Expert Solution

1. Clocks in a stronger gravitational field will tick slower than clocks in a weaker gravitational field.

2. The Einstein equation says that spacetime curvature arises from the 4-dimensional distribution of matter and energy .

3.  A girl throws a ball over the top of a speeding car. The ball travels at a velocity v = 3 m/s,

Velocity of ball , vball = 3 m/s.

The car travels at a constant velocity of 100 km/hr.

Velocity of car , vcar = 100 km/hr

= 100 × 5/18 m/s

= 27.7 m/s

The car has a width of 3m and a length of 10 m.

Width = 3 m

Length = 10 m

Now,

Therefore the distance travel by car while the ball is passing overhead is 9 m.

In 2005, the Earth's magnetic field was about 10% weaker than it was in 1845 when German mathematician Carl Friedrich Gauss first measured it. If the magnetic field continues to weaken by 10% of its current value every 160 years, approximately when will it be half of its 1845 value? When will it be only 35% of its 1845 value? (Note that we are supposing, in this question, that after 320 years the strength of the field is 90% of...
