The Tonga Trench is located at the tectonic boundary between the Pacific Plate and the Indian-Australian Plate.
It is an Oceanic trench that is located in the south-west Pacific Ocean. It is actually the deepest trench of the southern Hemisphere and the second deepest on Earth.
Answer:
Approximately 3.03 seconds.
Explanation:
The distance traveled in the vertical direction is given by the kinematic equation:
Where <em>v</em>_<em>iy</em> and <em>a</em> are the initial velocity and acceleration of the object, respectively, in the vertical direction.
Because the rock is thrown horizontally, there is no horizontal velocity. Therefore:
The vertical acceleration is simply gravity <em>g. </em>This, this yields the general equation:
Substitute 45 m for <em>y</em> and solve for time <em>t:
</em>
Therefore, it will take approximately 3.03 seconds for the rock to fall 45 meters vertically.
Hello!
Using the equation for the electric field produced by a source charge:
E = Electric Field Strength ( 2.86 × 10⁵ N/C)
k = Coulomb's Constant ( 8.99 × 10⁹ Nm²/C²)
q = Charge of source charge (3 μC = 0.000003 C)
r = distance of test charge from source charge (m²)
We can rearrange the equation to solve for distance to make plugging in values easier. (Isolate for 'r').
Plug in the given values.
Answer:
8.87 m/s^2
Is the same for both planets
Explanation:
Hello!
The surface gravity can be calculated from Newton's Law of Gravitation and Newton's Second Law :
ma = F =G Mm/r^2
Solving for a:
a = G M/r^2
And the surface graity g = a(R), that is, the surface gravity is equal to the acceleration evaluated at the radius of the planet:
g = G M/R^2
Since G is a constant, we need to evaluate M/R^2 for both to know in which planet the surface gravity is the geratest:
M_u/R_u^2 = 1.323 x 10^11 kg/m^2
M_v/R_v^2 = 1.323 x 10^11 kg/m^2
It turns out that the surface gravity in both planets is the same! which is:
g = G M_u/R_u^2
= ( 6.67408 × 10-11 m^3 / (kg s^2) ) *( 1.323 x 10^11 kg/m^2)
= 8.87 m/s^2
*as you can check on google*
You would feel the same weigth in both planets, however you wil feel lighter in these planets than in earth.
