Answer:
See the answers below
Explanation:
This problem and its respective questions can be easily solved using Newton's law of universal gravitation. Which can be calculated by means of the following expression.
where:
G = it is the universal gravitation constant. = 6.673 x 10⁻¹¹ [N*m²/kg²]
m1 = mass of the first body [kg]
m2 = mass of the second body [kg]
r = distance among the bodies [m]
a. the mass of one is doubled?
When this happens we see that the force is increased twice as well, since the mass is in the numerator of the expression.
b. The masses of both are doubled?
If both masses are doubled the force is increased to four times its original value since the terms of the masses are in the numerator of the expression.
c. The distance between them is doubled?
In this case the force is decreased to half of its original value, since the distance is in the denominator of the expression of universal gravitation.
Scientists can tell this by looking at seismic waves released by earthquakes. ( if you need me to elaborate more ask)
The answer to this question is "LIES BELOW THE SURFACE" happens or occurs. When one of the main differences between the two which is the Intaglio and the other one is the relief printing processes is that with the Intaglio the ink LIES BELOW the surface of the printing plate.
Answer:
Best at conductioning heat- Solid
Explanation:
<u><em>In order for heat to conduct it has to pass from particle to particle.</em></u>
A solid has particles closely compacted so the heat is able to tranfer quickly from particle to particle.
A liquid has isn't as compacted it actually has enough space to slide over each other
A gas has very far apart particles and takes heat longer to transfer from one particle to another.
Answer:
A. 11.5 m
Explanation:
Given,
The initial velocity of the soda cap, u = 15 m/s
The soda bottle cap is projected vertically upwards,
Hence, the angle formed with the ground, Ф = 90°
The maximum height of the projectile is given by the formula,
Substituting the given values in the above equation
= 11.5 m
Hence, the maximum height of the cap is h = 11.5 m
