Which of these would have the lowest albedo? A field of freshly fallen snow

A deep lake in a volcanic crater

A forest of green trees

A sandy desert

Aforce of 240.0 n causes an object to accelerate at 3.2 m/s2. what is the mass of the object?

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?

If anyone who can me with this hw? i would really appreciate it
