Answer:
<em>The less mass an object has, the </em><u>less</u><em> its gravitational [force.]</em>
Explanation:
Newton's Law of Gravity states that 
. The two <em>m</em> values are the objects' masses, G is the gravitational constant, and <em>r</em> is the distance between the objects' centers. Notice how the mass values are in the fraction's <em>numerator</em>? That means <em>increasing</em> the mass of one or both objects <em>increases</em> 
. That also implies the inverse; <em>decreasing</em> the mass of one or both objects <em>decreases</em> !
I hope this helps you understand this concept a little more! Have yourself a fantastic day, 'kay?
Answer:
Magnetic flux, 
Explanation:
It is given that,
Magnitude of the magnetic field, B = 0.078 T
Radius of circular loop, r = 0.1 m
The field is oriented at an angle of θ = 25° with respect to the normal to the surface. The magnetic flux through the surface is given by :
or
So, the magnitude of magnetic flux through the surface is 
. Hence, this is the required solution.
According to research, none of these men were executed for believing that Earth revolves around the sun. Nicolaus Copernicus was the first to believe in the heliocentric view of the current solar system, but he was not killed for that view, but he died of natural means. Galileo Galilei was punished because of the heliocentric view but was only put under house arrest, and not killed. Giordano Bruno was indeed burned at stake, but it was not for his view on heliocentrism.
Answer:
The general equation of movement in fluids is obtained from the application, at fluid volumes, of the principle of conservation of the amount of linear movement. This principle establishes that the variation over time of the amount of linear movement of a fluid volume is equal to that resulting from all forces (of volume and surface) acting on it. Expressed in This equation is called the Navier-Stokes equation.
The equation is shown in the attached file
Explanation:
The derivative of velocity with respect to time determines the change in the velocity of a particle of the fluid as it moves in space. It also includes convective acceleration, expressed by a nonlinear term that comes from convective inertia forces). With this equation, Stokes studied the motion of an infinite incompressible viscous fluid at rest at infinity, and in which a solid sphere of radius r makes a rectilinear and uniform translational motion of velocity v. It assumes that there are no external forces and that the movement of the fluid relative to a reference system on the sphere is stationary. Stokes' approach consists in neglecting the nonlinear term (associated with inertial forces due to convective acceleration).
Answer:
123.48J
Explanation:
Given parameters:
Mass of the ball = 2.8kg
Height = 4.5m
Unknown:
Potential energy = ?
Solution:
The potential energy is the energy due to the position of a body. It is mathematically given as;
P.E = mgh
m is the mass
g is the acceleration due to gravity
h is the height
Now insert the parameters and solve;
P.E = 2.8 x 4.5 x 9.8 = 123.48J
