777dan777 [17]3 years ago
5 0

Answer:

0.50 kg moving at 10 m/s

Explanation:

          mv = p

 0.50(10) = 5.0 kg•m/s

5.0(0.50) = 2.5 kg•m/s

         1(2) = 2 kg•m/s

 0.40(10) = 4.0 kg•m/s

How did the rock of the Great Plains and Rocky Mountains form? They gave me two sentences and I have to eliminate one
Helen [10]

Answer:

Formation of Plains

As mountains and hills erode, gravity combined with water and ice carry the sediments downhill, depositing layer after layer to form plains. Rivers form plains through related processes. As rivers erode rock and soil, they smooth and flatten the land they pass through.

The surface charge density on an infinite charged plane is −1.70 x 10^−6 C/m^2 . A proton is shot straight away from the plane a
goldfiish [28.3K]

Answer:

Acceleration of proton will be -9.197\times 10^{12}m/sec^2

Explanation:

We have given surface charge density of an infinite charged plate \sigma = -1.70\times 10^{-6}C/m^2

Electric field due to infinite sheet charge is given by E=\frac{\sigma }{2\epsilon _0}=\frac{-1.7\times 10^{-6}}{2\times 8.85\times10^{-12}}=-0.096\times 10^6=-9.6\times 10^4N/C

Charge in proton is given by e=1.6\times 10^{-19}C

So force on proton F=qE=1.6\times 10^{-19}\times -9.6\times 10^4=-15.36\times 10^{-15}N

Mass of proton m=1.67\times 10^{-27}kg

According to newtons second law force F = mass × acceleration

So -15.36\times10^{-15}=1.67\times 10^{-27}a

a=-9.197\times 10^{12}m/sec^2
