The mass of the whole object is equal to the sum of all its parts A. Law of Conservation of Energy B. Law of Conservation of Mas

Fiesta28 [93]

Answer:

B. Law of Conservation of Mass

Explanation:

In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system.

Three very small spheres of mass 2.50 kg, 5.00 kg, and 8.00 kg are located on a straight line in space away from everything else

Aliun [14]

Answer:

The net gravitational force it exerts is $F_{net}=9.66*10^{-8}N$

Explanation:

Newton's Law of Gravitation can be written as

$F=\frac{Gm_{1}m_{2}}{r^{2} }$

where G is the Gravitational Constant, m1 and m2 are the masses of two objects, and r is the distance between them. In this case, the spheres are loacted in straight line, so instead of a vector r, we have a distance x in meters. The distances and masses are given in the problem, and the smaller sphere is between the other two spheres. This means the sphere 1 is in the middle, the sphere 2 is on the left of 1, and the sphere 3 is on the right of 1, so

$F_{21} =\frac{Gm_{1}m_{2}}{x_{21}^{2} }$ is the force that 2 feels because of 1, and

$F_{31} =\frac{Gm_{1}m_{3}}{x_{31}^{2} }$ is the force that 3 feels because of 1.

If we replace the data in those previous equations, we have that

$F_{21} =\frac{G(2.5)(5) }{(0.08)^{2} }=1.3*10^{-7}N$

$F_{31} =\frac{G(2.5)(8) }{(0.2)^{2} }=-3.34*10^{-8}N$

Finally, adding both results, the net force the sphere 1 exerts is

$F_{net}=9.66*10^{-8}N$

Be sure to show all 4 steps for each of the problems below.

Kisachek [45]

Answer:

1=920

2=2300

Explanation:

from the question,

M¹=23

H¹=4

g=10(constant)

using the formula

P. E,= mgh

P. E= 23×10×4=920

P. E=23×10×10=2300

Modifiable strength improvement factors include all of the following except...??

Alla [95]

Answer:

Muscle size and training specifiicty

Explanation:

It depends on all other factors such as anatomy and psychology, muscle fiber recruitment, motor pattern development and muscle memory but to increase modifiable strength, size plays no big role.
