Sort the following forces as relevant or not relevant to this situation. The symbols are defined as follows: normal force = n⃗ ,

tension force = T⃗ , horizontal force of the road on the car = F⃗ rc, horizontal force of the road on the truck = F⃗ rt, weight = w⃗ , force of the car pushing on the truck = F⃗ ct, and force of the truck pushing on the car = F⃗ tc.

How much work does the electric field do in moving a proton from a point with a potential of +125 v to a point where it is -55 v
777dan777 [17]
The work W done by the electric field in moving the proton is equal to the difference in electric potential energy of the proton between its initial location and its final location, therefore:
W= qV_i - qV_f
where q is the charge of the proton, q=1 e = 1.6\cdot 10^{-19}C, with e being the elementary charge, and V_i = +125 V and V_f = -55 V are the initial and final voltage.

Substituting, we get (in electronvolts):
W=e(125 V-(-55 V))=180 eV
and in Joule:
W=(1.6 \cdot 10^{-19})(125 V-(-55V))=2.88 \cdot 10^{-17}J

How is the Earth's magnetic field like a bar magnet's magnetic field?
valina [46]
In the outer layers  of earths atmosphere gases are in ionized state primarily on  account of cosmic rays . as earth rotates , strong electric current are set up due to movement of ions . these currents form earth magnetic field . and thus two equal and opposite poles of earth formed

A person is standing on a spring bathroom scale on the floor of an elevator which is moving up and slowing down at the rate of 2
Alinara [238K]

Answer:

923.44N

Explanation:

Obviously Fn cannot equal Fg since the elevator is moving up  

Where Fn is the force read on the scale

Fg is gravitational force=mg=77.6 x 9.8=760.48N

So we use this equation:  

Fnet = Fn - Fg  

ma = Fn - mg

77.6 x 2.1 = Fn – 760.48

162.96N = Fn – 760.48N  

923.44 N = Fn

The answer is 923.44 N

1. The successful launch of communication satellites

2.More people will be interested in studying science

But science would probably be focused on space exploration and there will probably be less scientists in other fields such as chemistry.
