How would gravity cause planets to move if they did not have inertia?

daser333 [38]

I’d think the answer would be C. i’m just kinda guessing but my thought process is this (as simply as i can put it because physics is confusing):

so for example say you throw a ball across a flat surface. inertia is what keeps the ball rolling straight in a line, so unless you were to maybe put your hand in front of the ball or something, it would just go straight forever.

this is what happens with the planets. they go in a straight line, but since there’s gravity, the planets are also being pulled towards the sun. so gravity and inertia are why the planets orbit in the circle pattern they do. so when we remove inertia, we’re removing the state in which the planets keep going straight while being pulled towards a center point (the sun). this causes gravity to be the only factor in the planets orbiting. so that being said, the planets would just be pulled towards the sun. :)

Light from a 504-nm monochromatic source is incident upon the surface of fused quartz (n = 1.56) at an angle of 17°. What is the

PilotLPTM [1.2K]

Answer:

73 degree

Explanation:

Angle of incidence = 17 degree

According to the laws of reflection, the angle of incidence is equal to the angle of reflection.

So, angle of reflection = 17 degree

Angle from the surface = 90 - 17 = 73 degree

Answer:

The speed was 26.91m/s (96.9 km/h)

Explanation:

Here you have to consider that at the beginning you have an amount of kinetic energy (K) that is dissipated because of the work done by friction forces (T). Since the car is stopped after the accident, all the energy has been dissipated. Thus, $K=T$ .

The definition of the kinetic energy is $K=1/2*m*v^2$ .

The work done by the friction forces is: $T=f*(m*g)*d$ . Where f is the friction coefficient, g is the gravity acceleration, m is the mass of the car and d is the skid marks longitude. Therefore,
