Answer: a. Quadruple
Explanation:
Gravitational force = Gm1m2/r^2
(Where m1 is the mass of earth, m2 is my mass and r is the radius of earth and G is the gravity constant)
Weight = m2g
(Where g is the acceleration due to gravity)
Gm1m2/r^2 = m2g
Twice the masses
F = G(2m1)(2m2)/r^2
F = 4Gm1m2/r^2
The gravitational force has increased 4 times, this means that my weight on earth will quadruple
Elapsed Time=Time(final)-Time(initial)
The elapsed time for Trial B is 3 seconds.
Average speed=distance traveled/elapsed time
The average speed for Trial B is 1.3 m/s.
hope i helped
Answer:
a. Liquid state
b. At point R. The physical state of water at its boiling point temperature of 100 degree Celsius will be both liquid state as well as gaseous state.
c. at 110 degrees it is in gaseous state
Answer:
C) one-half as great
Explanation:
We can calculate the acceleration of gravity in that planet, using the following kinematic equation:
In this case, the sphere starts from rest, so . Replacing the given values and solving for g':
The acceleration due to gravity near Earth's surface is . So, the acceleration due to gravity near the surface of the planet is approximately one-half of the acceleration due to gravity near Earth's surface.
<span>Matter is c) something that has mass and occupies space. Everything in our known universe takes up space, and everything is made up of matter. Matter as a concept is not something that can have any unit of measurement put upon it. </span>
