Answer:

They are deflected as Earth’s magnetic field exerts force on them.

Explanation:

(Not for cheating, Just to help)

As solar wind approaches Earth, what happens to the charged electrons?

They are absorbed as Earth’s magnetic field exerts force on them.

They grow stronger as Earth’s magnetic field exerts force on them.

They grow weaker as Earth’s magnetic field exerts force on them.

They are deflected as Earth’s magnetic field exerts force on them.

Naddik [55]

I'm afraid you're not paying attention.  This question is loaded with
all the important words, and you don't recognize Newton's second
law of motion.  Didn't you notice the  "force", "acceleration", and
"mass" all over the place in there ?

Newton's 2nd law:      Force = (mass) x (acceleration)

The answer is going to be 'mass', so let's divide
each side of Newton's law by 'acceleration':

                                   Mass = (force) / (acceleration)

Now, just write in the numbers that the question gave you:

                  force =  60 newtons
       acceleration =  4 m/s²

Here's the equation again:     Mass = (force) / (acceleration)      

                                                       = (60 N) / (4 m/s²)

                                                       =  15 kg .

Ground reaction force acting on carter
mezya [45]
We don't know Carter, and we don't know where he is or what
he's doing, so I'm taking a big chance speculating on an answer.

I'm going to say that if Carter is pretty much just standing there,
or, let's say, lying on the ground taking a nap, then the force of
the ground acting on him is precisely exactly equal to his weight.

A point on a wheel of radius 40 cm that is rotating at a constant 5.0 revolutions per second is located 0.20 m from the axis of
Margarita [4]

Answer:

197.2 m/s^2

Explanation:

The centripetal acceleration of a point moving by circular motion is given by:

a=\omega^2 r

where

\omega is the angular velocity

r is the distance from the axis of rotation

The point on the wheel makes 5.0 revolutions per second, so the frequency is

f=\frac{5}{1}=5 Hz

and the angular velocity is

\omega=2\pi f = 2\pi (5)=31.4 rad/s

While the distance of the point from the axis of rotation is

r=0.20 m

Substituting, we find the acceleration:

a=(31.4)^2(0.20)=197.2 m/s^2

Why do the lights in your home come on almost instantaneously when you turn on the switch?
arlik [135]

Answer:

here you go

Explanation:

Why do your lights actually come on almost instantaneously? ... Wiring the house in parallel does not make a difference – there is no current flowing through the light bulb when the switch is off no matter how the house is wired. If there were a current already, the light would be on!
