5) A projectile has a kinetic energy of 1566 joules. If it is traveling through the air with a velocity of 50.0 m/s, what is its mass?

Avery long solenoid of inner radius 2.75 cm creates an oscillating magnetic field of the form = for this solenoid, =0.00425 t and =319 rad/s. (a)what is the maximum value of the induced electric field at a perpendicular distance 1.45 cm from the axis of the solenoid? (b) what is the maximum value of the inducted electric field at a point 5.85 cm perpendicular from the axis of the solenoid?

Ihave a density of 1.61g/cm^3 and a mass of 28g. find the missing value

How does an observation about an object differ from an inference about that object
