ / <em>R </em>² = <em>G</em> <em>m</em>₁ <em>m</em>₂ / (<em>r</em>/3)² = 1/9 <em>G</em> <em>m</em>₁ <em>m</em>₂ / <em>r </em>² = 1/9 <em>F</em>₁
so that the resulting gravitational force has 1/9 the first magnitude, or
<em>F</em>₂ = 1/9 (6.0 × 10⁻⁶ N) ≈ 6.7 × 10⁻⁷ N
Answer:
Change in momentum is 
Solution:
The momentum of any body is the product of its mass and the velocity associated with the body and is generally given by:
Now, as per the question:
Mass of the car, M = 1500 kg
The velocity in the east direction, 
The velocity in the north direction, 
Now, the momentum of the car in the east direction:
Now, the momentum of the car in the north direction:
Change in momentum is given by:
Now,
(Since, 
)
