Answer:
1.F is the electrostatic force between charges (in Newtons),
2.q₁ is the magnitude of the first charge (in Coulombs),
3.q₂ is the magnitude of the second charge (in Coulombs),
4.r is the shortest distance between the charges (in m),
5.ke is the Coulomb's constant. It is equal to 8.98755 × 10⁹ N·m²/C² .
The plate that is covering most of the two continents
is the Eurasian plate.
The continents are
<span><span>
1. </span><span> Europe</span></span>
<span><span>
2. </span><span> Asia</span></span>
The Eurasian plate is a tectonic plate that amasses
the whole continent of what others call as “Eruasia”.
It takes part of the oceanic crust that starts from
the Mid-Atlantic Ridge and extends itself to northward of the Gakkel Ridge. The
size of this plate is for about 67,800,000 km according to statistics and
geography.
Answer:
The focal length of eyepiece is 3.68 cm.
Explanation:
Given that,
Distance = 19 cm
Focal length = 5.5 mm
Magnification = 200
Object distance = -25 cm
We need to calculate the focal length
Using formula of magnification
Put the value into the formula
Hence, The focal length of eyepiece is 3.68 cm.
Car with a mass of 1210 kg moving at a velocity of 51 m/s.
2. What velocity must a 1340 kg car have in order to have the same momentum as a 2680 kg truck traveling at a velocity of 15 m/s to the west? 3.0 X 10^1 m/s to the west.
Hope i helped
Have a good day :)
