Take the ratio of the moon’s acceleration to the sun’s and comment on why the tides are predominantly due to the moon in spite of this number. calculate the magnitude of the acceleration due to gravity on the surface of earth due to the moon. (b) calculate the magnitude of the acceleration due to gravity at earth due to the sun. (c) take the ratio of the moon's acceleration to the sun's and comment on why the tides are predominantly due to the moon in spite of this number.

Explanation:

G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²

= Mass of Moon =

= Mass of Sun =

= Distance between Moon and Earth =

= Distance between Sun and Earth =

Acceleration due to gravity is given by

The magnitude of the acceleration due to gravity on the surface of Earth due to the Moon is

The magnitude of the acceleration due to gravity at Earth due to the Sun is

Dividing the equations we get

The acceleration due to gravity by the Sun is 184.54 times the acceleration of the Moon.

The Moon is still responsible for the tides because of there being a difference in the gravity exerted on Earth's near and far side.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

pretty sure it's false
