The Universal Law of Gravity states that the force of gravity acts between all objects. Nonetheless, you never feel that the fri

If your mass is 50 kg (you weigh 110 pounds), and the mass of the refrigerator
is 100 kg (it weighs 220 pounds), and you're standing so that the center of
the frig and the center of you are 1 meter apart (about 3 feet), then the force
of gravity between you and the frig is about 0.0000012 ounce.  That's why.

The right-hand rule predicts the direction of the force on a positively charged object moving in a gravitational field true fals
eimsori [14]
The statement above is FALSE.
The right hand rule is used in physics to predict the direction of the force on a charged object moving in a MAGNETIC FIELD. The right hand rule is used to relate the relationship between the magnetic field and the forces that are exerted on the moving objects in the field. Using the right hand rule, for a positively charged object that is moving in an electric field, the pointer finger will point in the direction the charged object is moving, the middle finger will point in the direction of the magnetic field and the thumb will point in the direction of the magnetic force that is pushing the charged object.

At the lowest point in a vertical dive (radius = 0.58 km), an airplane has a speed of 300 km/h which is not changing. Determine
murzikaleks [220]

Answer:

The centripetal acceleration is a = 11.97 \ m/s^2

Explanation:

From the question we are told that

     The radius  is r =  0.58 \ km =  0.58 * 1000  =  580 \ m

      The speed is v  = 300\ km /hr =  \frac{300 *1000}{1 * 3600 }  =  83.33 \ m/s

The centripetal acceleration of the pilot is mathematically represented as

       a =  \frac{v^2 }{r}

substituting  values

      a =  \frac{(83.33)^2 }{580}

     a = 11.97 \ m/s^2

What's needed to know
Diano4ka-milaya [45]
You're a little late.  But if you want some short, quick rules, then these are
a couple that I would take in with me (stored only in my brain, of course):

-- If something is not accelerating or moving at all, then all the forces on it
must add up to zero.    That could even mean a hanging rope.

-- In a vertical rope, the tension in it is the same everywhere in the rope.
The tension is the weight of whatever is hanging from the bottom.

That's really all I'm sure of, based on your hazy, fuzzy description of
what you've been doing in class.  I don't want to get into things that
you might not have learned yet, and confuse you.
