Answer:

2. decreasing the distance of the space shuttle from Earth

Explanation:

To increase the gravitational force on a space shuttle, it is a good thing to decrease the distance of the space shuttle from the earth.

This is based on the Newton's law of universal gravitation which states that "the gravitational force between two bodies is a directly proportional to the product of their masses and inversely proportional to the square of the distance between them".

 Mathematically;

           F  = \frac{G m_{1} m_{2} }{r^{2} }  

G is the universal gravitation constant, it cannot be changed

m is the mass of the body

r is the distance

  Since the distance is inversely proportional, is we reduce it, the value of the gravitational force will increase.

A particle accelerator fires a proton into a region with a magnetic field that points in the +x-direction (a) If the proton is m
pochemuha

Answer:

a) -z direction, b) +z direction, c) F=0  

Explanation:

The magnetic force is given by the expression

        F = q v x B

the bold indicate vectors, this equation can be separated in its module

        F = a v B sin θ

and where θ is the angles between the speed and the magnetic field.

The direction of the force can be found with the right-hand rule. For a positive charge, the thumb goes in the direction of speed, the fingers extended in the direction of the magnetic field and the palm points in the direction of the force, if the charge is negative the force is in the opposite direction.

a) Let's apply this to our case

the proton is positively charged

moves in the direction of + x

The magnetized field goes in the direction of y

therefore applying the right hand rule the force must be in the direction of the negative part of the z-axis (-z)

The right-hand rule is used to find this address.

b)  in this case it indicates that the proton moves in the recode of -y

again we apply the right hand rule and the force is in the direction of + z

c)   The proton moves in the x direction

In this case the force is zero because the angle between the field and the speed is zero and the sine is zero, therefore the force is zero

If a scale of the solar system was built where 1 mm equaled 1 mile, could the model be practically built in a city?
Y_Kistochka [10]
No, it couldn't be.
On that scale, Neptune would be almost 1,740 MILES from the sun.
ON THAT SCALE !
