Answer:
No, it is independent
Explanation:
As we know that car is moving horizontally
so the vertical component of the speed is zero initially
so in order to hit the ground we know that
so here we know that
on solving above equation for time
so we will say that it will not depends on the initial horizontal speed
A negative charge i guess
Answer;
= 4.49 g/cm³
Explanation;
Density = Mass / Volume
mass = 1.41 kg,
volume = 0.314 L
but; 1 kg = 1000 g and 1 L = 1000 mL
Thus;
Density = 1.41 kg/0.314L
Density = 4.49 kg/L (1000g/ 1kg)(1L/1000cm^3)
Density = 4.49 g/cm^3
Answer:
★The second law of refraction
The ratio of sine of angle of incidence to the sine of angle of refraction is a constant for a light of given colour and for a given pair of media. This law is also called Snell's law of refraction. If 'i' is the angle of incidence and 'r' is the angle of refraction then, Sin i/Sin r = constant
This constant value is called the refractive index of the second medium with respect to the first.
