When the ruler is broughı near the inetal knob, it repels electrons in the metal. Electrons move away froni the ruler and down the metal rod. The knob now has a positive charge. The thin pieces of metal foil at the bottom of the metal rod now have a negative charge.
Hello!
When the Northern Hemisphere is tilted toward the sun, latitudes between the equator and 90°N (the North Pole) are experiencing summer.
Answer:
Net force required to accelerate the car is 6000 N
Explanation:
Force is calculated by the equation, F = Mass × Acceleration
This is based on Newton's Second Law of Motion which states that the force acting on an object is its mass times the acceleration of the object.
Here, mass = 3000 kg and acceleration = 2 m/s²
⇒ Force = Mass × Acceleration
= 3000 × 2 = 6000 N
⇒ F = 6000 N
⇒ M = 3000 kg
⇒ a = 2 m/s²
" 50 W " means " 50 Watts " or " 50 Joules per second ".
(500,002 J) / (50 J/sec) = <em>10,000.04 seconds</em>
(That's 2 hours 46 minutes 40.04 seconds.)
<u>Answer:</u>
area of point has more pressure.
<u>Explanation:</u>
formula's : pressure = force ÷ area
1st pressure,
200 ÷ 0.2 = 1000 Pa
2nd pressure,
200 ÷ 0.004 = 50000 Pa
<h3>Therefore the pressure on the area of the point is more.</h3>
