What is the mass of an object that accelerates at 5 m/s2 when pushed with 100 N?
dangina [55]

Answer:

the answer is 20g

Explanation:

Data:

acceleration:5m/s2

force:100N

mass:?

solution:

force: mass*acceleration

mass: force divided by acceleration

mass:100/5

mass:20g

or another way of solving it is

force: mass*acceleration

100:mass*5

100/5 : mass

20g:mass

Dovator [93]

Answer:

100m

Explanation:

10 x 10 = 100m

area of velocity time graphs gives displacement.

im not sure if the distance is the same.

An atom undergoes nuclear decay, but its atomic number is not changed.
andreev551 [17]

Answer:

A. Gamma decay

Explanation:

A form of nuclear decay in which the atomic number is unchanged is a gamma decay.

The atom has undergone a gamma decay.

In a gamma decay, no changes occur to the mass and atomic number of the substance.

  • Gamma rays have zero atomic and mass numbers.
  • When they cause decay, they cause no change to the mass and atomic numbers.
  • They simply produce gamma rays during such reactions and these rays are very energetic.

A straightforward method of finding the density of an object is to measure its mass and then measure its volume by submerging it
Veseljchak [2.6K]

Incomplete question as the unit of volume is not written correctly.So the complete question is here:

A straightforward method of finding the density of an object is to measure its mass and then measure its volume by submerging it in a graduated cylinder. What is the density of a 240-g rock that displaces 89.0 cm³?

Answer:

d_{Density}=2.7g/cm^{3}

Explanation:

Given data

Mass m=240g

Volume V=89.0 cm³

To find

Density d

Solution

If rock displaces 89.0 cm³ of water means volume of rock is also 89cm³

So

d_{Density}=\frac{mass}{volume}\\d_{Density}=\frac{240g}{89.0cm^{3} } \\d_{Density}=2.7g/cm^{3}
