Answer:
At a convergent boundary where both plates are continental, mountain ranges grow and earthquakes are common. At a transform boundary, there is a transform fault and massive earthquakes occur but there are no volcanoes. Processes acting over long periods of time create Earth's geographic features.
Explanation:
Answer:
230.4 N
Explanation:
Applying,
F = kqq'/r²..................... Equation 1
Where F = Electric force, k = Coulomb's constant, q = charge in the ballon, q' = charge in the denium, r = distance between the charges.
From the question,
Given: q = -8.0×10⁻⁶ C, q' = +8.0×10⁻⁶ C, r = 0.05 m
Constant: k = 9×10⁹ Nm²/C²
Substitute these values into equation 1
F = (9×10⁹×8.0×10⁻⁶×8.0×10⁻⁶ )/0.05²
F = (576×10⁻³)/0.0025
F = 230.4 N.
. For an elastic head-on (assumed) collision between equal masses, they simply swap velocities. The final velocities of objects 1 and 2 are 0 and v, respectively.
<span>2. mv = (2m)u </span>
<span>where u = final velocity. Then u = v1 = v2 = v/2 </span>
<span>3. Initially, p = (2m)v </span>
<span>final p = 2mv = 2mv1 + mv2 </span>
<span>But for an elastic head-on collision, we know that the </span>
<span>relative velocity of approach = relative velocity of separation, or </span>
<span>v = v2 - v1 </span>
<span>v2 = v + v1 </span>
<span>plug into final p: </span>
<span>2mv = 2mv1 + m(v + v1) = 2mv1 + mv + mv1 </span>
<span>mv = 3mv1 </span>
<span>v1 = v/3 </span>
<span>v2 = v + v/3 = 4v/3 </span>
<span>4. initial p = mv </span>
<span>final p = mv = (m + 3m)u = 4mu </span>
<span>u = v1 = v2 = v/4</span>
