Answer:
3.42N
Explanation:
*not too sure bc i left my physics notes at school so it might not be 100% accurate :p*
Use the equation: F = (GMm)/(r^2)
F = force of gravity
G = gravitational constant (6.7x10^-11)
M = mass1 (2.5x10^30kg)
m = mass2 (1kg)
r = radius (7000m)
Plug it in: F = ((6.7x10^-11)(2.5x10^30)(1)) / (7000^2)
F = (1.675x10^20) / (4.9x10^7)
F = 3.4183673x10^12
F = 3.42N

To reduce friction between two surfaces, you have to
make the surfaces smoother.
The best way to do that is to introduce a fluid between them,
like grease, oil, or air.
Answer:
option A
Explanation:
When white light is incident on prism it bends and dispersed into different colors.
According to Cauchy equation, refractive index is inversely proportional to the wavelength of the light.
wavelength of the light in decreasing order
orange > yellow > green > blue
wavelength of the orange light is the highest.
Hence, the refractive index of orange will be lowest.
The correct answer is option A
