Answer:

Newton believed that mass tells gravity how much force to exert. Einstein believed that mass tells space-time how to curve.

Explanation:

Isaac Newton believed that bodies on earth had a force of gravity pulling them down as a result of their masses.

Albert Einstein believed that the bodies were not pulled down but were moving around in a circular sphere/manner.

This confirms Newton believing that mass tells gravity how much force to exert and Einstein believing that mass tells space-time how to curve.

Satellites, A and B, each of mass m, are to be launched into circular orbits about Earth's center. Satellite A is to orbit at an

Volgvan

Answer:

0.63

Explanation:

We are given that

Radius of earth, $R_E=6370 km$

Radius of orbit A, $R_A=7590+6370=13960 km$

Radius of orbit B, $R_B=6370+15800=22170 km$

We have to find the ratio of the potential energy of satellite B to that of satellite A in orbit.

Potential energy of orbit A= $U_A=-\frac{GM}{R_A}=-\frac{GM}{13960}$

Potential energy of orbit B= $U_B=-\frac{GM}{R_B}=-\frac{GM}{22170}$

$\frac{U_B}{U_A}=\frac{13960}{22170}=0.63$

Hence,the ratio of the potential energy of satellite B to that of satellite A in orbit=0.63

KATRIN_1 [288]

Answer:

T = 1.73 kg

Explanation:

Let's use Newton's second law for this balance problem

We draw a coordinate system with the x axis parallel to the plane and the Y axis perpendicular

The only force we have to lay down is the weight (W)

Wx = W sin θ

Wy = W cos θ

Wx = 2.0 ain 60

Wx = 1.73 kg

Wy = 2.0 cos 60

Wy = 1.0 kg

Y Axis

N-Wy = 0

X axis

T- Wx = 0

T = Wx

T = 1.73 kg
