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

2. The Einstein equation says that spacetime curvature arises from the 4-dimensional distribution of ______________and _____________.

3. A girl throws a ball over the top of a speeding car. The ball travels at a velocity v = 3 m/s, while the car travels at a constant velocity of 100 km/hr. The car has a width of 3m and a length of 10 m. How far does the car travel while the ball is passing overhead?

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 , v_ball = 3 m/s.

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

Velocity of car , v_car = 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...

Is the U.S. in a stronger or weaker economic and political position in the world because of globalization, or some of both? Why? What are the specific benefits to the U.S. from globalization? In what ways has globalization hurt the U.S.? How competitive do you think the U.S. will be relative to other countries over the next several decades? What will likely happen to absolute (rather than relative) standards of living in the U.S. in the years to come? Why?
