Centrifical force seems to assert that the faster the rotation, the lower the gravitational field but people always have told me the opposite. How come. Which is it?

rotate at the equator and if so, in which direction?
Do neighbours, living on opposite sides of the equator, observe water draining in different directions. Now I'm talking about people living very near, north and south of, the equator.

I need help with problem solving but have answers...

A 2.50 g bullet, traveling at a speed of 425 m/s, strikes the wooden block of a ballistic pendulum, such as that in figure 7-17 in your text. The block has a mass of 215 g. Find the speed of the bullet/block combination immediately after the collision.

I need help working out problems but I have the answers so your help is appreciated..

Two brothers, Dustin and Parker, have a combined mass of 168 kg. At an ice skating rink, they stand close together on skates, at rest and facing each other, with a compressed spring between them. the spring is kept from pushing them apart because they are holding each other. When they release their arms, Dustin moves off in one direction at a speed of 0.90 m/s, while Parker moves off in the opposite direction at a speed of 1.2 m/s. Assuming that friction is negligible, find Dustin’s mass.

Here is another physics problem... I have answers need help problem solving

A projectile of mass 0.750 kg is shot straight up with an initial velocity of 18.0 m/s. If the projectile rises to a maximum height of only 11.8 m, determine the magnitude of the average force due to air resistance.

some of the surgeons and consultants working in the nhs. My daughter recently underwent an exploratory examination under anesthetic and was so upset by the rudeness displayed by her constultant when he came to see her after her procedure. She was devastated by his attitude and has difficulty in understanding why he was so very rude to her.
