Answer:
Explanation:
Force = (mass) · (acceleration)
= (1,000 kg) · (9.8 m/s²)
= 9,800 newtons
Answer: From the location of elements in the periodic table you can predict it's properties. The elements are arranged in the modern periodic table in the order of increasing atomic number. The rows are called periods and the columns, groups. ... These elements have the same number of electrons in their outermost (valence) shells.
Explanation:
atomic 13 tells us that the atomic weight which is 26.982. and the m.p. is 660 degrees celcius
Answer:
Answer should be (B)
Explanation:
If the forces on an object are balanced (or if there are no forces acting on it), this is what happens: a stationary object stays still. a moving object continues to move at the same speed and in the same direction.
ALSO: forces acting upon an object are balanced, then the object will maintain its state of motion. To maintain the state of motion is to keep the current speed and direction. But if the forces are not balanced, the object will change its state of motion.
Because it is really hard and rocks can't be visible or vibrate
The principle of moment can be verified when two known masses are suspended on a uniform meter rule.
<h3>What is principle of moment?</h3>
The principle of moment states that, the sum of clockwise moment is equal to the sum of the anticlockwise moment.
The principle of moment is verified when two known mass (m1 and m2) are suspended on a uniform meter rule.
The clockwise moment will be equal anticlockwise moment of the two masses.

Thus, the principle of moment can be verified when two known masses are suspended on a uniform meter rule.
