No it's the quite opposite simple
Answer:
a) about 14.577 kg
b) 300 N
Explanation:
b) In order for the acceleration to be the same for each mass, the 800 N force must be divided between the boxes in proportion to their mass. That is, the net force on the 5M mass must be 5/8 of the total force, or 500 N. Then the tension in the rope is 800 N -500 N = 300 N, which is 3/8 of 800 N.
Tension: 300 N
__
a) The total mass is 8M, and the total normal force on the floor is ...
F = ma = (8M)(9.8 m/s^2)
The friction force is 0.7 times this, and is equal to the 800 N force pulling on the boxes.
800 N = (8M)(9.8 m/s^2)(0.7)
M = 800/(8·9.8·0.7) kg ≈ 14.577 kg
To solve this, you subtract the initial volume from the final volume. So, 29.5 mL minus 25.0 mL is 4.5 mL. Technically, at this point you need to say 4.50 mL, because of sig figs. The volume of the stone will not be in mL, because the stone is not a liquid or a gas, so you must convert it to cm3. So, your answer is (a), 4.50 cm3.
Hope this helps!
Answer:
Explanation:
According to Gauss's Law, the electric flux of a charged sphere is the electric field multiplied by the area of the spherical surface:
This is identical to the electric flux of a point charge located in the center of the sphere.

The only one way that heat can move is: From
higher temperature
to lower temperature, never the other way.
Examples:
-- When you put an ice cube into a glass of warm soda, heat never moves
out
of the ice cube into the soda, making the soda warmer.</span>
-- When you mix cold water with warm water, heat never moves out of the
cold water into the warm water, causing ice to appear and the warm water
to get warmer.
-- When you blow your breath across a spoonful of hot soup, the soup
never draws heat out of your breath, chilling your breath and boiling the
soup on the spoon.
-- When you step into a warm steaming bubble bath, heat never moves
from your body into the hot bath, causing your tootsies to shiver and the
bath to get even hotter.
