A quartz crystal votec berates with a frequency of 62,621. What is the speed of the crystal’s motion?

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

uranium fissions/breaks up giving out energy and neutrons

the higher the current the higher the mag field around it the higher the influence on the compass

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
