Well, to be broken down, resistance is the opposition that a substance offers to the flow of an electric current.
What would happen to a light bulb if the voltage increased, but the resistance stayed the same would be this:
The current, being directly proportional to the voltage, would increase, causing the light bulb to increase I'm brilliance, which means: it would simply become brighter.
Hope I helped you out!
Answer:
2.94 x 10⁵ Pa
Explanation:
m = mass of the car supported by four ires = 1200 kg
g = acceleration due to gravity = 9.8 m/s²
A = Area of contact for each tire = 100 cm² = 100 x 10⁻⁴ m²
n = Number of tires
P = Gauge pressure
Using equilibrium of force in vertical direction
n P A = mg
4 P (100 x 10⁻⁴) = (1200) (9.8)
P = 2.94 x 10⁵ Pa
Answer:
New acceleration is 20.0 m/s².
Explanation:
F = m*a
F = 0.35 kg * 10.0m/s²
If Force will be doubled , and mass will be the same
we can write
2F = 2*0.35 kg*10.0 m/s²=0.35kg*20.0m/s²
New acceleration is 20.0 m/s².
Explanation:
I assume the acceleration calculated in part (b) is the 3.33 m/s² from your other question.
Use Newton's second law to find the total force:
F = ma
F = (60,000 kg) (3.33 m/s²)
F = 200,000 N
Since there are 2 engines, the thrust from each is half of this:
F = 100,000 N
In reality, there are forces other than thrust. There are also drag forces (rolling friction and air resistance).
From Newton's second law, if we increase the mass and keep the force the same, the acceleration decreases. So it would take longer to reach the take-off speed.
