Answer:
According to Newton's second law of motion, an object with a heavier mass will have more acceleration than an object with a smaller mass if both objects are moving with the same speed.
Explanation:
F=ma
a=F/m
a∝1/m
mass of any object is inversely proportional to its acceleration.
hence proved, an object with a heavier mass will have more acceleration than an object with a smaller mass if both objects are moving with the same speed.
Explanation:
Snell's law (also known as Snell–Descartes law and the law of refraction) is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other waves passing through a boundary between two different isotropic media, such as water, glass, or air.
Answer:
I would say the net force acting on the car is in the opposite direction of the car's motion is correct
Answer:
D Magnesia
Explanation:
Ore particles Fe3O4 (magnetite) were found in the region called Magnesia.
Magnesia was an antic city in Asia, named after the inhabitants of Greek Magnesia.
Magnetite is used as an ore, abrasive, in paint production, electrophotography, as a micronutrient fertilizer, and as a high-density concrete aggregate.
The turn and voltage ratio of a transformer can be simply expressed by the equation:
Ns/Np = Vs/Vp; where N is the number of turns and V is the voltage.
Plugging in the given values, we have:
25 turns / 100 turns = Vs / 40 volts
Vs = 40 volts (25 turns/100 turns)
Vs = 10 volts
The answer is D.
