This is Newton's second law of motion.

It states that Force exerted on a moving object is directly proportional to its product of mass and acceleration.

i.e Force(F) = Mass(M) × Acceleration(A)

Because Force is constant here, reducing the weight of the body the force is applied to consequently reduces its mass.

If mass is reduced, the body's acceleration increases hence increasing its speed.

That is why the 40N dumbbell move faster.

Convert 1nanosecond in to its SI init

<em>Convert 1nanosecond in to its SI init</em>

<em>In SI units, nano is 1000th part of micro which in turn is 1000th part of mini which in turn is 1000th part of main unit. Now, when you affix nano to any unit, here in case, second, it means that you are referring to 1000th part of 1000th part of 1000th part of second or in short, 1000000000th(10^9) part of a second.</em>

What's the difference between meteoroids, meteorites, and meteors?
SVEN [57.7K]

You're talking about a grain of sand or a stone or a rock that's drifting in space, and then the Earth happens to get in the way, so the stone falls down to Earth, and it makes a bright streak of light while it's falling through the atmosphere and burning up from the friction.

-- While it's drifting in space, it's a <em>meteoroid</em>.

-- While it's falling through the atmosphere burning up and making a bright streak of light, it's a <em>meteor</em>.

-- If it doesn't completely burn up and there's some of it left to fall on the ground, then the leftover piece on the ground is a <em>meteorite</em>.

The volumes of the block is 10,500 mL and density is 8.52 g/mL. Find the block's mass Don't forget units and a space
Schach [20]

Answer:

<h2>89,460 g</h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question we have

mass = 8.52 × 10,500

We have the final answer as

<h3>89,460 g</h3>

Hope this helps you
